Dear all, I have something of a problem I hoped someone might offer some advice on.
We have a 1721 router at each end of a 128k leased line. The line went down this morning, red alarm light on the CSU, router showed as Serial Interface Up, Line protocol down. Ok fair enough, reported the fault, telco claimed to repair the fault. Alarm light on CSU is no longer red but 'show interface serial0' still shows Interface Up, Line protocol down. I've power-cycled the routers with no joy. Engineers from the telco have actually come on site and performed an end to end test and are telling me it's fine. Looking at the advice offered here by Cisco: http://www.cisco.com/en/US/products/hw/routers/ps221/products_configuration_guide_chapter09186a008007cd3d.html#xtocid8 they tell me that the problem could be: The local or remote router, a problem with the leased line or a problem with the CSU/DSU. Great thanks, that's helpful!! Can anybody offer any suggestions on what might have gone wrong? It seems strange to me that a pair of routers that worked perfectly fine for 8 months have developed a fault at exactly the same time as the leased line did? How can I prove to the telco that it is their problem? The config of these routers is really simple by the way, 1 x Ethernet Interface, 1 x Serial (WIC) interface, static route, encapsulation ppp, no chap/pap, that's about it! Thanks, James.
