Multiplexer Overview
The Advanced Communications Controller (ACC) Subsystem is an
intelligent serial communication product for HP e3000 Workstations
and Servers. It provides a high performance Wide Area Network (WAN)
platform for customers who have large synchronous and asynchronous
networks. A complete HP ACC subsystem consists of both the
multiplexer hardware and ACC software. This manual describes the
8-port PCI ACC Multiplexer hardware. This multiplexer is compatible
with the Peripheral Component Interface (PCI) format. Refer to the
manuals provided with your ACC software products for information on
the ACC software.
Multiplexer Features
The major features of the HP multiplexer are:
• Serial communications at high speeds.
• Ideally suited for Wide Area Networks (WAN).
• Data rates configurable up to 128k baud on RS-232 and V.35 ports.
• Synchronous support.
• Support of the following telecommunications protocols:
— LAPB
— HDLC normal mode (SDLC)
— HDLC-Level 1
• Level 1 support for RS-232 and V.35.
• Each port can be set to the following modes.
— RS-232
— V.35
— Differential Loopback

Multiplexer Overview
8-Port PCI Multiplexer Maximum Baud Rates
Although the ACC MUX card can handle rates above 19.2 Kbps for
RS-232 and 64 Kbps for V.35, it is the customer’s responsibility to
ensure that the cable type and length are chosen appropriately.
Per Port RS-232 128 Kbps
V.35 128 kbps
Aggregate RS-232 1024 Kbps
V.35 1024 kbps
Multiplexer Architecture
The 8-port PCI ACC Multiplexer is an intelligent microprocessor-based
interface that supports a wide variety of serial data communication
protocols. The architecture allows the protocols to be implemented as
downloaded modules which enhance the flexibility of the interface. The
multiplexer has sufficient memory to provide data buffering and
configuration tables, as well as space for multiple downloaded protocol
modules. Figure 1-1 shows a functional block diagram of the
multiplexer card.

Overview
Multiplexer Overview
Multiplexer Hardware Requirements
The 8-port PCI ACC multiplexer consists of the major hardware
components described in Figure 1-2 and shows the components and how
they combine to provide the functionality of the ACC subsystem.
Figure 1-2 HP Z7340A 8-Port PCI ACC Card with Interchange Panels
NOTE Interchange panels and cables are not included with the Z7340A 8-port
PCI ACC product. These must be ordered separately. Refer to the
section on “Accessories” for a list of interchange panel and cable
products.
Multiplexer
The multiplexer (or MUX) installs as an I/O interface card in the
HP e3000 computer. The MUX is a one-half length PCI card, which
supports eight synchronous or asynchronous ports at speeds up to
128 Kbps on RS-232 and V.35 ports.
Interchange Panel
An Interchange Panel acts as an intermediary between the MUX and
the Packet Switching Network (PSN). Each individual interchange
panel is designed for a specific serial communications standard, such as
RS-232, and V.35 specifications.
Rack Mounting Plate
A rack mounting plate allows up to two interchange panels to be
mounted in the HP e3000 computer system’s rack. Panels can be
mounted in any orientation.

HP Z7325A MUX/Interchange Panel Cable
The MUX connects to the interchange panel by a 160-conductor
(28 AWG) cable, three meters (10.77 feet) in length. The cable has male
connectors on each end, refer to Figure 1-3. The signals for each of the
pins are listed in Appendix A , “Interchange Panels.”
Figure 1-3 HP Z7325A Cable Connector (Male)
Octopus Cables
Two-meter octopus cables with a 160-conductor connector on one end
and eight RS-232 or V.35 female connectors on the other end are also
available for connecting the MUX and the Packet Switching Network.
This cable replaces the 160-conductor cable and interchange panels for
RS-232 or V.35 connections. Figure 1-4 shows the MUX card with an
octopus cable.
NOTE The octopus cables do not support dual configuration (high-availability
systems). You must use the 160-conductor cable and interchange panel
to implement the dual configuration feature if you require an highly
available system.

Overview of the Interchange Panels
The Multiplexer is designed to connect to an interchange panel, which
“breaks out” the signal into the ports. These panels are “passive”
distribution panels, accepting the input from the MUX and distributing
it to the network.
This section describes the various models of interchange panels that
are compatible with the 8-port PCI ACC product. Each interchange
panel is designed for a specific serial communications standard.
The following interchange panels that are compatible with the 8-port
PCI ACC Multiplexer. Individual illustrations for each of the
interchange panels appear later in this section.

Unpacking and Handling
Unpacking and Handling
If evidence of damage is observed when the carton containing the
product is opened, inspect all items carefully, keep the shipping carton
and packing material for the carrier’s inspection.
If any item appears to be damaged, or if the product does not pass
verification procedures described in this chapter, notify the nearest HP
Sales and Support Office. Arrangements for the repair or replacement
of the defective item(s) will be made without waiting for settlement of
possible claims against the carrier.
Save the shipping carton and packing material after unpacking the
product. These will be useful in the event that any item must be
returned to Hewlett-Packard.
WARNING Before installing the ACC Multiplexer, be sure to refer to the
computer’s manual that details the installation of accessories.
To avoid severe personal injury, pay particular attention to
Warnings and Cautions related to hazards exposed when
opening covers in the computer. Because of the risk of electric
shock or exposure to high-energy (high-amperage) circuits,
some computers require that accessories be installed by
persons qualified in the installation and servicing of computer
equipment and who are trained to recognize the hazards
involved.
