DSX-80/160 T1/E1/PRI Line Card
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. The available T1 line types include:
• Loop Start (DTMF and Dial Pulse)
• Ground Start (DTMF and Dial Pulse)
• Direct Inward Dialing (DID) Wink Start (DTMF and Dial Pulse)
• Direct Inward Dialing (DID) Immediate Start (DTMF and Dial Pulse)
• E&M Tie Line Wink Start (DTMF and Dial Pulse)
• E&M Tie Line Immediate Start (DTMF and Dial Pulse)
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.
• The T1/E1/PRI Card also provides 32E1 support. E1 is not used in North America.
• PRI is currently not available.
• You can install a T1/E1/PRI Card in any slot except slot 1.
DSX-80/160 16 Port CO Line (16COIU) Card with Caller ID
The 16COIU Card supports 16 analog loop start CO lines. The card has a Mode Switch (for taking the card
out of service), a status LED indicating proper card operation, and a port activity LED that indicates traffic
on the card. Each 16COIU Card also provides two power failure cut-through circuits. When commercial AC
power fails, the Card automatically cuts through two line circuits to two power failure single line telephones.
See System Configuration (page 19) for more.
Tips to remember:
• The 16COIU provides built-in Caller ID.
• You can install a 16COIU Card in any slot except for slot 1.
