7 EN 32 217-2-1 V1.2.1 (27-6) 1 Scope The present document summarizes all system-dependent requirements for Point-to-Point (P-P) equipment in applications deployed in bands where frequency co-ordination is generally applied. These requirements are introduced in two different clauses sub-sets: Main requirements are requirements that are also related to the "essential requirements" under article 3.2 of the R&TTE Directive [1] and further detailed in EN 32 217-2-2 [16]. Complementary requirements are requirements that are not related to essential requirements under article 3.2 of the R&TTE Directive [1]. Nevertheless they are considered having been commonly agreed for proper system operation and deployment when specific deployment conditions or compatibility requirements are present. Compliance to all or some of these requirements is made on a voluntary basis. Description and limits for parameters relevant to essential requirements under article 3.2 of R&TTE Directive [1] are given in EN 32 217-2-2 [16]. For other system-dependent parameters where standardization is required but that do not affect the R&TTE Directive "essential requirements" mentioned above, description and limits are detailed in the present document in the annexes A to G, subdivided by frequency band or specific applications. The present document deals with Radio Frequency (RF) and base-band equipment characteristics; antenna system requirements are covered in EN 32 217-4-1 (see bibliography) and EN 32 217-4-2 (see bibliography). The present document does not cover test procedures and test conditions which are set out in EN 31 126-1 [14]. As the maximum transmission rate in a given bandwidth depends on system spectral efficiency, different equipment classes are defined in EN 32 217-2-2 [16]. The spectral efficiency classes are indicative only and do not imply any constraint to the actual modulation format, provided that all the requirements in the relevant parts of this EN 32 217 series are met. In some cases, where within the same spectral efficiency class there are different applications, (e.g. for multi-channel trunk or single channel operation), that justify different radio frequency parameters, two different equipment "types" (e.g. type 1 and 2) are provided. Guidance on the definition of radio parameters relevant to the essential requirements under article 3.2 of R&TTE Directive [1] for DFRS may be found in TR 11 56 (see bibliography). Technical background for most of the parameters and requirements referred to in this EN 32 217 series may be found in TR 11 36-1 (see bibliography).

1 EN 32 217-2-1 V1.2.1 (27-6) 3.2 Symbols For the purposes of the present document, the symbols given in EN 32 217-1 [15] apply. 3.3 Abbreviations For the purposes of the present document, the abbreviations given in EN 32 217-1 [15] apply. 4 General characteristics For commonality of purpose, systems are sub-divided into families by frequency range of operation; one normative annex is assigned to each family of equipment. There are six families of annexes, referenced from A to F, which may be found in both in the present document and EN 32 217-2-2 [16]: A Frequency bands from 1,4 GHz to 2,7 GHz. B Frequency bands from 3 GHz to 11 GHz (Channel separation up to 3 MHz and 56/6 MHz). C Frequency bands from 3 GHz to 11 GHz (Channel separation 4 MHz). D Frequency bands 13 GHz, 15 GHz and 18 GHz. E Frequency bands from 23 GHz to 55 GHz. F Transmission of packet data and combinations of other signals in bands from 3 GHz to 55 GHz. 4.1 Frequency bands and channel arrangements Frequency bands and channel arrangements, which are relevant for equipment covered by the present document, are defined by ITU-R Recommendations and/or CEPT Recommendations and are referenced in the first table of each annex A through E (i.e. tables A.1 through E.1) of EN 32 217-2-2 [16]. ITU-R Recommendations or CEPT/ECC (see note) recommended frequency channel arrangements, known at the date of publication of this EN 32 217 series, are set out for reference only. In general, the channel arrangement is relevant neither to article 3.2 of the R&TTE Directive [1] nor for other requirements in the present document; only the frequency band, actual channel separation and, in some cases innermost channels separation are relevant for defining the set of parameters and test suites relevant to each system. NOTE: CEPT Recommendations were published until 22 as CEPT/ERC Recommendations; consequently to the restructuring of ERC under new ECC organization, new and revised Recommendations might formally change their reference as ECC Recommendations, without changing their technical content and applicability. Other national or future ITU-R Recommendations or CEPT/ECC Recommendations, set around the same or close to the frequency range of present ITU-R Recommendations or CEPT/ECC Recommendations, are considered applicable to systems assessed against this EN 32 217 series, provided that they use the same channel separation. Specification and tests of wide radio-frequency band covering units and multirate equipment are placed in normative annex G of EN 32 217-2-2 [16]. Whenever applicable, it is also valid for assessing parameters specified in the present document. 4.2 Special compatibility requirements between systems There shall be no requirement to operate transmitting equipment from one supplier with receiving equipment from another and, depending on the deployment conditions, it shall be possible to operate the system in vertical and/or horizontal polarization, if required by the channel arrangement.

11 EN 32 217-2-1 V1.2.1 (27-6) To be compatible with certain constraints given by existing installations and/or deployments already made with systems from other supplier or for different FS applications, new systems on the same path may be subject to additional requirements, other than those derived for a single supplier or same application environment. NOTE: This does not imply that when a single supplier is involved there are no similar requirements; however, they do not need standardization because many other technical and cost-effective solutions might be flexibly adopted under suppliers' own responsibility only. For the purposes of this EN 32 217 series the following set of compatibility requirements between systems has been defined: a) There may be a requirement to multiplex different suppliers' equipment on the same polarization of the same antenna. This will not apply to systems with an integral antenna. b) There may be a requirement to multiplex different suppliers' equipment on different polarizations of the same antenna. This will not apply to systems with an integral antenna. c) There may be a requirement to coexist with analogue systems on adjacent cross-polarized channels on the same route. 4.3 Transmission capacity and spectral efficiency The payload bit rates considered in this EN 32 217 series are commonly tailored to typical PDH and SDH baseband interfaces: 2,48 Mbit/s, 2 2,48 Mbit/s, 8,448 Mbit/s, 2 8,448 Mbit/s, 34,368 Mbit/s, 2 34,368 Mbit/s, 51,84 Mbit/s (STM-), 2 51,84 Mbit/s (2 STM-), 155,52 Mbit/s (STM-1), N 155,52 Mbit/s (N STM-1), STM-N. Only systems in annex A, due to the smaller channel separation provided, are (exceptionally) labelled with typical capacity rate without specific reference to PDH/SDH rates. In the following text these capacities will be simply referred to as 2 Mbit/s, 2 2 Mbit/s, 8 Mbit/s, 2 8 Mbit/s, 34 Mbit/s, 2 34 Mbit/s, STM-, 2 STM-, STM-1, N STM-1 and STM-N. For each system the bit rates related to each class and their relevant channel separation are detailed in the second table of each annex A through E (i.e. tables A.2 through E.2) of EN 32 217-2-2 [16] of this EN 32 217 series. Provided that they meet all requirements of the relevant annex, equivalent PDH or SDH transport rates may be used where appropriate. Such equivalent transport rates may be: N 2 Mbit/s or other PDH rates in place of equivalent higher PDH rates. 14 Mbit/s (including 4 34 Mbit/s) in place of STM-1. Any PDH mapping into STM- or STM-1 frames, as defined in the basic multiplexing schemes. N 2 Mbit/s mapped into SDH VC12 or VC2 transport bit rates (sub-stm- defined, as sstm-1k or sstm-2n capacities, by ITU-T Recommendation G.78 [25]) in place of a PDH rate (e.g. 4 VC12/sSTM14 or 1 VC2/sSTM21 in place of 8 Mbit/s). NOTE: In addition to this general principle, annex D (system D.2) presents specific characteristics for sub-stm- systems in the 18 GHz band. Any other signal (e.g. IP frames or ATM cells, even possibly mixed with PDH capacities) mapping into PDH or SDH frames, according present or future basic ITU-T or multiplexing schemes. The present document is also applicable to other base band interfaces (e.g. packet data interfaces or mixed interfaces) even if multiplexed (including compression algorithms if any) into proprietary frames; for such cases annex F gives the basic rules for applying the conventional PDH/SDH set of parameters to those equipment assessment.

12 EN 32 217-2-1 V1.2.1 (27-6) 5 Main requirements This clause summarizes requirements related to the "essential requirements" under article 3.2 of the R&TTE Directive [1] that are further detailed in EN 32 217-2-2 [16]. However, for some requirements, besides the relevant essential limits set out in EN 32 217-2-2 [16] for the purpose of their separate publishing in the Official Journal of the European Communities (OJEC) under the R&TTE Directive [1], additional, non-essential, more stringent limits are here set out in response to specific compatibility requirements by network operators when deploying new systems on the same routes with existing systems from other suppliers. The specified transmitter and receiver characteristics shall be met with the appropriate baseband signals applied at reference point X' and received from reference point X of figure 1 of EN 32 217-1 [15]. Table 1: Baseband test signals Type of baseband signal interface at X/X' Test signal to be applied according to PDH PRBS ITU-T Recommendation O.151 [26] SDH ITU-T Recommendation O.181 [27] ATM ITU-T Recommendation O.191 [28] Ethernet interface (packet data) IEEE 82.3 [23], IEEE 182.3 [24] Other than the above Relevant standards which the interface refers to 5.1 Transmitter characteristics 5.1.1 Transmitter power The only essential requirement is the Maximum Output Power which is an essential requirement under article 3.2 of R&TTE Directive [1] and is specified in EN 32 217-2-2 [16]. For guidance, in addition to the absolute maximum transmitter power, typical values of transmitter highest power for real equipment, of feeder loss and length, and of antenna diameter and gain are provided in TR 12 243-1 (see bibliography) in order to support inter- and intra- compatibility and sharing analysis. In some frequency bands, or parts of frequency bands, ITU-R Recommendations define specific limits in terms of output power and/or EIRP (or output power and/or EIRP density) in order to improve the compatibility with other Radio Services sharing these frequency bands with the FS. An additional capability for output power level adjustment may be required, for regulatory purposes, in the interface regulations according to article 4.1 of the R&TTE Directive [1], in which case the range of adjustment, either by fixed or automatic attenuators, should be in increments of 5 db or less. In particular, for the band 18 GHz, the FS shall, where practical, implement the appropriate mitigation techniques as required in ERC/DEC()7 [3]. See informative annex H. 5.1.2 Transmitter power and frequency control 5.1.2.1 Transmitter power control (ATPC and RTPC) 5.1.2.1.1 Automatic Transmitter Power Control (ATPC) This functionality is relevant to essential requirements under article 3.2 of R&TTE Directive [1] and is specified in EN 32 217-2-2 [16]. Besides those essential requirements specified in EN 32 217-2-2 [16], ATPC may be requested as mandatory functionality in the licensing conditions for the following purposes: to enhance network density (see note 1); as a mitigation factor for sharing with other Services due to CEPT Decisions (see notes 2 and 3).

13 EN 32 217-2-1 V1.2.1 (27-6) Administrations should explicitly state whether ATPC is used as a regulatory measure for either frequency coordination or as a mitigation technique to protect other services in its radio regulation interface for notification according to article 4.1 of the R&TTE Directive [1]. NOTE 1: In this particular case, as an additional, but non-essential to article 3.2, requirement, it may be specified that transmitter output power meet the spectrum mask limits set out in clause 4.2 of EN 32 217-2-2 [16] throughout the ATPC range. NOTE 2: The first example is in the 18 GHz band, where since there is sharing between FS and FSS, ATPC will become a mandatory feature for all new equipment to be deployed after the date referred by ERC/DEC()7 [3], however, the actual usage of ATPC will be required only where practical and depending on local sharing conditions with satellite services and local deployment conditions in existing networks. The ATPC range is not subject to standardization. NOTE 3: When used as mitigation factor ATPC should not be, in principle, used to enhance network density. 5.1.2.1.2 Remote Transmitter Power Control (RTPC) This parameter is relevant to essential requirements under article 3.2 of R&TTE Directive [1] and is specified in EN 32 217-2-2 [16]. 5.1.2.2 Remote Frequency Control (RFC) This parameter is relevant to essential requirements under article 3.2 of R&TTE Directive [1] and is specified in EN 32 217-2-2 [16]. 5.1.3 Transmitter output power tolerance The only essential requirement is the power tolerance around the nominal output power together with the associated temperature range, declared by the supplier, which is considered essential under article 3.2 of R&TTE Directive [1]. For relevant limits see EN 32 217-2-2 [16]. An additional voluntary requirement may be required where more stringent limits apply according to the specific environmental condition for which the equipment is designed. In this case, when specified, the tolerance of the nominal output power shall be within the limits specified for: Systems operating within classes of weather protected locations defined in EN 3 19-1- [4] to EN 3 19-2-4 [13]; nominal output power, when specified, within ±A db; the value for A is system dependent and is given in the relevant annex(es). Systems operating within non-weather protected locations classes 4.1 and 4.1E and within classes 3.3, 3.4 and 3.5 weather protected locations defined in EN 3 19-1- [4] to EN 3 19-1-4 [8]; nominal output power within ±B db; the value for B is system dependent and is given in the relevant annex(es). In any case, the less stringent tolerance (±B db or the only one when a single tolerance exists), when applied to the operational environmental profile declared by the supplier (i.e. not necessarily an standardized one), is considered essential to article 3.2 and contained in EN 32 217-2-2 [16]. Only voluntary and more stringent tolerances are specified in the present document. 5.1.4 Radio Frequency (RF) spectrum mask The radio frequency spectrum density mask is relevant to essential requirements under article 3.2 of R&TTE Directive [1], the limits for the essential portion of RF spectrum density masks are found in EN 32 217-2-2 [16]. Additional non-essential requirements for spectrum density masks may have to be met in cases where there is a requirement for internal system dependent reasons only. Where more stringent RF spectrum masks are required, they may be found in the relevant annex(es) of the present document.

14 EN 32 217-2-1 V1.2.1 (27-6) The db level shown on the spectrum masks relates to the spectral power density at the carrier centre frequency, disregarding the residual of the carrier (due to modulation imperfection). NOTE: The masks do not include frequency tolerance. Systems specified in annex A are an exception to this general rule; in this case "fo" identifies the nominal carrier frequency and the spectrum mask includes an allowance for frequency tolerance. The spectrum analyser settings for measuring the RF spectrum mask are shown in table 6 of clause 5.2.4 of EN 32 217-2-2 [16]. They are reproduced in table 2 in the present document for the reader's convenience. Table 2: Spectrum analyser settings for RF power spectrum measurement Channel separation (CS) (MHz),3 < CS,3,3 < CS,3,3 < CS,9,9 < CS 12 12 < CS 36 36 < CS Centre fo fo fo fo fo fo frequency Sweep width > 5 CS > 5 CS > 5 CS > 5 CS > 5 CS > 5 CS (MHz) Scan time auto auto auto auto auto Auto IF bandwidth 1 3 1 3 1 3 (khz) Video bandwidth (khz),3,1,1,3,3,3 NOTE: The masks do not include frequency tolerance. Systems specified in annex A are an exception to this general rule; in this case "fo" identifies the nominal carrier frequency and the spectrum mask includes an allowance for frequency tolerance. 5.1.5 Discrete CW components exceeding the spectrum mask limit 5.1.5.1 Discrete CW components at the symbol rate This parameter is relevant to essential requirements under article 3.2 of R&TTE Directive [1] and is specified in EN 32 217-2-2 [16]. NOTE: In some previous ENs more stringent limits were required, due to the possibility of interference on the analogue baseband channels of analogue systems deployed on the same route with digital systems. However these deployments are no longer practical and such requirements are therefore no longer considered appropriate (for new equipment). 5.1.5.2 Other discrete CW components exceeding the spectrum mask limit This parameter is relevant to essential requirements under article 3.2 of R&TTE Directive [1] and is specified in EN 32 217-2-2 [16]. 5.1.6 Spurious emissions - external "External" limit for spurious emissions from transmitters are necessary in order to limit interference into other systems operating wholly externally to the system under consideration (external emissions). This parameter is relevant to essential requirements under article 3.2 of R&TTE Directive [1] and is specified in EN 32 217-2-2 [16]. 5.1.7 Radio frequency tolerance This parameter is relevant to essential requirements under article 3.2 of R&TTE Directive [1] and is specified in EN 32 217-2-2 [16].

15 EN 32 217-2-1 V1.2.1 (27-6) In some cases, as an additional voluntary requirement, more stringent limits apply according to the specific environmental condition for which the equipment is designed. In this case, when specified, maximum radio frequency tolerance shall not exceed: ±Y ppm or ±YY khz, whichever is the more stringent, for operation in weather protected environmental classes 3.1 and 3.2 defined in EN 3 19-1-3 [7]; ±X ppm or ±XX khz, whichever is the more stringent, for operation in other more severe environmental classes defined in EN 3 19-1- [4] to EN 3 19-1-4 [8]. The values of either X or XX and either Y or YY are system dependent and are given in the relevant annex(es). In any case, the less stringent tolerance (±X ppm or ±XX khz, the only one when a single tolerance exists), when applied to the operational environmental profile declared by the supplier (i.e. not necessarily an standardized one), is considered to be essential with respect to article 3.2 of R&TTE Directive [1] and is specified in EN 32 217-2-2 [16]. Only voluntary and more stringent tolerances are specified in the present document. These limits include both short-term factors (environmental effects) and long-term factors (ageing effects). The supplier shall specify the guaranteed short-term part and the expected ageing part. 5.2 Receiver characteristics 5.2.1 Spurious emissions-external This parameter is relevant to essential requirements under article 3.2 of R&TTE Directive [1] and is specified in EN 32 217-2-2 [16]. 5.3 System performance without diversity 5.3.1 BER as a function of receiver signal level This parameter is relevant to essential requirements under article 3.2 of R&TTE Directive [1] and is specified in EN 32 217-2-2 [16]. 5.3.2 Interference sensitivity 5.3.2.1 Co-channel "external" interference sensitivity "External" co-channel interference is considered to be that interference from a system fully independent from the one under test (i.e. a system deployed by another operator in the same geographical area). This parameter is relevant to essential requirements under article 3.2 of R&TTE Directive [1] and is specified in EN 32 217-2-2 [16]. 5.3.2.2 Adjacent channel interference sensitivity This parameter is relevant to essential requirements under article 3.2 of R&TTE Directive [1] and is specified in EN 32 217-2-2 [16]. In addition, for ACCP/CCDP applications of class 4 and class 5B systems in frequency bands below 15 GHz with CS 14 MHz, to cope with differential fading effects on the longer hops in systems operating on adjacent channels on the same route but using different antennas, C/I values up to about 1 db tighter than those reported in EN 32 217-2-2 [16] may be necessary. However, this actually depends on the hop fading occurrence factor and the ATPC range implemented on all adjacent systems (i.e. the higher is the ATPC common range, the lower is the C/I sensitivity need). The relationship of these parameters on hop performance prediction is not identified; therefore specific requirement cannot be defined.

16 EN 32 217-2-1 V1.2.1 (27-6) 5.3.2.3 CW spurious interference This parameter is relevant to essential requirements under article 3.2 of R&TTE Directive [1] and is specified in EN 32 217-2-2 [16]. 6 Complementary requirements This clause considers requirements that are not related to essential requirements under article 3.2 of the R&TTE Directive [1]. Nevertheless, all or some of these requirements are considered useful for proper system operation and deployment when specific deployment conditions or compatibility requirements, as defined in clause 4.2, are present. Compliance to all or some of these requirements is on a voluntary basis. 6.1 Branching/feeder requirements 6.1.1 Waveguide flanges (or other connectors) When flanges (or coaxial types) are required at reference point(s) B, B', C, C', the following types shall be used: UBR/PBR/CBR-XXX flanges according to IEC 6154-2 [18] shall be used for the bands specified in table 3. When the same band appears covered by two different options, both are admitted, provided that adaptors are available. Coaxial connectors can be used, as an option, for all frequency bands (see note). The impedance of the coaxial ports shall be nominally 5 Ω. NOTE: For coaxial connectors a number of popular standards exist; attention is drawn to a range of coaxial connectors referred to in parts 1 and 2 of IEC 6339 [2], IEC 6169-1 [19], CENELEC EN 12215 [2]. However, it should be noted that these standards are not exhaustive.

17 EN 32 217-2-1 V1.2.1 (27-6) 6.1.2 Return loss at equipment antenna port (C/C' reference point) It is frequent practice that equipment without integral antennas are connected to feeder/antenna systems from other supplier. For equipment according to the present document, that uses outdoor radio frequency units, which are likely to have integral antennas or similar technical solutions, without long feeder connections, the impact of return loss at the antenna port on system performance is negligible and does not require (see also note to table 4) standardized limits. For fully indoor systems, which are generally deployed with longer feeder connections to an external antenna, and may be required to operate with respect to compatibility requirements specified in clause 4.2 list items a and b, the minimum return loss depends on the signal bandwidth and modulation complexity. The required values, at point C and C' of figure 1 of EN 32 217-1 [15], over the required RF channels and measured back in the direction to the equipment shall meet the values specified in table 4. Table 4: Return loss at the C and C' port towards equipment for fully indoor system Channel separation (CS) Spectral efficiency class (MHz) 1 and 2 3 and 4 5 and 6 CS 27,5 14 db 18 db 2 db (64 QAM based) 22 db (128 QAM based) 24 db (256 QAM based) 26 db (512 QAM based) 27,5 > CS 13,75 Not required 12 db 16 db 13,75 > CS 7 Not required Not required 1 db 7 > CS Not required Not required Not required NOTE: Not required means that return loss is not an issue for performance but only for potential power loss due to reflection. Even if there might be special cases where RF units designed for outdoor operation are also used in fully indoor conditions, this should be resolved on a case by case basis. For feeder/antenna return loss requirements see EN 32 217-4-1 (see bibliography). 6.2 Intermodulation products Where multi-channel branching system is concerned and where the system is intended to comply with compatibility requirement in clause 4.2, each odd order intermodulation product, caused by different transmitters linked to the same branching system, shall be less than -11 dbm referenced to reference point B of figure 1 of EN 32 217-1 [15] of this EN 32 217 series with an output power per transmitter limited to the maximum power stated by the supplier for the equipment. The reference power shall be the maximum power stated by the supplier for the equipment. This clause is not intended for use with conformance tests, but only, if required, for type tests agreed between user and supplier. The measurement, if any, will be carried out with un-modulated signals of the same power of the average level of the digital signals. 6.3 Transmitter characteristics 6.3.1 Spurious emissions - internal This category covers emissions that, for system compatibility with other systems only, may be required to be more stringent than the "external" emissions detailed in clause 5.1.6. Requirements for internal spurious emissions are necessary only for systems that are required to comply with compatibility requirements under clause 4.2 list items a, b and c. The levels of the spurious emissions from the transmitter, referenced to reference point B' of figure 1 of EN 32 217-1 [15] are specified in table 5. The level of spurious emission will be the total average level integrated over the bandwidth of the channel under consideration.

Within receive half band, digital into digital interference on the same local multi-channel branching/antenna system, for digital systems with compatibility requirements as specified in clause list item a. Within receive half band, digital into digital interference for digital systems without branching network (i.e. single transceivers with duplexer), for digital systems with compatibility requirements as specified in clause 4.2 list item b. Spurious emission frequency relative to channel assigned frequency Discrete (CW) spurious emissions within the same transmit half band All spurious signals within The receive half band Specification limit -6 dbm -9 dbm -7 dbm 6.4 Receiver characteristics 6.4.1 Input level range The input Receiver Signal Level (RSL) range, under flat fading condition, where the BER is kept lower than a specified level (typically 1-6 for availability purpose and, for higher modulation formats, 1-1 for errored seconds performance) depends on various parameters such as, but not limited to, frequency band, hop length and spectrum efficiency class. In principle, the highest is the range, the more flexible is the use of the equipment; however, high capacity systems with complex modulations (e.g. classes 5 and 6) suffer from one side of relatively higher RSL/BER thresholds and from the other side from more sensitivity to non-linear distortion caused by RX chain saturations. A unique standardized approach is not therefore advisable, nevertheless the necessary fade-margin shall be accommodated; the following "design objectives" are given for guidance only. The lower limit for the RSL threshold for a Bit Error Ratio (BER) 1-6 is specified in the relevant annex of EN 32 217-2-2 [16]. The upper limit for the RSL, where the same BER of 1-6, due to non-linear distortions, is not exceeded is assumed to be XX db above. In the same fashion, the upper limit for the RSL where a lower BER of 1 -y (typically 1-8 or 1-1 ) is not exceeded is assumed to be YY db above the relevant RSL threshold for that BER also specified in the relevant annex of EN 32 217-2-2 [16]. Indicative values for XX db and YY db are given in table 6.

NOTE 2: RSL higher than -22 dbm is not required. NOTE 3: RSL higher than -23 dbm is not required. NOTE 4: RSL higher than -24 dbm is not required. NOTE 5: For channel spacing > 28 MHz only. NOTE 6: For channel spacing 28 MHz only. NOTE 7: Higher value for systems with compatibility requirements under clause 4.2. NOTE 8: In case of two-carriers systems (D.8 and E.4 systems referred in annexes D and E, respectively), when carrying STM-4 or when carrying 4 STM-1, with each STM-1 mixed on both carriers, the test shall be made changing the RSL of both carrier simultaneously. For more details see clause G.3 in EN 32 217-2-2 [16]. These limits apply without interference and are referenced to point B (points B and C may coincide when simple duplexer is used) of figure 1 of EN 32 217-1 [15]. For equipment designed to operate only with ATPC as a fixed permanent feature the above maximum input levels are reduced by an amount up to the ATPC range. 6.4.2 Spurious emissions - internal For systems without the compatibility requirements of clause 4.2 there is no requirement. When equipment is required to share the same antenna with other equipment, the spurious emissions limits, referenced to point B, are specified in table 7. The required level will be the total average level integrated over the bandwidth of the channel under consideration. Table 7: Limits of spurious emissions-internal Controlling factor Spurious falling in the same receive half-band for systems with compatibility requirements of clause 4.2 list item a. Spurious falling in the same receive half-band for systems with compatibility requirements of clause 4.2 list item b. Specification limit -11 dbm -7 dbm NOTE: In addition, when compatibility with FDM systems on the same branching/antenna system is required, more stringent limits for CW lines (e.g. L.O. residual emission) might be necessary, ranging from -85 dbm to -125 dbm, according to the actual interfered baseband frequency of the analogue system and the possible additional decoupling due to local IPI of the antenna (conventionally assumed to be 4 db).

2 EN 32 217-2-1 V1.2.1 (27-6) 6.4.3 Image rejection The receiver image(s) rejection shall be as listed in table 8. Table 8: Receiver image rejection Controlling factor a) For any image frequency falling within the receive half band while using branching on different polarizations as defined under the compatibility requirements in clause 4.2 list item b. b) For systems not intended to fulfil any compatibility requirements in clause 4.2 list item a and/or 4.2 list item b. c) For any image frequency falling within the receive half band while using branching on same polarization, as defined in clause 4.2 list item a, or in the transmit half band on different polarization, as defined by the compatibility requirements in clause 4.2 list item b. d) For any image(s) frequency falling within transmit half band and using branching on same polarization, as defined by the compatibility requirements in clause 4.2 list item a. Image rejection 9 db Not Applicable 1 db 12 db Additional requirements, if any, may be found in the relevant annexes A through to E of the present document. 6.4.4 Innermost channel selectivity For systems, which are intended to comply with compatibility requirement under clause 4.2 list items a and b, to guarantee innermost TX/RX channel compatibility, the inner side of the innermost receiver shall be within the mask which is system and channel arrangement dependent and given in annex(es) to the present document. Since it is not considered feasible to make a practical measurement of this characteristic, the supplier shall give the design data of all filters implemented on this receiver. 6.5 System performance without diversity 6.5.1 Equipment Residual BER (RBER) The RBER level under simulated operating conditions without interference shall be guaranteed with a signal level at reference point B (or C) of the system block diagram of figure 1 of EN 32 217-1 [15], which is between 1 db and 35 db above the threshold level which gives BER 1-6 (as specified in clause 5.3.1); however an upper limit above -3 dbm is not required (see note 1). NOTE 1: Only for the 52 GHz and 55 GHz bands the value could be relaxed to -32 dbm. The requirement is intended between base-band ports at reference points X' and X shown in figure 1 of EN 32 217-1 [15]. As the measurement is made on the tributaries, the clause relative to one rate is also applicable to systems for n the same rate (e.g. requirement for 2 Mbit/s is applicable to n 2 Mbit/s). To guarantee a higher degree of service, see clause G.1, the network operator may require equipment to meet a RBER limit with the first adjacent channel interferer. In this case the RBER level under simulated operating conditions shall still be guaranteed with a signal level as specified above with an adjacent interference level set to represent a Carrier to Interference ratio (C/I) of: -4 db for all system classes 1 to 4. +7 db for class 5A systems (this figure assumes a minimum cross polar discrimination of 1 db for these systems). -3 db or -4 db for class 5B systems (see note 2). According to the supplier's declaration for class 6 systems.
