Data Stations
Terminal Adapter Data Stations
A terminal adapter data station uses a 7500B or ExpressRoute data module to
convert MLX voice signals and DTE digital signals to the digital transmission
signaling standard, so that it can send and receive digital signals. This type of
station requires PRI facilities to send and receive data to and from digital data
stations that are outside the system.
The system supports the following types of data stations connected to terminal
adapters:
■ MLX Voice and Terminal Adapter Data. This station includes a terminal
adapter, a data terminal, and an MLX telephone.
■ Terminal Adapter Data-Only. This station includes a terminal adapter,
and a data terminal, but no telephone.
For your customer’s specifications, see Form 2a, System Numbering: Extension
Jacks and Form 2b, System Numbering: Digital Adjuncts. Then refer to the
appropriate section later in this chapter for instructions on setting up terminal
adapter data stations.
NOTE:
A video conferencing data station is a synchronous terminal adapter data
station. Refer to ‘‘
Video Conferencing Data Stations’’ for more information.
