Connecting two (2) BCM 400 together in campus environment using fiber

[eorford]

Has anyone out there in a campused environment successfully connected 2 BCM400 systems together for ext to ext dialing and where one system is the host with LEC interface (ISDN/PRI/DID) and the other system is a remote using fiber cable?

I have a site that is connected to another building using approx. 1/2 mile of single mode fiber. I'm not aware of a fiber interface mod for BCM's so we used a fiber to copper converter and tied the systems using T1/DSI interface cards. It works with one exception, dropped calls.

All calls in and out bound route through the host system. Have tried adjusting timing, frequency and master/slave through resource media bay. Have had Nortel involved. Asking the question to see if this has been tried anywhere else!

I don't have any sites like you mention, but if I was to build one I would try linking them using IP instead.

IP trunking and a data network.

have something similar setup over MCDN and works fine , Fiber modems to extend the LAN between the two bcms ....E1 trunking to the main BCM and it's stable...

There is a Fiber Expansion Module (FEM) for the BCM available. You can use one of these, then a Fiber Module Extender to extend an FEM bus to the remote location where you connect it to a Fiber Station Module (Norstar Type). Once thats done, you have 16 extensions at the remote location.

Other than that, use VoIP trunks to connect two BCMs together as mentioned above...
