Introduction
The Octal High Speed Data (OHSD) Module supports a diverse mix of data applications that address the evolving needs of competitive network service providers, emerging wireless carriers, and corporate enterprises.
The DNX-resident OHSD Module consists of a front application module and rear interface module that provide individual connectivity for industry standard data interfaces operating between 9.6 Kbps and 2.048 Mbps. A number of optional cable assemblies are available to facilitate customer installations.
Capabilities and Features
Data applications are typically not the forte of traditional digital cross-connect systems (DCS), particularly at higher speeds. In contrast, an Integrated Access Device (IAD) often provides a strong complement of high-speed data options. However, the total network capacity an IAD can support tends to be very limited. Octal High Speed Data Module features include:
- Single slot-width, DNX application (front) and interface (rear) module
- Eight software-selectable, independent synchronous DCE ports
- EIA-530, EIA-530-A, EIA-422, EIA-232, ITU-T V.35 or ITU-T X.21 interfaces
- Eight individual DB-26 female connectors (optional cables available)
- 9.6 (DS0-A format), 48, Nx56 and Nx64 Kbps to 2.048 Mbps data rates
- Multiple port timing modes, plus system clocking reference support
- Application-specific control signal selection and monitoring
- Integral local/remote loopback and multi-pattern BER diagnostics
Wireless Services Infrastructure
The ability to effectively groom backhaul links and manage remotes sites has become a critical success factor for Cellular/PCS providers. A wireless services infrastructure that supports data and site management traffic is illustrated below. In addition to the underlying voice traffic, a DNX transports digital SS7 Common Channel Signaling (CCS) information and router-based CDPD data and site telemetry, such as door security alarming, to the Mobile Telephone Serving Office (MTSO) or Mobile Switching Center (MSC). This configuration is reproduced for each base station within a given service area. At the MTSO/MSC, traffic is directed to the proper data or voice systems and/or networks.
Representative Cellular/PCS Application
SS7 Common Channel Signaling information can be transported to the appropriate internal STP systems and/or outsourced to a third-party CCS network provider. To facilitate collection and dissemination of router-based traffic, a Router/8 (CHR) Module is available for the DNX platform.
Large-Scale Corporate Enterprises
The Octal High Speed Data Module can benefit an enterprise trying to take advantage of the new competitive multi-services arena by deploying its own or carrier-provided premises equipment. In such an application, the DNX functions primarily as an IAD, versus a DCS.
The following diagram illustrates a corporate network spanning a campus setting with a separate disaster recovery site. As is often the case, data applications are plentiful and diverse. Router and videoconferencing traffic is groomed and mapped as required to serve the evolving needs of the corporation. In addition, the reconfiguration capabilities of the DNX can be used to redirect mission-critical data via pre-allocated back-up links in the event of a system, facility, or network failure.
