1. In 3101-01: Line Type (page 809), set the circuit type to match the connected service.
2. In 3101-03: DTMF Dialing (page 811) , indicate whether the line is DTMF ( 1 ) or Dial Pulse ( 0 ).
3. In 3103-03: Loop Length (page 815) for analog lines only, set this option to compensate for the telco cir-
cuits loop length.
- If the system is very close to the central office or behind a PBX, enter 1.
- For normal installations, enter 2.
1. Review the following timers:
- 160x-Feature Timers (page 669).
- 161x-COI (Analog Line) Timers (page 682).
- 163x-T1/E1 Timers (page 695).
- 164x-T1 Specific Timers (page 700).
- 165x-E1 Specific Timers (page 704).
1. If DTMF, check the settings in 1111-DTMF Setup (page 608).
2. If analog Dial Pulse, check the settings in:
- 1612-01: DP Break Timer (page 685).
- 1612-02: DP Make Timer (page 685).
