The rear transition module for the CP5370 Host Central Processing

Unit (CPU) card contains the following:

• COM2 port for connection to a terminal server and local monitor.

• Two Ethernet ports which provide connectivity to the Private

Network. The connection carries signaling and OAM data.

— The Ethernet 1 port is always used to provide an active

connection.

— The Ethernet 2 port provides a standby connection. The standby

ethernet function is enabled by default through the “Activate IP

Failover” property when configuring the RTP Media Portal. (See

Table 2, “RTP Media Portal tab configurable properties,” on

page 33.)

These Ethernet connections carry the following:

• MGCP+ signaling to communicate with the SIP Application Module.

• operations, administration and maintenance (OAM) data to the

Management Module.
