Nokia Status: Alarm

Posted on 2004-09-16

I'm not sure if the problem is my leased line or equipment.
My nokia line equipment (modem) is giving off an alarm status (blinking red LED).
However, inspecting my router, the router still detects the leased line ( line is up, line protocol is up).
I can ping servers at remote end, though at times I do get disconnected (destination unreachable)

Probably this can give a clue, it seems weird to me. From within my router, when I ping the IP
address of the serial interface of the remote router, success rate is 100%.
when I ping the ip address of the serial interface of my router, success rate is less than 100%.
My router is having a harder time pinging its own serial interface IP than the serial interface IP of remote router.

thanks for any help

rqs,

Okay well silly stuff first.

1. Have you disconnected the power to the Nokia?
2. Have you disconnected the power to the router?

Disconnect the power from the Nokia first then disconnect the power to the router. Bring it back up in order, Nokia then router.

----------------------------------------------------------

Can you beg, borrow, and/or steal another router for testing? Also what kind of router are you using? From what you have discribed it seems like the serial interface of your router is giving you grief? I am assuming the configuration of the router has not been changed, it just started popping alarm codes? If that's the case you really need to change out the router, copy the configuration to a new router and make  sure the serial port is or isn't functioning properly.

Hi,

Yes, the configuration of the router hasn't changed a bit before this happened. This alarm code just appeared.
I'm talking about at Cisco 2511 router.

I already tried closing and opening the router and Nokia modem in order. Status alarm still goes on.
As of this morning when I tested, I am now getting less than 100% when I ping both the
local serial interface IP and the remote serial interface IP.

I don't have any spare router to test/borrow anywhere near.

The router at the other end (not sure what model, but also Cisco),
already had problems with its serial interface and I know the module was already replaced
just about a month or two ago, and everything worked fine after that until know.

So the problem may not be with the leased line with my router serial interface? I hope not. =(
How will I be able to know it's not my leased line. Or it's not my modem or router?
Or even it's not the modem or router at the other end? What's the way of telling?

The modem now says "Qual D Rate 256   Status: Alarm".
Last week I think I read it to be "Qual A". The serial port LED on the router blinks green.

I already requested admin at remote end to phone the telco. Have no feedback so far.

Okay I would have suggested that you have the Telco run an end to end test of their HW, but you have already done that.

Now the bad part, is the router still under warrenty? If it is, have the serial port replaced if the end to end test from the telco comes out fine.

Ok, I think the telco finished running their end to end test.
The nokia no longer gives a status alarm. I ping both the remote and local serial port IPs and
things seem to be working fine now. =)

Just about thirty minutes after I saw that things were OK, down went the link again to status alarm.
It's blinking red again =(
I'll just talk to the telco and verify if the tests were OK. otherwise, the ports on my router maybe the culprit.....

If the telco ran the end to end tests, and your alarm was off, and everything worked for 30 minutes, that kinda points to the telco.
