Greetings,


For the past 6 months i have set up a 876 router (DSLoISDN) which worked fine. Four days ago we lost DSL connection to the ISP. The ISP made a test and found out that his systems are ok and that there must be some kind of wrong config to our router!!!


I am going nuts but before that please give me any hint before I start screaming.


My actions are the following:


1. Checked NTU modem and is fine. Also replaced cabling and DSL filter just in case.

2. Router has following indications


'ON' is on

'Link' is on

'CD' is blinking


My Atm interface is setup in 'auto' dsl-operation mode with PPPoA and authentication credential good(tested again with ISP).


My atm status is down / down and when i issued the 'sh dsl int atm 0' i got the following:


rout3#sh dsl int atm0

ATM0

Alcatel 20190 chipset information


Line has not yet been activated.


Modem Status: Down (DMTDSL_DO_OPEN)

DSL Mode: Unknown

Interrupts: 61696 (0 spurious)

PHY Access Err: 0

Activations: 0

LED Status: OFF

LED On Time: 100

LED Off Time: 100

Init FW: init_AMR-3.0.014_no_bist.bin

Operation FW: AMR-3.0.014.bin

FW Source: embedded


DSL: Training log buffer capability is not enabled


Then i enabled training log and i attach you the output. Can anybody please help???


MANY thanks

Themis




PS I assume that the DSL port in my router is working since after a reset i see all indications and moreover from SDM i can enable/disable interface...
