Cabletron Systems 1800 - Manual (Page 119)

Configuring X.25 8-27
To resolve any differences in addressing conventions, the backup path invokes a trans-
lation of the called and calling addresses. The SmartSwitch 1800-compatible called
and calling addresses are translated into PDN-compatible called and calling addresses.
Node 2 has a translation template defined to intercept packets with the PDN-com-
patible calling address for node 1. It translates these into the SmartSwitch 1800-com-
patible calling address for node 2. (The backup routing is transparent.)
To display existing translation templates, press [A] at the X.25 Address Translation
Templates Menu.

[A],[C],[C],[A] from Main Menu
The data between lines is structured to match the headings at the top of the
screen.
To add or change a translation template, press [B] at the X.25 Address Translation
Templates Menu and enter:
● Port . (The default is 0 .) Valid port numbers depend on the model of SmartSwitch
1800—see port locations on page 6-1 .
● Direction , I (for incoming packets) or O (for outgoing packets). (The default is I .)
● Template ID , up to 31 characters (including the G and U separators described
below), in the format:
aaaaaaaaaaaaaGbbbbbbbbbbbbbbUddddddddddddddd
where:
aaaaaaaaaaaaaa is up to 15 digits of called address,
G is the letter "G," which precedes any calling address,
bbbbbbbbbbbbbb is up to 15 digits of calling address,
U is the letter "U," which precedes any user data, and
ddddddddddd is a user data field of up to 12 numeric characters.
