The Multiprotocol Advanced Communications Controller (ACC)
is a family of high performance, multi-port Multiprotocol wide area
network (WAN) adapters for HP 9000 computers. The ACC products support
two or eight RS232/V.35/RS449/X.21 connections, or four E1/T1 connections on
a single HP-PB, EISA, or PCI network interface board..
HP's ACC
supports one or multiple protocols on a single card. Supported protocols
include:
With
the ACC, systems may be configured for card-level or system-level load
sharing or redundancy for single-site and multi-site operations.
For card-level redundancy, a system can be configured with two cards
that connect to one “dual connect” distribution panel.
This allows a network connection to be programmatically assigned
to one of the two cards and switched to one of the two cards and
switched to the backup card in case of failure.
For system-level redundancy,
two systems with ACC cards, either local or remote, may be configured
using “dual connect” distribution panels such that
if one system can no longer receive traffic, the traffic is routed
to a second system.
