OVERVIEW
The EtherXtend devices are next-generation Ethernet-enabled customer
premises equipment (CPE). EtherXtend provides 4-port and 8-port models
that perform the functions of a network extender by lengthening the reach of
Ethernet packets. EtherXtend allows Ethernet packets to pass over existing
copper wires that link the service provider (a central office, street cabinet,
pole, or tower) to a subscriber’s CPE. This distance is known as Ethernet in
the First Mile (EFM). EFM is a set of specifications that allow users to run
Ethernet protocols over previously unsupported media such as single pairs of
copper wires in subscriber access networks. EtherXtend EFM is covered by
IEEE standard 802.3ah.

Product models
Table 1 provides the model numbers for the EtherXtend products.
Product description
The 4- and 8-port EttherXtend SHDSL Ethernet access devices
(ETHX-SHDSL-4 and ETHX-SHDSL-8) deliver bonded high-speed EFM
services over SHDSL. The ETHX-SHDSL-x device family provides 802.3ah
compliant SHDSL bonding with advanced features, including Zhone’s
Multimedia Traffic Management (MTM). In addition, full compliance to
802.3ah industry standards provide high reliability, low latency, and
integrated operation, administration, and maintenance (OAM) features for
advanced management of Ethernet lines.

With Zhone’s proprietary lightweight Ethernet bonding technologies,
EtherXtend provides dual-mode operations to allow EtherXtend to aggregate
into standards-based products such as the MALC broadband loop carrier, and
other EtherXtend-SHDSL-x units. EtherXtend can also connect into
pre-standard Ethernet loop bonding products such as Zhone’s Ethernet access
products.
Technology description
EFM provides high performance for data traveling across a connection
between the subscriber and the service provider. This connection has been a
stopgap for Internet traffic, limiting performance to whatever the constraints
of this connection are. Regardless of how fast data could travel over xDSL
network links, the data usually would be slowed down on the last link
connecting the subscriber to the service provider.
The EtherXtend provides an ideal solution for the following scenarios:
•LAN extensions in metro areas
•a cellular site backhaul

•any point-to-point application requiring Ethernet connectivity over the
WAN
The EtherXtend can be used to create a point-to-point connection over a dry
copper pair. Within a campus environment or multi-tenant unit (for example, a
hospital) where the subscriber owns the cabling infrastructure, copper pairs
are often available throughout the facility as unused telephone cabling.
Any cell site running EvDO CDMA or 3G provides an Ethernet interface for
mobile applications such as mini-web browsing. Typically, these Ethernet
ports are connected to a T1 router so they can be carried over long distances to
the CO where they are terminated into Ethernet.
The EtherXtend platforms not only provide a more cost-effective alternative
to deploying dedicated T1 router equipment at each cellular tower, but they
also provide loop bonding capabilities to reach the higher bandwidth demands
of EvDO and 3G.
The Ethernet port of the cell tower simply connects to the appropriate
EtherXtend platform, and the Ethernet frames are transported directly to four
SHDSL lines. At the CO, the extended LAN connection presents a single
Ethernet RJ-45 interface for simple connectivity to the data network.
Loop bonding allows multiple physical lines to be grouped together to achieve
higher data rates. For example, four 5.7 Mbps SHDSL lines can be combined
to provide up to 20 Mbps of bandwidth. Loop bonding is an easy way to
increase line speeds where extra copper is available.
Zhone’s EtherXtend technology uses existing copper facilities to deliver high
bandwidth Ethernet services over existing copper loops to business
customers. Products from this technology are both EFM standards compliant
and compatible with existing bonded copper solutions to deliver
point-to-point Ethernet connectivity over the WAN.
EtherXtend transports Ethernet directly over SHDSL, T1, or E1. This makes it
easy to interconnect LANs over virtually any distance. These transparent
LAN services allow businesses with broadly distributed remote offices to
operate as if located on the same local network.
EFM media
Copper wire access lines are the dominant access media today. While optical
fiber facilities appear to be gaining market share, the existing media (copper)
still is more dominant in terms of volume of footage, number of entry points,
and number of regions governed by a technology type.
EFM over copper services offers more than fiber class speed. They support a
wide range of applications and opportunities. EFM technology provides
benefits for installations provisioning high-speed, high-value services and for
users of those services who realize cost and performance improvements
delivered rapidly and flexibly.
EFM over copper applications include:

Ethernet services
EtherXtend User’s Guide 15
•Frame Relay migration to E-LAN services
•T1/E1 replacement with E-Line services, including internet access,
wireless backhaul, voice access, and wholesale services.
•Transparent LAN service (TLS)
EFM over copper technology supports a wide range of voice, data, and video
services and applications. Many applications are extensions of those now
supported by T1/E1 and Frame Relay services. However, they are more
responsive to new demands by customers by providing much higher data
rates.
Ethernet services
The Metro Ethernet Forum (MEF) has helped to define standards for Ethernet
services. These standards helped to establish the user network interface and
Ethernet virtual connection for two principal services: E-Line and E-LAN.
E-Line services include point-to-point Ethernet connections using Layer 2
VLAN infrastructure with two types of user network interface (UNI) access:
802.1Q-in-802.1Q (QinQ) and dot1Q encapsulation. These services are also
known as Ethernet Relay Service (ERS) and Ethernet Wire Service (EWS).
E-LAN services provide multipoint-to-multipoint services using virtual
private LAN services (VPLS) or simply layer 2 VLAN core.
Carrier Ethernet has developed a series of extensions to standard Ethernet that
provide improved performance on the Internet.

Do not block system air vents; this will deprive the system of the airflow
required for proper cooling. Sufficient clearance must exist on all sides of the
rack to permit equipment access. Connect the system to the power supply
circuit as described in this document. Do not overload the system or power
supply circuit. Ensure that proper system grounding is performed and
maintained.
Important safety instructions
Read and follow all warning notices and instructions
marked on the product or included in the manual.
1Slots and openings in the product are provided for ventilation. To ensure
reliable operation of the product and to protect it from overheating, these
slots and openings must not be blocked or covered.
2Do not allow anything to rest on the power cord and do not locate the
product where persons will walk on the power cord.
3Do not attempt to service this product yourself, as opening or removing
covers may expose you to hazardous voltage or to other risks. Refer all
servicing to qualified service personnel.
4General purpose cables are used with this product for connection to the
network. Special cables, which may be required by the regulatory
inspection authority for the installation site, are the responsibility of the

6A rare phenomenon can create a voltage potential between the earth
grounds of two or more buildings. If products installed in separate
buildings are interconnected, the voltage potential may cause a hazardous
condition. Consult a qualified electrical consultant to determine whether
or not this phenomenon exists and, if necessary, implement corrective
action prior to interconnecting the products.
