Patton?s Model 3324 VDSL Access Concentrator provides a simple and efficient method of delivering voice and high speed data services over existing copper infrastructure. The Model 3324 employs VDSL (very high bit-rate DSL), the fastest digital subscriber line technology. This technology enables carriers and service providers to provide broadband services that previously could not be provided using other forms of DSL. Using a Model 3324 VDSL Access Concentrator with Model 1068 CPEs will provide services for up to 24 users.

The Model 3324 is a fully manageable Layer 2/3 switch with 24 independently configurable VDSL ports. This feature allows service providers to differentiate their high speed data services. The Model 3324 comes standard with two auto sensing RJ-45 100/1000BaseT Ethernet ports or a optional industry standard GBIC (Gig Fiber) uplinks.

The Model 3324DV?s unique 1U chassis design includes on-board POTS/IDSN splitters for all 24 VDSL channels. This feature enables the simultaneous use of voice and data over a single 2-wire twisted pair without the additional cost and space of an external splitter panel.

For larger applications, up to four Model 3324s can be cascaded to provide a scalable VDSL solution (96 ports). The Model 3324 24-Port VDSL Access Concentrator is Patton Electronic?s flagship product and is compatible with the Patton 1068 VDSL CP units.

Voice and data services over VDSL
Using Patton?s VDSL Access Concentrator at a central location, up to 24 full-service links can be routed to various room locations. The CO or ISP would provide the fiber uplink from the network to the Model 3324 location. The POTS lines delivered from the PSTN would be concentrated and delivered to the Model 3324 on an RJ-21 connector. The 3324 combines the POTS and Ethernet signals and sends them over the VDSL links to the individual rooms over existing twisted pair, voice-grade wiring. A 1068CP standalone unit is placed in each room to split the signals back into Ethernet (data) and POTS/ISDN (voice) forms for delivery to the end-user. The Model 3324 allows VDSL services on each channel to be configured at various symmetric and asymmetrical line rates to differentiate services or to increase the distance capabilities.
