5.37.3.2.2. Connections from External to Intern Previous topic Parent topic Child topic Next topic

An external incoming analog FAX or MODEM connection has to be routed without VC. Therefore, all internal fax and modem numbers must be listed in the WABE with a destination number which leads to a route without VC.
Based on the example of a route configuration in Section 57.3.1, "Mixed Routes (compressed/not compressed)", on page 723, additional new routes must be defined.

From Node 100 to 200:

ADD-RICHT:MODE=CD,CD=00202,LRTE=202,SVC=ALL,TGRP1=22,
CPS=0,DESTNO=22;

ADD-LDAT:LROUTE=202,LSVC=ALL,LVAL=1,ODR=1,LAUTH=1,TGRP=22;

From Node 100 to 300:

ADD-RICHT:MODE=CD,CD=00302,LRTE=302,SVC=ALL,TGRP1=32,
CPS=0,DESTNO=32;

ADD-LDAT:LROUTE=302,LSVC=ALL,LVAL=1,ODR=1,LAUTH=1,TGRP=22;

From Node 200 to 100:

ADD-RICHT:MODE=CD,CD=00102,LRTE=102,SVC=ALL,TGRP1=12,
CPS=0,DESTNO=12;

ADD-LDAT:LROUTE=102,LSVC=ALL,LVAL=1,ODR=1,LAUTH=1,TGRP=12;

From Node 200 to 300:

ADD-RICHT:MODE=CD,CD=00302,LRTE=302,SVC=ALL,TGRP1=32,
CPS=0,DESTNO=32;

ADD-LDAT:LROUTE=302,LSVC=ALL,LVAL=1,ODR=1,LAUTH=1,TGRP=32;

From Node 300 to 100:

ADD-RICHT:MODE=CD,CD=00102,LRTE=102,SVC=ALL,TGRP1=12,
CPS=0,DESTNO=12;

ADD-LDAT:LROUTE=102,LSVC=ALL,LVAL=1,ODR=1,LAUTH=1,TGRP=12;

From Node 300 to 200:

ADD-RICHT:MODE=CD,CD=00202,LRTE=202,SVC=ALL,TGRP1=22,
CPS=0,DESTNO=22;

ADD-LDAT:LROUTE=202,LSVC=ALL,LVAL=1,ODR=1,LAUTH=1,TGRP=22;
In the dialing plan of each node the new destination numbers have to be set for all FAX and MODEM subscriber numbers.
Node
Destination number for FAX/MODEM
Destination number for the other subscriber numbers
100
12
11
200
22
21
300
32
31
Example: The FAX subscriber 10123 of node 100 requires the following changes of the dialing plan in nodes 200 and 300:
CHANGE-WABE:CD=10123,DESTNO=12;
There is also the possibility to exclude all incoming connections of an external bundle from voice compression using a special COT parameter. See also Section 57.2.4, "Class of Trunk Configuration", on page 718.
In this case WABE modification is not necessary.
