Configuring T1 Cards
Configuring T1 R1 and
the switch, you can also specify how long it waits before sending the request, and how long the ANIR signal lasts.
The following parameters enable R1 signaling on T1 lines and specify the timing of certain signals from the switch. These parameters are shown with their default settings:
[in T1/{
Parameter | Specifies |
For T1 R1 signaling, you must set | |
Enables/disables ANI processing (CLID). It is set to No by | |
| default. If set to Yes, the system performs ANI processing on |
| incoming calls. |
Time in milliseconds to wait for the first digit from the switch after | |
| sending the KP pulse. The default setting is 340 ms. The valid |
| range is from 0 to 1000. |
Time in milliseconds to wait before sending the ANIR signal after | |
| receipt of the ST pulse from the switch. The default setting is |
| 350 ms. The valid range is from 300 to 2000. |
Duration in milliseconds of the ANIR signal. The default setting is | |
| 200 ms. The valid range is from 180 to 400. |
Enables/disables a modified version R1 signaling that is required | |
| in Taiwan. It is set to No by default, which indicates regular R1 |
| signaling (described in the ITU recommendation Q.310- 332). |
| TAOS units located in Taiwan must set this parameter to Yes. |
