SECTION 2
OPTION INSTALLATION DETAILSKEY SYSTEM/HYBRID CONFIGURATION
The systern can be configured to operate as either a
key system or as a hybrid system. Configuration is by
way of a wire strap connected as detailed below and
illustrated in 
Figure 3-6.
The common equipment is shipped from the factory as
a key system (KF). 
To convert operation over to the
hybrid (MF) system, add the strap.
The 
KF and MF designations are equipment type
categories as stipulated in FCC rules and regulations,
Pan 68, and appear as part of the FCC RegistrationNumber on the equipment label. The appropriate
registration number must be reported to the telephone
company at the time of connection along with other
FCC mandated information. Operationally, the hybrid
configuration enables a PBX feature that may incur a
higher monthly tariff to the telephone company. This
feature allows dial access to (automatic selection of)
outgoing lines. The specific system feature that is
enabled by the multifunction (hybrid) configuration is:

POWER FAILURE STATION
CONNECTIONSThe system provides a tip and ring pair connected to
line 1 as an emergency power failure circuit. This
circuit is active during a commercial AC power failure
if an external battery assembly is not installed to
provide battery back-up power to the system. Anindustry standard, single-line telephone, such as a
Comdial model 2500-xx, can be connected to a power
failure pair and used to provide communications
capability until the AC power to the system is restored.
The power failure pair is located as follows and as
detailed in Figure 3-7 below.

AtJXILIARY EQUIPMENT INTERFACENOTE: When the auxiliary interface feature is being
An industry standard non-electronic telephone device
or a data device can be connected on a line ahead of
the common equipment. The system can detect an
off-hook condition in the connected device and 
turn on
the line 
sta!us light at the telephones to indicate that
the line is busy. 
Table 3-l (given in Section 1) and
Figure 3-8 below detail the auxiliary interfacel
connections.employed, the line to line port reassignment as
discussed on pages 3-5 and 
4- 19 works as
described except in regard to line 2 and line 
4.
Line 2 can only be reassigned to line port 4
and line 4 can only be reassigned to line port 2
Connection is across tip and ring of lines 2 and 4.
The auxiliary interface connections are provided at
terminals 1 and 6 of common equipment line jacks 1
and 2.
