General Description of Product.
The Maxon J-STD-008 Line Access Unit (LAU) is an J-STD-008 compatible transceiver unit which
provides an interface between a standard EIA-470 compliant telephone-type device and a J-STD-008
CDMA PCS base station.
1.1.
Basic Features and Design Requirements of Product.
The following general requirements will be provided by the Maxon J-STD-008 LAU.
Electrical
Main Power Source:
Country-specific ac/dc wall transformer, with input
voltages between 90 - 280 Vac, 50-60 Hz, and an
output dc voltage of 16 - 30 Vdc (nominal
∼
19 Vdc).
Reserve Power Source:
Sealed-cell lead acid battery,
∼
12 V, rechargeable,
with sufficient capacity to provide up to 1.5 hours
TALK time and up to 22 hours STANDBY time, when
measured from a condition of full charge, at an
ambient temperature of 25
°
C.
Battery Recharge Time:
The recharge system will provide sufficient capability
to fully recharge the reserve battery from maximum
allowable discharge to maximum charge level in less
than 36 hours.
Surge Protection:
Product will meet the requirements of paragraph
4.2.7.4.5. of EIA/TIA-571, for Type 2 surges.
RF Transmitter Power (maximum):
200 mW, measured at antenna connector.
Antenna Interface:
50 ohms
Power Fuse:
Internal, not accessible by the customer..
Mechanical
Shock:
The unit shall be designed to withstand the drop
requirements of EIA/TIA-571, paragraph 4.1.1.1.3.-
3.a., which specifies single face drops from 6” and
single corner drops from 3” onto a tiled surface, with
battery installed.
Vibration:
Required to survive typical transportation and shipping
induced vibrations, as defined by paragraph 4.1.1.2. of
EIA/TIA-571, with battery removed. The battery is not
covered by this specification.
