The maximum length of cable between the Rack
and the DEFINITY ECS is 500 ft (150 meters).

q

 

The Rack’s power supply and cabling should be
installed away from high power/high RF noise
devices such as computers, fans, fluorescent ballast,
power supplies, etc.

q

 

Use good wiring practices. Do not run wires over
fluorescent lights, computers, air conditioners, etc.
as this can introduce noise to the modems.

The Rack must be installed in a secure location.
Unauthorized access to the Rack could lead to toll
fraud.
