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 fiber-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 inband management feature to manage remote RAD multiservice access platform (MAP) products.
