268 Hardware Description and Reference for Avaya Communication Manager
The TN2602AP IP Media Resource 320 circuit pack has two capacity options, both of which are
determined by the license file installed on Communication Manager:
● 320 voice channels, considered the standard IP Media Resource 320
● 80 voice channels, considered the low-density IP Media Resource 320
Only two TN2602AP circuit packs are allowed per port network.
Note:
Note: The TN2602AP IP Media Resource 320 is not supported in CMC1 and G600
Media Gateways.
Detailed description
Load balancing
Up to two TN2602AP circuit packs may be installed in a single port network for load balancing
The TN2602AP circuit pack is also compatible with and can share load balancing with the
TN2302 and TN802B IP Media Processor circuit packs. Actual capacity may be affected by a
variety of factors, including the codec used for a call and fax support.
Note:
Note: When two TN2602AP circuit packs, each with 320 voice channels, are used for
load balancing within a port network, the total number of voice channels available
is 484, because 484 is the maximum number of time slots available for a port
network.
Bearer duplication
Two TN2602AP circuit packs may be installed in a single port network (PN) for bearer
duplication. In this configuration, one TN2602AP is an active IP media processor and one is a
standby IP media processor. If the active media processor, or connections to it, fail, active
connections failover to the standby media processor and remain active. This duplication
prevents active calls in progress from being dropped in case of failure. The interchange
between duplicated circuit packs affects only the PN in which the circuit packs reside.
Note:
Note: The 4606, 4612, and 4624 telephones do not support the bearer duplication
feature of the TN2602AP circuit pack. If these telephones are used while an
interchange from active to standby media processor is in process, calls may be
dropped.
