17.1.3 Primitive signals and sequences

The fundamental unit of transfer on a Fibre Channel link is the 8b/10b encoded Transmission Character. Only 256 characters
are required to represent a byte of data so the set of valid transmission characters is sub-divided into Data Characters and Spe-
cial Characters.

A Word is a group of four consecutive transmission characters.

An Ordered Set is a word that starts with a special character (to give word and byte sync) and which has special significance to
the communication protocol. Fibre Channel defines the following types of ordered sets:

•

Frame delimiters

•

Primitive signals

•

Primitive sequences

A Frame Delimiter immediately precedes or follows the contents of a frame (see 17.1.4, “Frames” on page 56). Fibre Channel
defines the following:

•

SOF

Start of frame

•

EOF

End of frame

A Primitive Signal is an ordered set that has special meaning when received by itself. Fibre Channel defines the following:

•

R_RDY

Receiver Ready

•

IDLE

Idle

FC-AL adds the following:

•

ARBx

Arbitrate

•

ARB(F0)

Arbitrate

•

OPNyx

Open Full-duplex

•

OPNyy

Open Half-duplex

•

OPNfr

Open Broadcast Replicate

1

•

OPNyr

Open Selective Replicate

1

•

CLS

Close

•

MRKtx

Mark

1

A Primitive Sequence is an ordered set that is transmitted repeatedly and continuously. Three or more of the ordered sets must
be received consecutively in order to recognize the primitive sequence. Fibre Channel defines the following:

•

NOS

Not Operational

2

•

OLS

Offline

2

•

LR

Link Reset

2

•

LRR

Link Reset Received

2

FC-AL adds the following:

•

LPByx

Loop Port Bypass

•

LPEyx

Loop Port Enable

1. Since normal buffer-to-buffer flow control is disabled when OPNr is used, there is no guarantee that the drive has a buffer available to receive an
in-bound frame. It is therefore, recommended that OPNr not be used.
2. Used to convey information about a dedicated connection and therefore not relevant to FC-AL. If detected during an open connection, the drive
will immediately close. Otherwise it will simply re-transmit.
