Step
6. Set the maximum number of
keepalive attempts.
7. Set the clock mode.
8. Set the CRC length.
9. (Optional.) Set the loopback
mode.
10. Configure the overhead
bytes.
11. (Optional.) Ignore CRC of the
J1 byte.
12. Set the framing format.

protocol.
15. Set the MTU.
16. (Optional.) Set the signal
degrade (SD) or signal fail
(SF) alarm threshold for the
interface.
17. (Optional.) Configure the
action to take when an RDI,
SD, or SF alarm occurs on
the POS interface.
18. Set the rate of the interface.
19. Set the physical state
change suppression interval
on the interface.
20. (Optional.) Enable interface
dampening on the interface.
21. Configure the expected
bandwidth of the interface.
22. (Optional.) Restore the
default settings for the POS
interface.

Remarks
The default setting is 5.
The interface determines that the
remote end is down if it does not
receive a keepalive response
after the maximum number of
keepalive attempts have been
made.
The default setting is slave.
The default setting is 32 bits.
By default, loopback is disabled.
By default:
•
The C2 byte is 0x16.
•
The system uses the SDH
framing format.
•
In SDH frames, both J0 and
J1 bytes are empty strings.
By default, CRC is performed for
the J1 byte.
The default setting is SDH.
By default, payload scrambling is
enabled.
The default setting is PPP.
The default setting is 1500 bytes.
By default, the SD threshold is
10e to the power of negative 6
–6
(10e ). The SF threshold is 10e
to the power of negative 3 (10e
By default, the device does not
take any actions on the interface
when an RDI, SD, or SF alarm
occurs.
The default setting is 155 Mbps.
The default setting is 0
milliseconds.
By default, interface dampening is
disabled on POS interfaces.
y default, the expected bandwidth
n kbps) is the interface baud rate
