Support for 2-channel calls on one SPID
If your switch type is AT&T 5ESS NI-1, you can reuse the same Channel
Endpoint Suffix (CES) for a 2-channel call (one voice and one data) on the same
service provider identifier (SPID).
The same CES can be reused to support 2-channel calls under the following
circumstances (this information is for provisioning the line):
• The call is data on a specific CES.
• Phone Number Binding is TRUE and the new call attempt is voice over a
specific CES currently assigned to a data call.
Note:
This is not available if your switch type is DMS-100 NI-1.
Configuring a 2-channel, single SPID call
To configure 2-channel calls, perform the following steps:
1
Open the Configure menu.
2
Set My Num A to a valid phone number.
3
Set SPID 1 to a valid service profile ID. This value is copied to SPID 2.
4
Set Data Usage to A.
5
Set both Phone 1 Usage and Phone 2 Usage to A or both to None.
6
Set Phone Num Binding to Yes.
Support for outgoing 3.1K audio calls
Some fax machines and other devices (particularly in Japan) only accept calls
which indicate 3.1K audio in the ISDN SETUP message. You can enable 3.1K
audio for either POTS port for outgoing calls. The Pipeline will accept either
Speech or 3.1K audio calls.
