THE CISCO ADVANTAGE

The Cisco ONS 15454 MSPP solution offers significant advantages over traditional optical network elements combined with external

Layer 2 and Layer 3 devices. These advantages are summarized as follows.

Integrated Multiservice Capabilities

The Cisco ONS 15454 MSPP solution supports traditional TDM-based, private-line services (for example, DS-1/E-1, DS-3/E-3, and OC-

n/STM-n) along with advanced Ethernet-based services, simplifying service provider migration to new data tariffs and interface flexibility

for enterprise users.

Flexible Architectures

The Cisco ONS 15454 platform supports two- or four-fiber bidirectional line switched ring (BLSR) or multiplex section-shared protection

ring (MS-SPR), unidirectional path switched ring (UPSR) or multiplex section protection (MSP), linear automatic protection switching

(APS) or subnetwork connection (SNC), and path-protected mesh networking (PPMN) architectures. The Cisco ML-Series services cards

can be deployed over any of these architectures and protection schemes, allowing the service provider to build a network that meets the

customer’s SLA requirements. The platform facilitates in-service optical bandwidth expansion using card upgrades, allowing customers to

expand their networks to match demand without major replacement, and allowing network expenditures to better match revenue and

bandwidth requirements.

Efficient Network Management

Management is simplified through a common DCN network connection and user access for Ethernet and optical functions.

Unified Software Load

One software load supports transport and data capabilities, eliminating unnecessary guesswork from ordering, installation, and upgrades.
