PRI Issue

[ciware]

Hello,

We have an Option 11c switch with three PRI loops. We began having problems last week on loop 1 with channels going into lockout. This is the second time in two years that this has happened.

I had disabled the card and called our telco provider. They have since fixed the problem on their end.

The problem now is that no one can use a dial-up with their modem. I attributed this to a clock problem and the CC indicator on loop 1 is now red. I went to ld 60 to find my clock source... here is the output:

.ssck 0
ENBL
CLOCK ACTIVE
SYSTEM CLOCK - TRACK ON SLOT 1
PREF - 1
SREF - FREE RUN
AUTO SWREF CLK - ENBL
NO ERROR
.

I have tried everything I can think of, but the indicator will simply not go green. Any suggestions?

Thank you all in advance!

How are your counters on loop 1(ld 60, LCNT)? You might have to disable the loop and remove the card then place it back in.

The SLIPD errors have been occuring since the clock went red (as they should). Everything else looks fine. I am boggled.

IF RESEATING THE CARD DOESN'T WORK YOU MAY HAVE TO REPLACE THE CLK CARD

Thanks everyone! Reseating the card worked. I actually had to power cycle the entire switch!
