Installation, Section 300 Peripheral Equi.pment issue 2 August 30,1993 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. Table 54. Maximum distances for direct connection to OPX shtions . . . 0, Wiring gauge Max. disfance (in feet) between the OPX Adaptor and the OPX station AWG 22 27877 AWG 24 17532 AWG26 1 11025 One OPX Adaptor (VB-43702) is required for each OPX station. The ringing output of the OPX Adaptor is 225 Vp-p (peak-to-peak) at 20 Hz. When OPX stations are connected through the central office, an external ringer supply may be required. If required, the ringing supply is connected to the OPX Adaptor. The following tools are required to install the OPX Adaptor: - Phillips screwdriver - Needle-nose pliers - Diagona! cutters f 5-l 0
i , Installation, Section 300 Issue 2 Peripheral Equipment August 30,1993 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 either side with diagonal cutters. Then bend the plate back and forth with needle-nose pliers to remove it. Figure 5-S. Cable punch-out pl bte. OPX Aaktor 3. Mount the OPX Adaptor to the wall.

Installation, Section 300 Peripheral Equipment Issue 2 August 30,1993 4. Connect the “R” and “T” leads to a digital extension port on the DBS. . 5. Connect the “GNU’ lead on the OPX Adaptor to the DBS Frame Ground screw. 6. Connect the “TR” and “?T’ leads to the OPX station. 7. Install the cover on the OPX Adaptor. 8. Power the system down then back up, or unplug the cable connected to the digital extension, then plug it back in; Installing an OPX Station Through a Central Office 1. Perform Steps 1 through 5, which begin on page 5- 11. 2. Connect the “TR” and “TT’ leads to the central office. Note: if the central office requests a ground on the tip side of the OPX, strap Pins 1 to 2 on CN3. 3. Connect the OPX station to the central office. 4. If the ringing level at the OPX station is not sufficient, connect a tinging supply to the “E-RG+” and “E-RG-” terminals on the OPX Adaptor. Note: Signals to the external ringer should not exceed 300 Vp-p. 5. If a ringing supply is used, cut Straps Jl and J2 on the OPX Adaptor. 6. Install the cover on the OPX Adaptor. 7. Power the system down then back up, or unplug the cable connected to the digital extension, then plug it back in.

Installation, Section 300 Issue 2 Peripheral Equipment August 30; 1993 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 600 Ohms; the loss/gain setting is OdB. Installation 1. Connect the paging amplifier to CN4 on the DBS Connector Panel. (See Figure 5-7 on page 5- 15.) 2. Connect the paging speakers to the amplifier. 3. Connect the relays to the amplifier. 4. Connect the relays to the +24V and zone paging terminals (20-24) on the Connector Panel. 5-l 4

Installation, Section 300 issue 2 Peripheral Equipment August 30, 1993 External Rinser WNA Device) Guidelines . . . l Installation 1 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). Connect the external ringer to the “C” and “M” terminals on the Connector Panel. (See Figure 5-8 on page 5-17.) Note: Connecting the ringer to the “c” and “M” terminals provides a “ 1 second on/3 seconds off’ ringing pattern. Connecting to “C” and “B” terminals provides a “1 second off/3 seconds on” ringing pattern. 2. Connect the external ringer to its DC power source.

Installation, Section 300 Issue 2 Peripheral Equipment August 30,1993 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 following tools are required to install the PFU: - Phillips screwdriver - Needle-nose pliers - Diagonal cutters installation 1. Remove the cover from the Power Failure Unit (PFU). 2. Remove the cable punch-out plate (Figure 5-9) to make a opening for the cables coming into the PF’U. To remove the plate, cut the grooves on either side with diagonal cutters. Then bend the plate back and forth with needle-nose pliers to remove it. 5-18
