Ethernet is the undisputed, global choice for
Metro Access Networks (MANs) and Local
Access Networks (LANs). However, existing
copper access networks do not facilitate an
end-to-end high-bandwidth connection,
creating a bottleneck. This bottleneck is the
first mile of access. This refers to the access
link (most often a TDM-based copper circuit)
from the business customer’s office LAN
to their service provider’s MAN. ADTRAN
affords service providers the ability to remove
this bottleneck through the utilization of an
improved data transmission standard. This
standard, ITU-T G.998.2, is known as Ethernet
in the First Mile (EFM). ADTRAN EFM over
Copper (EoCu) defines a way to effectively
and universally bond together, lower band-
width copper loops or pairs of wires creating
a Carrier Ethernet access connection.
This innovative EoCu solution enables
service providers to extend packet-based
business-class services beyond the reach of
their fiber network by leveraging the existing
investment of copper-based TDM business
services assets. This means leveraging the full
advantages of TDM, the most understood,
successful, and ubiquitous business service
infrastructure. Due to budget restrictions and
time to market requirements, deploying fiber
to address uneven or disperse service demand
is not feasible, leaving a large percentage of
businesses to rely on copper business access.
The ADTRAN EoCu solution is comprised
of the NetVanta 800 family of NTU and can
be launched from our Total Access 3000
and Total Access 5000 platforms. The
NetVanta 830 Series NTU delivers enhanced
data rate capabilities to deliver up to 45 Mbps
of Ethernet service over bonded e.SHDSL.
The NetVanta 810 Series NTU leverages the
existing copper-based TDM business services
assets to rapidly extend Ethernet service to
any customer who currently uses DS1 or
E1 service. The NetVanta 873 can EFM bond
up to three DS3 connections to deliver up to
134 Mbps of Carrier Ethernet service.

Quality of Service Flexibility and Assurance
The NetVanta 800 Series deliver packet flow
capabilities certified compliant per the Metro
Ethernet Forum. These packet flow capa-
bilities offer the traffic classification and
bandwidth profiling capabilities required
to offer customers a flexible, tiered service
offer. In addition to this highly configurable,
granular bandwidth selection toolset enabling
Quality of Service (QoS) options, these same
network termination points support the
standards-based measurement and moni-
toring capabilities required to maintain a
carrier-grade Ethernet network. All of this
allows providers to create and meet
customer SLA agreements.
Reliable Service Connection Mechanisms
In the event a single loop fails, the NetVanta
800 offers resiliency, maintaining traffic
over the remaining active loops in order
to maintain service. Once the failed loop
is operational again, the NetVanta will auto-
matically detect its availability and return the
loop to the bonded group, providing the orig-
inal provisioned customer bandwidth. When
deployed through the Total Access 5000, these
NTUs tap into an unparalleled array of copper
loop diagnostic tools that afford an even
greater service assurance level.
Simplified Service Delivery
In order to improve service time to market
and reduce deployment costs, the NetVanta
800 Series delivers a feature set designed to
simplify service deployment and mainte-
nance. ADTRAN Total Access EMS employs
EZ-Ethernet Provisioning, minimizing the
number of steps to provision a new service.
The EIA-232 craft port enables local access
for configuration and status information.
A management VLAN is used to remotely
configure and collect status information.
The compact chassis and flexible deployment
options offer wallmount or rackmount for
superior flexibility. When wallmounted, any
NetVanta 800 only occupies a 17-inch by
10-inch area of the customer’s telephone
wiring closet. For rackmount installations,
custom 19-inch rackmount shelves
are available.
