Summary of Data Station Configurations 5
Table 5–1 describes the extension jacks and equipment required for each data
station configuration.
Table 5–1. Data Station Configurations
* An analog telephone may be connected.
† A digital data/video station that connects directly to an MLX port using either a BRI interface
or a v.35 interface and an ISDN terminal adapter that supports 2B Data, requires only one
MLX port programmed as a 2B Data port. A digital data/video station that connects to an
MLX port using a v.35 interface and an ISDN terminal adapter that does not support
2B Data, requires two 1B Data MLX ports. When using the 008 MLX or 408 GS/LS-MLX
module for digital data or video, you must
not
use Version 29 of the module.
