3.4.4 Connecting the RS-232 Serial Interface
The RS-232 interface can be used for local configuration using Command Line Interface
(CLI). For a description on accessing the CLI using the RS-232 interface, refer to Section
'RS-232 Interface' on page 68.
¾ To connect the MediaPack's RS-232 interface, take the following
step:
Using a standard RS-232 straight cable (not a cross-over cable) with DB-9
connectors, connect the MediaPack's RS-232 port (labeled RS232) to either the
COM1 or COM2 RS-232 communication port on your PC.
The required connector pinouts and gender are shown below in Figure 3-9.

3.4.5 Connecting the Lifeline Port
To implement the Lifeline feature, port S/T 0 must be configured as network port. When a
power outage occurs, the lifeline phone (connected to port S/T 0) can continue making
calls (although this time, through the PSTN network, not the WAN).
¾ To connect the Lifeline port:
1. On the MediaPack's rear panel, connect the ISDN telephone to S/T port (labeled S/T
O).
2. On the MediaPack's rear panel, connect the PSTN network to the lifeline port (labeled
Lifeline).
