Avaya P550R/P580/P880/P882 Multiservice Switch ATM Uplink Module User Guide, Version 2.0
The end-to-end connection, either point-to-point or point-to-
multipoint, between two endstations. Consists of one or more
Virtual Channels (VCs) concatenated together.
A 16-bit identifier in each ATM cell header that identifies the virtual
connection associated with the cell. Each VCI value has local
significance to only one ATM port in an Avaya system.
A portion of a virtual path or virtual channel that is used to establish
a single virtual connection between two endpoints.
A non-physical Ethernet connection created by the network
between an Avaya system and an endstation, based on the
endstation ID and the Avaya system node name.
A network paradigm that interconnects users based on relationships
instead of physical location. Physically consists of one or more
virtual switches and all attached endstations. Logically consists of
one or more virtual LANs.
A group of virtual channels that can support multiple virtual
circuits.
An 8-bit identifier in each ATM cell header that identifies the virtual
path associated with the cell. Each virtual path can support up to
64K virtual channels.
Part of a network that also consists of Virtual LANs (VLANs).
A collection of (P) VCs on the same ATM Uplink module, all bound
to the same VLAN. Functionally, a VSP take the place of the BUS
and LEC (LANE) in that it replicates flooded (broadcast/
unknown)packets to all VCs in a broadcast domain and learns the
VC-relative location of all end-stations.
