Distance Limitations
The maximum allowable distances of a 7303S from the DEFINITY G1, G2, and
G3, the DEFINITY Enterprise Communications System (ECS), System 75, or
System 85 cabinet are shown in the table below.
NOTE:
Range may be extended to 2,000 feet (610m) for 24- or 26-AWG wire by adding local -48
volt DC power in the satellite closet. Power supplies such as the 346A or 329A may be
connected to the fourth pair from the terminals to obtain the increased range. These power
supplies must be within 250 feet of the terminals.
Power Requirements
The 7305S voice terminal is powered by the tip and ring leads. If the 7305S voice
terminal is equipped with the S202A or S102A speakerphone or the 500A headset
adapter, auxiliary power will be required for the adjunct. Refer to the Adjunct
Power section earlier in this manual.
Power Failure Operation
The 7305S voice terminal cannot be used as an emergency station during power
failure transfer conditions.
FCC Registration
The 7305S voice terminal is not FCC registered.
