Description
The Intronic Semiconductor INT2095 is a fully
featured replacement for the industry standard
Up interface layer-1 device. It supports loop
lengths up to 2.0km over AWG24 cable and
provides all signal conditioning, equalization and
adaptive threshold adjustment to optimize line
performance. The backplane interface supports
both IOM1 and IOM2 modes and provides
access to all subchannels of the interface
including B, D, CI and M-channels. Special
function pins (X0-X4) and a master clock output
are included in the device for integration with
other INT2095’s or layer-2 devices.

Description of Terms
ENCKB: Enable clocks in TE mode, deactivated state. Active-low
input signal. When high, the clock outputs are in the high impedance
state.
PFOFF: NT mode Powerfeed off state. Also indicated by a HI on the
C/I channel.
MPF: Main Power Feed serial input, 8-bits synchronous with the B1
channel of the IOM interface.
CONF4: General purpose output which is programmed via the
Monitor channel registers.
TS2-TS0: IOM Timeslot assignment number (0 to 7) in NT mode.
