abstract syntax notation 1 (ASN.1)
A complex data description language used for defining data in a machine-
independent manner. ASN.1 is defined in ITU-T and ISO specifications.
ACC
See
access call control (ACC) (page 6)
acceptable routing path
A path that satisfies the traffic requirements for an ATM PNNI call and for
which the optimization metric is within the specified variance interval.
Acceptable routing paths are used for ATM network load balancing.
access call control (ACC)
Nortel Multiservice Switch protocol-independent software that controls the
progress and state of a call.
access delay
The time it takes to clock a frame or cell into or out of an access port on a
Nortel Multiservice Switch node. In a Multiservice Switch network, the
calculated value for access delay includes the serialization delay only. Access
devices are assumed to be located close enough to a Multiservice Switch
node so that propagation delay is ignored.
access module (AM)
A DPN-100 device that provides user access, termination, and concentration,
and local data switching. Access modules can use Nortel Multiservice Switch
nodes as a backbone device.
access protocol control (APC)
Software residing on a Nortel Multiservice Switch node. APC software support
OSI Layers 1, 2, and 3 CCS message handling and call processing functions
for connections with PBXs. See also
common channel signaling (CCS)
accounting gateway
A software application that runs on a workstation and is used to convert
accounting records into a format usable by an IBM or VAX billing host.
accounting meter
Collects data for the frame relay egress accounting and ATM accounting
features based on the end-user traffic at the entry and exit points of the
networks. The meter generates accounting records from the collected data.
acknowledgment
A message that the receiving end sends to the source to indicate that it has
received a transmission in good order.
