Making voice calls over IDSL
To make voice calls, your service must be connected to Ascend-supplied IDSL
COE and the Pipeline must use the IDSL switch type, which supports Q.931 en-
bloc dialing. Only when the switch supports en-bloc dialing, can you make voice
calls. En-bloc dialing reports the dialed number in the set up message sent to the
COE, which uses the information to route the call to the voice network.
To make voice calls over IDSL you must use the IDSL switch type and you must
obtain a trunk group number from the central office administrator. The trunk
group number actually receives the call and routes it to the voice network.
To dial a call, enter the trunk number, followed by the phone number, followed by
the # key, which tells the COE that you have entered the entire phone number and
to initiate the call.
For example, to dial the number 5551234 using a trunk group number of 2, dial
25551234#.
To dial 1-800-555-1234 using a trunk group number of 2, dial 218005551234#.
If you omit the trunk group, the call is terminated at the central office equipment
(COE). If you omit the pound sign (#), the call is not initiated.
