Procedure 116 Word 1: DS1/DMI/ISDN-PRI Trunk Assignments

For more information, see the chapter in this book entitled Port Types and Installation Compatibilities. Each analog trunk circuit pack provides four circuits that are administered by using procedure 150. Conversely, each DS1 provides 24 circuits (channels) that are administered by using procedure 116.

For traditional modules, each DS1/MFAT carrier will support a maximum of two DS1s, each occupying one slot and located in slots 5 and 18. When a DS1/DMI/ISDN interface (trunk applications) is located in slot 5, it functionally uses the six slots 0, 1, 2, 5, 6, and 7. When the interface is located in slot 18, it functionally uses the six slots 13, 14, 15, 18, 19, and 20. Figure 7- 44, Procedure 116 Word 1: DS1/DMI/ISDN-PRI Trunk Assignments, depicts this procedure.

The DS1 channels are assigned to slot and circuit locations according to the order in which the module processor scans the equipment carrier as shown in table 7-10,DS1/ISDN-PRI Administration

— Channel Versus Trunk Assignments.

When the traditional module DS1/MFAT carrier is configured with two DS1s, physical slots 3, 8, 16, and 21 are available for other applications. If only one DS1 is configured, then six additional slots are available for other applications.
