MA-301D The MA-301D provides pluggable terminal block connections for a single
VF-5A module. Tip and Ring test points are available for the inputs and
outputs of channels 1 and 2. Audio and signaling connections are available
at the terminal block. No additional SWC or fast transient protection is
provided on this I/O. Refer to Figure 5 for panel view and terminal
connections.

Figure 5. MA-301D Module Adapter
MA-322 The MA-322 accepts a 50-pin Telco connector (Amphenol 57-30500
or equivalent, as shown in Figure 6.) One MA-322 Module Adapter
is used for each RFL VF-5A module, and occupies two rear slots in
the IMUX 2000 chassis. The MA-322 is used to convert both of the
4-wire outputs (Channel 1 and 2) from 4-wire to 2-wire. The
impedance is 600 Ohms, the frequency response is ±2dB from 200Hz
to 3000Hz,
and the transformer loss (hybrid loss) is ≅ 4.0dB.
MA-324
The MA-324 accepts a 50-pin Telco connector (Amphenol 57-30500
or equivalent, as shown in Figure 6.) One MA-324 Module Adapter
is used for each RFL VF-5A module and occupies two rear slots in
the IMUX 2000 chassis. The MA-324 is used to convert one of the
4-wire outputs (Channel 1) from 4-wire to 2-wire. The other 4-wire
output (Channel 2) remains 4-wire. The impedance is 600 Ohms,
the frequency response is ±2dB from
200Hz
to 3000Hz, and the
transformer loss (hybrid loss) is ≅ 4.0dB.
