Performance specifications

Environmental and safety considerations

All Meridian modular telephones and their associated options meet the
requirements of Electronics Industries Association (EIA) specification
PN-1361.

Temperature and humidity

Table 4-1 lists temperature and humidity specifications for Meridian
modular telephones.

Temperature and humidity specifications

Temperature range
Operating state:
32 to 104 F (0 to 50 C)
Storage:
–58 to 158 F (–50 to 70 C)
Note 1: At temperatures above 93 F (34 C), relative humidity is limited to 52
mbar of water vapor pressure.
Note 2: Meridian modular telephones should be stored at the maximum and
minimum temperatures for no longer than 16 hours.

Electromagnetic interference

The radiated and conducted electromagnetic interference meets the
requirements of Subpart J of Part 15 of the Federal Communications
Commission (FCC) rules for Class A computing devices.

Line engineering

The Meridian modular telephones use twisted pair wiring on transmission
lines. The maximum permissible loop length of the MSL-100 digital line
circuit is 3,500 feet (1067 meters), assuming 24 AWG (0.5 mm) standard
twisted wire with no bridge taps. A 15.5 dB loss at 256 kHz defines the loop
