Modem links in SIGMANET

Modems can be used to bridge longer distances.
Two types of modem exist:
Baseband modems can only be used for galvanic connections
Voice band modems can be used irrespective of the line type.
Please note the following when using a modem:
•
Up to eight modem links can be set up in SIGMANET.
•
A maximum of 16 SIGMANET units are permitted when starting a modem.
•
Apart from at the SIGMANET control panel (S24230-F130-A4), the modem must be
connected to a TTY/V24 converter.
•
The TD-32B-DC voice band and BMXtra voice band modems must only be operated in
systems where all SIGMANET units have firmware version 3.1.
•
All modems must be powered by the control and indicating panel's PSU.
•
The maximum possible connection length depends on the line type.
