Description
The Mitel MT91600 provides an interface between a
switching system and a subscriber loop, mainly for
short loop SLIC applications. The functions provided
by the MT91600 include battery feed, programmable
constant current, 2W to 4W conversion, off-hook and
dial pulse detection, user definable line and network
balance
impedance’s
and
programming the audio gain externally. The device is
fabricated as a CMOS circuit in a 28 pin SSOP
package.
