Introduction
1.1 Using This Guide
The µSDM-1 Installation Operation and Maintenance Manual (IOM) is intended to
provide the information necessary to install, configure, operate, maintain and
troubleshoot the family of µSDM-1 multiplexer systems. You can also use it to learn
more about the µSDM-1’s mechanical, electrical and operational characteristics.
Each subject is dealt with in a separate chapter. You can therefore use this manual as
a reference guide for obtaining only the information that you need, or you can read it
from cover to cover to gain a broader knowledge of the µSDM-1 systems.
1.2 System Overview
The µSDM-1 miniature Access multiplexers create a direct link between the SDH
backbone and Access networks. It provides an end-to-end, fully managed network
solution from the exchange to the customer’s premises. The product range includes:
♦ µSDM-1RD — Slim multiplexer in a reduced version.
♦ µSDM-1 — Slim multiplexer, in a standard version.
♦ µSDM-1E — Extended multiplexer.
The µSDM-1 operates at the STM-1 (155 Mbit/s) line rate and enables high end-user
service availability. It is an integral member of Lightscape Networks future-oriented
transmission network and is fully compatible with the entire SYNCOM™ SDH and
Broadgate network product family and associated equipment.

Introduction µSDM-1RD / µSDM-1 / µSDM-1E IOM
1-2 Lightscape Networks Ltd. Proprietary 426006-2304-013-B1
1.3 System Applications
The µSDM-1 is aimed at the Access fixed or mobile Network as it evolves from
traditional PDH-based technology to the benefits offered by SDH transmission
solutions. Typical µSDM-1 Access network applications include:
♦ Fiber to the Curb (FTTC) - Street cabinet installations incorporating Access
equipment and Remote Switching Units (RSUs).
♦ Fiber to the Building (FTTB) - Basement or exchange installations
distributing voice and data traffic to local subscribers.
♦ Fiber to the Office (FTTO) - For corporate users including banks and medium
to large companies.
The µSDM-1 serves as a network termination connected to the customer’s PABX,
LAN etc.
Fiber to the base station subsystem (BSS) units. Interconnection of base station
transceivers (BTS) to the base station controllers (BSC) Interconnection of base
station controllers (BSC) to the Monte switch (MSC)
The µSDM-1 provides direct multiplexing and demultiplexing for the following
tributary signal interfaces:
8/21 x 2 Mbit/s (Reduced/Basic unit)
63 x 2 Mbit/s (Extended unit)
3 x 34 Mbit/s (Extended unit)
3 x 45 Mbit/s (Extended unit)
The µSDM-1 multiplexer supports local and network level management systems via
Lightscape Networks Element Management (eEM), and Network Management
(eNM) workstations or at the network level from a Telecommunication Management
Network (TMN) workstation.

1.5 Additional Assistance
The installation and operation of a multiplexer and its configuration for network
operation is a highly specialized process. Due to the different nature of each
installation and the special concerns of any facility, there may be aspects of
installation planning that are not covered in this guide.
If you have questions or concerns about your network design, or if you require
installation personnel to perform the actual installation process, Lightscape
Networks maintains a staff of design engineers and a sizable team of highly trained
field service personnel. The services of the group are available to customers at any
time. If you are interested in obtaining design assistance or a network installation
plan from Lightscape Networks Customer Support team, contact your Lightscape
Networks sales representative.
With any support related issues, technical or logistic, please contact the Lightscape
Network customer support center at your location. If you are not familiar with that
location, please contact our central customer support center action line at:

Product Description
SYNCOM™ SDH equipment is designed with a cost effective, modular
architecture, enabling easy system upgrading and reconfiguration by simply adding
or replacing the modular units. All cards have their own built-in power supplies and
adding or replacing a single module is simple and can be done while the system is
operating.
Most of the network element cards are fully interchangeable between the various
multiplexer types, providing a family of products that are completely compatible
with one another. Further module specifications can be found in Chapter 7 of the
µSDM-1 General Description.
2.1 Equipment Options
The µSDM-1RD/µSDM-1/µSDM-1E is fully factory configured and does not
include any user-replaceable parts apart from the TEX expansion cards. Unlike other
SYNCOM™ products, all the µSDM-1RD/µSDM-1/µSDM-1E hardware options are
pre-installed for each multiplexer configuration alternative.
There are three µSDM-1 multiplexer models:
1. The µSDM-1RD is the reduced version of the product. It supports up to eight
E1 tributaries and is non-expandable.
2. The µSDM-1 is the standard multiplexer. It supports up to 21 E1 tributaries.
3. The µSDM-1E module is upgradable from 21 E1 to 63 E1 tributary
interfaces via Tributary Expansion (TEX) cards. Adding a TEX card causes
no interruption to live network traffic and can be performed at any time.
TEX expansion cards can only be installed with µSDM-1E multiplexers and include
interfaces for 2 Mbit/s expansion, 34 Mbit/s or 45 Mbit/s tributary support.
Figure 2-1 shows µSDM-1 and µSDM-1E multiplexer hardware options.

2.2 Upgrade Paths
Changing the NE’s operational functionality can be done by a remote download of
new software to the NVM card (via the network management station). Like all
SYNCOM™ products, the NVM flash-card can store two software versions to
enable reversible upgrades.
Special services (e.g., data communications) can be added at any time installing
Tributary Expansion (TEX) cards to the basic unit. This, without having to upgrade
the basic hardware to add system functionality.
