Specifications.
These specifications provide necessary information concerning the operation and interface requirements
for the LIU module. This list is intended as a source of reference, and is not meant as a strict list of
compliance requirements.
•
EIA/TIA RS-470-A (North American Analog Telephone Interface Requirements)
-
defines
interface requirements for telephone devices. Document is a reference showing performance
ranges of most high-quality analog telephone devices.
•
EIA/TIA RS-464-B (PBX Interface and Operation Requirements)
-
defines the interface and
operational requirements for Private Branch Exchange switches. The analog interface between
these systems and analog telephone devices is a subset of this specification.
•

2.4.
Power Supply Module (PSM).
The Power Supply module receives unregulated power from the Battery Management module, and then
provides the necessary regulated dc outputs required to operate the other circuitry within the LAU. The
PSM also contains the unit’s three Status Indicators. The specific requirements of this module are
defined in detail below.
2.4.1. Functional
Characteristics.
There are no special functional requirements for the Power Supply Module.
2.4.2. Electrical
Characteristics.
