Verizon to Launch SHDSL

Verizon plans to begin offering symmetric high bit-rate DSL (SHDSL) featuring variable bit rate, non -real time (VBRnrt) quality of service (QoS). The service will support symmetric rates up to 1.5 Mbps. Verizon's VBRnrt arrangement supports bursty data traffic with average and peak traffic parameters and allows SHDSL traffic to take precedence over unspecified bit rate (UBR) traffic in the network. Regular DSL traffic in the Verizon network is UBR. Verizon has already conducted successful SHDSL trials in Maryland and Florida. Verizon plans to offer SHDSL nationwide within the serving areas of its current footprint. SHDSL will be marketed to small and medium sized businesses, branch offices of large enterprise businesses, and as a wholesale service for other ISPs.
