T1 Lines

T1 Lines

Description

In DSX-80/160, provides for connection to advanced digital lines and simplifies installation.

T1 lines require a unique T1 PCB (P/N 80061) and give the system a maximum of 24 lines in a single PCB slot. The available T1 line types include:

❥Loop Start (DTMF and Dial Pulse)

❥Ground Start (DTMF and Dial Pulse)

❥Direct Inward Dial (DID) Wink Start (DTMF and Dial Pulse)

❥Direct Inward Dial (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)

T1 gives the system the advantages of advanced digital calling as well as conserving PCB slots. For exam- ple, you can set up a system with 12 loop start lines, six tie lines, and six DID lines and use only a single PCB slot. Additionally, the T1 PCB has its own on-board processor and DSP so it minimally impacts other system resources.

Note: Although the T1 PCB can connect directly to the telco’s T1 smart jack, your telco may require that you purchase and install a separate Channel Service Unit (CSU). This unit installs between the smart jack and the T1 PCB.

ANI/DNIS Support

The system is compatible with telco's T1 Automatic Number Identification (ANI) and Dialed Number Infor- mation Service (DNIS) services. ANI/DNIS services can be provided on T1 loop start, ground start, and DID lines (but not E&M). ANI/DNIS Compatibility provides:

❥Selectable Receive Format

You can set up the system for compatibility with any combination of ANI, DNIS and Dialed Number (Address) data provided by the telco.

❥Flexible Routing for DID Lines

For DID lines, the system can route the incoming call based on the received DNIS data and the entries stored in the DID Translation Table. See Direct Inward Dialing (page 99) for more.

❥Caller ID

The system can use the received ANI data to display the caller’s number on the called extension’s dis- play. The ANI data can be up to 10 digits long.

FSK Caller ID

The T1 PCB can also receive FSK-based Caller ID (if provided by the telco), the same as the COIU (analog) line cards. To receive this type of Caller ID, you must enable DSP Caller ID for the T1 line circuits in pro- gramming. See the Programming below for more.

E1 Lines

The T1 PCB also supports E1, which provides 30 digital line circuits. E1 lines are not available in North America.
