RFL VF-5XP
Dual-Channel Four-Wire E&M Voice Module For
RFL 9508 Analog or Digital SSB Powerline Carrier System
NOTE
When the RFL VF-5XP Module is used in the 9508
Digital Unit (9508D UCC), it will only function as a Service Channel.
DESCRIPTION
The RFL VF-5XP is a dual-channel four-wire E&M voice-frequency module, designed for use in the
RFL 9508. It accepts two voice channels (one speech channel and one speech plus channel) as inputs
and digitizes them. Channel one uses one 64-Kbps time slot, and Channel two uses two 64-Kbps time
slots.
The RFL VF-5XP provides high-quality voice characteristics. It allows E&M signaling of Type I, II,
III and V, with front-panel busy indicators. It has extended-range input and output signal level settings
to facilitate interfaces in most four-wire applications.
All VF-5XP parameters must be programmed using NMS, with the exception of E&M Signaling
which is set up using jumpers, and the Module Address which is set up using switches. The following
is a list of VF-5XP parameters:
o
One-channel or two-channel operation.
o
Selectable Type I, II, III or V signaling.
o
Individual channel enable/disable.
o
Signaling on or off selection.
o Busy
settings.
o
Extended range input/output level settings
o
