Converting simplex bearer to duplicated bearer on IP-PNC port networks (with S8700-series Media Servers
Overflow with coresident TN2302AP circuit packs
If you anticipate that at peak traffic periods, traffic on the port network will exceed the maximum
administered VoIP channels, 80 or 320, of the TN2602AP circuit pack, a TN2302 may be
coresident. Communication Manager will pass excess traffic over the TN2302 at peak traffic
periods, but these calls will not be supported by the duplicated reliability.
Reduced channels with duplicated TN2602AP circuit packs
If a pair of TN2602AP circuit packs previously used for load balancing are re-administered to be
used for bearer duplication, only the voice channels of whichever circuit pack is active can be
used. For example,
If you have two TN2602 AP circuit packs in a load balancing configuration, each with 80
●
voice channels, and you re-administer the circuit packs to be in bearer duplication mode,
you will have 80 (not 160) channels available.
If you have two TN2602 AP circuit packs in a load balancing configuration, each with 320
●
voice channels, and you re-administer the circuit packs to be in bearer duplication mode,
you will have 320 (not 484 — see the note that follows) channels available.
Note:
When two TN2602AP circuit packs, each with 320 voice channels, are used for
Note:
load balancing within a port network, the total number of voice channels available
is 484, not 640, because 484 is the maximum number of time slots available for
connections within a port network.
Prerequisites
This section itemizes the information and materials you must have, and the tasks you must
perform, before you can start the conversion procedure. The conversion procedure in this
chapter assumes that:
The port network is an IP-PNC configuration, which means that there are no fiber links to
●
other port networks. If not, you must first convert the port network from fiber-PNC to
IP-PNC. If necessary, see one of the following:
- Converting some or all direct-connect port networks to IP-connect
- Converting some or all CSS port networks to IP-PNC
- Converting some or all ATM port networks to IP-PNC
