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.
