Hello, I have a router 3825 with a card VWIC2-2MFT-T1/E1 and I need to configure two E1 links, but I need configure port-channelized E1 to put three links of 1 Mbps. How I can configure the E1 links I am confused in how split the time slots.
Thanks
Solved! Go to Solution.

Hello Adrian,
If they mentioned you need to configured timeslots 1-31, it means that it is a standard E1:
controller E1 1/0
channel-group 0 timeslots 1-31
However, there is an important detail you need to confirm: is this a voice or data circuit?
Now, if this were a regular data E1 and if you would need to remove the configuration from the already configured E1, just check the controller E1 configuration (show run | beg controller E1) and use 'no' before the 'channel-group x timeslots' command:
controller E1 1/0
no channel-group 0 timeslots 1-16
Once this is done, you can add the proper timeslot pattern:
controller E1 1/0
channel-group 0 timeslots 1-31
You can use this link if you need further details on E1 onfiguration:

With IP address under serial interface, and no PPP.

Get first the exact number of timeslots from telco.

Hello, the timeslots are from 1 to 31, the interface card E1 have one interface already configured with six channelized links I need how would be the process of erase the configuration of this channelized port, make the new configuration of 1 Mbps every one and make the configuration of the new port with only one link of 1 Mbps.
The distribution of links is:
E1 0/0/1 ------ two links of 1 Mbps every link
E1 0/1/0 ------ one link of 1 Mbps
Thanks.

If you have 1 Mbps circuit you will need to configure timeslots 1-16, but confirm that again with telco, as it is not very common.

Hello, my links are standard E1 so I have timeslots from 1-31, these E1 are only for data. I will make the process that you say with the "no" of channel-group command. The configuration that I think to make is:
controller E1 0/1/0
framing NO-CRC4
clock source internal
channel-group 1 timeslots 1-16
channel-group 2 timeslots 17-31
controller E1 0/1/1
framing NO-CRC4
clock source internal
channel-group 3 timeslots 1-16
interface Serial0/1/0:1
no ip address
encapsulation ppp
load-interval 30
ppp multilink
ppp multilink group 1
!
interface Serial0/1/0:2
no ip address
encapsulation ppp
load-interval 30
ppp multilink
ppp multilink group 2
interface Serial0/1/1:3

I am not sure if this configuration is correct, thanks for the help.

You should have only one multlink group, not three.
09-27-2012 05:32 AM
I need three WAN links and intend have my two E1 channelized to have three WAN links.
09-27-2012 07:27 AM
Then you don't need multilink PPP and in fact, if the other side is a Cisco router. you don't even need PPP.
09-27-2012 07:38 AM
Yes the other side is a Cisco router for all links. How could be the configuration please if in the branches I have satelital serial links but in the HQ I have these two E1s.
Thanks for the help.
09-27-2012 07:49 AM
With IP address under serial interface, and no PPP.

In the HQ I will have two E1 links to configure with three branches, in the other side there is a router Cisco with serial links to connect with the HQ. Can I configure this links with serial interfaces?
Thanks.

Yes, as answered above already.

Thanks for the help, it was very rewarding to me.
