One E1 for voice and digital modem...

[Mikhail Chernyakov]

Hello All!!!

My question is about remote access and Ip-telephony ...

I use cisco3825 with PVDM2-12DM NM-1CE1T1-PRI cards installed.

I have only one E1 channel.

Can I install on router IOS with CCME support and use this E1 for voice too?

How I can detect what call should be forwarded to CME or Digital modem?

Thank you very much...

You can't do that with the hardware that you have now.

I recommend you get the following:

one VWIC or VWIC2, with two ports.

and

one HWIC-1CE1T1-PRI that supports the DMs,

and

one PVDM2-64. (you cannot use the -32 because you have two ports)

and

IOS 12.4(11)XW6

One the VWIC one port you connect to telco. the other using with a crossed cable, you connect to the HWIC.

You route voice calls to the HWIC based on calling or called number. Automatic recognition of modem/voice calls is not supported.

Hope this helps, please rate post if it does!

Thank you very much!

But can I route voice calls to CME and modem calls to DM based on called number?

Note thinking better, you don't need the HWIC, because you have the NM already.

But you need all the other hardware I mentioned above.

Can I realize this using modem pool?

"Modems may be pooled so that specific ranges of the available modems are assigned to the various called numbers handled by your system."

Hi, as far as I know, modem pools is supported on the AS5xxx only.

Anyway, the requirement for the VWIC card is mainly because the NM that you have, doesn't support voice calls at all.
