Cabling D/120JCT-LS PCI Linecards to the Telephone System
Once the D/120JCT-LS linecards are installed in the platform, you can cable the platform to the
telephone system. OneBox assigns port numbers in ascending order based on the linecard
identification number. For example, a D/120JCT-LS linecard to which you assigned the linecard
ID 1 is assigned line numbers 1
–12; a D/120JCT-LS linecard to which you assigned the linecard
ID 2 is assigned line numbers 13-24 (Figure 8).
Refer to the topic, ―
‖ for information on assigning the linecard ID. Keep this line number
scheme in mind when connecting each D/120JCT-LS linecard to the telephone system.

NOTE
Pins 1 and 6 are not used in the United States and should not be connected to the
telephone system. The connectors on the rear bracket of the D/120JCT-LS linecard accept
linecords equipped with standard RJ-14 connectors.
Depending on the type of telephony interface provided for connectivity to the telephone network,
you may require linecord adaptors to connect the Call Server platform to the telephone system.
If linecord adaptors are required but not included with the linecards, contact your Customer
Service Representative.
