High-Performance Quad DAA Module
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.
