Compact Design for Limited Space
All of the VDSL-Ethernet switches in the VES-1000 Series have built-in voice-signal splitters. This means that
service providers do not need to allocate extra space for external splitters.
Scalable Platform for Future Expansion
The flexible design of the VES-1000 Series allows service providers to start with minimum cost. As the number of
users and applications increases, additional switches from the VES-1000 Series can be added to provide greater
bandwidth.
1.3 Applications
The VES-1008A has 8 available VDSL ports as well as a combined USER/CO Telco connector. Expanding on this
flexibility, the VES-1012 features 12 VDSL ports as well as separate CO and USER Telco-50 connectors. The
applications and operating environment (and associated diagrams) presented in this chapter primarily focus on the
VES-1012; however they are equally applicable for the VES-1008A.
The following are typical VDSL applications for the VES-1000 Series of switches:
1. Multiple Tenant Unit (MTU)
2. Enterprise
3. Campus.
1.3.1 MTU Application
The following figure depicts a typical application for a VDSL-Ethernet Switch in a large residential building, or
Multiple Tenant Unit (MTU), that leverages existing phone line wiring to provide Internet access to all tenants.
A tenant connects a computer to the phone line in a unit using a VDSL modem. The other end of the phone line is
connected to a port on a VES-1000 Series switch. The VES-1000 Series switch aggregates the traffic from the
tenants to the Ethernet port and forwards it to a router or switch. The router (or switch) then routes the traffic
further to the Internet.
