Packet Voice Processor Commands Manual
Table 3-4 describes the process for provisioning a OOB signaling port on the Switch
Control card.
3.3.1 Switch Control Card Redundancy
In a typical Packet Voice Processor configuration, the two Switch Control cards in the
shelf operate in redundant mode. Provisioning for the OOB signaling port using the
command line interface is applied to both OOB signaling ports on the 2 Switch
Control cards (active and redundant), but only the active Switch Control card’s port
is operational at any point in time.
The two Switch Control card’s OOB signaling ports are also both connected to a
router, possibly via a layer 2 switch. The Packet Voice Processor’s redundant Switch
Control card configuration offers protection against a cable cut, port failure, or Switch
Control card card failure by switching over to the protection Switch Control card.
If the customer configuration includes multiple routers, each Switch Control card
could also be connected to a different router to further increase reliability. An
additional mechanism (based on ARP messages) could be used to validate
connectivity and cause a Switch Control card switchover, in addition to the
switchover criteria described in the paragraph above.
In this redundant configuration with multiple routers, ARP messages are sent every
x seconds to a user defined IP device. To set up this redundant configuration, the
Next Hop IP Device parameter (see Table 3-4 on page 39 ) is provisioned with the IP
address of a session border controller, proxy server, or router. Failure for this IP
device to get a response after a certain number of attempts would cause the Packet
Voice Processor to failover to the protection Switch Control card in an attempt to
restore connectivity.
Table 3-4 OOB Signaling Port Provisioning
Step Task Description
1 Access the Packet Voice Processor
system. Establish a connection to the active Switch Control card.
The process for connecting to the management port is
described in
Section 2.2, “Connecting to the PVP”, on
page 23 .
2 Enter the INTERFACE [SHOW]
command. Enter this command to to view the factory created
signaling port name, as well as its current status (in-
service or out-of-service).
See Section 10.2.1 on page 115 for additional
command information.
3 Enter the INTERFACE <sig-port>
[SHOW] command. Enter this command to view the current OOB signaling
port’s configuration. Most of the displayed parameter
values will be set to 0.
See Section 10.4.1 on page 121 for additional
command information.
4 Enter the INTERFACE <sig-port> IP
ADD command. Enter this command to begin provisioning the OOB
signaling port parameters.
See Section 10.4.4 on page 123 for additional
command information.
5 Enter the INTERFACE <sig-port>
SET command. Enter this command to continue provisioning the OOB
signaling port parameters.
See Section 10.4.2 on page 123 for additional
command information.
