Introduction
As the demand for fixed wireless services expands, today’s network operators must deploy, scale, and manage a wide range of radio networks cost-effectively and efficiently. Fixed radio resources offer solutions that can reduce current operation costs more quickly than alternative strategies, such as leased facility or competitive providers, yet are restricted by line of sight issues.
Sycamore DNX Multiservice Cross-Connects complement these solutions. DNX platforms offer fixed radio network operators a choice of transmission and management interfaces in right-sized packages for any application. Installing DNX products in conjunction with single or multiple radios provides operators with a solution for interchanging and optimizing bandwidth, while greatly simplifying the provisioning process.
DNX solutions provide both electrical and optical interfaces, in speeds ranging from OC-3/STM-1, T3/E3/STS-1, and T1/E1 to Ethernet, Nx56/64 Kbps, and sub-rate data. A non-blocking switch fabric optimizes the air interface bandwidth by switching traffic at the time slot or T1/E1 levels. This solution ensures complete utilization, regardless of the interface provided by the radio, while appearing transparent to other network elements.
Point-to-Point
Point-to-Point Configurations
When using a fixed wireless solution to deliver bandwidth between two locations, the DNX can be deployed as an access concentrator. Whatever the bandwidth requirements, the DNX ensures efficient use of microwave resources. These applications are often deployed in conjunction with terrestrial services, when network availability is of the utmost priority. The T1/E1 APS options on DNX platforms provide a disaster recovery mechanism to ensure reliable service wherever a failure occurs.
Point-to-Multipoint Configurations
In an application that requires the operator to multipoint or hub radio gear, perhaps at a high elevation, the DNX can scale sufficiently while offering the right-sized solution for end point locations. By positioning a DNX-11 or DNX-88 at the hub location, traffic can be aggregated and/or switched from the inbound radios further north in the network, or hair-pinned to another end point location. A wide selection of transmission interfaces and extensive diagnostics ensure operators can use the DNX to maximize radio investments while reducing operating expenses.
Point-to-Multipoint
Ring and Virtual Ring Configurations
DNX products add value, whether the network utilizes ring-based radio equipment or back-to-back radios configured at each node along a virtual ring. In the small bandwidth applications found in mobile operator networks, multiple radios are typically configured to drop the desired bandwidth at one location while inserting the remaining bandwidth on another radio destined for the next location. These configurations are normally hard-wired and offer no disaster rerouting. DNX platforms with APS functionality provide optical network resiliency and simplify provisioning.
Ring and Virtual Ring Configurations
Building Mesh-Based Networks (Protocol Independent)
When the network topology calls for a fully meshed configuration, the DNX solution simplifies network operations while increasing network availability. Utilizing Sycamore’s ENvision Plus network management system, the DNX family performs as part of an orchestrated network, with end-to-end, point-and-click provisioning and circuit rerouting should transmission facilities fail. These features bring value to fixed wireless networks and networks that are a mix of wireless and terrestrial facilities.
Mesh-Based Configuration
Proven Reliability
With DNX platforms installed in a fixed radio location, virtually every remote device can be managed from a centralized location. By creating an IP-based telemetry channel within the radio payload facilities, the DNX delivers visibility to elements of the network that were previously unmanaged. This contributes to OpEx savings by enabling the radio’s telemetry resource to be networked within the same IP-based channel. Extensive integral diagnostics enable swift resolution of service-affecting issues from central locations, reducing the need to dispatch technical personnel while increasing network availability.
Intelligent Network Management
ENvision Plus ties the solution together by providing traditional node management functions and acting as a network management resource for all DNX equipment deployed, regardless of the transmission facilities used to interconnect the devices. ENvision Plus enables provisioning through a point-and-click interface at the source and destination end points, automating the process of making intermediary connections, and automating disaster recovery. While each connection can have multiple paths to its end points, ENvision Plus is aware of the network topology and rearranges bandwidth resources on a priority basis.
