YesWare VBN transport systems
A YesWare VBN system can deliver service using EtherLoop modem pairs,
Ethernet switches, or a combination of both EtherLoop and Ethernet transport
systems. The following sections describe these YesWare VBN transport
systems.
EtherLoop-VBN
EtherLoop is an Ethernet-based modem technology that enables TCP/IP data
transmission simultaneously with voice service over the twisted-pair,
Category 3 (CAT 3) telephone lines of a local loop. EtherLoop technology
provides Ethernet-compatible service in locations out-of-range of standard
Ethernet LANs.
EtherLoop-VBN transport systems are ideal for data transmission in
environments such as hotel rooms that have no existing data network
infrastructure. EtherLoop delivers data transmission speeds comparable to
Ethernet at 5,000 feet and reliable service up to 21,000 feet. In addition to
guest room service, YesWare’s new Enhanced Modem Billing allows
EtherLoop modem pairs to serve any VBN service area, including conference
facilities and uncontrolled public areas.
Note: EtherLoop-VBN transport systems that use Enhanced Modem
Billing cannot be used simultaneously with Ethernet-VBN. See
“Combined EtherLoop/Ethernet VBN” on page 1-12 and “VBN billing
configurations” on page 1-17 for more information.
EtherLoop-VBN data transport method
Visitor computers connect physically to an EtherLoop-VBN transport system
as they would to a conventional Ethernet 10/100Base-T LAN, using an
Ethernet network interface card (NIC) and a Category 5 (CAT 5) cable
terminated with an RJ-45 connector. EtherLoop systems transmit TCP/IP data
and voiceband traffic using modem pairs configured in a point-to-point
architecture. EtherLoop modem pairs consist of a CPE (customer premise
equipment) modem and CO (central office) modem. Table 1-2 describes the
function of EtherLoop CPE and CO modems.

modem
The CPE modem transmits visitor data and voice to its designated CO modem over the
Category 3 (CAT 3) facility phone network. The CPE modem connects to the visitor
computer through an RJ-45 connection on the back of the modem. The CPE modem also
has two RJ-11 jacks on its backplane. One RJ-11 connects to a phone in the room, and the
second RJ-11 connects to the wall-jack of the facility phone network.
CO
modem
The CO modem controls the traffic flow from the CPE modem to the YWS ETH 1 interface.
The CO modem resides in an EtherLoop multiplexer shelf, typically located in the facility
equipment room. The CO modem connects to the YWS ETH 1 interface via an intermediate
Ethernet switch or hub. The CO modems must be on the same LAN segment as ETH 1.
