B3 BER thresholds:
SFBER = 1e-5,
Carrier delay is 200 msec
The show interface pos0 command shows scrambling.

Third-Party POS Interfaces

If a Cisco POS interface fails to come up when connected to a third-party device, confirm the scrambling
and cyclic redundancy check (CRC) settings as well as the advertised value in the C2 byte. On routers
from Juniper Networks, configuring RFC 2615 mode sets the following three parameters:
•
•
•
Previously, when scrambling was enabled, these third-party devices continued to use a C2 value of 0xCF,
which did not properly reflect the scrambled payload.
