- -- Changes for RFC1232 (DS1 MIB):
- -- Changes from RFC-1239 applied which include:
- -- removing import of experimental,
- -- adding import of transmission, changing
- -- ds1 to be { transmission 10 }
- -- instead of { experimental 2 }
- -- Changed defintions and references from "DS1" to "Ds1" for
- -- the following: DS1ConfigEntry, DS1IntervalEntry,
- -- DS1CurrentEntry, DS1TotalEntry, DS1FracEntry

- ds1ZBTSI(5)
- }
- ACCESS read-only
- STATUS mandatory
- DESCRIPTION
- "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]). "

- DESCRIPTION
