2600 RNIS/CTN ,callback and backup

[sergeb_kaam]

Hello, I have two Cisco 2610XM. Each router has two wic on which we have two ports ISDN and 4 ports ISDN in extension. Only one is functional. I want the interfaces to take into account 4 ISDN at least and 8 CTN(commutated telephone network)modems integrated of preference?Which modules do I have to acquire? how can i have an identical configuration in the two routers automatically?Do i need to write a script?if yes please can I have an example?or do i need a specific commands? Finally which configuration to use to take into account the ISDN, the CTN, CALLBACK(on the functional router) and the BACKUP (to allow the swing). It is much of concern. Thanks

Not sure that i have understood your question and the list of hwrdware you have, but NM-8B-U card will allow you to have 8 BRI lines which you can multilink togather as many as you want to get aggregated bandwidth.

Or NM-1CT1-CSU to have Two T1/PRI lines

but looks like you have NM-2W (two port WIC module) which can hold WIC-1B-U. one in each WIC slot.

So pl. describe the parts with part number so that i can see what can be done..
