Configuring a T3 interface

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.

Procedure

Step
1. Enter system view.
2. Enter T3 interface view.
3. Create a serial interface for
the T3 interface.
4. (Optional.) Configure the
interface to operate in FT3
mode and set the subrate.
5. (Optional.) Configure the
interface description.
6. Set the clock mode.
7. Set the cable length.
8. (Optional.) Set the loopback
mode.
9. (Optional.) Configure alarm
signal detection/sending.
10. (Optional.) Restore the
default settings for the T3
interface.
11. (Optional.) Bring up the T3
interface.

Remarks
N/A
N/A
By default, no serial interfaces are
created for a T3 interface.
By default, the subrate is 44210
kbps.
By default, the description of an
interface is interface-name
Interface.
The default clock mode for the T3
interface is slave, which is line
clock.
The default is 14.9 meters (49
feet).
By default, loopback is disabled.
By default, alarm signal detection
is enabled and alarm signal
sending is disabled.
N/A
By default, a T3 interface is up.
