External Power Straps
Digital telephones equipped with options such as integrated data interface units and ADMs require
two-pair wiring or external power to operate efficiently at the maximum-allowed distance from the
KSU. Two-pair wiring or external power is also necessary for maximum cable run lengths for digital
telephones that are connected to systems that must operate with reserve power (see
for more information).
Each digital telephone has two external power straps which must be cut for external power when the
cabling of the telephone is connected to an external AC/DC power supply.
➤
To cut the straps
1. Loosen the four captive screws on the telephone base and remove the base.
2. Depending on the telephone, locate the W101 and W102 external power straps and cut them.
3. Reinstall the telephone base, and secure it with its four captive screws.

information and installation instructions.
