IP DSLAM
Our IPDSLAM is a carrier class DSL access solution tailored to meet customer requirements for high-speed remote access and subscriber aggregation. The IP DSLAM directly and costeffectively interfaces with the evolving IP network in order to deliver high capacity traffic aggregation and robust, “always on” services. In an increasingly competitive environment, the IP DSLAM affords simple and reliable delivery of high demand applications.

 

UNITED COMMUNICATIONS IP DSLAM
 

PRODUCT TECHNICAL DESCRIPTION

The IPDSLAM terminates ATM cells from existing, compatible customer premise equipment and converts them into IP traffic. By directly connecting to an IP router or switch, the IP DSLAM eliminates the bandwidth overhead and provisioning complexities associated with traditional ATM DSLAMs. Decreased dependence on ATM results in the elimination of additional ATM-related elements including Broadband Remote Access Servers (BRAS), greater throughput and simplified management. By utilizing IP instead of ATM in the core, carriers realize significant operational and capital savings. Comprehensive management and operation support is delivered
via United Communications' SNMP-based Network Management Software (NMS).

Network Management Software (NMS) is a centralized, client-server based network management diagnostics tool that supports batch configuration mechanisms, which can significantly simplify the provisioning task and minimize provisioning errors. Traffic from multiple IPDSLAM can be aggregated and passed on to BRAS for layer 3 functionality.
