Routing Outbound Calls - Lucent Technologies MAX 6000 Configuration Manual

Configuring call routing
Are both true: Excl Routing=No and the slot
parameter (Ch N Slot, B1 Slot, B2 Slot)=0 or null?
Is bearer service of call Voice and are digital
modems installed?
Is bearer service of call V.110?
If unit is not waiting for a second call of a dual-port
pair (invs-mux), answer the call on the first
available serial-host port that is not a secondary port
of a dual-port pair.
If unit is waiting for a second call of a dual-port
pair, answer call on that port if it is available.

Routing outbound calls

When the MAX unit dials out, it routes the outbound call from the originating slot to a WAN
channel to place the call. It looks for channels whose Ch N Trn Grp (or B1 Trnk Grp or B2
Trnk Grp) parameter matches the trunk-group prefix in the number dialed, that is, the prefix in
the Dial # setting of the Call profile used to place the call.
(Note that invs-mux calls have priority over other types of outgoing calls on those channels
whose Ch N Slot parameters point to invs-mux modules.) If no trunks have available channels,
the call is not placed.
Note: An available channel within the trunk group is one that is not assigned to any port (its
slot/numbers are zero) or is assigned to the port that originated the call. Channels assigned to
another port are not available.
Enabling trunk groups
A trunk group is a group of channels that has been assigned a number. If you enable trunk
groups, dial-out numbers must include a trunk-group number as a dialing prefix, and all
switched channels must be assigned a trunk-group number if they are to be available for
outbound calls. The following setting enables trunk groups:

Note: Trunk-group numbers 2 and 3 have special meaning, as described in the next two
sections. Only trunk groups 4–9 are available for assignment to channels.
