VCC
VCC provides the + 5 volt power source for the XE0020.
7
T2
T2 connects directly to the secondary side of the XE0020"s internal telephone line
transformer.
8
/RI
Ring Indicate, output, active low, TTL, RI provides a ring frequency pulse train representation.
An external 56K pull-up resistor is required to correctly bias the ring indicate output.
9
HInt
Handset Interrupt is an active high output from the modem. HInt goes high for one second if
an extension telephone is picked-up while the DAA has control of the line. When the host
sees HInt go high, it should immediately lower OH to disconnect the XE0020 or XE0020C
from the telephone line.
10
/CD
Connect Detect, output, active low, TTL. /CD indicates that the XE0020 is connected to the
telephone line and the telephone line is not in use.
