Preliminary Information
MH88631
21
XB
External relay contact (K1) connection from XC (Pin 8), activated by loop seize control input
(RC1).
22
VEE
Negative Power Supply
. (-5V).
23
VDD
Positive Power Supply
. (+5V)
24
RXOUT
Audio receive signal (output) tothe RXIN- (Pin 13), via an external decoupling capacitor
(C3).
25
VCC+
Positive analog Power Supply Voltage
. (+12V).
26
GSR
Gain Setting Receive (Input)
. Normally used to set the receive gain with an external
resistor connected to RXOUT (Pin 24).
27
TXIN-
Transmit (Input)
. Differential audio signal from VTR- (Pin 6), via an external capacitor
(C4).
28
VCC-
Negative Analog Power Supply Voltage
. (-12V).
29
TXIN+
Transmit (Input)
. Differential audio signal from VTR- (Pin 6), via an external decoupling
capacitor (C1).
30
AGND
Analog Ground.
31
VR
Audio Receive (Input)
. The four-wire audio signal input to the interface.
32
VX
Audio Transmit (Output)
. The four-wire audio signal output from the interface.
33
RGND
Relay Ground.
34
GSX
Gain Setting Transmit (Input)
. Normally used to set the transmit gain with an external
resistor connected to VX (Pin 32).
35
RC1
Relay Control 1 (Input).
A logic high will activate the relay (K1) to provide loop seize
across Tip and Ring.
36
NETBAL
Network Balance (Input)
. When there is no connection (open), the network is balanced at
600
. When the pin is grounded, the network is balanced at AT&T compromise.
37
RD1
Relay Driver 1 (Output).
Open collector sinks current when RC1 is high. Diode clamp
protected.
38
CD
Clamping Diode.
Normally connects to the positive supply voltage.
39
RD2
Relay Driver 2 (Output).
Open collector sinks current when RC2 is high. Diode clamp
protected.
40
RC2
Relay Driver 2 (Input).
A logic high will activate the relay (K2) to provide proper biasing to
the Tip and Ring. This input control is used for Ground Start Trunk only.
