408 GS/LS-MLX
module set as a
2B Data port, or 2
jacks set as 1B
Data ports †
*
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 administered 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 use Version 28 of the module.
