Tie Lines
Description
Tie lines directly link a local DSX-80/160 telephone system with one or more remote DSX-80/160 systems.
The link is independent of the telco's switched network. When a local system user seizes a tie line, they hear
Intercom dial tone from the remote system. The user can then use many of the features normally available to
the remote system’s single line telephones, including:
❥ Dialing Intercom extensions in the remote system.
❥ Using the remote system's lines for outgoing calls.
❥ Accessing System Speed Dial bins in the remote system.
❥ Using the remote system’s Paging.
Tie Lines require a T1 PCB and Tie Line service from the telco.
Conditions
• None
Default Setting
• Disabled
Programming
1. Be sure your T1PCB is installed and connected, and that your telco is providing T1 tie line service.
2. In 3101-01: Line Type (page 809), enter the correct circuit type for each T1 tie line.
- 05 for E&M Wink Start
- 06 for E&M Immediate Start
3.
In
3101-03: DTMF Dialing (page 811)
, indicate whether the line is DTMF (
1
