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 bandwidth
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 capa-
bilities 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 capabilities
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 selec-
tion toolset enabling Quality of Service (QoS)
options, these same network termination points
support the standards-based measurement and
monitoring 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 main-
tain service. Once the failed loop is operational
again, the NetVanta will automatically detect its
availability and return the loop to the bonded
group, providing the original 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 maintenance.
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.
