Baseline Privacy Interface
The Cisco uBR7100 series CMTS supports 56-bit and 40-bit encryption/decryption; 56 bit is the default.
After you choose a CMTS image that supports BPI, BPI is enabled by default for the Cisco uBR7100
series routers.
When baseline privacy is enabled, the Cisco uBR7100 series router routes encrypted/decrypted packets
from a host or peer to another host or peer. BPI is configured with Key Encryption Keys (KEKs) and
traffic encryption keys (TEKs). A KEK is assigned to a cable modem based on the cable modem’s service
