GENERAL DESCRIPTION
The DS21Q50 E1 quad transceiver contains all the
necessary functions for connecting to four E1 lines.
The on-board clock/data recovery circuitry coverts
the AMI/HDB3 E1 waveforms to an NRZ serial
stream. The DS21Q50 automatically adjusts to E1
22AWG (0.6mm) twisted-pair cables from 0km to
over 2km in length. The device can generate the
necessary G.703 waveshapes for both 75
W coax and
120
W twisted-pair cables. The on-board jitter
attenuators (selectable to either 32 bits or 128 bits)
can be placed in either the transmit or receive data
paths. The framers locate the frame and multiframe
boundaries and monitor the data streams for alarms.
The device contains a set of internal registers, from
which the user can access and control the operation
of the unit by the parallel control port or serial port.
The device fully meets all the latest E1 specifications
including ITU-T G.703, G.704, G.706, G.823, G.732,
and I.431 ETS 300 011, ETS 300 233, and ETS 300
166 as well as CTR12 and CTR4.
