Converting some or all CSS port networks
to IP-PNC
Introduction
This module describes how to convert one or more port networks (PNs) with fiber port network
connectivity (fiber-PNC) using a center stage switch (CSS) to Internet Protocol port network
connectivity (IP-PNC). An S8700-series Media Server controls the PNs.
This conversion changes the transmission of inter-PN bearer traffic from circuit-switched
protocol over fiber connections to packet-switched IP over Ethernet connections.
!
Important:
The S8700-series Media Servers must be running release 3.0 or later of
Important:
Communication Manager before you start the conversion procedure. To upgrade
the media servers, see the appropriate upgrade module in this book.
These procedures do not change the cabinet hardware as part of the conversion. All MCC1,
SCC1, and G650 cabinets in the starting multiconnect configuration are present in the
converted IP-PNC configuration.
Note that for CSS starting configurations, the switch node carrier cannot be used in the
converted configuration unless the carrier remains fiber-connected.
The starting configuration
The starting configuration consists of Fiber-PNC PNs that use a CSS. All PNs are Fiber-PNC
through the CSS and one or more PNs are IPSI-connected to the control network.
For Communication Manager release 3.0 and later, the starting configuration can include some
IP-PNC components in addition to the fiber-PNC components. Each PN can be implemented in
an MCC1, an SCC1 stack, or a G650 stack. The overall system can be any combination of
MCC1, SCC1, or G650 gateways.
The reliability level of the starting configuration can be:
Duplex: Duplicated media servers, the standard reliability for S8700-series Media Servers
High: Duplicated media servers and control network, available for S8700-series Media Servers
only
Critical: Duplicated media servers, control network, and bearer network, available for
S8700-series Media Servers only
