Legacy Modem Connection over VWIC-1MFT-E1

Hi All,

I have a setup that I need to verify before I get in any trouble.

I have a 2811 router that is acting as a voice gateway on a network that has CCM 6.x. The router has a VWIC-1MFT-E1 card that terminates a digital E1/PRI trunk carrying 30 phone lines with a hunt group number.

The new requirement is a legacy machine in my environment that requires remote access over legacy analog telephone line. What I'm thinking of is adding a VIC-2FXS and connecting this modem directly to this FXS VIC. However I'm not quite sure if:

  1. FXS VICs support modem relay/pass-through?
  2. If it does, then what is the most suitable way to forward a call arriving on the digital trunk calling a hunt group number to a physical FXS port? Can I assign a DID number which can be auto-forwarded to the FXS port? Use the help of an operator to manually transfer the call?

I checked the usage of an ATA186 but apparently they don't support modem relay/pass-through !

I've attached a mini diagram to make it clear.

Help !!!

Regards,

Salem.

Salem,

1) Yes you can use the vic-2fxs

2) You can use thre dial peers to route the call to
the FXS/Modem

Lets say you have a spare DID E.G. 654329

This is called inbound via your E1

Build a dial peer something like this :-


!
!
dial-peer voice 1009 pots
desc *** MODEM PEER*
destination-patttern 654329
port 1/0/0
!
!
voice-port 1/0/0
desc *** MODEM PORT ***
cptone YOUR COUNTRY
!

Your call will be using POTS to POTS
so there is no issue with fax-modem pasthru or relay
