REGISTRATION INTERFACE BRIDGED MULTIPLE TIP AND RING ARRANGEMENTS

Transcription

1 BELL SYSEM PCCES & Co Provisional SECON ssue, pril 1 1. GENEL 1.01 his section provides information on the standard wiring arrangements to be provided under the Federal Communications Commission FCC) egistration program. 1.0 f this section is reissued, the reasons for reissue will be contained in this paragraph. 1.0 he arrangements in this section use a 50-pin miniature ribbon connector female) to provide a bridged tip and ring connection of several telephone lines. Where Key elephone Systems KS) are involved, the and leads may also be supplied. he plug in the registered customer provided equipment CPE) must be a compatible 50-pin miniature ribbon plug male). 1.0 he lead to pin assignments differ for each arrangement, requiring care be taken that the connector be wired per Fig. through 5. Fig. 1 is provided as an aid in establishing the position and numbering of the contacts in the connector. EGSON NEFCE BDGED MULPLE P ND NG NGEMENS J1 X, JX, JX, ND JX 1.0 Unless otherwise specifically required by a particular wiring arrangement, access to the required leads can be at any access point. f installed in a large key system with color-keyed backboards, the auxiliary yellow) field should be used; otherwise, access at satellite closets, distribution boxes, connecting blocks, etc. 1.0 When necessary to access leads in COM KEY* installations, wire as follows: 1) COM KEY 1-ip and ring ahead of the line circuit can be obtained only at the 1 connecting block for the primary station. and will require use of a KS-15 adapter in the cabling loop. short length of connector cable must be plugged into the adapter and the raw end terminated on a -type connecting bloc1'-. he required leads are then accessed on the connecting block. Where,,, and are required behind the line circuit, the KS-15 adapter and short connector cable are again used but all leads are accessed on the -type connecting block. efer to Section for information on COM KEY n some of the arrangements only tip and ring are to be furnished to the CPE. Disposition of the other leads should be per local instructions. Note: Circuit incompatibility may occur involving the spare leads if a change of service is installed, ie, J1X, if installed originally, would not be compatible with a subsequent installation of JX. Whenever service is altered at a location involving registration USOC codes, verify that all appearances are properly wired. ) COM KEY 18-ip and ring ahead of the line circuit can be obtained at the incoming CO/PBX line terminations on block using 18B adapters. f,,, or are required behind the line circuit, they can be accessed per line at any of the line appearances of the station terminations on blocks,, or 5. gain use 18B adapters. For information on COM KEY 18, refer to Section ) COM KEY 1-ip and ring ahead of the line circuit can be accessed at the incoming line terminations on block using 18B adapters. and behind the line circuit and and NOCE Not for use or disclosure outside the Bell System except under written agreement Printed in U.S..

For information on COM KEY 1, refer to Section ) COM KEY 15-ip and ring ahead of the line circuit can be accessed on block of the lo0 or 101 connecting unit. and behind the line circuit and and are accessed per line on the station cutdown blocks of the connecting units. Use 18B adapters to provide termination. For information on COM KEY 15, refer to Section *rademark. DENFCON.01 USOC J1X: his arrangement provides a bridged connection of the tip and ring of a multiple number of CO or PBX trunks to the CPE. he connection is furnished through a fem ale ribbon connector, such as the KS-10 connector or equivalent, as part of an 5B connector cable. Up to 5 trunks or lines can be furnished Fig. ). Bridging to the tip and ring may be at various locations. ypical usage for J1X would be for connection of registered traffic data recording equipment furnished by the customer..0 USOC JX: Provides up to 1 CO/PBX circuits to the CPE where the tip and ring must be bridged ahead of the line circuit and lead control is required. Leads furnished to the CPE on a per line basis are,,, and using a KS-10 connector or equivalent Fig. ). ccess to leads will probably be at the KS to permit connecting tip and ring ahead of the line circuit and and behind line circuit. Primary use of arrangement will be where a number of ancillary devices, requiring lead control, are to be accessed by the CPE..0 USOC JX: his arrangement is similar to JX except the tip and ring, as well as and, are connected behind the line circuit. Up to 1 circuits are connected using the KS-10 connector or equivalent Fig. )..0 USOC JX: Provides the same,, and appearances plus,as a standard 5-line key telephone set to the CPE Fig. 5). he L and LG appearances are omitted. Connection to the CPE is through a KS-10 connector or equivalent. l connections are bridged behind the line circuit. Note: Some multibutton key sets are terminated in other than the standard wiring arrangement. When accessing the leads for this arrangement, care must be taken that the desired leads will appear on the connector as required.. MNENNCE.01 Maintenance of the wmng arrangements covered in this section is limited to: Verification of the telephone company wiring and equipment ssurance that the required leads are supplied in the interface used for CPE connection. No attempt should be made to test, modify, or repair customer-owned and maintained equipment..0 When in the judgment of repair personnel the trouble is located in the CPE, the epair Service Bureau should be notified so that proper Maintenance of Service Billing can be initiated as required and as outlined in the following: Section , Maintenance of Service Charge on Services With Customer-Provided Equipment CPE) Section , ariff and egistration Violation Notice Procedures.
