Environmental And Safety Considerations; Line Engineering - Northern Telecom M5212 ACD General Description, Installation And Maintenance

Environmental and Safety Considerations

The M5212 meets the Canadian and U.S. mandatory interconnect
requirements for telephone equipment.
Temperature and Humidity
The M5212 operates within the following conditions:
•
•
Electromagnetic Interference
The radiated and conducted electromagnetic interference meets the
requirements of Subpart J or Part 15 of FCC rules for class A computing
devices.
Vibration and shock
The M5212 ACD Set was designed to continue to work to specifications
after being subjected to the following vibrations in each of three orthogonal
directions for 90 minutes:
•
•
•
In addition, the design of the set accommodates normal handling during
shipment when it is contained in its packaging.

Line Engineering

The M5212 ACD set is designed for direct connection through a non-loaded
subscriber loop pair to a Northern Telecom DMS-100 or DMS-250 Digital
Switching system. It operates to its full potential through twisted pair
wiring on transmission lines selected according to rules detailed in NTP
297-2011-180, DMS-100 Business Set Line Engineering. The maximum
loop length is 4,572 m (15,000 ft) on 26 AWG standard twisted pair
telephone wires.
The interface to the Central Office (CO) equipment is through a business set
(6X21AC) line card in the Line Concentrating Module (LCM) of the
