Citynet Picks White Rock

RICHARDSON, Texas -- White Rock Networks, a leading provider of next-generation optical transport systems for metro networks, today announced that Citynet, a facilities-based provider serving retail and wholesale customers in the Mid-Atlantic and Midwest, has selected its VLX300 Service Edge Concentrator for cost-effective aggregation of T1- based IP services near the network’s edge.

The VLX300 provides up to 12 channelized DS3 interfaces for aggregation of T1-based IP business services, typically delivered with PPP, MLPPP, HDLC, or Frame Relay to enterprise routers at the customer premises. It also provides two options for the backhaul of consolidated IP traffic: clear channel DS3, which utilizes Frame Relay virtual connections for customer segregation, and GbE which utilizes VLAN tagging to segregate customer traffic.

Leased DS3 facility (Off-net) cost savings are realized by a significant reduction in DS3s through the elimination of partially filled circuits and statistical multiplexing. Central Office or POP aggregation (On-net) savings are also derived through router port cost reduction when a consolidated and efficiently packed GbE interface is provided to the router in place of channelized DS3s.

“As we roll out new wire centers, aggregating voice and data as close to the customer as possible is critical for conserving network resources and providing good service levels,” said Eric Krichbaum, Director of Retail Engineering for Citynet. “The VLX300 fits that process well by being completely transparent to the end user, while still giving us the aggregation we were looking to achieve.”
