150-359-100-01, Revision 01 Overview
HXU-359 List 1 October 27, 2000 1
OVERVIEW
The HiGain®Multiplexer Unit, HXU-359 List 1, is the SONET multiplexing
component of the Soneplex Wideband 3190. It can also be installed in the
HiGain Access Concentrator Express (ACE) chassis, a single-rack enclosure.
The HXU-359 multiplexes 28 DS1 lines into a single Synchronous Transport
Signal (STS-1) interface at a signal rate of 51.84 Mbps.
The Soneplex Wideband 3190 typically incorporates two HXU-359s, one
board functioning as the activeboard, the other as a standby. This redundancy
provides Automatic Protection Switching (APS). In the event of a failure, the
active HXU-359 relinquishes control to the standby HXU-359 within 50 ms.
Future enhancements to this product will support an optional Optical Carrier
(OC-3) interface and E1 interfaces.
FEATURES
•Complete software provisioning
•Advanced management using Terminal Access Option (TAO) or
Transaction Language 1 (TL1) software through a HiGain management
unit (HMU-319 List 7A)
•Virtual Tributary (VT) allocation of 28 DS1 line interfaces
•Flexible Time Slot Assignment (TSA) capability
•Software-selectable STS-1 and DS1 loopbacks
•In-service software upgrades
•Automatic and manual protection switching
•Performance monitoring and alarm logs
•Programmable DS1 line buildout
•Support for mixed T1 and E1 line interfaces
•Primary and secondary timing sources with multiple synchronization
options (dual BITS, DS1 interfaces, STS-1 interface, or internal clock)
•Optional Optical Carrier Level 3 (OC-3) interface
•Internal diagnostics testing

Overview 150-359-100-01, Revision 01
2 October 27, 2000 HXU-359 List 1
•Office dry-contact alarms (Major, Minor, Critical) under the control of
the HMU
•Front-panel status indicators
•Front-panel RS-232 craft port for direct connection to a maintenance terminal
COMPATIBILITY
The HXU-359 List 1 is compatible with Soneplex Wideband 3190
management shelves and the ACE-358 standalone enclosure.
If you are installing an HXU-359 in a Wideband 3190 that hasa different model
of HiGain multiplexer, contact Customer Service. Do not mix different models.
APPLICATION
The HXU-359 allows you to combine 28 DS1 lines into one high-speed STS-1
interface,thus providing a substantial cost savings over 28 individual DS1 lines.

INSTALLATION
Figure 4. Installing an HXU-359 Multiplexer Card
Before installing the HXU-359,visually check its packaging to
ensure that it has sustained no shipping damage.
Immediately report any damage to the shipping agent.
The HXU-359 multiplexer card can be damaged by
electrostatic discharge (ESD).
•Always wear an antistatic wrist strap connected to
equipment ground when handling the card. (The Soneplex
Wideband 3190 provides an ESD strap input above the
HMU slot and on the chassis backplane.)
•When working with the HXU-359, place it on an electrically
grounded antistatic mat.
•Properly store in antistatic packing material any HXU-359
that is removed from the Soneplex Wideband 3190 or
ACE-358.

6 October 27, 2000 HXU-359 List 1
HXU-359 multiplexer cards can be installed in a Soneplex Wideband 3190 or
a standalone ACE enclosure.
1For a Soneplex Wideband 3190, unscrew 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 on the chassis
(above the HMU slot on the Soneplex Wideband 3190).
3Set switches 3 and 5 on the SW2 switch block located on the circuit
board, behind the front panel.
•For an HMU-managed Soneplex Wideband 3190,set switches 3and
5 to the Off position (default settings).
•For a standalone ACE enclosure or to enable the HXU craft port, set
switches 3 and 5 to the On position.
4Align the edges of the card with the slot guides in the multiplexer tray.
5Grasping the card eject tabs, gently push the card into the bay.
6Firmly press in on the tabs until the card snaps into place.The LEDs flash
momentarily. The Power LED andActive LED on the active multiplexer
remain illuminated. The LEDs on the inactive (standby) multiplexer
should be off, except for the Power LED.
If you are installing an HXU-359 in a Soneplex Wideband 3190
that has a different multiplexer model, contact Customer
Service. Do not mix multiplexers in a system.
When installed in a working system that already has an
HXU-359, the second HXU is automatically configured for that
system by the active HXU in the shelf.

HXU-359 List 1 October 27, 2000 7
PROVISIONING
In a Soneplex Wideband 3190, the HMU-319 manages the HXU-359 by
using Terminal Access Option (TAO) software. When installed in the
ACE-358 chassis, the HXU-359 can also be provisioned directly from the
HXU craft port.
Refer to the Soneplex Wideband 3190 Installation Manual and the technical
practiceforthe HMU-319 List 7A forcomplete informationaboutconnecting
a maintenance terminal.
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
Soneplex Wideband 3190 and all its components. By connecting a local or
remote maintenance terminal to the HMU-319 List 7A, you can access the
craft port user interface for system provisioning and performance monitoring,
including the HXU. (Switches 3 and 5 on SW2 must be set to the Off position
to activate the HMU craft port and OSTS protocol.)
Figure 5 on page 8 shows the general structure of the TAO software. It
provides access to the maintenance terminal screens and to the HXU-359
management screens.
You can also directly connect the maintenance terminal to the
HXU if it has been activated as described in Step 3,
Installation, page 6. The default password for access to the
HXU screens when connected to the HXU craft port is
“public.”
For more information about the HMU, refer to the technical
practice for the HMU-319 List 7A and to the Provisioning
Reference section of the Soneplex Wideband 3190
Installation Manual.
