With PC1.x services enabled, the C4/c CMTS accepts and maintains PacketCable COPS TCP connections to port 2126. In
addition, the C4/c CMTS processes PacketCable signaling messages from the Call Management Server and uses this
signaling to authorize call requests from the subscribers’ Multimedia Terminal Adapters (MTAs). Likewise, with PCMM
enabled, the C4/c CMTS accepts and maintains PacketCable COPS and TCP connections to port 3918.
Subscriber ID in DQoS Messages
To enable the use of a subscriber ID in DQoS gate-open and gate-close messages, enter:
configure packetcable gate send-subscriberID
By default, use of the subscriber ID is disabled.
To disable PacketCable services, issue the CLI command:
configure no packetcable
Or use one of the following to disable PC1.x or PCMM, specifically:
configure packetcable dqos shutdown
configure packetcable pcmm shutdown
When PacketCable services transition from enabled to disabled, then all PacketCable calls in progress are aborted and
signaling links to all C4/c CMTSs are torn down. If PCMM is shut down, all associated PacketCable gates are torn down and
all signaling links to the PSs are torn down.
PC1.x TimersPD
The following timers are specific to the PacketCable DQoS protocol. The C4/c CMTS functions properly in most
environments using the default values. In rare cases, the parameters may be modified through the use of CLI commands.
To set the threshold value of a particular timer of the C4/c CMTS, issue the CLI command:
configure packetcable dqos timer {timer name} <value>
Where: {timer name} is t0 or t1.
Timer T0 — timer T0 limits the amount of time between the reception of a Gate-Alloc message and a Gate-Set message for
the same DQoS Gate. The default is 30 seconds.
This timer has a range of 1 to 60 seconds.
Timer T1 — This timer limits the validity period for authorization of a particular PacketCable call. This timer is started
whenever a Gate is established and stopped whenever a Commit operation is performed on the resources authorized by
