ADMINISTRATION OPTIONS AND REQUIREMENTS — GENERIC 1 7-115

GENERIC 1

Generic 1 has the same DS1 facility considerations (such as framing, signaling, line coding format) as System 75. It also requires the additional clock circuit pack for synchronization. The main significant difference between a System 75 and Generic 1 is support of the TN767 circuit pack for both DS1/DMI and ISDN-PRI.

Depending on whether a Generic 1 provides private network ISDN service or public network ISDN services, whether the switch functions as an endpoint or as a tandem node, will determine whether other features or screens should be administered with ISDN-PRI. Primarily, these other features and screens include:

1.AAR/ARS

2.Ten- to seven-digit conversion

3.DCS/uniform dialing plan

4.Call-by-Call Service Selection

5.SID prefix assignments

6.Routing patterns

The SYSTEM-PARAMETERSCUSTOMER-OPTIONSscreen displays these and other optional features. New switches should come with the appropriate optional features already enabled. Switch upgrades (depending on the specifics) may require that the CSSO alter the SYSTEM-PARAMETERS CUSTOMER-

OPTIONS screen.

Service/Facility Options

The DS1 CIRCUIT PACK screen is used to define characteristics of the DS1 facility. This screen requires that the circuit pack (TN722_/TN767) have been previously assigned to an equipment location (carrier and dot) by the CIRCUIT PACK ADMINISTRATION screen. For ISDN-PRI applications, the screen has minor differences. Therefore, two screens are depicted. The first is for DS1/DMI-BOS and the second is for ISDN-PRI.

Screens are shown with default or recommended field options. Figures 7-60,DS1 Circuit Pack Screen, Common-Channel Signaling, and 7-61, DS1 Circuit Pack Screen, ISDN-PRI Signaling, depict this procedure.
