The Digital DID Trunk Circuit Descriptors form is used to assign signaling and timing parameters to groups of DS1 DID trunk circuits using channel associated signaling (CAS).
Use this form when performing the following tasks:
Note: The operating characteristics for all trunks are defined by the respective trunk circuit descriptor form. There are 32 trunk circuit descriptor numbers available. These must be shared between all trunks in the system. As well, each circuit descriptor number assigned must be unique. MITEL recommends that the circuit descriptor numbers be allocated to each type of trunk in blocks. For example, CO trunks may be allocated circuit descriptor numbered 1 through 4, E&M trunks numbered 5 through 12, DS1 DID trunks numbered 13 through 21, and so on.

Default Value |
|
Number |
Enter a number from 1 to 32 to uniquely identify each entry. |
Blank |
|
Ignore Far End Disconnect |
Select "Yes" or "No" to indicate whether the trunks are to ignore or respond to a far-end disconnect signal. |
No |
|
Release Acknowledge Timer |
Enter the amount of time the system will wait for a release acknowledgement from the far-end. Allowed values are 40 - 9000 units (200 ms - 450 sec), each unit being equal to 50 ms. |
(80 UNITS) 4s |
|
Address Signaling |
Select the appropriate value to indicate the type of signaling used.
|
DTMF |
|
Incoming Start Type |
Select the appropriate value to indicate whether the trunk is immediate, delay dial, or wink start on incoming calls. Applies only to DS1 DID trunks. |
Wink |

Flash Timer |
Enter a value between "200" and "700" milliseconds in increments of 50 milliseconds. This timer specifies the duration of the single trunk flash or each of the flashes for a double trunk flash. For a double flash, the time between flashes is hard-coded at one second. |
300 ms |
