Re: ISDN over two switched T1 channels? [7:21551]

2001-10-01 Thread MADMAN

That's an interesting question and I don't have a definitive answer
but off the cuff I would think that yes you should be able to do this. 
One of the reasons for switched services was in the not-to-distant past
there were lots of analog CO's that could not offer digital, i.e. ISDN
services but these anolog CO's were/are not an island unto themselves.

 I've got an ISDN PRI back at the home office and 6 routers that dial into

 backups via their ISDN BRI connections. I have been told by my service

 that I can use two switched 56K channels off of an existing T1 at another
 site
 to dial into the ISDN PRI. I have been looking to try and find some kind of
 sample configuration to do this. I'm not even sure how this would work.
Could
 anyone steer me in the right direction? I have searched through Cisco's web
 site, without much success and TAC is still researching it for me, but I'm
 not
 sure they are confident it can be done. The remote site router has a 2600
 series
 router with a WIC DSU T1 card. The home office has a 3600 with an ISDN PRI
 card.
 
 Thanks!

This is true.  It is actually simple.  Configure your serial interface to
autodiscover the external Switched 56 CSU.  Then setup a standard dial
string, dialer profile, or legacy DDR config.  It is EXACTLY like dialing
out a serial interface using an external modem and a DB60 pin to DB25 pin
Cisco Serial to Modem/Codex cable.  Your PRI will autonegotiate down to 56K
instead of 64K just like when it answers a modem.  You may require the
isdn incoming-voice data on your PRI serial config.
