We have an Adtran 3200 router connecting a Verizon T1. Every morning, the circuit goes down. Reboot doesnt work. When I call Verizon, they say that they will test the circuit. They call back and tell me that they tested clean till our smart jack. They just blame the router and close the case. This has been happening for the last 20 days. The funny part is that when ever they test teh circuit, it comes back up. The next day, it goes down. The Adtran config is as follows :
interface eth 0/1
ip address 22.214.171.124 255.255.255.224
interface t1 1/1
tdm-group 1 timeslots 1-24 speed 64
interface hdlc 1
description PTM 1.5M CID DS1IT-11340989
ip address 126.96.36.199 255.255.255.252
cross-connect 1 t1 1/1 1 hdlc 1
ip route 0.0.0.0 0.0.0.0 188.8.131.52
I got tired and shipped out a 2600 with a WIC-1DSU-T1.
The 2600 config is as follows:
Interface serial 0/0
service-module t1 clock source line
service-module t1 timeslots 1-24 speed 64
service-module t1 framing esf
service-module t1 linecode b8zs
ip address x.x.x.x 255.255.255.x
This is a remote site. When I ask some one to disconnect Adtran and plug in the cisco, I can ping the external interface from my location and I can telnet to the router, but only for about 1 minute. The connection goes bad after that. Am I missing something on the config?
It has been 20 days and over 50 calls with Verizon blaming our router or cables who say that they are testing clean till our smart jack. Could someone please help me?
