SLIPD problems....

[StinkTech]

Two PRI's SLIPD counts on both increment one after the other. USLec states there is no problem on their end. This all started after lightning strike took out one of the PRI cards. Replaced along with Clock Controller.

We go directly from the Smart Jack to the PRI Card (No CSU's)

Any Ideas would be greatly apprectiated.

Is your clock controller locked and tracking on the primary source?

LD 60
ssck 0 or ssck 1 to verify

errors, hits, clocks etc don't have a lot of effect.. red alarms are open layer one.. when your t1 gets disconnected from the provider for any reason the error table will take hits.. after you have copper back, clear the alarms, they are not pointing to the real problem.. just a snap shot of what was hasppening when someone stepped on the copper..

I would say make sure that your primary clock source is on a reliable T (not like a point to point) and can you tell us if you had a CSU before, or you never did. A CSU will provide "zero code suppression" for a circuit so that you don't end up with frame loss, which could take down the circuit. I like to keep CSUs as "conditioners" for my cirtcuits.

Thanks for all your input... Here's the latest...

This all started after a lightning strike took out one of the PRI Cards. We replaced the PRI card, Clock Controller & DChannel card. (The PRI Cards are NOT the TMDI version) (System has two PRI Cards w/2 DChannels)

USLec came out with their test equipment and it shows the incoming clocking frequency at 1544000 and the phone system frequency at 1543998 (2 Hz off). If the incoming frequency changes to 1544001 the phone frequency shifts also to 1543999 again the 2 Hz off.

The CC is currently in Slot 1. During testing we moved it to slot 2, Replaced with a different PRI card, CC card & DChannel card. We then swapped out the cabinet and power supply. Still slipping.

The only thing left I can think of might be the ssc card. Any ideas?

Thanks,
Stink
