Grand River Mutual Telephone, the largest telephone co-operative in Missouri, will deploy Turin Networks’ flagship Traverse Platform in a new RUS-financed OC-192 SONET network spanning its exchanges in northern Missouri and southern Iowa. Turin’s Traverse platform integrates SONET Add-Drop Multiplexer (ADM), digital cross connect (DCS) and edge switch functionality in a single compact system that scales from DS1 to OC-192 per system slot. In addition to SONET transport, Grand River is using the Turin equipment to aggregate traffic from Ethernet-based DSLAMs, as well as to deliver TDM DS1 and DS3 private-line services to their customers. The new OC-192 system could also be used to deliver services such as video transport and bandwidth wholesaling in the future. Grand River’s network, which includes 33 exchanges in Missouri and 15 exchanges in Iowa, serves in excess of 25,000 access lines. Financial terms were not disclosed.

- Turin’s Traverse platform is based on a custom, distributed ASIC switch-fabric that grooms and switches both TDM and packet traffic. It supports the full SONET feature set, including UPSR, BLSR and 1+1 APS. It also incorporates a unified optical control plane and advanced bandwidth management system, including virtual concatenation and rate shaping features, as well as capabilities that enable the fast activation and delivery of dynamically scalable Ethernet services.
In May 2003, Turin added scalable wideband DCS functionality to its flagship Traverse Platform. The new integration of wideband cross-connect functionality further reduces the number of elements needed in the network. Turin said its Traverse Platform supports seamless growth from 96 to 384 STS-1 equivalents (2688 to 10,752 VTs) of fully protected, non-blocking capacity in a single shelf that takes up one fourth of a standard 7-foot rack. Expansion can be accomplished completely in-service, in 48 STS-1 increments.
