VTX
Transmit Output, 4-Wire Side - A low impedance analog output which represents the differential voltage
across TIP and RING. Transhybrid balancing must be performed beyond this output to completely imple-
ment two to four wire conversion. This output is referenced to analog ground. Since the DC level of this
output varies with loop current, capacitive coupling to the next stage is necessary.
20
PRI
A TTL compatible input used to control PR. PRI active High = PR active low.
21
PR
An active low open collector output. Can be used to drive a Polarity Reversal Relay.
22
BG
Battery Ground - Tube connected to zero potential. All loop current and some quiescent current flows into
this terminal.
23
RD
Ring Relay Driver - An active low open collector output. Used to drive a relay that switches ringing signals
onto the 2-Wire line.
24
VFB
Feedback input to the tip feed amplifier; may be used in conjunction with transmit output signal and the
spare op amp to accommodate 2-Wire line impedance matching.
25
TF
Tip Feed - A low impedance analog output connected to the TIP terminal through a feed resistor. Functions
with the RF terminal to provide loop current, and to feed voice signals to the telephone set and to sink lon-
gitudinal currents.
26
RF
Ring Feed - A low impedance analog output connected to the RING terminal through a feed resistor. Func-
tions with the TF terminal to provide loop current, feed voice signals to the telephone set, and to sink lon-
gitudinal currents.
27
VB-
The battery voltage source. The most negative supply.
28
C2
Capacitor #2 - An external capacitor to be connected between this terminal and ground. It prevents false
ring trip detection from occurring when longitudinal currents are induced onto the subscriber loop from pow-
er lines and other noise sources. This capacitor should be nonpolarized.
