Description
The MERLIN LEGEND Communications System supports many options for high-
speed digital data transfer over ISDN (Integrated Services Digital Network) and
T1 Switched 56 facilities, or between two extensions on the MERLIN LEGEND
Communications System. To transfer data, you must have an ISDN terminal
adapter or other system-compatible digital communications device connected to
an MLX port.
NOTE:
A communications device may be included in a hardware and software
application, for example, a video system. For more information about digital
data and 2B data, see the Data/Video Reference .
The supported connections for making digital data calls are:
ISDN Primary Rate Interface (PRI)
ISDN Basic Rate Interface (BRI)
T1 Switched 56 lines
An extension that includes a digital data communications equipment (DCE) device
is called a digital data workstation . It may or may not include a telephone, but is
always connected to at least one MLX extension jack. If the DCE includes an
ISDN-BRI interface, it can use the system's 2B Data feature to combine the
B-channels of a single MLX jack. Many group and desktop videoconferencing
systems support 2B data, as do some DCE devices used for data only (not video)
communications. 2B data is described in more detail in
An MLX telephone can be connected to a desktop videoconferencing system that
supports 2B data. This is called a passive-bus MLX telephone .
