2821 & Multible T1's

I am looking at the 2821 and I need to support up to 4 T1's. The only multiport T1 card that I seem to find is a VWIC however, I do not need to support voice. I know that there is a WIC single port T1 card available but is there a multiport cards? Any suggestions would be great.

Re: 2821 & Multible T1's

Hi There,

What is the difference between VWIC-1MFT-T1* and VWIC-1MFT-T1-DI*.

Thanks...

Re: 2821 & Multible T1's

Hi there,

The VWIC cards are used for both voice AND data. Hence the "VWIC" and not just VIC or WIC.

You can even split up the channels and use some for data and some for voice, so if I were you - grab the VWIC-2MFT-T1's

Hope tha clarifys,

Hello ...

You can use the Multilink command to create a vitual interface bonding multiple T1s.

!

interface Multilink1

description Test Site

ip address 10.xxx.xx.x xxx.xxx.xxxx.xxxx

no cdp enable

ppp multilink

no ppp multilink fragmentation

multilink-group 1

end

Now the actual physical T1 interfaces:

!

interface Serial1/1/1:1

description Test Site T1 #1

no ip address

no ip redirects

no ip unreachables

no ip proxy-arp

encapsulation ppp

ip route-cache flow

ppp multilink

multilink-group 1

!

interface Serial1/1/2:1

description Test Site T1 #2

no ip address

no ip redirects

no ip unreachables

no ip proxy-arp

encapsulation ppp

ip route-cache flow

ppp multilink

multilink-group 1

!
