LTPH-TP-1044-01, Issue 1 Overview
HXU-358 V1.04 April 6, 2001 1
OVERVIEW
The HiGain®Multiplexer Unit, HXU-358 V1.04, is the multiplexing
component of the Soneplex®Wideband 3190 system. It can also be installed
in the HiGain Access Concentrator Express (ACE) chassis, a single-rack
enclosure (see “Appendix B - HXU-358 Installation for ACE Chassis”on
page 53 for more information). The HXU-358 multiplexes 28 DS1 lines into
a single Digital Signal, level 3 (DS3) interface at a signal rate of
44.736 Mbps.
The Wideband 3190 typically incorporates two HXU-358s, one board
functioning as the active board, the other as a standby. This redundancy
provides backup protection. In the event of a failure, the active relinquishes
control to the standby HXU-358 within 50 ms.
FEATURES
•Complete software provisioning
•Advanced management using Terminal Access Option (TAO) or
Transaction Language 1 (TL1) software through an HMU-319
•Advanced internal test head functionality for DS1/E1 line testing and
fault sectionalization
•Digital Acess Cross-connect (DACs) switching at the DS1/E1 level
•Software-selectable DS3 local and network loopback
•DS1 line code and loopback options
•Downloadable software
•Automatic and manual protection switching
•Password protection
•Internal and external diagnostics testing
•Dry contact alarm relay
•Office alarms (Major, Minor, Far-End, Critical)
•Front-panel status indicators
•Support for T1 and E1 line interfaces

Overview LTPH-TP-1044-01, Issue 1
2 April 6, 2001 HXU-358 V1.04
•Digital Access Cross-connect Switching (DACS)
•Front-panel test jacks for external test access as well as a backplane test
interface
•Front-panel RS-232 craft port for direct connection to a maintenance terminal
•Support for an external fail-safe alarm
COMPATIBILITY
The HXU-358 is compatible with Wideband 3190 (HMS-357 and HMS-358)
managed shelves as well as HiGain ACE chassis, single-rack enclosures.
If you are installing an HXU-358 in a Wideband 3190 or ACE
chassis that has a different multiplexer model, contact
Customer Service (see “Appendix D - Service and Support”
on page 59). Do not mix multiplexers in a system.
Do not mix multiplexers of differing software revision levels
unless specifically directed, doing so activates a software
mismatch alarm. This alarm indicates that software versions
are incompatible for long-term operation. Transfer of
configuration information is performed.

LTPH-TP-1044-01, Issue 1 Overview
HXU-358 V1.04 April 6, 2001 3
APPLICATION
The HXU-358 allows you to combine up to 28 T1 lines or up to 21 E1 line
into one high speed DS3 interface, thus providing a substantial cost savings
over transporting 28 individual HDSL/DS-1 lines through a carrier’s
network.

HXU-358 INSTALLATION FOR
WIDEBAND 3190 OR ACE SYSTEMS
The following sections document HXU-358 installation procedures for
Wideband 3190 (HMS-357 and HMS-358) and ACE (ACE-Com, List 1)
systems.
Before installing the HXU-358,visually check itspackaging to
ensure that it has sustained no shipping damage.
Immediately report any damage to the shipping agent.
The HXU-358 multiplexer card can be damaged by
electrostatic discharge (ESD).
•Always wear an antistatic wrist strap connected to
equipment ground when handling the card.
(The Wideband 3190 provides an ESD strap input above
the HMU slot and on the chassis backplane.)
•When working with the HXU-358, place it on an electrically
grounded antistatic mat.
•Properly store in antistatic packing material any HXU-358
that is removed from the Wideband 3190.

Figure 4. Installing an HXU-358 Multiplexer Card
HXU-358 multiplexer cards are installed in the front of the Wideband 3190
or ACE chassis.
1Unscrew the two hold-down lugs on each side of the chassis front cover.
The cover folds down.
2Connect your ESD wrist strap to the ESD strap input above the HiGain
Management Unit (HMU) slot or above multiplexer slot A in the ACE.
An ESD touchplate is integrated on top of the card’s front panel for
added anti-static protection.
3Align the edges of the replacement card with the slot guides in the
multiplexer tray.
4Grasping the card eject tabs, gently push the card into the bay.
5Firmly press in on the tabs until the card snaps into place.
If you are installing an HXU-358 in a Wideband 3190 that has
a legacy multiplexer (HXU-357), contact Customer Service. A
mixed system is not allowed.

When the card snaps into place, power is supplied to the unit and the
LEDs flash momentarily. The PWR LED and ACTIVE LED on the
active multiplexer remain illuminated. The LEDs on the inactive
(standby) multiplexer should be off, except for the PWR LED.
If you are replacing a HiGain Multiplexer Unit (HXU) in a
working system, the standby replacement HXU-358 is
automatically configured for that system by the active
HXU-358 in the shelf.

LTPH-TP-1044-01, Issue 1 Provisioning
HXU-358 V1.04 April 6, 2001 9
PROVISIONING
Using Terminal Access Option (TAO) management software, the HMU-319
configures and manages the HXU-358.
Refer to the Wideband 3190 installation guide and the technical practice for
the HMU-319 for complete information about connecting a maintenance
terminal.
For installation in ACE chassis, see “Appendix B - HXU-358 Installation for
ACE Chassis”on page 53.
Also, refer to your Central Office (CO) system plans for provisioning details.
ACCESSING THE MANAGEMENT INTERFACE
The HiGain Management Unit interface presents the user with an interactive,
text-based, menu-driven interface that configures, monitors, and controls a
Wideband 3190 and all the components that it comprises. By connecting a
local or remote maintenance terminal to the HMU-319, yougain access to the
craft port user interface which displays menus and prompts to guide you
through a provisioning process. This process involves:
•Logging On To the System through the HMU (see page 10)
•Selecting a Shelf (see page 11)
•Configuring the HMU to Access the HXU-358 (see page 11)
•Accessing HXU-358 (see page 12)
Figure 5 on page 10 shows the general structure of the TAO software. It
provides access to the HLU maintenance terminal screens and to the
HXU-358 software interface.
If you would likemore information about the HMU, refer to the
technical practice for the HMU-319 or the Provisioning
Reference section of the Wideband 3190 Installation Guide.
