May also refer to the range of transmission frequencies available to a network. Buffer-to-buffer credit; the number of frames that can be transmitted to a directly connected recipient or within an arbitrated loop. Determined by the number of receive buffers available. See also Buffer-to-buffer Flow Control, EE_Credit. The disparity at the transmitter or receiver when the special character associated with an ordered set is encoded or decoded. See also Disparity. AW_TOV Bandwidth BB_Credit Beginning Running Disparity Advanced Performance Monitoring User's Guide Glossary-1 BER Block Broadcast Bit Error Rate; the rate at which bits are expected to be received in error. Expressed as the ratio of error bits to total bits transmitted. As applies to Fibre Channel, upper-level application data that is transferred in a single sequence. The transmission of data from a single source to all devices in the fabric, regardless of zoning. See also Multicast, Unicast. Buffer-to-buffer Management of the frame transmission rate in either a point-to-point topology or Flow Control in an arbitrated loop. Cascade Two or more interconnected Fibre Channel switches. For HP switches, a maximum of seven hops is recommended (no path longer than eight switches). The metal frame in which the switch and switch components are mounted. An established communication path between two ports. Consists of two virtual circuits capable of transmitting in opposite directions. Service that provides a dedicated connection between two ports (also called connection-oriented service), with notification of delivery or nondelivery. Service that provides multiplex and connectionless frame switching service between two ports, with notification of delivery or nondelivery. Service that provides a connectionless 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. Connectionless service for control traffic between switches, with notification of delivery or nondelivery of data between the E_Ports. [. . . ] Arbitrated loop - Multiple NL_Ports connected in a loop. A mode in which private devices can communicate with public devices across the fabric. A 10-bit character encoded according to the rules of the 8B/10B algorithm. A group of four transmission characters. The message sent by an SNMP agent to inform the SNMP management station of a critical error. [. . . ]
