Configuring A Ct3 Interface In Ct3 Mode - HP MSR Router Series Configuration Manual

Step
15. (Optional.) Bring up the CT3
interface.
16. Return to system view.
17. Enter synchronous serial
interface view of an interface
formed on a CT3 interface.
18. Set the CRC mode.
Serial interfaces created on CT3 interfaces support the following protocols:
Data link layer protocols, such as PPP and HDLC.
•
Network layer protocol IP.

Configuring a CT3 interface in CT3 mode

When you change the interface state during the configuration, make sure you understand the following
information:
• Shutting down or bringing up a CT3 interface also shuts down or brings up all its lines and serial
interfaces, including:
T1 lines demultiplexed from the CT3 interface.
Serial interfaces created for unframed T1 lines.
The serial interfaces created for channel sets on framed T1 lines.
Shutting down or bringing up a T1 line also shuts down or brings up the serial interface created for
•
it.
• To shut down or bring up only the serial interface for a T3, unframed T1, or framed T1 channel, use
the shutdown or undo shutdown command in serial interface view.
To configure a CT3 interface in CE3 mode:
Step
1. Enter system view.
2. Enter CT3 interface view.
