each line) single-pair modular cords or a
single 3-pair modular cord (STRATA Se); or
two 3-pair or six single-pair modular cords
(STRATA Vie).
b) The station connection points are extended
from the key service unit to the main distribution frame using 3-pair modular line cords.
The individual telephones are connected to
the main distribution frame using 3-pair station cables.
c) A screw-terminal barrier strip is mounted on
the left-hand side of the key service unit to
provide attachment points for the music-onhold source input, relay service (STRATA Vle
only) and external page output.
d) Two (only one for STRATA Se) modular con-
nectors are also provided on the left side
panel for two (only one for STRATA Se) op-
tional off-premises line modules (HOLBs).
The power supply is mounted inside the key
service unit. In STRATA Se a connector is provided on the left side panel for optional system
reserve power (HPFB). In STRATA Vle an op-
tional battery backup printed circuit board is
available for the power supply.
Maintenance
Faults in the system are repaired by replac-
ing any faulty component (printed circuit board,
subassembly, telephone, etc.) and returning it to
the manufacturer for repair.
In addition, remote administration/
maintena-rice allows the system to interface via
an SDTU (built-in modem) with a remote loca-
tion. This reduces the cost of routine data base
changes by eiiminaring the need of a technician
to be ?n-site for each software change.
