Ring provides one half of the two-wire connection to the telephone line. Ring
is isolated from all other circuitry.
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.
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.
/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.
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.
T1 provides half of the differential input/output connection to the secondary
side of the internal telephone line transformer.
T2 provides half of the differential input/output connection to the secondary
side of the internal telephone line transformer.
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.
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.
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.
