Description
Ring is one of two signals which form the telephone network connection (RJ11 Pin 4). The
XE0020 is not sensitive to the polarity of the battery voltage on the telephone line. Ring has
1500 volts isolation from the rest of the circuitry which must be preserved throughout the
system.
Tip provides the second connection to the telephone network (RJ11 Pin 3). Tip has 1500
volts isolation from the rest of the circuitry. This isolation must be preserved throughout the
system.
Hook-switch relay control an active high input. A high on OH closes the internal relay and
connects the equipment to the telephone line.
T1 connects directly to the secondary side of the XE0020's internal telephone line
transformer.
This signal is used as common reference for all of the control signals in the XE0020. Signals
on T1 and T2 are not referenced to ground.
