Electra Elite IPK II Document Revision 4C
Direct Inward Dialing (DID) 2 - 329
10-09-01 DTMF and Dial Tone Circuit Setup
If the system has DTMF DID trunks, be sure to reserve at least one circuit for analog trunk
DTMF reception (type 0 or 2). Each DTMF DID trunk must have an available receiver.
Use the following as a guide when allocating DTMF receivers:
In light traffic sites, allocate one DTMF receiver for every 10 devices that use them.
In heavy traffic sites, allocate one DTMF receiver for every five devices that use them.
14-05-01 Trunk Group – Trunk group Number
Put DID trunks in the same trunk group (other than group 1). If you have several types of DID
trunks, put each type in a separate trunk group.
15-07-01 Programmable Function Keys
Assign line or Call Appearance (CAP) Keys for DID trunks (Trunks: 1~200).
20-06-01 Class of Service for Extensions
Assign a Class of Service (1~15) to an extension.
20-09-01 Class of Service Options (Incoming Call Service) – Second Call for DID/DISA/DIL/E&M
Override
Turn Off (0) or On (1) an extension ability to receive a second call from a DID, DISA, DIL, or Tie
Line caller. (default: 1).
20-13-23 Class of Service Options (Supplementary Service) – Display the Reason for Transfer
Enable (1)/Disable (0) an extension ability to display the reason (Call Forward, Busy, No Answer
or DND) a VRS, DID, DISA, or ISDN call is being transferred to their extension. (default: 0).
21-01-02 System Options for Outgoing Calls – Intercom Interdigit Time
Set the time-out time for DID callers that do not dial. After this time, the DID call routes according
to Vacant Number Intercept programming. (default: 10).
22-01-06 System Options for Incoming Calls – DID Ring-No-Answer Time
Set the DID Ring No Answer (RNA) Intercept time (0~64800 seconds). In systems with RNA
Intercept, the DID call rings the destination extension for this time, and then rings Intercept Ring
Group. (default: 20).
22-02-01 Incoming Call Trunk Setup
For each Night Service Mode, enter service type 3 when the trunk should be a DID trunk.
22-04-01 Incoming Extension Ring Group Assignment
Assign extensions to Ring Groups. Calls ring the extensions according to programming in PRG
22-06.
22-09-01 DID Basic Data Setup – Expected Number of Digits
For each DID Translation Table (1~20), enter the number of digits the table expects to receive
from the CO (eight maximum). For example, for a table used with 3-digit DID service, enter 3.
22-09-02 DID Basic Data Setup – Received Vacant Number Operation
Selectively Enable (1)/Disable (0)) Vacant Number Intercept based on each DID Translation
Database (Program 22-11-01 and Program 22-11-02).
