Time Slot Assignments

For time slot assignments in the Dual T1 mode and in the Quad T1 mode, refer to Table 2.

The Total Access 1500 platform can have multiple time slots in the T1 data stream assigned to each physical slot in the channel bank. The Total Access 1500 allows craft selectable time slots using the electronic provisioning interface. The system will automatically map DS0s in the T1 as determined by the LIU operational configuration. Manual mapping is available via the LIU menu.

Connections

Four 50-pin male amphenol connectors on the rear of the Total Access 1500 chassis provide the interconnect wiring for each of the access module physical slots. The Dual 4-Wire TO requires P1 (T/R) and P2 (T1/ R1) for the odd ports of each access module, while P3 (T/R) and P4 (T1/R1) for the even ports. See Table 2 for wiring interconnect details.
