ISDN trunk group
Issue 5 October 2002 963555-233-506
The Incoming Call Handling Treatment Table always automatically rearranges to
show the precedence order the system uses to pick an entry. Thus, you can easily
predict the behavior of the Incoming Call Handling Treatment Table by noting the
order in which the entries display. (The entries rearrange after submitting the trunk
group screen. A subsequent change trunk-group or display trunk-group command
then shows the rearranged order.)
Avaya MultiVantage traverses the table from top to bottom and picks the first
entry that matches all the following criteria:
■ The Service /Feature, if applicable, matches
■ The Called/Length matches
■ The Called Number matches
If the administered Called Length or Called Number is blank, that criterion is
considered successful.
Incoming Call Handling Treatment Table entries with a predefined service/feature
always appear before entries with a user-defined service/feature. To control the
order in which certain entries appear, you must use user-defined services/features
for those entries. For example, you can redefine the predefined mega800
service/feature as an identical user-defined entry with the name m800.
User-defined entries are always listed in the reverse order compared to the way
they appear on the ISDN Network-Facilities screen. See ‘‘Packet Gateway
Board’’ on page 1072. Thus, given two user-defined services/features ABC and
XYZ, you can force XYZ to appear before ABC in an Incoming Call Handling
Treatment Table by putting XYZ after ABC on the Network-Facilities screen.
NOTE:
DCS features that use the remote-tgs button (on the remote switch) do not
work when the local trunk group deletes or inserts digits on the incoming
call. These buttons try to dial a local TAC. Adding or deleting digits defeats
this operation and renders the remote feature inoperable. If digit
manipulation is needed, use it on the outgoing side, based on the routing
pattern. One reason for digit manipulation is insertion of the AAR feature
access code (FAC).
These fields are located on the Incoming Call Handling Treatment Table screen.
Called Len
Specifies the number of digits received for an incoming call. A blank entry is used
as a “wild card” entry and, when used, means that any length of digits associated
with the specified Service/Feature can match in this field. Valid entries are
0 to 21,
or leave blank.
