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.
