Electromagnetic interference
The radiated and conducted electromagnetic interference meets the
requirements of Subpart J of Part 15 of the FCC rules for Class A computing
devices.
Line engineering
The maximum permissible loop length is 3500 ft. (915 m), assuming 24
AWG (0.5 mm) standard twisted wire with no bridge taps. A 15.5 dB loss at
256 KHz defines the loop length limit (longer lengths are possible, depending
on the wire's gauge and insulation).
The M2016S uses a 6 conductor line cord (A0346862).
Note: Use only the line cord provided with the telephone. Using a cord
designed for other digital telephones could result in damage to the
M2016S.
Local alerting tones
The M2016S telephone provides four alerting tones and a buzz sound. The
system controls the ringing cadence by sending tone-ON and tone-OFF
messages to the telephone. The alerting tone cadences cannot be changed
from the telephone, but can be altered for individual telephones by
software-controlled adjustments.
