In particular, the head office required heavy-duty equipment to manage the network, and the scalability of the Nortel Networks routers, coupled with the processing capacity, won the day. This architecture is a unique feature of Nortel Networks products. When the internal bureau merged with SDS, the latter took over the operation and maintenance of this post office network. Although SDS had previous experience with networking products from other vendors, the bureau chose to enhance the network and base its solutions to customers primarily on Nortel Networks equipment. This provides hardware redundancy options, fully distributed system software, and full fault-management capabilities.
Similar deployment is replicated throughout other regions of Norway.
The BayStack AN provides WAN connectivity to ensure network availability for remote connections while minimizing network operating costs. The SDS network also uses Nortel Networks System 5000 switching hub to concentrate the Post Offices' connectivity and Internet traffic over the dial access network. The System 5000 provides a structured wiring concentration point, and assigns network resources to LAN segments via network management application software. These servers concentrate SDS's mixed ISDN and analog traffic by combining a digital modem and remote access service into a single compact chassis. Approximately 200 routers with Nortel Networks router software enable managed services, and 50 routers provide telecommuting services.
