Pin Descriptions
PIN
NAME
DESCRIPTION
1
Ring
Ring provides one half of the two-wire connection to the telephone line. Ring
is isolated from all other circuitry. The XE1060 provides a 1500 Volt
isolation barrier; the remaining XE10X0 models provide a 3750 volt isolation
barrier. This isolation must be preserved throughout the system. This
isolation can be maintained by selecting properly rated components and
maintaining sufficient creepage and clearance distances.
2
Tip
Tip provides one half of the two-wire connection to the telephone line. Tip is
isolated from all other circuitry. The XE1060 provides a 1500 Volt isolation
barrier; the remaining XE10X0 models provide a 3750 volt isolation barrier.
This isolation must be preserved throughout the system. This isolation can
be maintained by selecting properly rated components and maintaining
sufficient creepage and clearance distances.
3
/OH
/OH is an active low input to the XE10X0 DAA module. It controls the internal
hookswitch. A low on OH closes the hookswitch and connects the
equipment to the telephone line.
4
/MUTE
This active low input provides low impedance pulse dialing in the XE1040,
XE1050, and XE1070. Presenting a low impedance to the telephone line
during pulse dialing is required in many European countries including
Germany, France and Italy.
5
T1
T1 provides half of the differential input/output connection to the secondary
side of the internal telephone line transformer.
6
T2
T2 provides half of the differential input/output connection to the secondary
side of the internal telephone line transformer.
7
GND
This pin provides ground reference for the RI, /OH and /Mute control lines.
There is no connection between ground and the telephone line (primary) side
of the XE10X0 DAA.
8
RI
Ring Indicate is an active high output from the DAA module. When a valid
ring signal appears on Tip and Ring, the DAA provides a pulse train at ring
frequency on RI.
9
VCC
This pin provides 5 volt DC power for the RI, /OH and /Mute control lines.
There is no connection between VCC and the telephone line (primary) side of
the XE10X0 DAA.
