Affordable Scalability to Hundreds of T1/E1 Ports

DNX-88 Multiservice Cross-Connect

Introduction

The DNX-88 offers an economical approach to transmission network build-out. For a minimal front-end investment in common equipment, a network operator can rapidly provision services on a right-sized platform, and leverage that investment later by scaling the DNX-88 up to S-DNX levels to accommodate growth.

The exceptional density and proven reliability of the DNX-88 enables network operators to push core network functionality closer to the network edge. This intelligent approach to bandwidth management reduces cost and extends the life of core resources by providing port consolidation and backhaul facility concentration. With the addition of a CPX Module Set, the DNX-88 consolidates circuit/packet processing within a single platform, enabling cost-effective, carrier-grade migration from TDM to IP.

Product Highlights

Excellent Midrange DCS Scalability – scales to over 600 T1s, 500 E1s, 24 fully loaded DS3s or STS-1s, 30 E3s or up to 8 fully loaded OC-3/STM-1 interfaces.

Non-Blocking 3-1-0 Switching – utilizes a high-speed cross-connect switching fabric, including full granularity to DS0 levels.

Optional CPX Module Set – industry-first integration of circuit/packet functions on a carrier-grade cross-connect supports a seamless transition from TDM to IP technology in fixed line and mobile networks.

Application Flexibility – leverages all narrowband and broadband interfaces in the DNX portfolio, including T1/E1, T1/E1 APS, T3/E3, STS-1, and OC-3/STM-1, while retaining the ability to groom multiservice traffic by performing non-blocking 3-1-0 cross connections.

Resiliency – offers several layers of protection for designing resiliency and availability into DNX-88 based transport networks. Capabilities include redundant control, switching, and power circuitry, device-level protection, Automatic Protection Switching (APS) for facility link protection, automatic re-routing of traffic to alternate paths in the event of primary path failures (path protection), and even site protection (disaster recovery) options.

System Management – benefits from the advanced capabilities of the ENvision Plus NMS. ENvision Plus works with the DNX-88 to simplify connection provisioning, improve network resiliency via automated path protection and site protection, streamline event and alarm management processes, and provide visual test access and line diagnostics. Other capabilities include multi-level topology views and bandwidth reporting utilities for low-level management of the switch fabric.
