AT&T DS1/DMi/ISDN-PRI DS1 Channel Slot/Circuit, 14ADMINISTRATION Options and Requirements System

7-14ADMINISTRATION OPTIONS AND REQUIREMENTS — SYSTEM 85

Also, the facility cannot be used as a synchronization reference.

When a DS1 is administered for lines (OPS), it provides 24 channels that terminate in a remote D4-channel bank, CDM, or their equivalent.

Each analog line circuit pack provides eight circuits. Therefore, one DS1/OPS functionally replaces three analog circuit packs. Each DS1 or multifunction analog terminal (MFAT) carrier will support a maximum of four DS1s (OPS applications). These may be located in slots 0, 5, 13, and 18.

The DS1 channels are assigned to slot and circuit locations according to the order in which the module processor scans the equipment carrier. Table 7-1, DS1 Administration — Channel Versus Line Assignments, lists the equipment location versus DS1 channel assignments for DS1/OPS.

Analog equipment location assignments are administered by procedure 000, word 1, with field 8 translated a 2. The DS1/OPS channels are translated to equipment locations (individual extensions) with procedure 000, word 1, with field 8 translated 9, rather than with procedure 116 that was used for trunks.

5Selects the DS1 used to provide 64K-bps data with DMI-MOS or ISDN-PRI trunk facilities. When encode 5 is administered, procedure 262 is automatically translated with standard default options. These default options should (later) be checked for consistency with the distant end; refer to procedure 262.
