Vibration
The M5216 ACD Set was designed to work to specifications after being
subjected to the following vibrations in each of three orthogonal directions
for 90 minutes:
• Vibration frequency of 5 Hz to 500 Hz
• Maximum half displacement 0.35mm (0.014 in)
• Maximum acceleration 1.5m/s/s.
In addition, the design of the set accommodates normal handling during
shipment when it is contained in its packaging.
Shock When packaged, the M5216 is designed to withstand normal handling during
shipment.
When unpacked, the M5216 is designed to withstand accidental dropping
during normal use, without sustaining damage, as specified below:
• Telephone: when dropped on any face or corner from a height not
exceeding 0.75m (30in)
• Handset: when dropped from a height not exceeding 1.5m (60in).
Line engineering
The M5216 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 DMS-100
Business Set Line Engineering, NTP 297-2011-180. The maximum loop
length is 4,572m (15,000 ft) on 26 AWG standard twisted pair telephone
wires.
The interface to the Central Office (CO) equipment is through a business set
line card in the Line Concentrating Module (LCM) of the DMS–10/DMS–
100/Meridian SL-100 Central Office (CO) equipment.
Loop power The M5216 is partially loop powered by a balanced 440 Ohm battery feed
from the switching equipment. The switch battery voltage supplied to the
loop is nominally 52 VDC with a minimum of 42.75 VDC and a maximum
of 56 VDC. Under normal conditions the polarity must be negative on the
Ring lead with respect to the Tip lead.
