Hi Floks ;

i have a problem and i need some help if anyone has done ATM CES config before .

I have 4 ports CES card of LS1010 box , 2 ports are Connecting to NEC PBX using unstructured E1 (30 channel) service .

setup is like this

(HQ PBX)----E1----(LS1010-CES)----{ATM cloud}---(LS1010-CES)----E1--(SITE PBX)

instead of single E1 in the diagram I have 2 and two PVCs for the ATM cloud

The problem is that when I enable the two ports together ..only one at a time can pass the calls ..after while the two ports swich
over ..the working one becomes not working and the second one work ..this happens periodically .

I believe this is Clocking problem (not sure)

The configuration of both site are as follows

=====================
HQ config

network-clock-select 1 CBR9/0/0
!
interface CBR9/0/0
 ces circuit 0 circuit-name HQ1
 ces pvc 0 interface ATM9/1/0 vpi 2 vci 100
!
interface CBR9/0/1
 ces circuit 0 circuit-name HQ2
 ces pvc 0 interface ATM9/1/0 vpi 2 vci 99
!
=========================

SITE config is

network-clock-select 1 CBR11/0/0
network-clock-select 2 CBR11/0/1

!
interface CBR11/0/0
 ces circuit 0 circuit-name HQ1
 ces pvc 0 interface ATM12/1/0 vpi 2 vci 100

!
interface CBR11/0/1
ces circuit 0 circuit-name HQ2
ces pvc 0 interface ATM12/1/0 vpi 2 vci 99
!

--------------------------------------------

I appreciate if anyone has faced something like this configutiation before and at least have sort of configuration example about clocking ?

regards
