Alcatel 1642 Edge Multiplexer
155-to-622-Mbit/s Alcatel OMSN for customer premises & public/private companies
The Alcatel 1642 EM is a multiservice CPE that highlights
Ethernet/Fast Ethernet ports with Layer 2 Ethernet switching
functions to enable both point-to-point (E-line) and multipoint
(E-LAN) Ethernet services.
The Alcatel 1642 Edge Multiplexer (EM),
part of the Alcatel Optical Multiservice
Node (OMSN) family, is an ideal spacesaving, next generation multiservice
building block for customer premises and
business locations. It enables business,
residential and mission-critical communications in the metro network, providing
unmatched performance for its size.
The primary applications for the
Alcatel 1642 EM product are found in
the following areas:
> Delivery of QoS-based Ethernet and
TDM services to customer premises
and business locations
> Local and metropolitan rings
> Point-to-point links with intermediate
drop/insert and/or regeneration stations
> Always-on, mission-critical
communication
COST-EFFECTIVE CPE FOR
MULTISERVICE OPTICAL ACCESS
The extension of SDH benefits to customer
premises and business locations has become
an established concept. Installation of compact optical equipment (CPE) for leasedline and public/private-company services to
medium and large businesses is a reality in
many access networks. The benefits can be
summarized in the extensive end-to-end
path control and monitoring capabilities
offered by SDH networks. It is worthwhile
adopting SDH technology even for the
delivery of Ethernet services, bringing the
benefits of SDH to the transport of data
services. The variety of existing and future
interfaces and services can be easily mapped
into the SDH transport layer, adding the
reliability and flexibility of SDH transport
and providing a future-safe investment in
new services.
ETHERNET VPN SERVICES
AND LAN INTERCONNECTION
Data-aware features integrated into the
Alcatel OMSN family through integrated
service adapter (ISA) plug-in modules
fully address the technical requirements
of today’s service providers, as well as the
expected need to provide telecom operators
with the latest, future-safe optical provisioning platforms.
The Alcatel 1642 EM features an
Ethernet/Fast Ethernet card for the
transport of reliable frame-based data
interconnections in point-to-point, pointto-multipoint and shared-bandwidth ring
applications. The capability to map Ethernet
flows into multiple SDH resources using
virtual concatenation dramatically boosts
the survivability of the user data connection in the event of a network failure.
ISA-ES1 blades can be hosted in the
Alcatel 1642 EM and enable carrier-class
Ethernet VPN and aggregation services
in the metro network.
Alcatel 1642 Edge Multiplexer — 155-to-622-Mbit/s Alcatel OMSN for customer premises & public/private companies
Beyond mapping business and industrial Ethernet
flows onto SDH network resources through standardized
mechanisms such as GFP/LAPS, VCAT and LCAS (as
specified in ITU G.7041, ITU G.7042 and ITU G.707), the
ISA-ES1 series cards introduce wire-speed classification,
policing and scheduling capabilities on a carrier-class
Ethernet switching blade.
Per-customer traffic flow management with low bandwidth granularity, traffic segregation and per-flow QoS
mechanisms are supported to enable service-oriented
Ethernet networking. Two different blade options are
available for the ISA-ES1 to meet the required capacity
and features, providing the best cost-optimized Ethernet
solution for different networking applications:
> ISA-ES1 3-port version, offering 2 x FE electrical plus
1 x FE optical ports on board, providing 155 Mb/s
backpanel capacity and featuring GFP, VCAT, LCAS,
VLAN/Q-in-Q with QoS support.
> ISA-ES1 8-port version, offering 8 x FE electrical ports
on board, with the same features as the 3-port version.
Through the integration of Ethernet-switching capability
on Alcatel 1642 EM Ethernet cards, not only point-topoint, but also point-to-multipoint applications and sharedbandwidth rings can be implemented. The resources
required to connect several customer and business sites
to provide Ethernet LAN interconnection services are
drastically reduced.
Network-infrastructures owner must manage and
transport new Ethernet-based revenue-generating value
added services (VAS) at the lowest cost per bit, especially
in the access network, where bandwidth is limited. The
shared-bandwidth ring allows sharing of bandwidth
between multiple users who are accessing the ring, using,
for example, only 1 x VC-3 on each link for Ethernet
traffic and leaving enough bandwidth for other revenuegenerating services.
The Alcatel 1642 EM’s Ethernet card gives service
providers and public/private companies an optimized
solution for providing Ethernet LAN interconnection
services with incremental investments, exploiting the
existing SDH infrastructure, thus avoiding the need to
deploy a new overlay infrastructure, ultimately reducing
both CAPEX and OPEX.
COMPACT, FLEXIBLE, DATA-ORIENTED, FUTURE-SAFE
The Alcatel 1642 EM is based on 2 x STM-1/4 (155 to
622 Mbit/s) line interfaces, up to 18 STM-1 equivalents
full non-blocking HO SDH matrix and 12 STM-1 equivalents full non-blocking LO SDH matrix, clock reference
and equipment control functions, all concentrated in a
1-slot wide compact card.
The equipment’s shelf is physically formed in four
parts: a middle-lower area where a main control board
holds an STM-1/4 ADM, the upper part with up to four
upper tributary boards and the left and right parts
hosting the fan and power-access board.

The system may be configured as an STM-1 add drop
multiplexer (ADM) with a termination capacity of up to
112 x 2 Mb drop for metropolitan networks or as an STM-4
multiservice terminal multiplexer with 2 x STM-1 and
8 x E/FE interfaces, used to link several large offices to
an enterprise network.
The Alcatel 1642 EM has a symmetrical architecture,
allowing its application as terminal multiplexer, add-drop
or mini cross-connect in spur, multiple rings or meshed
topologies. All traffic ports (PDH, Ethernet or SDH) of
the same type have the same functionality and behavior
and there is no inherent split between tributaries and
aggregates.
The Alcatel 1642 EM’s resiliency makes it ideal as a
multiservice transport node. In terms of hardware, the
Alcatel 1642 EM has a centralized control architecture
that limits the presence of processors and software to
the compact ADM-1/4 card. Traffic ports have no onboard processors and may be reused from one piece of
equipment to another, or retrieved from stocks without
concern about software versions. The Alcatel 1642 EM
also offers local and remote software downloads. In addition, service providers can also monitor subnets formed
by the Alcatel 1642 EM, even in multivendor networks.
Whether in telecommunications-office environments or
at enterprise locations, the Alcatel 1642 EM has the right
powering solution (DC or AC) and optional power
redundancy can provide equipment protection.
Concerning traffic protection, sub-network connection
protection (SNCP) with drop-and-continue function is
provided for improved traffic availability, enabling the
Alcatel 1642 EM to be inserted directly into access rings
or to be connected to access rings via point-to-point,
unprotected or protected links. SNCP also enables endto-end protection of SDH paths. Dual hubbing to two
distinct central-office transport nodes is also possible,
e.g., via dual STM-4 uplinks.
The Alcatel 1642 EM paves the way to build unique
optical-network infrastructures, supporting optimized
transport and integrated networking functions for data
applications, such as new Ethernet VPN services.
The Alcatel OMSN family consolidates the vast experience gathered by Alcatel in optical-network architectures
through hundreds of thousands of installations worldwide. That’s also where true reliability comes from.
