Programming Basics

1. Set the circuit type for each DID line.

  1. Be sure your T1/PRI PCB is installed and connected and that your telco is providing T1 DID service.
  2. 3101-01: Line Type [Lines: Config: Setup: Type (3101): Type]
    Use this option to enter the correct circuit type for each DID line

  3. 3101-03: DTMF Dialing [Lines: Config: Setup: Type (3101): DTMF Dialing]
    Use this option to indicate whether the line is DTMF (1) or Dial Pulse (0).
    Option Description
    No (0) Dial Pulse.
    Yes (1) [Default] DTMF.
  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 [Lines: Config: Setup: Type (3101): DTMF Dialing].

2. Set up DID Translation.

  1. 3301-01: Number of DID Digits [Lines: DID: Setup: Configuration (3301): Number of DID Digits]
    Specify the number of incoming DID digits you expect to receive from the telco for each DID call.
    This is the number of received DID digits that the system feeds into the DID Translation Table in the next step.
    Option Description
    1-8 DID digits received. [Default] = 3.
  2. 3302-01: Incoming DID Digits [Lines: DID: Setup: Translations (3301): Incoming Digits]
    This is the first step in building a DID Translation Table. Specify the digits you expect to receive from the telco.
    The default entry of *** means the system accepts any three digits.
    Option Description
    Digits 1-8 total digits using 0-9.
    * Wild card representing any digit. [Default] = *** for entry 001. All other table entries are blank.
  3. 3302-01: Day Translation Destination [Lines: DID: Setup: Translations (3301): Day Translation]
    For the incoming digits received, use this option to define the day destination for the call.
    The default entry of 3** means the system routes to an extension in the day mode according to the last two digits dialed.
    Option Description
    Digits 1-8 total digits using 0-9.
    * Wild card representing any digit. [Default] = 3** for entry 001. All other table entries are blank.
  4. 3302-01: Night Translation Destination [Lines: DID: Setup: Translations (3301): Night Translation]
    For the incoming digits received, use this option to define the night destination for the call.
    The default entry of 3** means the system routes to an extension in the night mode according to the last two digits dialed.
    Option Description
    Digits 1-8 total digits using 0-9.
    * Wild card representing any digit. [Default] = 3** for entry 001. All other table entries are blank.

3. Allow the extension to receive DID calls.

  1. 1401-08: Receive DID Calls [System: Class of Service: Features: Features (1401): Allow DID Calls]
    If you enable this option, the extension can receive DID calls. If disabled, DID calls won't go through.
    Option Description
    No (0) Disabled.
    Yes (1) [Default] Enabled.
  2. 2102-01: Class of Service [Stations: Config: Setup: Access (2102): Class of Service]
