DESCRIPTION
1
VCC
---
+5 Volt power;
13
D/V
I
A TTL Low on Data/Voice selects a transmit level output of 0 dBm for voice or
DTMF signaling applications. A High on Data/Voice sets a maximum -9 dBm
transmit level for data transfer.
14
GND
---
Ground reference for the XE0068;
18
XMIT
I
XMIT is the Analog input signal to the XE0068. The input impedance on XMIT is
typically 10 Kohms at 1800 Hz. Signals placed on XMIT less than 0 dBm will be
placed on the telephone line at a maximum of -9 dBm when the Data/Voice signal
is driven high and a maximum of 0 dBm when Data/Voice is driven low.
19
RCVR
O
RCVR is the Analog output signal from the 2-4 wire converter. The output imped-
ance of RCVR is typically 10 ohms at 1800 hz. The signal level on RCVR will be
within 1 dBm of the received signal level present on the telephone line.
21
OH
I
Hookswitch control. A High on OH closes the internal relay to connect the equipment
to the phone line.
22
RI
O
Ring Indicate, output, active low, TTL, indicates the modem is receiving a ring signal.
24
Ring
---
Ring connection to the phone line (RJ11 Pin 4).
