The Evolution of Digital Loop Carriers
Overview
Since 1979 when the first DLC was introduced to cost-effectively deploy
voice service in rural areas, the Digital Loop Carrier (DLC) has become the most efficient method for providing voice service to subscribers. DLCs
have grown in size from 96-line channel bank type terminals to large 2048-line terminals with fiber optics and built in network management. Switch interfaces have evolved from the original analog interfaces to GR-303
to OC-3c SONET.
And, the evolution continues. DLC vendors tout Next Generation DLCs that promise to deliver broadband service as easily as voice. These solutions may work in the short run; however, they cannot scale to handle high user take rates and much higher usage per subscriber. Additionally, these solutions continue to perpetuate a circuit-switched architecture that is ill suited to deliver broadband data effectively.
Occam Networks has developed the next logical evolution of the Digital Loop Carrier – the Broadband Loop Carrier, a new class of local loop
platform that dramatically simplifies delivery of broadband and voice
services from the local distribution network.
