Data Communications Support
Video Conferencing Application
This section shows an example of how to connect a 7500B Data Module with a
multipurpose enhancement board for synchronous data communication, which
allows data transmission at the speed of 56 or 64 kbps.
High-Speed Synchronous Enhancement Board
For instructions on using a high-speed synchronous enhancement board or any
information on setting up the 7500B Data Module, not included in this section,
see the documentation packaged with the 7500B Data Module,
This section is intended only as a guideline for connecting video conferencing
equipment to the system. For any additional information, see the documentation
packaged with the video codec.
Hardware Requirements
008 MLX or 408 GS/LS-MLX module in the control unit
ESF T1 CSU
NOTE:
If any other type of CSU is used, your customer support organization
cannot support installation and maintenance.
Two Shore Microsystems SM-100 EIA-232/V.35 converters (or equivalent)
Two 7500B Data Modules
Two 7500B Data Module feature package 2 upgrades (user's manuals
included)
Two multipurpose enhancements boards. By installing a multipurpose
enhancement board in each 7500B Data Module, you can provide
synchronous communication and RS-366 ACU interface.
Two WP901 10-L7 power supplies (one per standalone 7500B Data
Module)
Two 440A4 terminating resisting adapters
Z77A multiple mounting (mounting for multiple 7500B Data Modules)
Cables:
— Two male/male EIA-232-D cables, 8 feet (24 meters), to connect
— Two male/male V.35 DB-37 cables, 8 feet (24 meters), to
— Two male/male RS-366 DB-25 cables, 8 feet (24 meters), to
the PORT 1 jacks on the data modules to the EIA-232/V.35
converters
connect the V.35 communication ports on the video codec to the
EIA-232/V.35 converters
