`viewpoints and interests to achieve the final product. Volunteers are not necessarily members of the Institute and serve with-
`out compensation. While the IEEE administers the process and establishes rules to promote fairness in the consensus devel-
`opment process, the IEEE does not independently evaluate, test, or verify the accuracy of any of the information contained

`Introduction
`
`(This introduction is not part of IEEE Std 1394b-2002, IEEE Standard for a High-Performance Serial Bus—Amendment
`2.)
`
`Work on IEEE Std 1394b-2002 was begun in the winter of 1997 at a meeting of the 1394TA in Eind-
`hoven. By that time, it had become evident that
` was going to be widely deployed and
`IEEE Std 1394-1995
`that many devices, especially new, digital consumer products, were going to have IEEE 1394 as the pri-
`mary external interface. In the first meetings of this group, considerable sentiment existed for broaden-
`ing the number and types of devices that would be able to use the IEEE 1394 interface and thereby
`making the interface more valuable to the end user. While attempting to broaden the scope of the
`IEEE 1394 interface, two barriers were discovered that made wider deployment difficult: the interface
`was constrained to operate over a fairly short distance and it could not handle higher data rates.
`
`After some preliminary investigations, the group concluded that these problems were best solved by a
`change in coding. While the data-strobe (DS) coding used in IEEE Std 1394-1995 was a simple, self-
`clocking scheme, the fact that it is not dc balanced made it impractical to use over longer distances. Fur-
`thermore, accumulated skew on a long-distance connection makes it hard to maintain the timing rela-
`tionships between the data and the strobe lines, especially at higher data rates. The group rapidly
`converged on the notion of using a variant of 8B/10B coding developed by IBM for the longer distances
`and higher speeds defined in IEEE Std 1394b-2002. Where the connection between devices was copper
`cable of 5 m or less, some or all of the ports on a new physical layer (PHY) developed to support this
`standard could be able to signal using either DS or the new signaling scheme (dubbed
`). These
`Beta mode
` ports would be able to select the optimum signaling method for the connection and thereby be
`bilingual
`able to fully interoperate with existing devices that are compliant with IEEE Std 1394-1995 and IEEE
`Std 1394a
`-2000.
`™
`
`The new signalling system provided a route to solving a second major problem, i.e., the lack of scalabil-
`ity of the IEEE 1394 arbitration scheme as signaling rates are increased. The use of 8B/10B encoding
`allows the transmission of data to be overlapped with the transmission of arbitration signals in the
`reverse direction. The use of overlapped arbitration is extended by one level of pipelining, with the result
`that in a purely IEEE 1394b bus the need for arbitration gaps is entirely eliminated. In fact, on a bus
`with all connections operating in Beta mode, the setting of gap count has no utility as the bus is com-
`pletely self-timed.
`
`As work progressed, the group became interested in applying the new coding scheme to a large variety
`of interconnect media including plastic optical fiber (POF), glass optical fiber (GOF), and Category 5
`(CAT-5) unshielded twisted pair (UTP). This goal greatly expanded the scope of the work and made it
`necessary to divide the IEEE P1394b Working Group into various task groups. The leaders of these
`groups were largely responsible for the development of IEEE Std 1394b-2002. Because of the length of
`the project, some of the task groups had more than one leader. The task groups, their leaders, and their
`contributions are as follows:
`
`—
`
`—
`
`. Colin Whitby-Strevens. This group adopted the work from the Fibre Channel specifi-
`Glass Fiber
`cation for use in IEEE Std 1394b-2002. The jitter work done in this group was adapted for use in
`all the media.
`
`. Taka Fujimori, Shuntaro Yamazaki, Victoria K. M. Teng, and Kazuki Nakamura.
`Plastic Fiber
`This group actually developed a standard around a single connector that allowed interoperation
`and intermating of both plastic fiber or large-diameter hard polymer clad fiber (HPCF). This con-
`nector can be used at a speed of S100.
`
`—
`
`. Colin Whitby-Strevens and Alistair Coles. This group built on work done in the 100BaseT
`UTP5
`standard with extensive changes to simplify the coding and transmission over CAT-5 UTP.

`. Eric Hannah. This group provided the electrical characteristics for the base-
`Standard Electrical
`line PHY. This required a great deal of simulation work by Eric Hannah in support of the Cable &
`Connector task group.
`
`. Colin Whitby-Strevens. This group created the mechanisms that allow a B PHY
`Start-up Protocol
`to determine whether it is attached to another B PHY and to select the signaling frequency before
`the connection is completed. Peng Zhang and Jim Nave proposed the speed signaling scheme us-
`ing a toning mechanism. This was enhanced by Colin Whitby-Strevens to deal with all the con-
`nectivity aspects of B ports. The loop-breaking protocol was developed by Jerry Hauck and David
`Wooten.
`
`. Max Bassler. This group originally tried to characterize the 4- and 6-circuit
`Cable & Connector
`connectors used in IEEE Std 1394-1995 and IEEE Std 1394a-2000 for use at the higher speeds
`defined in IEEE Std 1394b-2002. This work was abandoned after two years, and a new, small
`form-factor connector was developed by Dave Brunker for use on devices capable of Beta-mode
`signaling.
`
`. David LaFollette, Alistair Coles, and Mike Teener. This group developed
`Protocol Accelerations
`the bus owner/supervisor/selector (BOSS) arbitration scheme that is the basis for all of the arbitra-
`tion and control. The original concepts were proposed by David LaFollette and Jerry Hauck. Their
`work was supplemented by contributions from Alistair Coles, Mike Teener, Jim Skidmore, and
`David Wooten.
`
`. Alistair Coles. This group developed the coding and scrambling methods used for
`Port Logic
`Beta ports. Alistair Coles and Eric Deliot developed the single character control codes and arbitra-
`tion tokens. This group also selected the scrambling method for the symbols. The method of deal-
`ing with deletable symbols was adapted from the Fibre Channel specification by Jerry Hauck and
`Mike Teener.
`
`—
`
`. Jerry Hauck. This group did computer simulations of the various pieces of the B PHY,
`Simulation
`but most of the simulation was mental and took place in Jerry Hauck’s mind. This turned out to
`be a much more efficient method of finding problems than a computer simulation.
`
`—
`
`. Richard Churchill and Steve Bard. This group developed the standby-restore protocol.
`Low-power
`
`—
`
`. Martin Sodos, Sean Killeen, and David Wooten. This group developed the
`PHY-link/PIL-FOP
`source synchronous version of the PHY-link interface and the PIL-FOP interface. The point-to-
`point (P2P) packet protocol for sending in-band status and register information between the PHY
`that is integrated into the link (PIL) and the fan-out PHY (FOP) was developed by Jerry Hauck
`and David Wooten.
`
`—
`
`. Colin Whitby-Strevens. Although not done as a formal task group, the work that Colin
`C code
`Whitby-Strevens did in developing and maintaining the C code for the standard bears special rec-
`ognition.
`
`The IEEE P1394b Working Group first met under the chairmanship of Mike Teener in January 1997.
`David Wooten became chair within a few months, and the working group continued to meet approxi-
`mately every month until the editorial work was completed in October of 1999 at which time the work-
`ing group voted to go to ballot. The proposed standard was balloted in March and April of 2000 with
`over 80% of the votes in favor. A Ballot Response Committee (BRC) was formed to review the com-
`ments. Those comments pointed out many significant omissions and errors in the draft that the BRC cor-
`rected over the next seven months of meetings. The BRC completed its work on this standard in
`February of 2001.
`
`The ballot for the February 2001 version of the standard passed but with comments that pointed out
`some flaws that would need to be corrected before the standard could be released. The BRC met several
`times from June to September and completed work on a new version of the standard in September of
`2001.
