Data features for host or terminal applications include:
■ EIA RS-232-D DCE interface
■ Keyboard dialing and Hayes user interface emulation option
■ Answer only
■ Cyclic Ring-indicator option
■ Ignore DTR input option
Power
The stand-alone 7400A data module operates with power from a WP90110 L7 AC
power converter. This is a modular AC to DC adapter that is normally plugged into
a wall outlet. The Z77A Data Mounting has a built-in power supply for powering
data modules in the multiple-mount arrangement.
Considerations
The 7400A data module will NOT support the following:
■ Linked operation with associated DCP telephone
■ Synchronous Data transmission
■ Asynchronous User Interface (AUI)
■ DCP Mode 0, 1, 3, and Mode 2/3 adaptive
FCC Registration
No digital phones or data modules are FCC registered. The 7400A data module
meets Part 15 Class A requirements and is labeled as such.
