3COM NBX 100 - Make Change, Loose Remote Site?

3COM NBX 100 - Make Change, Loose Remote Site?

3COM NBX 100 - Make Change, Loose Remote Site?

Having a strange issue with a 3COM NBX 100. We have 2 sites, The main site is connected via a point to point T1 to the remote site with 3Com Routers and an uplink card in the remote cabinet.

Whenever we make any programing changes no matter how small we loose the remote site cabinet and phones when we apply the changes.

The remote site will come back up in about 15 minutes.

The main site is never affected.

Version 6.49 - been very stable for a long time

Any thoughts - ?
