LCR Trunk Groups

Software Version: All Versions
Address: FF8 6# (TrunkGrp)# (Position)# (Trunk)#
Description
Use this address to build LCR trunk groups, which are assigned to priority
positions in Time Priority Route Tables (see FF8 5#).
Each LCR trunk group can contain up to 8 trunks. A maximum of 8 different
trunk groups can be created. Within each trunk group, the trunks are assigned
to positions from the highest priority (position 1) to the lowest (position 8).
When a call is routed to the trunk group, LCR will try the trunk in the first
position, then the second position, etc.
LCR trunk groups are also used for assigning Add or Delete digits as a prefix
to dialed numbers routed to the trunk group (see FF8 7# and 8#).

Notes
Trunk Assignment to LCR Trunk Groups. A trunk cannot be assigned to
more than one position within the same LCR trunk group. However, the
same trunk can be assigned to several different groups.
Avoiding Glare. Glare occurs when both ends of a trunk are seized at the
same time, causing accidental connection between an incoming caller and a
DBS extension user preparing to make an outside call. Since incoming calls
will access DBS trunks starting from the lowest to the highest trunk number,
glare can be avoided by routing outgoing calls to the highest-numbered trunks
first. So, when you build LCR trunk groups, assign trunks in descending
order (from highest to lowest trunk number) to trunk group positions in
ascending order (from lowest to highest position). For example, assign trunk
7 to position 1; trunk 6 to position 2, trunk 5 to position 3, etc.
