Networks
The emergence of today's new Broadband
technologies such as EFM, ADSL2/2+, and PON
allows service providers to pursue additional
revenues by offering services that require high
bandwidth connectivity. In evidence of this trend,
total DSL ports rose 9% in 4Q04, following an 11%
increase in 3Q04, with a revenue surge of 14% to
$1.4 billion (Infonetics Research, Feb. 2005). Further
predictions hold that fiber-deep communication
networks could reach nearly half of all U.S. homes
by 2010 (The Communications Media Analysis Group, Dec, 2004).
Service providers are investing heavily in installing
fiber-to-the-premise in order to meet current and
predicted demand for high bandwidths in the last
mile for revenue-generating services, such as
delivery and distribution of voice, high-speed data,
and high-definition video services - commonly
known as "triple play" - over a single channel .
To compete sucessfully for customer business
while building future-proof topologies, service
providers must outpace competitive threats,
increase revenues, and reduce churn. The most
cost-effective solutions take advantage of existing
infrastructure, minimize up-front investment, and
plan for future fiber deployments that do not
require "forklift" upgrades in equipment.
A key requirement is a strategy for efficient, secure
management of your fiber access network, end-to-
end, in order to reliably deliver high quality voice,
video and data services to a growing pool of
customers.

GDC's SpectraComm Ethernet switch with fiber uplink provides out-of-band
management that is diverse-routed to preserve triple-play bandwidth to
customers, and maintain security for"in demand" applications.
Page 2Out-of-Band Management Strategy for Fiber Networks
Bandwidth-hungry triple play applications need to be supported by a network architecture and a management infrastructure that will avoid bottlenecks or outages. Strict inband management means a loss of fiber uplink will interrupt customer traffic and the management path. To avoid this single point of failure, fiber access networks must include both inband and out-of-band management topologies. This provides an alternate management path and protects and maintains service delivery to customers, with minimum to no interruptions.
Extending management across the fiber network may expose valuable network resources and data to cybercrimes such as computer intrusion, denial-of-service attacks, data sabotage or theft, and identity or service theft. Components deployed throughout the provider's network need built-in comprehensive protection to minimize these risks while allowing easy access for authorized personnel.
Inband or OB ManagementAs customer take-rates increase for fiber services, those services become critical to their everyday lives. With no out-of-band management solution, the network manager may not be unaware of fiber uplink failures until alerted by customers. Loss of fiber uplink is a key factor that drives churn, which can, according to industry analysts, be as high as 3.5% per month. Fiber access networks need redundant management strategies that make 24/7/365 availability the top priority, limit exposure to outages, and minimize downtime in the event of loss of fiber uplink.
Every dollar spent on infrastructure for new fiber deployments must show significant ROI. Systems must be adaptable, scalable to changing network architectures, and compliant with stringent NEBS standards that protect the integrity of critical carrier and enterprise environments.

The Best Connections in the Business
Product Overview General DataComm designs and manufactures the SpectraComm family of access blades, including the SC-ES Ethernet Switch. An SC-ES/FTTX solution provides a fully managed switching platform for OBM vigilance that reduces lost profits from customer down time �and helps to eliminate costs associated with truckrolls to edge equipment locations.
Security Features SC-ES/FTTX supports TACACS+ Authentication for network equipment access, provides "safe from anywhere" configuration and statistics access, auto-learns legal MAC addresses, and enforces MAC address filtering with alarm notification for port-by-port access control.
