We are monitoring the datacenter for one of our customers head office based in chennai. one of their branch office which is located in banglore is facing problem.
The network setup is we have cisco 1841 router which has got one serial port, one BRI port and fa0/0 and fa0/1. We are using V.35 serial DB 60 cable to connect with the router and the modem.
The problem is : we cannot able to make the link up.
According to the service provider the there is no local lead fault.
So, at our end we have tried the possibilities - changing the router, WIC 1T card, DB 60 cable..And what else...
Still the we cannot make the Site UP. We are getting SERIAL IS UP but the LINE PROTOCOL IS DOWN.
Pl share your ideas on this. Pl question us for your more understanding on the problem.
Thanks In advance..
Expecting your reply.
