About T3 interfaces

T3 belongs to the T-carrier system promoted by ANSI. T3 uses the digital signal level DS-3 and operates at 44.736 Mbps.

In T3 (unchannelized) mode, a T3 interface provides 44.736 Mbps of data bandwidth. No timeslots are divided. The system automatically creates a synchronous serial interface for it. The serial interface name uses the serial number/0:0 format.

The synchronous serial interface created in T3 mode has the same logical features as a standard synchronous serial interface and supports the following protocols:

• Data link layer protocols, such as PPP and HDLC.

• Network layer protocols, such as IP.

You can configure this interface in the same way a standard synchronous serial interface is configured.
