Connections

All DP5000-series telephones with no ADM connected should use the standard, one-pair (two-wire) line
cord included with the telephone.
Digital telephones connect to the MDF with standard twisted-pair telephone wiring. In most cases digital
telephones can operate at up to 1000 feet when using a single pair, 24 AWG cable from telephone to
equipment cabinet. Refer to Table , "Station Loop Lengths," on page 11.
Digital telephones equipped with one or more ADMs require two pairs of wire, from the system to the
station, to operate at maximum cable length. All digital telephones connected to systems with reserve
battery power, regardless of cable length, should use two-pair cable.
The telephone wiring must be terminated at a modular station connect block (RJ11). The standard line
cord, sent with each station is seven feet long. The maximum length line cord allowed is 25 feet.
Digital telephone cable runs must not have:
• Cable splits (single or double)
• Cable bridges of any length
• High resistance or faulty cable splices
The DP5000-series handset connects with a two-pair modular cable included with the telephone.
An ADM connects to the DP5000-series station only with the modular cable included with the ADM.
