Hi all,
I've a Cisco Router 1720 connected to a Cisco 5400 NAS via an E1.....The E1
is connected from one side to the Router's serial interface and from the
other side to the NAS controller E1 7/5
Router config
int s0
en ppp
ip add 172.31.19.161 255.255.255.252
NAS config
controller E1 7/5
framing NO-CRC4
channel-group 0 timeslots 1-31
interface Serial7/5:0
ip address 172.31.19.162 255.255.255.252
encapsulation ppp
The problem is that I've the controller E1 7/5 up and interface Serial7/5:0
up/up and the Router's s0 is also up/up but the ping fails on that
interface.
Can anyone suggest why the ping didn't work although L1 and L2 are up.
Regards,
Komy

It will not work.
One side Channelised E1 (NAS) other side unframed E1(serial at 1721)
You require either both the sides unframed/framed-channelised E1.

Is there a TELCO provider inbetween Router and NAS.
Else are you using any CSU (modem) or directly connected ?
Can you paste the diagram of connectivity ?
