Product Features

The ACC Product provides a family of network interface cards for HP9000 systems and workstations:

8-channel HP-PB (NIO)ACC Mux port transmits at speeds up to 76.8 Kbits per second (Kb/s).
8-channel EISA ACC Mux port transmits at speeds up to 128 Kbits per second (Kb/s).
8-channel PCI ACC Mux port transmits at speeds up to 2.048 Mbits per second (Mb/s).
2-channel HP-PB (NIO) ACC Multiplexer product transmits at speeds to 2.048 Mb/s on either channel and 2.2 Mb/s cumulatively on both channels.
4-channel HP-PB (NIO) T1/E1 ACC Multiplexer product transmits at speeds to 2.048 Mb/s on E1 ports and 1.544 Mb/s on T1 ports.

The ACC Product provides a high-connectivity solution with:

Up to eight network connections on a single network interface board
Remote node capability that allows programmatic requests to be routed to either a multiplexer card that is connected to the system on which the request was made, or to a multiplexer card on a remote system.
Up to 128 subchannels on a single 4-channel interface board.

Highly available solutions can be created using the ACC product by making use of:

Dual interface panels and/or cabling configurations that allow two systems to connect to a single network access point.

Highly flexible solutions may be created using the ACC product:

Multiple protocols are supported. The ACC Protocols for Application Developers product provides all the supported protocol modules.
The ACC supports multiple protocols, combinations of protocols, and data communications speeds simultaneously on different ports of the same ACC multiplexer card.
Custom protocols may also be developed.
The ACC Protocols for Application Developers product provides the protocol independent programmatic interface routines to support 32-bit and 64-bit C application development. These routines are thread-safe and support true multi-threaded applications.
Physical interfaces such as RS-232, RS-449, V.35 and X.21 are supported, as well as RJ45, S2M, BNC and DB-9 for the 4-channel interface.
