1. Be sure your T1PCB is installed and connected, and that your telco is providing T1 service.
2. In 3101-01: Line Type (page 809), enter the correct circuit type for each T1 line.
• 00 for uninstalled
• 01 for Loop start
• 02 for Ground Start
• 03 for DID Wink Start
• 04 for DID Immediate Start
• 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) or Dial Pulse (0).
1. Review the following timers for compatibility with your connected T1 service.
- 1631-Incoming (page 695)
