Cisco 801 router

Is Cisco 801 routers compatible with the HP ISDN BRI J2460A ? If yes what is the best config for the Cisco router

Thanks

I had a look at the 801 router on CISCO web :
tp://www.cisco.com/univercd/cc/td/doc/pcat/800.htm , that tells me it is capable of connecting to external NT1 and to ISDN wall jackets , we have to look if the card describes does support NT1 signaling, apparently this card doesn't have a NT1 incorporated so we need a NT1 , can the CISCO provide it ? if so it could be connected directly but on the CISCO site I could find no info on that

the configuration is a little bit more tricky, in the router you would have to add something like ISDN switch-type then configure the rest of the routers interface , refer to CISCO manual for that

Hi,

lots of example configuration on http://www.cisco.com, simply search for "ISDN BRI SAMPLE".

If you need detailed debugging information, log into your cisco, and flip some debugging switches.

term mon
debug isdn events
debug isdn q931
debug ppp nego
debug ppp auth

If something fails, this should give you the reason why !

Hope this helps

If you mean can you connect an 801 directly to an HP's ISDN card then the answer is no. You need a telco switch in between. There is no simple crossover cable that you can use between two boxes you have to go through a network switch. (Both are the equivalent of DTE and there is no option for either to play DCE.)

If you mean can you connect an 801 to an ISDN circuit from the telco and dial up an HP via its ISDN card then the answer is yes.

Well, the two systems are compatible but the PPP protocol must be use (not X25) because X25 on HP ISDN BRI is not standard (HP dixit).

Thanks for your help.
