Overview

Arrive Technologies specializes in high capacity devices that enable the transition between the existing legacy PDH and SONET/SDH networks and the emerging Etherent/MPLS/IP based networks. PDH and SONET/SDH will remain as the backbone of the layer one transport for many years due to the 10's of millions of circuits now installed. Over time, other Ethernet layer one technologies will begin deployment and for many years the network will be a mix of PDH, SONET/SDH and Ethernet at layer one. In order to allow carriers to offer layer 2 and above based services on any installed layer one transport, Arrive is developing a family of MSADMs, Mappers, Multi-protocol Processors and Carrier Ethernet interworking devices such as high capacity Circuit Emulation Engines and Ethernet Packet Flow and Traffic Management Engines. These devices when combined in various ways will permit almost any service to be carried over any layer one transport seamlessly and transparent to the end user. The first seven devices intended to satisfy this network transition strategy are briefly described below.
