Dear Friends,
I have configured a Channelised STM (With Respect to E1 2048 kbps, i.e 63 E1s or serial sub-interfaces) on cisco 7613 router. SONET port is properly reflecting as channelised now.
The view of serial sub-interfaces after channelising is like this. Latest log captured from router for two serials .
interface Serial1/0/0.1/1/1/1:0
no ip address
!
interface Serial1/0/0.1/1/1/2:0
no ip address
But I have some confusion about configs. Lets take few examples.
Eg No. 1 --> If I have to configure 512k for customer on Serial Interface âSerial1/0/0.1/1/1/1:0â. Then my querry is , how can i make E1 as framed and after making E1 as framed (for 512k) what about rest bandwidth on that channelised serial i.e 2048k-512k = 1536k is that wasted or can we use it for some other customer as carry forward bandwidth (sort of) & Would it affect next serial interface configs. If anyone have working configs then please share.
Eg No 2 --> If I need to configure a customer for 6 Mb. Then how to make bundle of Channelised serial interfaces. ( as for providing the requested bandwidth we need to bundle 3 Serial Channelised serial interfaces). For better understanding Kindly share working scenerioâ¦Pls.

see the following lnik,
Q1.
In STM 1 card you get only E1 (you cannot configure framed E1 i.e less than E1). You can do that in Channelized T1/E1 card.
Q2.
Youcan bundle upto 12E1 in a bundle. For commands look for create multilink bundlein thelink above.

Hi,
In regards to the previous answer (1), yes you can have only 8 timeslots assigned to that interface and have the other 24 for other interface. You just have to configure:
controller AU-4-TUG-3 1/0/0.1/1
mode c-12
tug-1 1 e1 1 channel-group 0 timeslots 1-8
So the next Serial interface can be created as:
tug-1 1 e1 1 channel-group 1 timeslots 9-31
The second question, I think the best would be to bundle them at layer 2 level (by using PPP Multilink or Frame-relay Multilink) regardles of the fact that this interfaces are channelized.
Regards!

@ lucasiglesias ,
Thanks , But as mentioned:-
tug-1 1 e1 1 channel-group 1 timeslots 9-31
...Is that Tug-2 or Tug-1 . I suppose this should be Tug-2.
