Description
The XE0020 and XE0020C are complete compact
telephone interface modules. As with all Xecom
DAAs the XE0020 and XE0020C include Ring
Detection, Switch-Hook, and Loop Current
Holding Circuits. In addition both the XE0020 and
XE0020C include two line monitors to insure
unobtrusive customer premises operation. The
XE0020C also passes the Caller ID signal through
to the system host.
Xecom designed the XE0020 and XE0020C for
unobtrusive operation in residential applications.
Two integral line monitors prevent interference
with the residents calls.
Connect Detect verifies line availability before the
equipment seizes the line. This will prevent the
equipment from interrupting a residents call.
Handset Interrupt signals the system host to
drop the call in progress when the resident picks-
up an extension phone. This feature permits the
resident to interrupt the call in case of emergency.
Caller ID permits the host to
identify incoming calls and
answer
designated call centers.
Together these features give
residents priority use of the
telephone line without shutting
out the equipment.
