INSTALLATION
Before the RFL VF-6I can be placed in service, it must be installed in a multiplexer shelf. Installation
involves determining the module slot in the Main Shelf or Repeater Shelf where the module will be
installed, inserting a Module Adapter into the rear of the shelf behind the module slot, connecting all
signal and power wiring to the Module Adapter, checking the settings of all jumpers, and inserting the
module into the front of the shelf.
NOTE
Power supply and time slot considerations may affect the installation of this module into an
existing multiplexer shelf. Refer to the multiplexer manual for more information.
The following instructions are provided for installing RFL VF-6I modules into existing systems. If the
module was included as part of a system, installation was done at the factory. Otherwise, proceed as
follows:
1. Carefully inspect the module for any visible signs of shipping damage. If you suspect damage
to the module, immediately call RFL Customer Service at the number listed at the bottom of
this page.
2. Determine the module slot in the Main Shelf or Repeater Shelf where the RFL VF-6I will be
installed.
RFL VF-6I modules occupy one module slot in the Main Shelf or Repeater
Shelf.
3. Determine which Module Adapter will be used to make connections to the RFL VF-6I
module.
Each module in the IMUX 2000 multiplexer requires a Module Adapter. The
module adapter provides the appropriate connector for the desired interface.
There are four Module Adapters compatible with the RFL VF-6I:
MA-301 The MA-301 accepts a 50-pin Telco connector (Amphenol 57-30500
or equivalent, as shown in Figure 1.) One MA-301 Module Adapter
can be used to connect up to three RFL VF-6I modules, for a total
of up to three voice channels. If you will be using more than one
module with an MA-301, they must be inserted into adjacent slots in
the multiplexer. Ribbon cables are provided with the MA-301 to
make connections to it from the second and third module locations.
