Static DID and two-way DID

When configuring static DID with two-way service, the
channels programmed as DID at the CO must be the lowest
B-channels on the PRI. On your Norstar system, the BchanSeq
mode must be set to descending. In this configuration, all
calls on the PRI must be Public service.
For example, channels 1 to 4 are configured as DID at the CO.
The CO uses ascending mode for B-channel selection, and the
ICS uses descending mode.
