6Visitor and Community Network Access Concentrator Installation Guide

System Overview	The Visitor and Community Network provides fast Internet connectivity
	and fast corporate access to end-users of up to 10 Mbps full duplex, over
	an existing cabling infrastructure and supports all Plain Old Telephone
	Services (POTS).
	The Visitor and Community Network System serves the following
	applications:
	■ Multiple Dwelling Units (MDU)
	■ MDUs include apartment houses and hotels.
	The customers that benefit include tenants and hotel guests who
	receive Internet services and use e-mail over much more
	convenient connections than currently possible. Business travelers
	can access corporate intranets at faster speeds. IT service providers
	and hotel operators can expand end-user services (video, virtual
	gaming, etc.) in conjunction with billing services without forfeiting
	POTS revenues. NSPs and ISPs benefit by expanding service
	boundaries to E-commerce and local network applications.
	■ Multiple Tenant Units (MTU)
	■ MTUs comprise mainly office complexes.
	In MTU application existing LAN infrastructure can be extended to
	4 kilo feet to locations currently lacking LAN cabling through the
	Visitor and Community Network system.
VCN Access	The function of the VCN AC is to combine data and analog voice in the
Concentrator	direction of the VCN APs (VCN Access Point) and to split voice and data in
Functionality	the direction from the VCN APs. Analog voice (telephone) is routed to the
	analog PBX. Data is transferred to the Ethernet Switch. The VCN AC
	allows simultaneous transfer of voice and data, up to 10 Mbps, on each
	telephone extension line.
	The VCN AC works with the SuperStack II Switch 1100 and 3300.
