Switchboard Function
Definition
The control station (= exchange station) manually establishes a connection between two intercom
stations.
General
Any intercom station can be connected to any other intercom station by the control station operator
(controlled communication).
In most situations, a two-way direct communication link to the control station is sufficient. In some events,
for example during maintenance shutdowns, it may become necessary for certain intercom stations to
communicate with each other. The switchboard function has been designed to meet this demand.

Description
The switchboard function enables control stations to connect intercom stations which don’t have a
connection provided in the intercom connection diagram.
The maximum number of concurrent connections is limited to 4 (= 4 channels).
The control station must be equipped with a numerical keypad. A direct dial key for each station requiring
a connection as well as a “channel select” key and a “channel delete” key for each channel must be
programmed.
The intercom stations must have a direct dial key to the control station and a “talk-back key”.
Example
Step 1
Station A requires a connection to station B. The user informs the control station operator accordingly.
Step 2
The connection is established as follows:
Control station:
• Press the “channel select” key
• Enter station A‘s number via the numerical
keypad
• Press the talk key *
• Enter station B’s number via numeric keypad
• Press the talk key *
• Press the “channel select” key
• “Channel select” key LED on (visual signal)
Step 3
Intercom station:
• “Talk-back key” LED on station A is flashing
• Communication between stations A and B via “talk-back key”
• Visual status signals: LED at active station on, LED at passive station is flashing
Termination:
• Station A or B informs control station operator that connection is no longer needed
• Control station operator terminates the connection by pressing the “channel delete” key
