ds1JammedBit(1),ds1B8ZS(2),ds1InvertedHDLC(3),ds1HDB3(4),ds1ZBTSI(5)}ACCESSread-onlySTATUSmandatoryDESCRIPTION"This variable describes the variety of Zero Code
Suppression used on the link, which in turn
affects a number of its characteristics.
ds1JammedBit refers the Jammed bit Zero Encoding,
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.
ds1B8ZS 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 (see
[14]). In this context, all eight bits in a
channel are technically available for data, but
care must be taken with D4 encoded data to avoid
having HDLC Flag streams imitate spurious Yellow
Alarm conditions. Typically, one bit per frame is
ignored to force flag streams to rotate, thereby
avoiding this error type. CCITT Recommendation
G.703 [11] may be referred to for further
definition of these.
ds1InvertedHDLC refers to the practice, common on
HDLC encoded DS1 data links, of inverting the data
between the serial interface chip and the CSU.
Since HDLC guarantees one zero every 6 bits in the
worst case, while the standards call for (in
effect) at least one pulse every eight, inverted
HDLC enjoys 4/24 one's density on the line, which
may improve the effective clock stability of a DS1
line. As with B8ZS, all eight bits in a channel
are technically available for data, but care must
be taken with D4 encoded data to avoid having HDLC
Flag streams imitate spurious Yellow Alarm
conditions. Typically, one bit per frame is
ignored to force flag streams to rotate, thereby
avoiding this error type.
ANSI Clear Channels may use ds1ZBTSI, or Zero Byte
Time Slot Interchange (see [14]).
G.704 links, with or without CRC, use ds1HDB3 (see
[11]). "::={ ds1ConfigEntry 6}ds1Loopback OBJECT-TYPESYNTAXINTEGER{ds1NoLoop(1),ds1LocalLoopbackLocalSide(2),ds1LocalLoopbackRemoteSide(3),ds1RemoteLoopbackLocalSide(4),ds1RemoteLoopbackRemoteSide(5)
