Hello Sudhir,

channelized interfaces require to configure a hierarchy:

first the underlying STM-1 controller has to be initialized then you need to configure the tributary controllers until you reach the E1 level.

see

http://www.cisco.com/en/US/docs/ios/12_4/interface/configuration/guide/h_stm5.html

this is for a PA in a flexwan, but the config should be similar for the SPA in the SIP.

this is the right link

http://www.cisco.com/en/US/docs/interfaces_modules/shared_port_adapters/configuration/7600series/76cfstm1.html

Hope to help

"thanks so the threshold is at 4500 points"

Yes not quite sure why it says 3750 as it has always been 4500.

"don't worry I will stay here at purple level for a while :-)"

No worries, it does seem to take forever to get out of purple tho :-)

Thanks a lot.!!!

But please clear this line as i am bit confused "first the underlying STM-1 controller has to be initialized then you need to configure the tributary controllers until you reach the E1 level".

Specially for tributary Controllers.

Hello Sudhir,

in simpler words:

you need to configure a controller that represents the whole STM-l link.

Then following the documentation you need to define some Virtual Containers (payload objects) until you can define a controller E1.

To be able to define an E1 you need first to define a VC that carries inside a T3 DS3 rate and then an E1

refer to the second link in my first post

Hope to help

Giuseppe
