For information about line units, doublers, remotes and management units, refer to the appropriate
practice for the product model number.
The DC power supply feeds of the enclosure must be connected to either (1) -48 VDC SELV
sources or (2) -48 VDC sources which are electrically isolated from the AC sector and reliably
connected to earth. The source’s fault current capacity shall be lower than 50 A, or an
appropriate overcurrentprotection, rated5 A, must be provided on each -48Vdc conductor.The
overcurrent protection can also be used as a cut-off switch if another disconnect device is not
installed.
This equipment may be provided with a module that incorporates laser source(s). Refer to the
module’s documentation for detailed safety information.
The telemetry I/O must be connected to either a SELV source or a ELV source that is electrically

INTRODUCTION
DOCUMENT SCOPE
This guide provides basic step-by-step instructions for installing several different shelf configurations and
establishing a working system. Once you have completed the basic installation and verified that your system is
functioning properly, you can refer to the technical practices for the individual components. The technical
practices provide comprehensive configuration and technical information that will help you further define system
parameters to meet your particular system requirements.
To use this practice:
•Follow the steps provided in the order in which they are presented, beginning with the section entitled “Before
You Begin”on page 3.
•Tabbed sections are provided for chassis cabling and multiplexer installations. Based upon your choice of
multiplexer and chassis configuration, select the sections that apply to your system installation.
•Place a check mark after each installation task you complete, and then sign your name in the places indicated
after each section you complete.

SYSTEM OVERVIEW
Figure 1. System Overview
The Soneplex Wideband System 3190 (HMS-357 List 4 and List 5) is an open-standards system that provides
complete T1 and E1 deployment. Depending on your choice of multiplexer, the HMS-357 can transport T1 or E1
interfaces to filedlocations from T1, E1, DS3, STS-1, or OC-3network connectors. The system can accommodate
up to 28 industry-compliant 3192 line cards, an optional fan assembly, and two multiplexers under the control of
a management unit (HMU). Both Terminal Access Option (TAO) and Transaction Language 1 (TL1)
management systems are supported.

HMS-357 List 4 and List 5 September 29, 2000 3
BEFORE YOU BEGIN
Prior to installing the Soneplex WBS-3190, it is important to prepare for the installation by
•Reviewing installation plans through establishing a Method of Procedure
•Unpacking and inspecting the system components, and
•Gathering the tools for the installation
REVIEWING INSTALLATION PLANS
Installation personnel, engineers, and Central Office (CO) supervisors, involved in the installation of the
HMS-357, should participate in the preparation of a Method of Procedure (MOP) for approval by CO
management.
ESTABLISHING AMETHOD OF PROCEDURE
Following is a list of tasks and considerations that need to be addressed and mutually agreed upon before
proceeding with installation:
•Assignment of personnel
•Installation tools and methods
•Protection requirements for personnel, equipment, and tools
•Evaluation of potential hazards that may affect service
•Scheduled time for installation
•Space requirements (see “Power Requirements”on page 81)
•Power requirements (see “Power Requirements”on page 81)
•Identification of procedures and tests required before connecting to working equipment
•Identification of work steps and any necessary notifications to CO personnel or engineers before work begins
•Assignment of individual system IDs for up to 32 managed systems
(see “Setting the Shelf Identifier (Option D)”on page 30)
•Assignment of IP addresses for each installed system
(see “Setting the Shelf Identifier (Option D)”on page 30)
