RE: [swinog] X.21, V.35 Cisco Interface in Master Mode
Hi André We've used this several times for customer connections at TIX. You need on one side a DTE and on the other side a DCE cable. As soon as the DCE cable is connected, can you set the clock rate on this I/F. -- X.21 up to 8Mbit/s Cheers, Günti -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Andre Oppermann Sent: Donnerstag, 1.

Yes we've used such back2back configurations for a long time with V.35 and X.21. The availble clockrates depend on the type of cisco-gear and serial-interface adapter you're using (not all clockrates shown with a 'config-if# clockrate ?' in cli are always possible !) -Patrick ___ swinog mailing list swinog@lists.swinog.ch http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog
Re: [swinog] X.21, V.35 Cisco Interface in Master Mode
Hello Andre Yes, we had such a setup for quite a long time for connecting two routers back-to-back without a leasedline with serial-interfaces. It was somehow more a case of 'we have the interfaces already so why should be buy some new ethernetinterfaces when the cables cost not even 10% of the interface-price' than a 'there is no other way to do it' case tough. But IMO such setups are more a lab-thing than real-live stuff in nowadays. -- Kind regards, Roman Hochuli Operations Manager Nexellent AG Saegereistrasse 29 8152 Glattbrugg Switzerland Tel +41-44-5623040 Fax +41-44-5623041 X-NCC-RegID: ch.nexellent Corry's Law: Paper is always strongest at the perforations. ___ swinog mailing list swinog@lists.swinog.ch http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog
