Connectionless frames

referred to individually or collectively).
Connectionless service
Communication between two N_Ports performed without a dedicated connection.
Continuously increasing relative offset
The relationship specified between relative offset values contained in frame (n) and frame (n+1) of an informa-
tion category within a single Sequence.
COR
Camp-On Request.
Credit

mum number of outstanding frames which can be transmitted by that N_Port or F_Port without causing a buffer
overrun condition at the receiver.
Credit_CNT
Credit Count.
CTI
Circuit Initiator.
CTR
Circuit Recipient.
Current running disparity
The running disparity present at a transmitter when Encoding of a valid data byte or special code is initiated, or
at a receiver when decoding of a transmission character is initiated.
D_ID
Destination_Identifier.
Data character
Any transmission character associated by the transmission code with a valid data byte.
Data frame
A frame containing information meant for FC-4/ULP or the link application.
Data out delivery service
A confirmed service used by the device server to request the transfer of data from the application client.
dB
Decibel.
dBm
