remote office 9150

[westcoaster]

I have a site with a reach line card and a remote office 9150.
The opt 11 (and the reach line card) is back east and I am out west with the 9150. The customer has two 56k lines running east/west one for data and the other for voice (9150).
When I had first arrived on site the cisco 2600 router with a 56k connection (for voice) was connected to the customer data hub, and the 9150 was connected to the customer data hub. The customer data hub was connected via an adtran unit to a 56k data line back east.
This worked, but voice quality was not good. I suspected the source of the poor voice quality was in the customer data hub (too many broadcast messages that were being processed by the 9150) so I had removed the 9150 and the cisco router from the customer data hub, and had installed them on a separate stand alone hub containing only the 9150 and the cisco router. This cleared up the voice quality issues immediatly.
However... whenever the 56k line goes down for a moment the 9150 does not reconnect to the reach line card. I have tried to manually restart/shut down the 9150 to no avail. The only thing that appears to work is plugging the cisco router and the 9150 unit back into the customer data hub for a brief moment, waiting for the 9150 to establish contact, then unplugging from customer data hub and reconnecting to the stand alone hub and doing a restart on the 9150.

The basic question is, why won't the 9150 reestablish contact with the reach line card when the 56k line is interupted when the 9150 and cisco router are plugged into a stand alone hub??
Any help would be appriciated,
I am new at this and learning pdq, Thanks

There are a couple of things to look at. First are you testing this with no traffic on the 9150 (IE: any calls in progress). You need to look at whether your setup for permanent signaling or on demand in Configuration Manager. Then I would look at the RLC to see if what settings you have for QOS. You can setup how long it takes for the connection to reestablish. Also make sure if you don't have ISDN backups directly to the 9150 then make sure to turn off the failover in setup. Let me know!

There are no calls in progress when I am testing this, when it fails all call processing stops. (they can still make local calls through the isdn) Call processing stays stopped untill I unplug the patch cords from the stand alone hub, and connect them to the hub that has a separate 56k connection back east. the 9150 then comes up automatically. I then unplug the patch cords from the hub that is connected to their data network and plug them back into the 9150. Call processing dosn't start untill I restart the 9150.
It is set up for permanent signaling.
There is an isdn line connected to the 9150 but it is not set up for QOS yet.

There is something funny going on here and I am not sure if I am leading myself down the garden path with some of my testing, however, this is what I have to do to make it work again.

I know that in past releases they had isuues with failover but nothing like this. I would suggest reloading your firmware (make sure it is the latest) on both the 9150, RLC and the ISDN U/S BRI cards. Good Luck!
