Video Conferencing Data Stations

To set up the video conferencing configuration, follow the steps below. See Figure 6-6.

1Plug one end of a D8W cord into the LINE jack on each of the 7500B data modules.

2Connect the other end of each D8W cord.

■If Data Form 1 b indicates that you are to install MLX telephones, plug the D8W cords into the MLX extension jacks specified on Data Form 1b, then go to Step 4.

■If Data Form 1b does not indicate that you are to install MLX telephones, plug each D8W cord into a 440A4 terminating resistor.

3Using two more D8W cords connect each 440A4 terminating resistor to the MLX extension jacks specified on Data Form 1b, then go to Step 6.

4Connect the MLX telephones to the 7500B data modules.

a Plug a D8W cord into the LINE jack on each MLX telephone.

b Plug the other end of each D8W cord into the PHONE jack on each 7500B data module.

5Plug each WP901 10-L7 power supply cord into the POWER jacks on the 75006 data modules.

Do not plug the power supplies into the outlets until the end of this procedure,

6Connect each 7500B data module to the video conferencing data station.

a Use the DB-25 cables to connect the PORT 2 jacks on each 7500B data module to the dialing ports in the video codec’s automatic calling unit. See the documentation packaged with the video codec for instructions.

b Use the EIA-232-D cables to connect the PORT 1 jacks on each 7500B data module to the EIA-232/V.35 converters.

c Use the DB-37 cables to connect the EIA-232/V.35 converters to the video codec’s V.35 communication ports. See the documentation packaged with the video codec for instructions.
