Usage Guidelines
This command enables PacketCable operations on all cable interfaces and takes effect immediately. If
you do not need to change any parameters from their default values, this is the only command needed to
enable PacketCable operations.
In Cisco IOS Release 12.2(11)BC1 and later releases, this command also automatically creates a random
Element ID for the CMTS that is in the range of 0 and 99,999. To ensure that this Element ID is unique
across the entire PacketCable domain, you should use the
PacketCable operations can be configured together with HCCP N+1 redundancy, but the PacketCable
Note
states are not synchronized between the Working and Protect interfaces. If a switchover occurs, existing
voice calls continue, but when the user hangs up, PacketCable event messages are not generated because
the Protect interface is not aware of the previous call states. However, new voice calls can be made and
proceed in the normal fashion.
Channel Width Limitations
The 200,000 Hz channel width cannot be used on upstreams that support PacketCable voice calls, or on
any upstreams that use Unsolicited Grant Service (UGS) or UGS with Activity Detection (UGS-AD)
service flows. Using this small a channel width with voice and other UGS/UGS-AD service flows results
in calls being rejected because of "DSA MULTIPLE ERRORS".
