You mean with the BONDING protocol?

The Cisco B will need to setup a 2-channel BONDING call....*can* it do that?

>	(2)	As adviced by Cisco, in V.25Bis dialing, the Cisco router (Cisco A)
can only issue the CRN command string to the Ascend but is unable to issue
CRS. Thus, the router is not able to select profile resident in the Ascend
box. This is a limitation as the customer would like to dial different
sites using different profiles. Can the Ascend box utilize different
profile using only the CRN string sent by the Cisco router ?

As long as the only thing that will change is the number to dial (so the
protocol,
number of channels etc. is consistent), then the CRN command is sufficient.
Just
assign different numbers to dial with the CRN command.

I'm not sure of workarounds from the Cisco dialing, as it needs to be
able to request a 2-channel connection....
