The Advanced Communications Controller (ACC) is a family of
high performance, multi-port, multiprotocol wide area network adapters
for HP 9000 computers. The ACC products support 2 or 8 V.35/V.36 connections,
2 or 8 RS232/X.21 connections or 4 T1/E1 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 the backup card in case
of failure.I
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.
The ACC X.25/9000 Link Software or X.25/ACC software subsystem provides
industry standard X.25 programmatic interfaces and services for
the ACC network adapter product. This manual provides information on
how to install and configure the X.25/ACC Subsystem, and how to bring
up and down network connections. It includes:
