Applications Frame Relay Access and Concentration Server
2.8 Frame Relay Access and Concentration Server
This section highlights the capabilities of the integrated access system Frame Relay server
card as a cost-effective, efficient, and intelligent high-speed Frame Relay Assembly and
Disassembly (FRAD) device and access concentrator in a Frame Relay network. This enables
the service provider to deliver Frame Relay and Internet services with a high degree of quality
in an economical fashion.
The following is a list of the Frame Relay server card key benefits:
•
Highly efficient assembly, disassembly and concentration of Frame Relay traffic allows
for significant Frame Relay switch port savings.
•
High Frame Relay port density offers significant hardware savings when compared to
typical backbone switches making it suitable for deployment at the customer premises.
Bringing the frame relay network features closer to the end-user and CO reduces
backhaul charges due to efficient use of the frame relay backbone switch port.
•
100% compliance with industry Frame Relay standards enables ready interoperability in
multi-vendor networks.
•
Support for existing UNI (User to Network Interface) and NNI (Network to Network
Interface) standards implies that the frame relay server easily integrates into existing,
standards-compliant frame relay infrastructure of the service provider.
•
Manageability via SNMP and TELNET eliminates need for separate network
management package and offers comprehensive diagnostics for both physical and logical
network.
•
Complete Support for physical layer diagnostics. In addition, it provides network access
for a wide range of devices ranging from high-speed data interfaces (HSU), DDS
interfaces (OCU-DP, DS0-DP), IDSL interfaces (BRI), and sub-rate data (FRAD).
•
Comprehensive, standards-based congestion management techniques.
•
Standards based congestion management ensure interoperability with existing
infrastructure and enables the service provider to offer better, more cost-effective Frame
Relay services to its subscribers.
The Frame Relay Server can be deployed in the following application scenarios to provide a
very cost-efficient and high-quality Frame Relay access to the end-users:
•
Frame relay switch port savings
•
Frame relay and Internet service provisioning
•
IDSL service provisioning
•
Grooming and concentration in cellular networks
•
Central Office FRAD
•
Frame relay concentration at hub sites
