New Nokia Synfonet Access Node Brings The Information Highway a Step Closer - Nokia builds up effective transport solutions
March 14, 1997
Nokia’s SDH product family, SYNFONET, provides the telecom operator with a total SDH concept for access and transport networks, incorporated under a full network management system, Nokia NMS. Nokia introduces today at the CeBIT fair in Hannover two new members to the SYNFONET product family; the SYNFONET Access Node (SAN) and SYNFONET STM-16 Node.
Optimising operator investment
The SYNFONET Access Node (SAN) is a genuine STM-1 SDH node and therefore provides the same benefits applicable to the entire SYNFONET product range. With SAN the telecommunications operator can be assured of “building as they go”. The flexibility of the concept enables the operator to change networks as and when needed according to business demands. This is especially important in competitive environments where mesh networks are starting to replace inflexible tree and ring topologies. Thus the SYNFONET Access Node fits into today's modern and demanding networks and guarantees a growthpath in rapidly changing business environments.
In case of fibre cut or node break, it is essential to provide automatic synchronisation and management connection protection. This can be done with the Nokia SYNFONET solution. The Nokia SDH network has "three networks in one": transmission, synchronisation and management ensuring a high quality network at all times.
SAN is especially developed for solutions where compactness and high functionality are particularly important. Such application areas are e.g. base station connections and last fibre mile connections in urban or residential environment. SAN is also beneficial for direct business customer access with managed line services up to the customer’s premises for leased lines, PABXs, LAN and ATM interconnections, amongst others.
Ultimate compactness
The SYNFONET Access Node is configurable as TM (Terminal Multiplexer) or ADM (Add/Drop Multiplexer), has all the basic SDH features mounted on one core plug-in unit that can also have 8 x 2Mbit/s interfaces. The operation mode of the node is defined by selecting the optical interface plug-in module that is needed for the application. . When more tributary interfaces are needed they can easily be added next from the core unit.
Versatile operation environment
SAN can be installed in a various sizes of cartridges suitable for rack and cabinet installations. When the node is located in customer premises a specially designed unobtrusive case, the Wall Box, is the best choice. The system architecture of the SAN is highly flexible: the configuration can easily be modified to respond to the challenges set by the operator’s rapidly changing business environment.
Note to the editors:
The access network: Optimising access networks - i.e. lowering maintenance costs and improving return on investment - is a critical factor. The access network takes the major part of operators' investments in the total transmission network. In deregulated market environments, competition between operators is increasing which in turn forces them to intensify their focus on their core customer segments in order to secure profitable business. This in turn sets demands for high quality and secure service provisioning for end users.
SDH: SDH equipment improves the capacity and availability in a telecommunications network. It enables the operator to, for example supervise and allocate network resources for optimal performance at any time. SDH is also a platform for future telecommunication services. The Nokia SYNFONET family consists of STM-1/4, STM-16 and SAN (SYNFONET Access Node) products.
Nokia has delivered SDH systems to more than 50 customers in over 20 countries.
