E1 flap

[Ahmed Yassin]

Dear all,

E1 flap during the past last 3 weeks, and you recommended me this command:

network-clock-select 1 E1 0/1/0

It looks good as this command made 0 Slip Secs & 0 Errored Sec.

But, E1 still flap again, if i can increase the priority again from 1 to 8 or it will do nothing and if so, no other recommendation can be done from my side.

How many flaps?

How your E1 cable is made ?

[Ahmed Yassin]

E1 cable is 2 pairs and made from 3 years ago from starting of E1 service.

It working but suddenly down then up again at the same moment. So, any call will be terminated.

I am talking about the command shown aboe, if i can increase the priority or no.

[paolo bevilacqua]

I was asking: how many flaps do you have each day ?

Changing priority doesn't make a difference.

[Ahmed Yassin]

E1 flaps rondomly, may be a lot per day and may be few.

But, occurs during any exist call which make it down.

Please, find attached E1 debug.

Appreciated
