INTRODUCTION

he WaveStar ADM 16/1 is a

T

high-capacity intelligent
multiplexer and transport system
able to multiplex PDH, SDH,
SONET and EtherNet bit rates to
higher levels up to 2.5 Gbps
(STM-16). Because of this wide
range in capacity, this system is a
key element in building efficient
and flexible networks.

The main strengths of the product
are:

· Massive add/drop capacity
directly from the
STM-16 level e.g. 504 x E1,
96 x DS-3,
64 x 10/100 BASE-T, 32 x
STM-1 etc.

· Compact design (single row).

· Easy installation &
maintenance.

· Flexibility in applications.

· Advanced protection
mechanisms allowing
state-of-the-art SDH network
design.

These outstanding features make
the WaveStar ADM 16/1 one of
the most cost-effective future­proof network elements. The
system can be deployed with
other Lucent Technologies optical
networking products, making the
WaveStar ADM 16/1 one of the
main building blocks of future
SDH networks.

The WaveStar ADM 16/1 is
controlled and managed by
Lucent Technologies Integrated
Transport Management (ITM), a
user-friendly network and
element level management
system with in-service upgrade
facilities.

APPLICATIONS

he WaveStar ADM 16/1 is a

T

single product platform for
STM-16, STM-4 and STM-1
applications. Based on its
flexibility with regard to interface
units and cross-connect
capabilities, the system supports
applications for bandwidth
access, service-on-demand and
network protection.

The WaveStar ADM 16/1 can be
applied in two tiers of the
network: access & regional
networks. The system allows for
growth and changing service
needs by supporting in-service
conversions and upgrades.
Inherent to its basic design, the
WaveStar ADM 16/1 operates
equally well within fully
synchronous as well as
asynchronous environments and
provides a flexible link between
the two.

The WaveStar ADM 16/1 supports a
large variety of configurations for
various network applications (see
Figure 1):

· Terminal for point-to-point
connections.

· Ring add/drop multiplexer or
STM-4 and 16 rings.

· Access mux to DWDM, 10G,
cross-connect & SONET.

· Hub mux of STM-1 and STM-4
rings to STM-16.

· Grooming of lower-order VCs.

· PDH front-end for digital cross­connect systems.

· Single ADM 16/1 for
interconnection of STM-16,
STM-4 and STM-1 rings
(Ring Closure on tributary
side).

· TransLAN-functionality for
10/100 BASE-T Ethernet
signals.

Traffic can be protected by:

· Path protection: VC-n SNC/N.

· Section protection:

 MS-SPRing, MSP.

· Dual Node Interconnection
(DNI).

PRODUCT DESCRIPTION

his flexible product resulted

T

from a big step forward in
technology. Due to the high level
of integration at the circuit pack
level, it is possible to add/drop up
to 504 x E1/DS1, 48 x E3,
64 x 10/100 BASE-T, 96 x
DS3/STM-0, 32 x E4/STM-1/OC­3 or 8 x STM-4/OC-12 using only
one subrack. One rack with a
height of 2400 and 2600 mm,
can accommodate two subracks.
The heart of the WaveStar ADM
16/1 system is the Cross­Connect, which has connections
with all interface cards (see
Figure 2). The Cross-Connect is
the core of the system.

It enables the flexible routing of VC-4,
VC-3 and VC-12 between:

· Aggregate and aggregate.

· Aggregate and tributary.

· Tributary and tributary.

To contribute to overall system
reliability and availability, the
Cross-Connect can be protected
by an accompanying unit. If
required, interface redundancy
can be provided. The flexible
design of the WaveStar ADM
16/1 makes it possible to place
interface units in almost any
interface slot position of the
subrack. The System Controller
(SC) unit controls all major
functions of the WaveStar ADM
16/1 and communicates with the
centralized management system
(ITM). Communication is
established via the Data
Communication Channels within
the STM-N section overhead
signals or via one of the Q­interfaces of the system. The
ITM-SC manages the WaveStar
ADM 16/1 at the element level
and the ITM-NM can manage the
system at the network level. The
ITM-Craft Interface Terminal
(ITM-CIT) is used for managing
small networks and for
maintenance purposes.

The system is synchronized by an
optionally duplicated Power and
Timing generator circuit pack.
Both 2048-kHz and 2048-kbps
synchronization interfaces are
supported. References can be
selected by and prioritized from
among the synchronization
interfaces, STM-N interfaces and
2-Mbps tributary interfaces.
Reference protection is possible
by enabling the ETS 300 417-6
compliant synchronization
message protocol which uses the
S1-byte information (SSM
support).
