Glossary Chassis The metal frame in which the switch and switch components are mounted. Circuit An established communication path between two ports. Consists of two virtual circuits capable of transmitting in opposite directions. See also Link. Class 1 Service that provides a dedicated connection between two ports (also called connection-oriented service), with notification of delivery or nondelivery. Class 2 Service that provides multiplex and connection-less frame switching service between two ports, with notification of delivery or nondelivery. Class 3 Service that provides a connection-less frame switching service between two ports, without notification of delivery or nondelivery of data. Can also be used to provide a multicast connection between the originator and recipients, with notification of delivery or nondelivery. Class 4 Connection-oriented service that provides a virtual circuit between two ports, with notification of delivery or nondelivery. Allows fractional parts of the bandwidth to be used in a virtual circuit. Class 6 Connection-oriented service that provides a multicast connection between the multicast originator and recipients, with notification of delivery or nondelivery. Class F Connection-less service for control traffic between switches, with notification of delivery or nondelivery of data between the E_Ports. Class of Service A specified set of delivery characteristics and attributes for frame delivery. CLS Close Primitive Signal. The protocol used by a port in an arbitrated loop to close a circuit. Code Balance The ratio of one bit to the total number of transmitted bits. Comma A unique pattern (either 1100000 or 0011111) used in 8B/10B encoding to specify character alignment within a data stream. See also K28.5. Quickloop Fabric Assist User Guide 59

Chassis
The metal frame in which the switch and switch components are mounted.
Circuit
An established communication path between two ports. Consists of two virtual circuits
capable of transmitting in opposite directions. See also

.
Class 1
Service that provides a dedicated connection between two ports (also called
connection-oriented service), with notification of delivery or nondelivery.
Class 2
Service that provides multiplex and connection-less frame switching service between two
ports, with notification of delivery or nondelivery.
Class 3
Service that provides a connection-less frame switching service between two ports, without
notification of delivery or nondelivery of data. Can also be used to provide a multicast
connection between the originator and recipients, with notification of delivery or
nondelivery.
Class 4
Connection-oriented service that provides a virtual circuit between two ports, with
notification of delivery or nondelivery. Allows fractional parts of the bandwidth to be used
in a virtual circuit.
Class 6
Connection-oriented service that provides a multicast connection between the multicast
originator and recipients, with notification of delivery or nondelivery.
Class F
Connection-less service for control traffic between switches, with notification of delivery
or nondelivery of data between the E_Ports.
Class of Service
A specified set of delivery characteristics and attributes for frame delivery.
CLS
Close Primitive Signal. The protocol used by a port in an arbitrated loop to close a circuit.
Code Balance
The ratio of one bit to the total number of transmitted bits.
Comma
A unique pattern (either 1100000 or 0011111) used in 8B/10B encoding to specify
character alignment within a data stream. See also
