Converting IP-PNC port networks with simplex
control to
duplicated control
Introduction
This module describes the procedures to convert one or more IP-PNC port networks with a
simplex control configuration to a duplicated control configuration. The PNs are controlled by a
pair of S8700 series Media Servers.
Note:
Duplicated control networks are not supported on the S8500 Media Server.
Note:
This conversion adds a second TN2312BP IPSI circuit pack to an IP-PNC port network and a
second Ethernet switch, if necessary, for connections between the servers and the IPSIs.
If the port network consists of SCC1 or MCC1 Media Gateways, cabling of the IPSI circuit pack
to a TN775 Maintenance circuit pack is required. If the port network consists of G650 Media
Gateways, the TN775 Maintenance circuit pack is not used, and, therefore, there is no cabling
to a TN775 circuit pack.
Preconversion assumptions
The conversion procedures in this chapter assume that:
You have completed the pre-site checklist,
●
the customer site.
The system has been upgraded to Communication Manager release 3.0 or higher. With
●
release 3.0 or higher, you can add duplicated control for individual IP-PNC port networks.
For earlier releases, all port networks had to have the same reliability level, which meant
that you had to add duplicated control to all IP-PNC port networks.
