Configuring A T3 Channel - HP HSR6800 Configuration Manual

Step
5. Configure overhead bytes for
VC-4 frames.
6. Configure the specified E3
channel to operate in FE3
mode and configure a DSU
mode or subrate for the FE3
channel.
7. Configure the clock mode of
the E3 channel.
8. Enable loopback in the
specified mode on the E3
channel.
9. Set the national bit of the E3
channel.
10. Shut down the E3 channel.

Configuring a T3 channel

Step
1. Enter system view.
2. Enter CPOS interface view.
3. Create a serial interface
corresponding to the
unframed T3 channel.
4. Enable alarm signal detection
and generation on the T3
channel.
5. Enable a bit error rate test
(BERT) of the specified pattern
on the T3 channel.
6. Configure the clock mode of
the T3 channel.

Optional.
For an FE3 channel, the default
DSU mode is 1 (Kentrox) and the
default subrate is 34010 kbps.
Fractional E3 (FE3, or Subrate E3)
is a nonstandard application. With
FE3, you can subdivide the rate of
E3 into subrates depending on the
bandwidth requirements.
