21 1 Product overview 1-1 This chapter outlines the Spectrum Peripheral Module (SPM) product as implemented on the DMS-100 MMP switch for the ISN04 (TDM)software release. Ordering information PEC codes The PEC code for the Spectrum base frame assembly is NTLX91BA. The NTLX91BA frame can support two Spectrum Peripheral Modules. The PEC code for the STM-1 Resource Module is NTLX99BA (optical interface). Software optionality control The SPM is optional equipment. The relevant order codes are: STM Basic Software STM STM Network PRI STM ISUP and TUP protocols STM Optional Echo Cancellation Background What is Spectrum? Spectrum is a multi-application high-speed technology platform that provides a flexible, cost-effective and reliable architecture for future application development. Its hardware and software architecture allow it to interface easily with a wide variety of network traffic, and to perform signal-processing functions as well as handling routine call processing in conjunction with the DMS switch.

22 1-2 Product overview What is an SPM? The first application of Spectrum technology in the international market is an SPM providing a 1+1 redundant STM-1 trunking interface for the DMS-100 MMP switch. Note: Throughout this document, the Spectrum application SPM STM-1 trunking for the DMS-100 MMP switch is referred to as the SPM system. Scope of the SPM system in MMP releases The SPM features and functionality described in this document are implemented in the ISN04 (TDM) release. The source material used to produce this document contains ISN04 (TDM) information. Some chapters only highlight changes between previous MMP versions. References to the NTP documents, where detailed information is given, are added where necessary. SPM environment SPM in the network The SPM serves as a high-capacity feeder into the DMS-100 MMP switch, as shown in Figure 1-1. Figure 1-1 SPM position in the network SPM DXC DMS-100 MMP switch matrix (ENET) D S S T M 1 Optical interface (up to 1953 DS0s per module D D F S T M 1 S T M 1 to SDH ring The SPM system directly terminates an STM-1 carrier and feeds the individual DS0 traffic via DS512 from the carrier into the DMS-100 MMP switch. This configuration does not require external multiplexers to bring the carrier down to an E1 level, as is the case with PCM-30 Digital Trunk Controller (PDTC) trunk modules. Network synchronization The SPM system achieves SDH (Synchronous Digital Hierarchy) synchronization standards by loop timing to the SDH equipment to which it Standard April 2002

23 Product overview 1-3 is connected, for example, a digital cross-connect (DXC). This means that to maintain SDH synchronization standards, the SPM must always be connected to equipment capable of providing an SDH quality clock (DXC or equivalent). Back-to-back connection of two SPMs via STM-1 is a supported configuration. Note: All the clocking (message switch, SPMs, DXCs and so on) must be derived from the same source. SPM in the DMS-100 architecture Figure 1-2 shows the position of both the new SPM and an existing PDTC within the DMS-100 MMP architecture. Figure 1-2 SPM position within the DMS-100 MMP SuperNode CM IOC DMS-100 MMP DMS-BUS message switch ENET LPP PDTC SPM SPM E1 trunks STM-1 trunks Voice /Data Public Network In the DMS-100 MMP architecture, the SPM occupies a similar position to the existing PDTC peripheral. However, instead of terminating E1 carriers, the SPM terminates a single STM-1 optical carrier, with four times as many trunks as a single PDTC. The SPM can also perform echo cancellation without external equipment on its terminating trunks. DMS-100 MMP SPM STM-1 Trunking Service Implementation Guide ISN04 (TDM) and up

STM-1 TDM 1953 channels STM-1 Asynchronous interface SPM System 12K DS0 switch CEM DS512 interface DS channels E N E T DMS-100 MS CM 26 RM slots DSP-based Resource Modules Tone Receivers and Echo Cancellers The SPM system provides a redundant 1+1 STM-1 optical interface directly to the DMS-100 MMP switch. This interface supports asynchronous VC12 mapping. The incoming STM-1 TDM signal is broken into its composite DS0 time slots for routing to the internal 12K port timeswitch within the Common Equipment Module (CEM). The DS0 time slots can be used in the following ways: routed to any of the other resource modules on the SPM shelf for bit-stream processing sent directly to the ENET for call processing routing through the DS512 host links provided by the CEM card The DS512 links provide a full 2048 channels of bandwidth to the Enhanced NETwork (ENET), and allow for a full STM-1 payload (1953 channels) plus messaging between the SPM and the CM without a bandwidth bottleneck Standard April 2002

25 Product overview 1-5 Product features The SPM system has the following characteristics as an STM-1 trunking peripheral: coexists and interworks with DTCO and DTCOi supports ISUP and IUP (formerly BTUP) call processing in the DMS-100 MMP environment supports integrated echo cancellation with redundancy features supports an open interface to allow integrated echo canceller modules developed by licensed third parties supports current requirements for tone reception and COT testing supports ESTR capability for IN and other re-origination functionality Benefits The SPM system provides the following physical and operational benefits: reduction in central office physical plant reduced power consumption simplified switching/transmission boundary (optional) integrated echo cancellation integrated tone detection and tone generation use of existing OAM&P The following paragraphs give details of these benefits. Reduction in central office physical plant Figure 1-4 shows how the SPM system achieves floorspace savings by providing an STM-1 trunk interface directly to the DMS-100E switch.

This is the equivalent of 3.94 digital trunk controller (DTC) frames (3906/992). The SPM system also eliminates or significantly reduces the space required for MUX and external echo cancellers. This reduces the size of the wire centre and eliminates some cable congestion. An accurate view of the achievable physical benefits requires detailed analysis on a per office basis. However, a guideline average figure is a five times reduction in the peripheral footprint (one SPM, instead of four DTCO frames and an E1/STM-1 MUX frame). This would also lead to a five times reduction in the power consumption for peripheral equipment. Note: This power saving was evaluated in a comparative study of DTCO power measurements and SPM data. Nortel Networks Systems Engineering confirms the SPM model used as typical for UK customers: non-ecan and 2+1 DSP per SPM. Simplified switching/transmission boundary The SPM system simplifies the network and switch interface. It also provides the operating company with cost-of-ownership benefits over existing solutions Standard April 2002

27 Product overview 1-7 through the reduction of transmission equipment, and the elimination of copper interfaces and external echo cancellation equipment. Note: Although the SPM significantly reduces equipment in the wire centre, it is not intended that the SPM incorporates all transmission functions. The SPM should be viewed as a simplified interface between the DMS switch and SDH, incorporating some of the functional advantages of SDH equipment. Integrated echo cancellation The SPM system provides an optional echo cancellation facility, using integrated resource modules called Voice Signal Processors (VSP). The VSPs are plug-in modules and can be provisioned for 100% port coverage or pooled coverage (where only a percentage of the total number of speech time slots can use echo cancellation at one time). If less than 100% of the traffic requires echo cancellation, the SPM requires fewer VSP modules, thus providing a more economical deployment of the echo cancellation function. Nortel Networks also provides an interface specification to enable licensed third-party echo canceller vendors to design and supply integrated echo cancellers for the SPM system. These units will be fully compatible with all SPM physical, logical, and software support systems. Integrated tone detection and tone generation The SPM system provides integrated tone detection and tone generation using the Digital Signal Processor Resource Module (DSP RM). The DSP RM is a plug-in module and can be provisioned for 100% trunk coverage or pooled coverage. Its functionality is equivalent to the Special Tone Receiver (STR) and Universal Tone Receiver (UTR) used in the XPM peripherals. It can also be used for both short and long duration tone detection. Use of existing OAM&P Because the SPM system is an integral subsystem of the DMS-100 MMP switch, it uses the existing switch-based operations, administration, maintenance and provisioning (OAM&P) facilities, via the Maintenance and Administration Position (MAP). This method of network management requires minimal retraining of operating company personnel. DMS-100 MMP SPM STM-1 Trunking Service Implementation Guide ISN04 (TDM) and up

29 2 Development summary 2-1 This chapter outlines the hardware and software development for the SPM STM-1 trunking application. Functionality deliverables The ISN04 (TDM) product release includes changes made at MMP16. The numbers in brackets represent the feature number associated with the functionality change. ISN04 (TDM) At ISN04 (TDM), SPM supports the following STM-1 functionality: STM-1 K1 / K2 Byte Support ( ) Protocol description This feature enables Multiplex Section Protection (MSP) switching of a signal. MSP is a mechanism that protects a number of VC-4 services by using an additional hardware and fiber installation. MSP provides a capability such that, in the event of the failure of the Working section of an STM-1 resource module, the signal may be made available via the Protection section. For STM-1 carriers on a Spectrum Peripheral Module (SPM), this feature provides the following modes of switching: 1+1 unidirectional protection (revertive mode) 1+1 bidirectional protection - compatible with 1:n (revertive mode) 1+1 bidirectional protection - compatible with 1:n (non-revertive mode) 1+1 bidirectional protection - optimized for 1+1 network For unidirectional switching, the switching is independent of the remote node operation and switching is complete when the traffic DMS-100 SPM STM-1 Trunking Service Implementation Guide ISN04 (TDM) and up

30 2-2 Development summary in the failed direction of the local node is switched to the other section irrespective of whether the remote end has switched or not. Note: Unidirectional protocol was supported prior to this feature being implemented. Bidirectional switching requires the MSP functions at both ends of the MSP link to be able to communicate with each other and thereby to co-ordinate the switch. This feature provides the necessary bit-orientated protocol, using the K1 and K2 bytes, to perform this activity. If one node is configured for unidirectional switching and the other node is configured for bidirectional switching, the node with bidirectional switching will never switch, as the MSP protocol will fail. In revertive mode: if an MSP switch occurs, the traffic is switched from the Working Section to the Protection Section. When the Working Section has been repaired, the traffic will automatically revert back to the Working Section. Interface The operator has the ability to select one of the above modes of switching by changing data schema table configuration. This feature allows the STM1 interface of the SPM to be interconnected with any other vendor's equipment following ITU-T G.841. This feature introduces the following new commands: Lockout If applied to optimized protocols, it freezes the position of the section selector. If applied to non-optimized protocols, it prevents switching to the Protection section. Exercise This command provides the ability to test the bidirectional mode - it only applies when there is no failure. Clear This command clears all other switching commands. This feature provides eight new alarms for monitoring the system. MSP alarms are raised to indicate a restraint, on the Multiplex Standard April 2002

31 Development summary 2-3 Protection section mechanism, to recover from faults occurring on STM1M carriers. The alarms will be raised either for a: User action (the issue of a lockout, force or manual command), or Fault in communication with the distant equipment (that is, a different configuration at each end of the link or a fault occurring during sparing). STM-1 France VN4 / VN6 ( ) This feature provides support of VN4 and VN6 PRI trunks on the STM-1 interface of the Spectrum Peripheral Module (SPM). Functionality is equivalent to that provided on the PCM-30 Digital Trunk Controller (PDTC) for network mode on the DMS-100E. The functionality is defined in NIS A215-1, ETSI PRI (T) Specification, DMS-MMP Implementation of ETSI ISDN Primary Rate Interface at the T Reference Point; 21 January All VN4 and VN6 supplementary services are supported on the STM-1 interface on the SPM by activities: and STM-1 Turkish ISUP V2 ( ) This feature adds the Turkish ISUP V1 and Turkish ISUP V2 protocols to the Spectrum Peripheral Module (SPM) STM-1 interface, thereby allowing network operators to connect to the Turkish Telecom network using a direct STM-1 interface. It introduces functionality to enable the DMS-100 MMP switch to support the Turkish protocol variants Turkish ISUP V1 and Turkish ISUP V2 using the SPM STM-1 peripheral. Turkish ISUP V1 and Turkish ISUP V2 are variants of the ETSI ISUP V1 and ETSI ISUP V2 protocols. Functionality is equivalent to that provided on the PCM-30 Digital Trunk Controller (PDTC) for network mode. The architecture in the SPM is the same as in XPM (Extended Peripheral Module). STM-1 Israel ISUP ( ) This feature adds the Israel Civilian ISUP V2 and Israel Defense ISUP V2 protocols to the Spectrum Peripheral Module (SPM) STM-1 interface, thereby allowing network operators to connect to the Israeli Telecom network using a direct STM-1 interface. It introduces functionality to enable the DMS-100 MMP switch to support the Israeli protocol variants Israel Civilian ISUP V2 and Israel Defense ISUP V2 using the SPM STM-1 peripheral. Israel Civilian ISUP V2 and Israel Defense ISUP V2 are variants of the ETSI ISUP V2 protocol. Functionality is equivalent to that provided on the PCM-30 Digital Trunk Controller (PDTC) for network mode. DMS-100 SPM STM-1 Trunking Service Implementation Guide ISN04 (TDM) and up

32 2-4 Development summary This implementation provides full backwards charging support. STM-1 French ISUP - SPIROU ( ) This feature adds the SPIROU V3 ISUP protocol to the Spectrum Peripheral Module (SPM) STM-1 interface, thereby allowing network operators to connect to the French Telecom network using a direct STM-1 interface. It introduces functionality to enable the DMS-100 MMP switch to support the French protocol variant SPIROU V3 using the SPM STM-1 peripheral. This implementation provides full backwards charging support, providing an ability to generate charge messages. SPIROU V3 enables network operators to interface on all French Telecom interconnection points (both transit and local). Note: The functionality currently available on the DMS-100 for SPIROU ISUP remains unchanged. At MMP16, SPM supports the following functionality: STM-1 SPECCONN Completion ( ) This feature provides the ability to specify a 64 Kbit/s clear path nailed-up connection between two P-side endpoints (ports) where one or both endpoints reside on a Spectrum Peripheral Module (SPM) equipped with the 155 Mbits/s STM-1 interface. Table SPECCONN The nailed-up connection is provisioned by datafill in the SPECCONN table in the Computing Module (CM). The datafill consists of two endpoints, a connection type, and a connection status. SPECCONN is modified to allow SPM to be accepted as a valid peripheral type for D30 endpoint types Standard April 2002

33 Development summary 2-5 CI command QSCONN The QSCONN command is used to query the state of individual connection segments. Therefore this command supports queries where SPM is specified as an endpoint. Note: Digital Test Access (DTA) or ISDN Line Card (ISLC) functionality, currently supported for XPM, will not be supported for the SPM. Logs Five existing logs (PM231, PM232, PM233, PM234, PM236) are modified so that entries can be made into these logs for special connections. ISUP Australia Interconnect ISUP ( ) This feature introduces functionality to enable the DMS-100 switch to support Australia Interconnect ISUP (Ie-ISUP) using the Spectrum Peripheral Module STM-1 peripheral. This feature adds the Australia Interconnect ISUP protocol to the SPM STM-1 interface, thereby allowing network operators to connect to the Australian Telecom network using a direct STM-1 interface. This activity provides the functionality required within the SPM to support the Australian Interconnect ETSI ISUP V2 protocol (referred to as AustraliaIC ISUP) using the STM-1 interface. Australia Backbone ISUP ( ) This feature is split between two other functionality features, namely AU2371 and AU2371 (Serving Carrier ID) This feature allows the name of the carrier switch name to appear in AMA. It provides a means of associating a serving carrier against lines and trunks on a DMS100. The serving carrier is defined as the carrier providing the service. The serving carrier information is used for billing purposes, so that the originating and terminating party lines determine the billing rate (MWI over ETSI ISUP and DN Padding for SMDI-Preparation) The Message Waiting Indication (MWI) supplementary service enables the telecommunications network, upon the request of a voice mail centre, to indicate to the subscriber that there is at least one message to be retrieved. This occurs when an agent, provisioned for the MWI service, receives mail on his mailbox at DMS-100 SPM STM-1 Trunking Service Implementation Guide ISN04 (TDM) and up

34 2-6 Development summary the Voice Message System (VMS). A request is made to MWI to indicate to the subscriber that mail is pending. The subscriber is informed instantly and whenever the receiver is in off-hook mode. When the subscriber attempts a call, the MWI supplementary service is activated and an indication of a message waiting is sent to the subscriber. The subscriber now accesses the voice mail centre and the message is delivered. When the subscriber has retrieved all of their messages by dialling into the VMS, the MWI is deactivated. This feature extends existing MWI functionality (IBN lines on V5.2, CAS MUX lines, EBS sets and SMDI) to the following agents:etsibri,etsipriandetsitcap. A new office parameter, DEFAULT_MWI_XLA_ENTRY within OFCENG, provides a default entry point to translations for ETSI MWI requests. For ETSI MWI, message waiting indication requests are given universal translations to determine the receiving user of the request. Voice mail systems are connected to MMP DMS100 via an SMDI (Simplified Message Desk Interface) link. Padding is necessary for directory numbers (DNs) which are not either 7 or 10 digits in length. A voice mail subscriber may only access his mailbox if the subscriber s DN is padded correctly for non-7 or 10 digit DNs. This feature enables the MMP DMS100 product to configure SMDI with the correct padding digit. France SSUTR2 ( ) This feature introduces functionality to enable the DMS-100 switch to support SSUTR2 using the Spectrum Peripheral Module STM-1 peripheral. PRI STM-1 ETSI PRI ( ) This feature provides support for ETSI PRI trunks on the STM-1 interface of the Spectrum Peripheral Module (SPM). Functionality is equivalent to that provided on the PCM-30 Digital Trunk Controller (PDTC) for network mode. The functionality is defined in NIS A215-1, ETSI PRI (T) Specification, DMS_MMP Implementation of ETSI ISDN Primary Rate Interface at the T Reference Point;21 January Standard April 2002

35 Development summary 2-7 This feature supports the following Supplementary Services: Call Completion to Busy Subscriber (CCBS) Calling Line Identification Presentation (CLIP) Calling Line Identification Restriction (CLIR) Closed User Group (CUG) COnnected Line identification Presentation (COLP) COnnected Line identification Restriction (COLR) Direct Dialling In (DDI) Diversion - Partial Reroute (PPR) section only Explicit Call Transfer (ECT) Malicious Call IDentification (MCID) Subaddressing (SUB) User-to-User Signalling (UUS) - Service 1 STM-1 PRI - AOC and Metering ( ) This feature supports the Advice of Charge (AOC) services that are used to collect and transmit real-time charging information to an originating subscriber for the calls they are making. Charging services can be collected: On a regular basis during a call (AOC-D service) or At the end of a call (AOC-E service) or Both This feature implements the Spectrum Peripheral Module (SPM) portion of the functionality required to provide both AOC-D and APC-E services on the SPM platform for the ETSI PRI protocol. STM-1 PRI Digital Test Access ( ) This feature enhances digital monitoring of STM-1 Common Channel Signalling (CCS7) links by providing the capability to monitor PCM-30 Primary Rate Interface (PRI) channels on an SPM equipped with STM-1 RM and CEM cards, and a Data Link Controller (DLC). The CONNECT command has been enhanced to support the SPM and allow the monitoring equipment to connect to the PRI D-channel. The CONNECT command also allows Digital Test Access (DTA) connections to be verified and released. DMS-100 SPM STM-1 Trunking Service Implementation Guide ISN04 (TDM) and up

36 2-8 Development summary T&C SPM Hardcoded Tones - Australia, Switzerland, Portugal, New Zealand, Ireland ( ) This feature supports the implementation of tonesets for the following markets: Australia New Zealand Portugal Ireland Switzerland The tonesets are selectable through datafill provisioning of six corresponding tone synthesizer resource types in table MNCKTPAK. Only one type of tone synthesizer resource can be datafilled on all Resource Modules of a given Spectrum Peripheral Module (SPM), that is, only one tone synthesizer resource type is allowed per node. MMP15 In MMP15, SPM supports: Belgian ISUP, Italian ISUP, Spanish ISUP and Brazilian ISUP as well as Italian, Spanish and Brazilian tones. Belgian tones were available with MMP13. Whilst providing enhancements to the ECAN capability that was delivered with MMP13, the MMP15 release also supports KLM numbering and German Network Protection. The extra SPM functions available in the MMP14 and 15 release are as follows: ETSI ISUP signaling and variants: Italian ISUP ( ) Supports: ISUP redirection information on call-forward, emergency calls, and Nuisance Caller Identification (NCI) without trunk hold. Spanish ISUP ( ) The Spanish ISUP is implemented as a variant of the ETSI ISUP V1 protocol. It is dependent on the ETSI ISUP implemented within SPM. A message interface has to be created specifically for Spanish ISUPs due to the fact that it handles messages in a different way to the base ETSI ISUP V Standard April 2002

37 Development summary 2-9 Belgian ISUP ( ) Supports: ISUP redirection information on call-forward, emergency calls, and Nuisance Caller Identification (NCI) without trunk hold. Brazilian ISUP ( ) Supports: The following bearer services: Speech, 3.1 khz audio, and 64 kbits/s unrestricted. Allows: End-users in Brazil to remotely access the DMS-MMP and its services, and service providers to connect to Telebras. The Brazilian ISUP is implemented as a variant of the ETSI ISUP V1 protocol. It is dependent on the ETSI ISUP implemented within SPM. SPM STM-1 Carrier Maintenance ( ) Supports: Carrier maintenance for a new STM-1 high speed access interface, primarily for the international market. KLM numbering ( ) Supports: KLM numbering within the VC4P payload of VC12P and E1P carriers. SETCARR, GETHIST and LISTHIST commands support the use of payload positions using KLM co-ordinates. STM-1 Italian and Spanish tones ( ) International tonesets for Italy, Spain and Brazil are implemented to complement those in Germany and the UK. Downloadable tonesets that rely on matching data in the XPM files are not compatible. These tonesets require reformatting to the newer versions before they can be supported on SPM. IUP and ECAN enhancements ( ) Provides provisioning and call processing support to control integrated Echo Canceller (ECAN) on SPM. Echo cancellation is now available for BTUP trunks. This feature provides similar functionality to the XPM platform. The implementation is compatible with the operation of XPM-based echo cancellers and with interworking between SPMs and XPMs on the same switch. Brazilian ISUP for Succession MG4000 ( ) Provides the toneset for the Brazilian Market. A programmable tone synthesizer, BRATONE, is used to generate a variety of call progress, signalling and sequence tones. BRATONE synthesizes the tones from fundamental parameters (frequency, amplitude and cadence) instead of wavetables stored in memory. Therefore new types of tones can be produced by downloading new parameter values. Therefore new wavetables and hardware updates are not required.

38 2-10 Development summary Digital Test Access ( ) Provides digital monitoring of STM-1 Common Channel Signalling (CCS7) links. It also provides the ability to monitor analogue and digital voice trunks. There are four types of monitoring that refer to accessing a trunk that has a trunk-to-trunk call connected. Note: This is a test only feature. German Network Protection ( and ) This is a regulatory feature required by the German market. It provides Priority Class of Service (PCoS), which is used to prioritize specific types of calls. If the feature is activated, then under certain predefined conditions only, those calls marked as priority are passed on through the network to the SPM. Hardware development The Spectrum technology platform represents an entirely new set of mechanical shelving and circuit pack designs. All circuit packs share common features and plug into a double-height shelf with a single backplane designed to fit an ANSI rack. (SPM configured in an ETSI rack is not currently available.) The design is compatible with Model B lineups. Product structure The Spectrum product structure is designed to support multiple Spectrum technology applications by building applications on the base frame assembly, NTLX91BA. This base assembly contains all the components, other than the circuit packs, that are common to any Spectrum-based application. The circuit packs are documented in the Modular Structure (MS) document, according to Modular Documentation System (MDS) rules. This documentation method assumes that all Spectrum technology customers use the current SPM-designed backpanel and frame mechanicals.

44 3-2 Functional overview Interface to two SPM common equipment modules (CEM; active and inactive) via nine SPM serial links to each CEM Multiplex Section Protection (MSP) switching of a signal ( ISN04 (TDM)) - see section on Protection Switching for a detailed description. Improves MSP switching by providing: STM unidirectional non-revertive multiplexer section protection STM unidirectional protection (revertive mode) STM bidirectional protection - compatible with 1:n (revertive mode) STM bidirectional protection - compatible with 1:n (non-revertive mode) STM bidirectional protection - optimized for 1+1 network Commands (CLEAR, EXERCISE and LOCKOUT) to control the MSP switching of a signal Alarms for monitoring the MSP switching of a signal SPECCONN Completion ( MMP16) This feature provides the ability to specify a 64 Kbit/s clear path nailed-up connection between two P-side endpoints (ports) where one or both endpoints reside on a Spectrum Peripheral Module (SPM) equipped with the 155 Mbits/s STM-1 interface. The connection has the following attributes: The connection is permanent. Once made, it can be removed only through deliberate action by operating company personnel. The connection is a dedicated 64 Kbit/s data communication path. It can carry voice and/or signalling information from the P-side on an extended peripheral module (XPM) to a P-side on the same or a Standard April 2002

45 Functional overview 3-3 different XPM. The connection can also carry four 16 Kbit/s time division multiplexed (TDM) D-channels. The connection is defined and controlled by the CM. The connections use non-channelized access CCS7 signalling. The nailed-up connection is provisioned by datafill in the SPECCONN table in the Computing Module (CM). The QSCONN command is used to query the state of individual connection segments. Therefore this command supports queries where SPM is specified as an endpoint. Five logs (PM231, PM232, PM233, PM234, PM236) are used so that entries can be made into these logs for special connections residing on an SPM. Protection switching A particular carrier level may be defined as a protection group, where one carrier is the active carrier and the other carrier is inactive. If a problem occurs on the active carrier, traffic can then be switched to the inactive carrier. This is known as a protection switch. For the SPM system, carrier protection operates at the multiplexer level and thus carrier protection switching is applicable only to multiplexor section (STM1M) carriers. The initial implementation of the STM-1 interface (MMP13) provided uni-directional non-revertive switching only. At ISN04 (TDM), feature (STM-1 K1 / K2 Byte Support) added significant functionality to protection switching. From ISN04 (TDM) the following additional protection mode schemes were provided: 1+1 unidirectional protection (revertive mode) 1+1 bidirectional protection - compatible with 1:n (revertive mode) 1+1 bidirectional protection - compatible with 1:n (non-revertive mode) 1+1 bidirectional protection - optimized for 1+1 network For unidirectional switching, the decision to perform a protection switch is made locally and independently of the remote node. Switching is complete when the traffic received by the SPM is switched to the other section irrespective of whether the remote end has switched or not. Signaling is provided over the K1, K2 bytes to inform the remote node of the SPM s actions. Bidirectional switching requires the MSP functions at both ends of the MSP link to be able to communicate with each other and thereby to co-ordinate the switch. This feature provides the necessary bit-orientated protocol, using the K1 and K2 bytes, to perform this activity. Both the local and remote nodes must be configured to use the same bidirectional switching scheme, otherwise switching will not perform correctly.
