read-write “This variable describes
the variety of Zero Code
Suppression used on the
link, which in turn
affects a number of its
characteristics. dsx1JBZS
refers the Jammed Bit
Zero Suppression, in
which the AT&T
specification of at least
one pulse every 8 bit
periods is literally
implemented by forcing
a pulse in bit 8 of each
channel. Thus, only
seven bits per channel, or
1.344 Mbps, is available
for data. dsx1B8ZS
refers to the use of a
specified pattern of
normal bits and bipolar
violations which are used
to replace a sequence of
eight zero bits.
ANSI Clear Channels
may use dsx1ZBTSI, or
Zero Byte Time Slot
Interchange.
E1 links, with or without
CRC, use dsx1HDB3 or
dsx1AMI.
dsx1AMI refers to a
mode wherein no zero
code suppression is
present and the line
encoding does not solve
the problem directly. In
this application, the
higher layer must
provide data which
meets or exceeds the
pulse density
requirements, such as
inverting HDLC data.”
dsx1B8ZS(2) - the
