We map "timeslot" to "s-port", which means we map 1 to 1 from DSO's to
S ports. However! That does NOT mean the Telco can not give us a
B channel on any DSO. With PRI, each user comes across a B channel.
The S ports are not exactally maped one to one on B channels.
Normally, when you set up 3 different hunt groups, it can go two
ways. You can say you want hunt group 1 to go from timeslot 1,
to timeslot 5, and hunt group 2 to go from timeslot 6, to timeslot 10.
Or, you can just set them up and the PM3 would designate between the
different hunt groups from the "Called-Station-ID" in Radius/ISDN,
sent across the D channel when assigning a B channel for the call.
