T1 Going up and down

[Bcpaul]

Hello anyone,

Can anyone give me a tip about how to monitor a T1 thats swinging every few hrs.
Are there errors i can see if the DTI card is responsible?

rcnt.. load 60 will take the counters back to 0.. your slips are usually caused by a clocking issue.. when the lcnt is = to you trsh value in ld 72 ddb (i think, my switch is at work, i'm not) ddb.. your t1 will go down.

I find bypassing the csu/dsu and monitoring the T-1 connected only from the smart jack to the DTI card Helpfull. If the T-1 stays up not connected to a T-1 CSU then your CSU was the problem. Change out the CSU.

Well the T-1 is not going out of service according to the readings. Is this T-1 the primary clocking source. LOSFA is loss of frame alignment counter and SLIPD is frame slip deletion counter. I would check your clocking to see if this is causing this. Check your T-1 clocking in LD 60 and print it out. Send it back to the Forum.

FROM MY EXPERIENCE WHENEVER YOU SEE SLIPD ERRORS THEY ARE FROM A MISMATCH. FOR EXAMPLE THE T1 SHOULD BE ESF B8ZS AND SOMEONE ALONG THE WAY IS SET TO ESF AMI. TURN IT OVER TO YOUR T1 VENDOR

have you reloaded you tmdi and dch with a fdl command.. chances are it is not your switch but always helps to check before you start screaming at your vendor
