E1 T1 Controllers

[ecisco1010]

Good day,

I have been newly in the field and trying to understand what is E1 or T1 controllers. I have finished my CCNA training and understand E1/T1 standards in ISDN. In my organization, they would ask sometimes to check the controller or serial interface and few times for ISDN line. I guess my theoretical knowledge needs help here. Any help, comments, suggestions would be highly appreciated.

Thanks in advance for taking time.

Regards.
