Problems are typically localized and do not affect
other units. Hardware maintenance and repair proce-
dures describe how to quickly locate, remove, and
replace defective modules.
System programming can be performed without
taking the system out of service. On-site program-
ming can be executed with any 20-button proprietary
LCD (liquid crystal display) telephone, or with an
ASCII terminal connected to an optional maintenance
port. Off-site programming—which can help cut costs
and save time—is available through an optional
modem.

The main building blocks of each system are cabi-

DK8 consists of a single Key Service Unit (Figure 2).

Key Service Unit (Figure 4). Every central office (CO)
line, station, and peripheral connects to these units.
The STRATA DK8 Key Service Unit comes
equipped to interface with up to four Toshiba-propri-
etary digital telephones and two CO lines. It can be
