Susanna,


It's important to know how these modems are going bad. If you issue the command 'show modem' are the modems bad in pairs of 2, in pairs of 6, or the whole module at once?


A good start would be to upgrade to modem portware to 2.7.3.0. This solves a known issue where modems are going bad.



The software is on:

http://www.cisco.com/cgi-bin/tablebuild.pl/mica


If the issue remains, please open a TAC case, as further investigation is required then.
