Time Slot Assignments<br />
For time slot assignments in the Dual T1 mode and in<br />
the Quad T1 mode, see Table 1.<br />
The <strong>Total</strong> <strong>Access</strong> <strong>1500</strong> platform can have multiple time<br />
slots in the T1 data stream assigned to each physical slot<br />
in the channel bank. The <strong>Total</strong> <strong>Access</strong> <strong>1500</strong> allows craft<br />
selectable time slots using the electronic provisioning<br />
interface. The system will automatically map DS0s in<br />
the T1 as determined by the LIU operational configuration<br />
or manual mapping is possible via the LIU<br />
configuration menu.<br />

Connections<br />
Two of the four 50-pin male amphenol connectors (P1<br />
through P4) on the rear of the <strong>Total</strong> <strong>Access</strong> <strong>1500</strong><br />
chassis provide the interconnections to each of the 24<br />
physical <strong>Access</strong> <strong>Module</strong> slots on the chassis. The 4W<br />
<strong>ETO</strong> uses P1 (T/R) and P2 (T1/R1) for the port 1<br />
connections. See Table 1 for wiring interconnection<br />
details.<br />
