SBX IP 320 Features & Operation Guide
Net Call
Net Call allows a Station User to make a call to a Station in another Networking System by
dialing a Station number just as an intercom call would be dialed within the same System.
Note:
During a conversation, all telephony features are available (e.g., call transfer, hold,
conference).
Operation
To make a Net Call:
1.
Lift the handset or press the [SPEAKER] button; the dial tone sounds.
2.
Dial a Station number on another Networking System.
-or-
Press the [NET DSS] button.
3.
The station will access a Network CO Line according to the Net Routing Table; the
System will send a digit stream that is modified by the Net Routing Table.
4.
The called System will receive a digit stream that is sent by the calling system, and will
analyze it using the Net Routing Table to determine the right destination Station.
5.
The call will ring at the destination Station.
6.
The [COL] flexible button LED representing the CO line for the Net Call, will extinguish
when the Net Call is completed.
Conditions
•
To make a Net Call, as an Intercom call, the Station User must dial the destination Station
number without seizing a CO line.
•
After the Station User makes a Net Call, the SBX IP 320 system will access an idle CO
line to send the Net Call request to the destination Station. If there is no selectable idle
CO line, then the User will receive an error tone.
•
A received Net Call will ring in the Terminal Answer Mode, regardless the Intercom
answer mode setting (Hands-free/Terminal/Privacy).
•
When system detects a fatal error from the Network, the System will send the digit
stream to the Network using the alternate speed dial bin. In this case, the Call is not a
Networking Call.
•
The Net Call is also applied to the CO Call Restriction Timer (PGM 180 - FLEX 17).
