Standard Details
Supplemental Information for a high-speed serial bus that integrates well with most IEEE standard 32-bit and 64-bit parallel buses is specified. It is intended to extend the usefulness of a low-cost interconnect between external peripherals. This standard follows the IEEE Std 1212-2001 command and status register (CSR) architecture.

This standard describes a high-speed, low-cost serial bus suitable for use as a peripheral bus, a backup to parallel backplane buses, or a local area network. Highlights of the serial bus include the following:
a)Bus transactions that include both block and single quadlet reads and writes, as well as an "isochronous" mode that provides a low-overhead guaranteed bandwidth service.
b)A fair bus access mechanism that guarantees all nodes equal access. The backplane environment adds a priority mechanism, but one that ensures that nodes using the fair protocol are still guaranteed at least partial access.
c)Automatic assignment of node addresses--no need for address switches.
d)A physical layer (PHY) supporting both long-haul and short-haul cable media and backplane buses.
e)Variable speed data transmission based on ISDN-compatible1 bit rates from 24.576 Mbit/s for transistor-transistor logic (TTL) backplanes to 49.152 Mbit/s for backplane transceiver logic (BTL) backplanes. For the cable medium, data transmission rates of 98.304 Mbit/s (known as S100), S200, S400, S800, S1600, and S3200 are supported.
f)A short-haul cable medium that allows up to 16 physical connections (cable hops), each up to 4.5 m, giving a total cable distance of 72 m between any two devices. Bus management recognizes smaller configurations to optimize performance.
g)A long-haul cable medium that permits connections up to 100 m in length over unshielded twisted pair (UTP) cable and glass optical fiber (GOF) and up to 50 m over plastic optical fiber (POF).
h)Consistency with ISO/IEC 13213:1994 (IEEE Std 1212(TM), 1994 Edition).

Existing Standards |
A high-speed serial bus that interates well with most IEEE standard 32-bit and 64-bit parallel buses, as well as such nonbus interconnects as the IEEE Std 1596-1992, Scalable Coherent Interface, is specified. It is intended to provide a low-cost interconnect between cards on the same backplane, cards on otherre backplanes, and external peripherals. This standard follows the IEEE Std 1212-1991 Command and Status Register (CSR) architecture.
|
This standard defines a peer-to-peer data transport (PPDT) protocol between Serial Bus devices that implement Serial Bus Protocol 2 (SBP-2). The facilities specified include device and service discovery, self-configurable (plug and play) binding, and connection management.

Amended information for a high-speed Serial Bus that integrates well with most IEEE stan-dard 32-bit and 64-bit parallel buses is specified. This amendment is intended to extend the usefulness of a low-cost interconnect between external peripherals, as described in IEEE Std 1394-1995. This amendment to IEEE Std 1394-1995 follows the ISO/IEC 13213:1994 Command and Status Register (CSR) Architecture.

|
The model, definition, and behaviors of High Performance Serial Bus bridges, which are devices that can be used to interconnect two separately enumerable buses, are specified.
|
|
This standard provides specifications for a high-speed serial bus that supports both asynchronous and isochronous communication and integrates well with most IEEE standard 32-bit and 64-bit parallel buses. It is intended to provide a low-cost interconnect between cards on the same backplane, cards on otherre backplanes, and external peripherals. Interfaces to longer distance transmission media [such as unshielded twisted pair (UTP), optical fiber, and plastic optical fiber (POF)] allow the interconnection to be extended throughout a local network. This standard follows the command and status register (CSR) architecture of IEEE Std 1212-2001.
