The T4 port is a timing output port, most commonly used by telco providers in Europe.

Hello Racolvin

Thanks for the information.

Can you please tell me that T4 interface is a physical interface or logical interface?

Mukesh:

I'm not certain I follow the question, at least in this context, but I'll give it a shot ...

The T4 interface on the 4660 cannot be programmed to do anything else, nor can any other interface be programmed to be a T4 interface. So it's physical in the sense that the interface is physically there (obviously) and can't be used for any other purpose. It is not a logical interface in that the T4 timing function cannot be assigned to any other port.

Thanks for the information Racolvin.

I want to migrate this router with the Cisco router.

1) Can you please tell me which interface we can use on Cisco router to achieve the same task?

2) What is the benefit of this interface?

3) If we will not use this interface on Cisco router then what will happen?

I'm afraid I can't help you with the Cisco questions. You would need to contact someone at Cisco to know whether or not they have a similar interface. Again, the T4 interface is a timing-output-only interface. It's benefit is to synchronize a clocking signal to carrier level gear; if you don't have a use for that capability then the interface is useless to you and should be ignored.
