Re: How to prevent glare in SC2200

In the SS7 IC for Voice Gateway this function is performed on the NAS to initiate the call back to the PSTN (VOIP to PSTN direction -

The other direction is chosen by the SSP in the PSTN). You can set B channel to ascending or descending in the NAS.

You do this under the serial interface of the D channel:

conf t

int ser 0:23

isdn bchan-num-order

By default the NAS uses descending. (Controller 3 2 1 0)

When coding ascending it uses controller 0 1 2 3. It uses

DS0s 1-24 with ascending and 24-1 for descending.
