Channelized E1

[rajeshk200_2]

Hi all ,

i have requirement for connecting 20 branches with HO.

Can i have channelized E1 at the HO & point to point leased line circuits in the branches ?

if yes can u give me the sample config on the HO SIDE .

Thanx in advance.

Rgds,

Hi Rajesh

Yes you can do it. Here you are a sample config:

controller E1 1/0

channel-group 1 timeslots 1

channel-group 2 timeslots 2

channel-group 3 timeslots 3

channel-group 4 timeslots 4

...

channel-group 19 timeslots 19

channel-group 20 timeslots 20

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

interface Serial1/0:1

description branch1

ip address ...

encapsulation ppp

!

interface Serial1/0:2

description branch2

ip address ...

encapsulation ppp

....

interface Serial1/0:20

description branch20

ip address ...

encapsulation ppp

Be careful with the IP addressing scheme.

Hope this helps

Hi,

Thanx for the response .

since we r having P2P serial leased line in the branches . is service provider will give datail? for eg :

channel one for branch --1

channel 2 for branch --2

.........

channel 20 for branch ---20.

i hope it should not interchageable

suppose if we need more bandwidth for one particular branch we need to inform service provider beforehand only ( correct me if i am wrong ) right.

You are right Rajesh. Before doing any configuration you have to check E1 line and timeslots distribution with your service provider. This is very important.

As you know, with the configuration I've posted you have 64 Kbps BW per branch. So if you want more BW in any branch you should add more timeslots and tell your provider.

Hi Rajesh,

if you use only one channel for connecting to branch office, bandwidth will be only 64 kbps.so according to the requirement you can map one or two channel's, so plan it properly.

I believe there will be only one E1 link at the H.O
