51-04-01 : IP Address for Top Priority Primary System – Internet Protocol

Address for Top Priority Primary System
Enter the IP address of the Primary SV9100. This setting is needed to use the
Primary SV9100 Automatic Integration Feature (Program 51-06-01). If the
secondary flag is set in Program 51-01-03 secondary SV9100s connect with
this IP address.
10-12-09 : GCD-CP10 Network Setup – VoIP Daughter Board IP Address

Set the LAN IP address for the VoIP daughter board. The IP number increases
by one for each increase in the slot number.

51-09-01 : NetLink TCP Port Settings – Primary Port

Define the port the Primary SV9100 uses to communicate with the Secondary
SV9100 (0~65535).
51-09-02 : NetLink TCP Port Settings – Communication Port

Define the port used to communicate between other networked communications
servers (0~65535).
51-09-03 : NetLink TCP Port Settings – Secondary Port

This setting defines the port used by the Secondary SV9100 to communicates
to the Primary SV9100 (0~65535). If 0 is entered, the port is selected
dynamically.
51-09-04 : NetLink TCP Port Settings – Primary Search Port

When Fail-Over occurs, each SV9100 communicates with the other
communication servers using the port number specified in this entry (0~65535).
If 0 is entered, the port is selected dynamically.
If an entry other than 0 is made, up to 50 ports (depending in the number of
networked systems) are continuously used from the specified port number. (Ex:
If 5000 is entered, 5001~5049 are used.)
The system ID for each communication server must be unique. Otherwise, the
connection is refused. The information for the refused connection is included in
the communication server alarm report.
If a communication server loses connection and another communication server
with the same ID then tries to connect to the NetLink, it is recognized as the first
communication server (which lost the connection) and is allowed to connect.
If a Secondary System loses connection, it does not affect the operation of the
Primary System.
51-18-01 : NetLink Fail-Over Limit

When tear-down of network is repeated more than the specified times, NetLink
is operated in stand-alone. Input range is 0, 2~10 (0 = Infinity). Default is 0.
Conditions
When the Primary System is switched, all terminals and blades are reset so the

change of the Primary System can be made. This process takes approximately
30 seconds.
When Fail Over occurs between the Primary System and two or more

Secondary Systems, the attendant telephone displays the System ID of the
system that went into Fail-Over last.
