DESCRIPTION
The E123MUX is a CMOS VLSI device that provides the
E13 functions needed to multiplex and demultiplex 16 inde-
pendent E1 signals to and from an E3 signal that conforms
to the ITU-T G.751 Recommendation. The E1 and E3 sig-
nal interfaces can be either dual unipolar (rail) or NRZ. Dig-
ital phase-locked loop circuits are provided for the received
E1 signals, but they may be bypassed.
The E123MUX can also be configured to operate as an E12
or E23 multiplexer and demultiplexer. Sixteen E1 signals
can be multiplexed and demultiplexed to and from four E2
signals that conform to the ITU-T G.742 Recommendation.
Alternatively, four E2 signals can multiplexed and demulti-
plexed to and from one E3 signal. The E2 signal interfaces
are NRZ only. The E123MUX uses memory locations for
setting control bits and reporting status information. The
status bits have maskable interrupt control bits.
