How do you connect & configure CUCM Server to E1 connection?

[Carlos Silva Sosa]

I have a CUCM Server installed in a UCS C200. UCS it is connected to the LAN. Someone has given me a E1 connection (two RJ45 - Coaxial) for communication to the Telephony Central.

Where should I have to connect this E1 to the CUCM?

If you're asking about a voice E1 you do not connect anything into CUCM, you need an ISR with an E1 card and PVDMs.

Ok. you are saying that I must have a Router ISR with a wic E1 in the same LAN that the CUCM and then. What do I have to configure in both for to UP the Calling to Outside????

[Jaime Valencia]

Completely depends on what protocol you want to use.

There are guides for both MGCP and H323 on CCO.

In this case I'd like to use H323. But I do not what is CCO? What's the link?

Are there some useful PDFs for this request?

Thank you in advanced.

Carlos:

As javalenc mentioned you will need a Cisco ISR with the following cards:

- E1 vwic

- PVDM memory: sizing depending on the codec used and the amount of simultaneus call needed in the E1 - (Max 30)

For the E1 you will need to find our some info from the other side:

- Framing

- Linecode

- Time slots

- Clock source

If you want to avoid to use an ISR you can use a E1 gateway with a SIP trunk to the CUCM.
