Basic Programming
1. Be sure your T1 PCB is installed and connected and that your telco is providing T1 DID service.
2. In 3101-01: Line Type (page 809), enter the correct circuit type for each DID line:
- 03 for DID Wink Start
- 04 for DID Immediate Start
3. In 3101-03: DTMF Dialing (page 811), indicate whether the line is DTMF (1) or Dial Pulse (0).
4. If your telco provides DID service using E&M Wink Start DTMF signaling, choose circuit type 03 (DID
Wink Start) and enable 3101-03: DTMF Dialing.
1. In 3301-01: Number of DID Digits (page 834), specify the number of incoming DID digits expected
from the connected DID service.
- By default, the system expects to receive three DID digits from the connected service.
1. Use the following programs to set up DID Translation:
- 3302-01: Incoming DID Digits (page 836)
(The default entry of *** means the system accepts any three digits.)
- 3302-01: Day Translation Destination (page 836)
(The default entry of 3** means the system routes to an extension in the day mode according to the
last two digits dialed.)
- 3302-01: Night Translation Destination (page 836)
(The default entry of 3** means the system routes to an extension in the night mode according to
the last two digits dialed.)
1. In 2102-01: Class of Service (page 724), check the extension’s Class of Service level.
2. If yes, in 1401-08: Receive DID Calls (page 630) enter Yes.
3. If no, in 1401-08: Receive DID Calls (page 630) enter No.
1. If yes:
- In 3121-01: Caller ID Type (page 825), enter 3 to enable ANI-based Caller ID for the line.
- In 3121-02: ANI/DNIS Format (page 825), specify the type of ANI/DNIS data received from the
telco:
- 0 for No ANI/DNIS data
- 1 for ANI
- 2 for *ANI*
- 3 for *DNIS*
- 4 for *ANI*DNIS*
- In 3121-03: ANI/DNIS Delimiter (page 826), indicate the type of ANI delimiter provided by the
telco (for options 2-4 above only). The delimiter can be any character 0-9, #, or *. Normally, the
delimiter is *.
1. Set the circuit type for each DID line.
2. Specify the number of incoming DID digits you expect to receive from the telco.
3. Set up the DID Translation Table.
4. Should the extension be allowed to receive DID calls?
5. Do the T1 lines provide ANI/DNIS services?
