Description
Xecom's XE10X0 Single In-Line telephone
interfaces offer complete, highly compact telephone
interfaces for Europe, Japan and North America.
The XE10X0 family includes six models. Each
meets the regulatory requirements for connection
to the telephone network in one or more countries.
A common single in-line package provides
maximum flexibility in component placement and
permits world-wide connectivity from one, simple
circuit board layout.
XE1030 complies with the requirements of several
European countries including the United Kingdom.
It supplies 3750 volts isolation from the telephone
line and has BABT, UL and CSA approval.
XE1040 provides the circuitry to connect to the
German telephone network. It includes the 16
Khz Meter Tone Filter and 3750 volts isolation.
The XE1040 also has BABT approval.
XE1050 meets French telephone network
requirements. It includes BABT approval, over
current protection on both tip and ring, and
provides 3750 volt isolation.
XE1060 meets telecom requirements for North
America and Japan. It provides 1500 volts
isolation from the telephone network and is FCC
part 68 compliant.
XE1070 provides a connection to the Italian
telephone network. XE1070 includes BABT
approval and provides 3750 volt isolation.
XE1080 connects to the Spanish telephone
network. XE1080 includes BABT approval and
provides 3750 volt isolation.

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.
