Introduction
297–2011–214 02.01 Standard February 1999
General description
The M5316 Meridian Business Set is designed for direct connection (through
a non-loaded subscriber loop pair) to the Northern Telecom DMS–10,
DMS–100, DMS–250, or Meridian SL–100 Digital Switching systems.
The M5316 is partially loop powered and requires the use of a 16 V AC
external power supply.
The service provided by the M5316 substitutes low-level signals over a half-
duplex, above-voice band (8 kHz) signalling channel for the traditional loop
signalling (dial pulse) or inband tone signalling (DTMF tones) on a
conventional subscriber loop. In addition to signalling and supervision,
messages on the above-voice band signalling channel include signals for
implementing the many special features available on the M5316, as well as
display characters.
The M5316 offers a choice of selected key and system features—it has 3
fixed keys, a dial pad consisting of 12 fixed keys, 16 programmable
feature/directory number keys with LCD indicators (including the two
assigned feature keys Handsfree and Mute), and is equipped with a speaker
for alerting tones, Handsfree dialing and intercom.
The alphanumeric display module is mounted at the rear top edge of the
telephone and is hinged so that the viewing angle can be adjusted physically
to reduce glare and maximize the contrast. The maximum display capacity
of the display screen is 2 rows of 24 characters each.

1-2 Introduction
297–2011–214 02.01 Standard February 1999
Physical characteristics
Figure 3-1 shows the main components of the M5316. The M5316 comes in
three different colours:
• Chameleon-grey (Engineering code NT4X42AA)
• BTS light-grey (Engineering code NT4X42BA)
• Black (Engineering code NT4X42CA)
The Mean Time Between Failure (MTBF) for the M5316 is at least 100
years.

Specifications
297–2011–214 02.01 Standard February 1999
The following specifications govern the performance of the M5316 Business
Set and the environmental conditions under which this performance is
achieved.
Environmental and safety considerations
The M5316 meets the Canadian and U.S. mandatory interconnect
requirements for Telephone Equipment, CSA, DOC, UL, FCC (part 15 &
part 68).
Temperature
In the Operating State, the M5316 temperature range is 0 C to 50 C
(32 F to 122 F).
In the Non-Operating State, the M5316 temperature range is -20 C to 70 C
(-6 F to 158 F).
Relative humidity
20% to 95% (non-condensing). At temperatures above 34 C (93 F), relative
humidity is limited to 52mbar of water vapour pressure.
Electromagnetic interference
The radiated and conducted electromagnetic interference meets the
requirements of Subpart J of Part 15 of the FCC rules for class B computing
devices.
Atmospheric pollution
The M5316 is designed to withstand normal atmospheric conditions
throughout its life and during shipment and storage as defined in the
International Electromechanical Commission (IEC) document 50 (salt, mist,
atmospheric dust, sulfur dioxide, and hydrogen sulfide exposure).

2-2 Specifications
297–2011–214 02.01 Standard February 1999
Vibration
The M5316 is 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.
Shock When packaged, the M5316 is designed to withstand normal handling during
shipment.
When unpacked, the M5316 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 M5316 operates to its full potential through twisted pair wiring on
transmission lines selected by the rules provided in NTP 297–2011–180.
The M5316 interfaces with the business set (6X21AC) line card in the Line
Concentrating Module (LCM) of the DMS–10/DMS–100/Meridian SL-100
Central Office (CO) equipment. The 6X21AC supports one business set per
line card.
Loop power The M5316 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.
The current drawn from the loop is 16 ±1mA when the set is active. The
current drawn from the loop is 10 ±1mA when the set is inactive.
External power
The M5316 requires a 16 V AC external power supply rated at 375 mA.
During a power failure, the Handsfree and RT clock functions are not
available.
