CAUTION
Damage to Equipment
Service Interruption
Use only the line cord provided with the M2000
Series Meridian Digital Telephone. Using a cord
designed for other digital telephones could result in
damage to the cord or a loss of set functionality.
The M2006, M2008, M2008HF, M2616 (basic configuration and with
Display module), and M2216ACD-1 are loop powered. Loop power,
originating in the ISDLC or the DLC, consists of a 30 V dc power source and
assumes a 3500 ft. (1219 m) maximum loop length of 24 AWG (0.5 mm)
wire and a minimum 15.5 V dc at the telephone terminals.
Note: The loop length limit is defined by a 15.5 dB loss at 256 KHz.
Longer lengths can be determined using the wire's gauge and insulation.
