NEC 1091006 T1/PRI module
for DSX-80 & DSX-160 systems.

The T1/E1/PRI Line Card provides T1 advanced digital calling and gives the DSX-80/160 a maximum of 24 trunks in a single card slot.

T1 line types include Loop Start, Ground Start, Direct Inward Dialing (DID) Wink Start, Direct Inward Dialing (DID) Immediate Start, E&M Tie Line Wink Start, E&M Tie Line Immediate Start.

Tips to remember:

Normally you connect the T1/E1/PRI Card to a separately-purchased Channel Service Unit (CSU).

Use a standard straight-through CAT 5 cable to connect the T1/E1/PRI Card to the CSU. The CSU in turn connects to the telco smart jack.
