Digital telephones equipped with options
such as Integrated Data Interface Units and ADMs
require two-pair wiring or external power to oper-
ate efficiently at the maximum-allowed distance
from the key service unit (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 re-
serve power. (See Table 8-D in Section
l OO-816-
208 for reference.)

straps which must be cut for external power when
the cabling of the telephone is connected to an
external AC/DC power supply. Cut these straps in
