Modem Pool Hardware Requirements

■Modem (one per data module)

Most modems can be connected to the system. If a modem is used in a modem pool, use a 2224G modem. The modem option settings in this section are specifically for this modem.

■7500B data module (one per modem)

■WP90110-L7 power supply (one per standalone data module) or a 277A multiple mounting power supply

NOTE:

You can configure the 7500B as a standalone data module using a WP90110-L7 power supply or set up a multiple-mount arrangement using a 277A multiple mounting power supply. The 277A provides a common power supply for up to eight data modules. Both the power unit and the data mounting require a 115 VAC power outlet. Neither is provided with the data module and both must be ordered separately.

See the 7500B data module documentation for instructions on installing the 277A for a multiple-mount arrangement.

■D8W cords (two per modem-and-data module pair)

■D4BU cords (one per modem-and-data module pair)

■EIA-232-D cables (one per modem-and-data module pair)

■440A4 terminating resistor (one per data module)

See Figure 6-8and the next section, “Setting Up a Modem Pool,” for detailed procedures.
