Installation Procedures
Follow the steps for the proper configuration to install the ISDN
7500B Data Module.
Stand-Alone, Single-Port Asynchronous DCE Configuration.
This configuration uses the basic ISDN 7500B Data Module (see
Figure 35):
1. Remove the 7500B from the box.
2. Plug the D8W cord into the jack labeled LINE on the back of
the 7500B.
3. Plug the WP90110,L1 power supply cord into the connector
labeled POWER on the 7500B.
4. Plug the male end of the EIA-232D cable into the connector
labeled PORT 1.
5. Connect the other end of the EIA-232D cable to the data
terminal.
Plug the other end of the D8W cord into a telephone wall jack
6.
or into a 440A4 terminating resistor adapter (when the 7500B
is installed without an MLX telephone).
7. As necessary, plug the terminating resistor adapter into the
wall jack.
8. Plug the power cords of the WP90110,L1 power supply and
the data terminal into an AC power outlet that is not controlled
by a wall switch.
