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
