www.DataSheet4U.com XE0020 and XE0020C 8/97 Telephone Line Interface with Active Line Monitoring 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 picksup 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 only those from designated call centers. T1 Features * Small Size: 2.0" by 0.5" by 0.4" thick; * Supports data transfer at 33,600 bps; * FCC Part 68 Compliant; * Ring Detection; * Continuous Connect Detect Monitor; * Handset Interrupt Monitor * Single +5 Volt Power Supply; * Hookswitch Control * Caller ID Signal Path (XE0020C) Models XE0020: includes ring detect , hookswitch, Handset Interrupt, Connect Detect, telephone line transformer, loop current holding circuit; XE0020C: XE0020 features plus Caller ID signal pass through; Block Diagram Caller ID (optional) TIP Line Transformer Loop Current Holding Circuit Together these features give residents priority use of the telephone line without shutting out the equipment.

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 intern.
