Product Summary
RAD's DXC-100 carrier-grade multiservice access node is a high-density, high-performance concentrator and digital cross-connect providing grooming, concentration and cross-connection for multiple E1/T1, E3/T3 and STM-1/OC-3 lines. Up to eight DXC-100 multiservice access node units can be stacked to provide a scalable, cost-effective central-site solution. DXC-100 satisfies a wide range of broadband and narrowband applications for carriers, cellular operators, ISPs, utility companies, and enterprises. Applications include E1/T1 or E3/T3 conversion, high-speed access to a carrier's backbone, grooming fractional traffic into full trunks, or aggregating Ethernet traffic from several locations into one channel. Possessing flexible interface capabilities, the DXC-100 supplies a simple method for connecting copper-based edge devices and networks to fibre-based cores, supplying a migration path to optical and packet-switched networks.
Benefits
• Reduces the number of leased lines • Scalable system provides a solution for any size network • Provides a migration path to optical and packet-switched networks • Redundant system and services modules and protection switching ensure dependable operation of the product • Central management solutions simply system organization, administration and management
Further Product Information
DXC-100 is a scalable multiservice access node that enables the incremental deployment of voice and data networks. As the networks grow, up to eight DXC-100 units can be stacked to provide very high density grooming, concentration and cross-connect.
Scalable platform with minimal initial investment
The modular, 6U-high DXC-100 is the newest member of the DXC family of multiservice access nodes. Each high-density chassis supports 80 n x 56/64 kbps, 88 E1, 88 T1, 11 E3, 11 T3, four STM-1, or four OC-3 links. Up to eight chassis can be stacked to support up to 640 n x 56/64 kbps, 688 E1, 688 T1, 80 E3, 80 T3, 32 STM-1, or eight OC-3 lines, for a powerful, central-site solution. (See the system capacity table below). The scalable platform enables a carrier to deploy a low-cost system that meets its current requirements and add more ports as its customer base grows.
Manages bandwidth for diverse voice and data applications
DXC-100 satisfies a wide range of broadband and narrowband applications for carriers, cellular operators, ISPs, utility companies, and enterprises. Applications include E1/T1 conversion, high-speed access to a carrier's backbone, grooming fractional trunks into full trunks, maximizing data traffic payload over E3, T3, STM-1 or OC-3 trunks, grooming data traffic from different locations into a channelized Ethernet router, and grooming monitoring signals for Quality of Service or advanced services. It optimizes the SS7 network by consolidating n x 56/64 kbps and E1/T1 functionality in a single, cost-effective, managed device. The DXC-100 can also aggregate Ethernet traffic from several remote sites via different trunks (for example, ISP or corporate traffic) into one stream by using the channelized router module. Operating as a digital cross-connect, the DXC-100 provides 4/3/1/0 non-blocking switching that is comparable to larger, more costly systems.
Migration path to optical and packet-switched networks
The DXC-100 can connect copper-based edge devices and networks to a fibre-based core, and performs port concentration and grooming for protocol-based platforms. Therefore, the DXC-100 provides a migration path to optical and packet-switched networks. The channelized router enables grooming traffic, saving the cost of additional equipment or ports.
Network management, system redundancy, remote configuration and diagnostics
Redundant system and services modules, together with protection switching, ensure dependable operation of the product. The RADview SNMP central network management system enables remote configuration and diagnostics, reducing operating expenses, eliminating costly technician visits, and maximizing network performance and uptime. The DXC-100 unit at the central site can use the in-band management feature to manage remote RAD multiservice access platform (MAP) products.
