Connectivity for more information.
■ Point-to-Point Protocol (PPP) data module. Refer to DEFINITY ECS
Administration for Network Connectivity for more information.
NOTE:
The 51X series Business Communications Terminals (BCTs) are not
administered on the Data Module screen. The 510 BCT (equivalent to a
7405D with a display and built-in DTDM), 515 BCT (equivalent to a 7403D
integrated with 7405D display module function, data terminal and built-in
DTDM), and the 7505D, 7506D, and 7507D have a DCP interface but have
built-in data module functionality. Both are administered through the Station
screen.
Detailed description of data modules
TTI allows data modules without hardware translation to merge with an
appropriate data module connected to an unadministered port. The
unadministered port is given TTI default translation sufficient to allow a terminal
connected to the data module (connected to the port) to request a TTI merge with
the extension of a data module administered without hardware translation.
NOTE:
TTI is not useful for Announcement and X.25 hardware.
Administration Without Hardware supports PDM, TDM, Data-Line,
Announcement, and X.25 data modules.
NOTE:
The 513 BCT has an EIA interface rather than a DCP interface (no built in
data module, attachable telephone, or telephone features). The 513 BCT is
not administered; only the data module to which the 513 BCT is connected
is administered.
7400A/7400B+/8400B+ Data Module
Use the 7400A data module instead of an MTDM when you support combined
Modem Pooling. The 7400A data module supports asynchronous operation at
speeds up to 19200-bps, and provides a DCP interface to the switch and an EIA
232C interface to the associated modem. The 7400A operates in stand-alone mode
as a data module.
7400B+ and 8400B+ data modules support asynchronous-data communications
and operate in stand-alone mode for data-only service or in linked mode, which
provides simultaneous voice and data service. The 7400B+ and 8400B+ provide
voice and data communications to 7400D series phones and 602A1
