A metropolitan network that supports a wide range of service capabilities allows service providers
to offer a tariff mix to meet each customer’s needs. The Cisco ONS 15454 provides the foundation
for building an advanced multiservice network over an extremely reliable SONET/SDH
infrastructure (Figure 3). The Cisco ONS 15454 with CE-Series cards facilitates the delivery of
data services such as transparent LAN services (TLS) or Internet access over a carrier-class
optical infrastructure supporting traditional TDM services. The Cisco CE-MR card, with VCAT and
LCAS functions, helps service providers offer a wide variety of Ethernet service-level agreements
(SLAs). Virtual concatenation (VCAT) provides a more efficient use of the transport bandwidth for
data user interfaces, and link capacity adjustment scheme (LCAS) provides an effective way for a
service provider to change the allocated bandwidth to each customer. Additionally, provisioning an
Ethernet circuit over a network equipped with a Cisco CE-MR card is easily accomplished through
the use of the Cisco ONS 15454’s embedded A-to-Z circuit provisioning wizard. The Cisco CE-MR
card also supports TL1-based provisioning to simplify integration with many embedded service
provider management systems.
