Channelised E1 leased Line

We have a typical type of scenario where customer has 30 differrent remote branches to be terminated to the central router.Omantel ( Service provider ) has suggested a channelised E1 leased line to the customer which will accomodate all the 30 branches in one with a 64k time slot reserved for each branch.This distribution of time slots will be done from the exchange itself.

We will have to suggest a cisco solution on this basis.At remote branches we can go for any small router say 1721 with WIC-1T.What kind of module is required at the central router to terminate this channelised E1 leased line and how it will work.

I also need help in configuring the same channelised E1 Port , if you can send me a sample configuration file.How the differrent 30 remote branches will be configured at this single channelised E1 port. The protocol used will be IP only.

Re: Channelised E1 leased Line


u need to install 1 Channelized E1/PRI port in u r router. simple config of the channelised E1 card ..

controller E1 2/0

framing NO-CRC4

channel-group 0 timeslots 1

channel-group 1 timeslots 2

channel-group 2 timeslots 3

channel-group 3 timeslots 4

channel-group 4 timeslots 5

channel-group 5 timeslots 6

channel-group 6 timeslots 7

channel-group 7 timeslots 8

channel-group 8 timeslots 9

channel-group 9 timeslots 10

channel-group 10 timeslots 11

channel-group 11 timeslots 12

channel-group 12 timeslots 13

channel-group 13 timeslots 14

channel-group 14 timeslots 15

channel-group 15 timeslots 16

channel-group 16 timeslots 17

channel-group 17 timeslots 18

channel-group 18 timeslots 19

channel-group 19 timeslots 20

channel-group 20 timeslots 21

channel-group 21 timeslots 22

channel-group 22 timeslots 23

channel-group 23 timeslots 24

channel-group 24 timeslots 25

channel-group 25 timeslots 26

channel-group 26 timeslots 27

channel-group 27 timeslots 28

channel-group 28 timeslots 29

channel-group 29 timeslots 30

channel-group 30 timeslots 31

then u need to configure the corresponding port where the card is goinge to be installed.

consider if u r installing @ the 1st slot,u need to configure like the following..

interface Serial1/0:0

ip address x.x.x.x y.y.y.y




interface Serial1/0:30

ip address a.a.a.a b.b.b.b

like this u need to configure all the 30 slots which r getting connected to the remote locations.other things like configuring encap,ratelimit,traffi-shape etc., is similar to configuring a simple serial port.
