Off-Premises Adaptor COPX) 
Guidelines 
l Analog phones can be connected as off-premise stations through a direct line 
to the DBS or through the central office, depending on how far the stations 
are from the OPX Adaptor. 
Table 5-4 shows how far the OPX stations can be from the adaptor without 
going through a CO.

Installation 
The following procedures describe direct OPX connection and.OPX connection 
through a CO. Refer to Figure 5-6 
on page 5- 13 when installing the OPX. 
Installing an OPX Station Without Going Through a Central Office 
1. Remove the cover from the OPX Adaptor. 
2. Remove the cable punch-out plate (Figure 5- 11) to make an opening for the 
cables coming into the OPX Adaptor. 
To remove the plate, cut the grooves on...

Paginq 
Guidelines 
l The paging amplifier, relays, and speakers are not provided with the DBS. 
They must be purchased separately. 
l The maximum current for each zone paging terminal on the Connector Panel 
(ZOZ4) is 50 mA; the resistance of the relay used for each zone paging 
terminal must be 2600 to 2800 Ohms. 
l Connector 4 (CN4) on the Connector Panel is used to connect the paging 
amplifier. The output impedance of CN4 is...

An external ringer can be used to alert users when Universal Night Answer 
(UNA) calls come in. 
The external ringer is not provided with the DBS. It must be purchased 
separately. 
UNA calls can also be set to ring over an external paging system. 
The contact rating for the “C” and “M” terminals is 30V DC, 
1 amp 
(maximum).

Power Failure Transfer 
Guidelines 
l Up to four SLTs can be connected to the Power Failure Unit (VA-43703). If a 
power failure occurs, the SLTs will automatically receive dial tone from the 
central office. DBS features and restrictions do not apply when the SLTs are 
receiving dial tone from the CO. 
l If a call is in progress through the Power Failure Unit (PFU) when the power 
is restored, the call will be disconnected. 
l The...
