GENERAL DESCRIPTION
The
DS21354/DS213554
single-chip
transceivers
(SCTs) contain all the necessary functions to connect to
E1 lines. The devices are upward-compatible versions
of the DS2153 and DS2154 SCTs. The on-board
clock/data recovery circuitry coverts the AMI/HDB3 E1
waveforms to an NRZ serial stream. Both devices
automatically adjust to E1 22AWG (0.6mm) twisted-
pair cables from 0 to over 2km in length. They can
generate the necessary G.703 waveshapes for both 75
W
coax and 120
W twisted cables. The on-board jitter
attenuator (selectable to either 32 bits or 128 bits) can
be placed in either the transmit or receive data paths.
The framer locates the frame and multiframe
boundaries and monitors the data stream for alarms. It is
also used for extracting and inserting signaling data, Si,
and Sa-bit information. The on-board HDLC controller
can be used for Sa-bit links or DS0s. The devices
contain a set of internal registers that the user can
access to control the operation of the units. Quick
access through the parallel control port allows a single
controller to handle many E1 lines. The devices fully
meet all the latest E1 specifications, including ITU-T
G.703, G.704, G.706, G.823, G.732, and I.431, ETS
300 011, 300 233, and 300 166, as well as CTR12 and
CTR4.
