XECOM XE0046
High-Performance Quad DAA Module
XE0046
02/98
Description
Xecom created the XE0046 for high-performance,
multi-line applications. The XE0046 integrates
four high performance DAA's into a single
compact module. Each DAA circuit operates
independently of all the others.
Like all of Xecom's DAA modules, the XE00046
integrates a Ring Detect Circuit, Loop Current
Holding Circuit, Solid-State Hookswitch, and
Telephone Line Transformer for each line. The
XE0046 also provides each line with a path for
the Caller ID signal from the telephone network
and a two-to-four wire convertor. The two-to-four
wire convertor separates the receive signal from
the transmit signal.
Below is a list of the special features incorporated
into the XE0046 for high-performance, multi-line
applications.
XE0046 Features
* Four Individual DAA's in a Single Package;
* Each DAA supports 33,600 bps data transfer;
* Each DAA provides a path for the Caller ID
signal from t
he phone company central office;
* Each DAA includes a 2/4 four wire convertor;
* Each DAA passes network signaling up to 0
dBm without distortion.
* Small Size: 2.5 inches long, 1.5 inches wide,
and 0.6 inches high;
* FCC Part 68 Compliant;
* Individual Ring Detection for each line;
* Each DAA integrates a Low-Distortion
Telephone Line Transformer;
* Each DAA provides a1500 volts isolation
between the phone line and all other circuits;
* Solid-State Hookswitch Control for each line;
