7702/3BPX-LB RF L-Band Bypass Protection Switch
Revision 1.3 7702/3BPX-LB - 1
1. OVERVIEW
The 7702BPX-LB / 7703BPX-LB is a wide band 2 x 1 RF protection switch that provides auto-changeover
capability by detecting a change in the input power level. Manual control or automation control via the GPI
port is also provided. This is a latching switch which maintains switch state on loss of power. It is
designed for L-band earth station links and operates over a wide frequency range of 950MHz to 2150MHz.
The 7703BPX-LB has integrated VistaLINK®technology for remote control and monitoring capability via
SNMP. This provides the user with the ability to locally or remotely configure and monitor parameters
such as module status, selected input, power level and switching threshold.
In the auto-changeover application, both products can be configured to have a Main input and a Standby
input. In this configuration, it will automatically switch to the Standby input when the Main input power is
weak or lost. It can also be set to auto-switch back to the Main source when this signal is re-established.
The 7702BPX-LB / 7703BPX-LB occupies one card slot and can be housed in either a 1RU frame, which
will hold up to three modules, or a 3RU frame, which will hold up to 15 modules.
Features:
Intelligent auto switching with input power detection
User-definable threshold levels on 7703BPX-LB version
Maintains switch state and RF channel on loss of power to card or frame
Supports automatic or manual control via GPI or SNMP on 7703BPX-LB
Switch state indication via GPO
Card edge LEDs indicate active input channels, output channel and power levels below threshold
Fully hot-swappable from front of frame
Comprehensive signal and card status monitoring via four digit card edge display or remotely
through SNMP and VistaLINK®on 7703 version
VistaLINK®capability is available when 7703BPX-LB modules are used with the 3RU 7800FR or
350FR portable frame and a 7700FC VistaLINK®Frame Controller module in slot 1 of the frame

Figure 1-3: Typical Application of Protection Switch in L-band Downlink Transport System
This diagram illustrates the use of the BPX-LB as a protection switch in an earth station L-band satellite
downlink transport system. The received Horizontal and Vertical polarizations are fed into LNB (Low
Noise Block converter) and downconverted to L-band frequency (950 – 2150MHz). The Evertz
Microsystems 7707LTA L-band optical transmitter converts the RF input to an optical signal that can be
transported up to 60km from the antenna site to the Network Operations Centre (NOC). The 7707LR L-
band optical receiver converts the optical signal to an RF output which can be directed to an L-band router
for switching and distribution. In this application diagram, the BPX-LB is used to provide protection
against router failure and directs the L-band signal to the appropriate receiver. In case of power failure to
the switch, the latching mechanism keeps the switch in the same state upon failure.

2.1. GPIO
A 6-pin removable terminal block labeled GPIO contains 2 GPI inputs and 2 GPO outputs
GPI’s: The two top pins on the 6 pin terminal strip are used for two General Purpose inputs (GPI). The
GPIs can be configured as active high or low by setting DIP switch 3. GPIs are active low
when DIP switch 3 is Off and GPIs are active high when DIP switch 3 is On (positioned closest
to the PCB). The GPI inputs are opto isolated with an internal pull-up resistor to +5V or +12V
as shown in Figure 2-2. See section 6.4 for information on selecting the pull-up voltage.

6.1. SELECTING WHETHER LOCAL FAULTS WILL BE MONITORED
BY THE GLOBAL FRAME STATUS
The FRAME STATUS jumper J9 located near the top front of the module determines whether local faults
(as shown by the Local Fault indicator) will be connected to the 7700FR frame's global status bus.
FRAME STATUS: To monitor faults on this module with the frame status indicators (on the Power
Supply FRAME STATUS LED's and on the Frame's Fault Tally output) install this jumper in
the On position. (Default)
When this jumper is installed in the Off position local faults on this module will not be
monitored.
6.2. MONITORING AND CONTROL OF 7703BPX-LB CARDS THROUGH SNMP
OR CARD EDGE MENU SYSTEM
The card does not require any reconfiguration or adjustment to monitor and control through SNMP or the
card edge menu system. Updates to configuration and status are visible in both systems.
6.3. CONFIGURING THE MODULE FOR FIRMWARE UPGRADES (7703BPX-LB ONLY)
UPGRADE: The UPGRADE jumper J12 is used when firmware upgrades are being done to the module.
For normal operation it should be installed in the RUN position. See the Upgrading
Firmware chapter in the front of the manual binder for more information.
To upgrade the firmware in the module unit pull it out of the frame. Move the UPGRADE
jumper into the UPGRADE position. Install the Upgrade cable provided (located in the vinyl
pouch in the front of this manual) onto the SERIAL header J14 at the card edge. Re-install
the module into the frame. Run the upgrade as described in the Upgrading Firmware
chapter of this manual. Once the upgrade is completed, remove the module from the
frame, move the UPGRADE jumper into the RUN position, remove the upgrade cable and
re-install the module. The module is now ready for normal operation.
6.4. SELECTING THE GPI PULL-UP VOLTAGE
The GPI jumpers J4 and J5, located at the rear of the module, selects whether the general purpose inputs
GPI1 and GPI2 will be pulled up to +5 volts or +12 Volts. Figure 2-2 shows the jumper configuration and
the GPI input schematic. Jumper J5 is used for GPI1 and J4 is used for GPI2.
GPI: To set the pull-up voltage to +5 volts set the jumper to the LO position
To set the pull-up voltage to +12 volts set the jumper to the HI position
6.5. USING THE GPO OUTPUTS
There are three pins on the 6 pin terminal strip dedicated to the GPO, NC (Normally Closed), NO
(Normally Open) and Common, connected as shown in the circuit diagram of section 2.1. The common
connection will switch between NC and NO on a change in state of the RF switch. This GPO is intended
to indicate a change in state of the switch. The signals on NC and NO are to be provided by the user.

7. VistaLINK®REMOTE MONITORING/CONTROL (7703BPX-LB ONLY)
7.1. What is VistaLINK®?
VistaLINK®is Evertz’ remote monitoring and configuration platform which operates over an Ethernet
network using Simple Network Management Protocol (SNMP). SNMP is a standard computer network
protocol that enables different devices sharing the same network to communicate with each other.
VistaLINK®provides centralized alarm management, which monitors, reports, and logs all incoming alarm
events and dispatches alerts to all the VLPro Clients connected to the server. Card configuration through
VistaLINK®PRO can be performed on an individual or multi-card basis using simple copy and paste
routines, which reduces the time to configure each module separately. Finally, VistaLINK®enables the
user to configure devices in the network from a central station and receive feedback that the configuration
has been carried out.
There are 3 components of SNMP:
1. An SNMP manager also known as a Network Management System (NMS) is a computer running
special software that communicates with the devices in the network. Evertz VistaLINK®Pro Manager
graphical user interface (GUI), third party or custom manager software may be used to monitor and
control Evertz VistaLINK®enabled fiber optic products.
2. Managed devices (such as 7707BPX cards), each with a unique address (OID), communicate with
the NMS through an SNMP Agent. Evertz VistaLINK®enabled 7700 series modules reside in the
3RU 7700FR-C MultiFrame and communicate with the manager via the 7700FC VistaLINK®frame
controller module, which serves as the Agent.
3. A virtual database known as the Management Information Base (MIB) lists all the variables being
monitored, which both the Manager and Agent understand. Please contact Evertz for further
information about obtaining a copy of the MIB for interfacing to a third party Manager/NMS.
For more information on connecting and configuring the VistaLINK®network, see the 7700FC Frame
Controller chapter.
