Converting simplex bearer to duplicated bearer on
IP-PNC
port networks (with S8700-series Media Servers
only)
Introduction
This module describes the procedures to convert an Internet Protocol port network connectivity
(IP-PNC) configuration from simplex bearer reliability to duplicated bearer reliability. The PNs
are controlled by a pair of S8700 series media server. All voice and data transmission between
the PN you are converting and other PNs in the network occurs over the customer's LAN/WAN.
If the active media processor, or connections to it, fail, active connections failover to the standby
media processor and remain active. This duplication prevents calls from being dropped in case
of failure.
Note:
Only two TN2602AP circuit packs are allowed per port network.

CAUTION:
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.

These conversion procedures assume that the S8700 series media servers are

running release 3.1 or later of Communication Manager. If not, the media servers
must be upgraded to release 3.1 before starting the conversion procedure. To
upgrade the media servers, see the appropriate upgrade module in this book.
Duplicated control network
These procedures apply whether or not there is also an existing duplicated control network.
Avaya strongly recommends a duplicated control network be configured prior to or along with
the conversion to duplicated bearer. Though existing connections may continue during most
failures to the port network, no new connections can be made if the control network is part of the
failure.
