The analog voice and modem data station requires a bridging adapter to
connect the telephone to the two adjacent analog extension jacks.
The 7500B data-only station requires a terminating resistor adapter to
connect the 75006 data module to the MLX extension jack.
See “Video Conferencing Data Stations,” later in this chapter, for
configuration details on stations including video codecs.
The cord length from the 7500B data module to the telephone cannot be
more than 80 ft. (24 m).
Do not connect two

7500B data modules on one line.
A modem data station uses a modem to convert digital signals so that it can
send and receive analog signals. This type of station allows data
communication without PRI facilities.
The system supports the types of modem data stations listed below.
Analog Voice and Modem Data.
This station includes a data terminal
and an analog multiline telephone.
Modem Data-Only.
This station includes a data terminal and modem.
If this station’s modem has a phone jack, you can connect a single-line
telephone; however, voice and data at the same time are not possible.
MLX Voice and Modem Data.
This station includes a data terminal,
modem, and an MLX telephone.
See Form 2a, System Numbering: Extension Jacks for your customer’s
specifications. Then refer to the appropriate section later in this chapter for
instructions on setting up modem data stations.
