Alcatel 1642 Edge Multiplexer — 155-to-622-Mbit/s Alcatel OMSN for customer premises & public/private companies

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 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

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 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.
