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 space-
saving, next generation multiservice
building block for customer premises and
business locations. It enables business,
residential and mission-critical communi-
cations 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
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.

of today’s service providers, as well as the
expected need to provide telecom operators

The system may be configured as an STM-1 add drop
multiplexer (ADM) with a termination capacity of up to
by the Alcatel 1642 EM, even in multivendor networks.
Whether in telecommunications-office environments or
112 x 2 Mb drop for metropolitan networks or as an STM-4 at enterprise locations, the Alcatel 1642 EM has the right
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 on-
board 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 addi-
tion, service providers can also monitor subnets formed
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 end-
to-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 expe-
rience gathered by Alcatel in optical-network architectures
through hundreds of thousands of installations world-
wide. That’s also where true reliability comes from.
