Hello,
I have an AS5300 router. I want to use one of the router's e1 ports for leased line.
I can't see any problem with this but it doesn't work. The line protocol
is down... What could be the problem? I'm able to see the loop at the far end so
the line seems to be ok.
Thanks,
Andras
Here is the config of the AS5300
controller E1 0
clock source line primary
line-termination 75-ohm

ip address 192.168.18.33 255.255.255.252
encapsulation ppp

Here are the outputs of the sh commands:

The major problem here is that your 5300 is treating the connection as a channelized circuit while the remote end is treating it as a straight (unchannelized) data circuit.

Rick,
Thanks for your reply. That is true. But I have plenty
other routers which works quite the same way. Those are c3640 routers and I'm using NM-2CE1U= controllers
at my end and plain wic-1t at the customers' end
for the leased line connection. So the main
difference is that the e1 ports in the AS5300 are
channelized but the NM-2CE1U= ports are unchannelized? I don't think so. Here is a part
from a sh controll e1 0/1 command from a c3640:
E1 0/1 is up.
Applique type is Channelized E1 - unbalanced
No alarms detected.

let me answer my own question, maybe somebody else
would run into the same issue in the future.
It seems that it was an ios bug in c5300-is-mz.121-4a.bin ios. I did an upgrade to
c5300-is-mz.121-27b.bin and everything works fine.

Thanks for posting with the solution. It helps make the forum more useful when we can read about a problem and then can see what the solution to the problem is. I encourage you to continue to be active in the NetPro forum.

where can we see the remote end is treating it as a straight (unchannelized) data circuit?thx
