Dial up connection in Cisco 7204 VXR

[ayram23]

Dear All,

Can I use a Channelized E-1 Card (in Cisco 7204VXR) for providing dial up(PSTN ) Connection to remote end?

The setup will be placed in the service provider end.

I will be using a DB-15 to RJ-45 Connector to connect the channelized E-1 port to a Multiplexer. Now will the dialer through PSTN connection can get connected to the Channelized E-1 Ports ?

Hi Raja,

I have a 3640 having an E1 card taking in dialin connections.. you can as well do it on a 7204.. you need to configure the E1 as CAS, and assign proper values to have the dialin of calls into the E1...

config will be similar to this:

controller E1 0/0

framing NO-CRC4

ds0-group 1 timeslots 1-15,17-31 type r2-digital r2-compelled

cas-custom 1

country colombia

debounce-time 25

seizure-ack-time 50

dnis-digits min 1 max 7

chat-script offhook "" "ATH1" OK

chat-script callback ABORT ERROR ABORT BUSY "" "ATZ" OK "ATDT \T" TIMEOUT60 CONNECT \c

modemcap entry TACD:MSC=&F&D2S0=0S34=18000S40=10S10=50S21=0S29=1S32=1S39=5S41=2

Thanks for your reply Raj.

But i want to know whether i require any modem / Converter to make this solution work.

Whether i require a digital modem in my router to make this solution work. And i dont think so that Cisco 7204 Router supports R2 Protocol......

Kindly help me in resolving the same.
