1.4.2 MTU Application
The following figure depicts a typical application of the IES-2500 in a large residential building, or multiple tenant
unit (MTU), that leverages the existing phone line wiring to provide Internet access to subscribers in the building.
A subscriber connects a computer to the phone line in a unit using an ADSL modem. The other end of the phone
line is connected to a port on the IES-2500. The IES-2500 aggregates the traffic from subscribers and then forwards
it through an Ethernet connection to the Internet.
