The Cisco® Connected Grid portfolio of solutions is designed specifically for the harsh, rugged environments often found in the energy and utility industries. These solutions include the Cisco 2010 Connected Grid Router (CGR 2010) and the Cisco 2520 Connected Grid Switch (CGS 2520), which have been designed to support the communications infrastructure needs of the energy delivery infrastructure across the generation, transmission, and distribution sectors. This infrastructure includes utility- and customer-owned energy infrastructure such as substation applications supporting electrical transmission and distribution, renewable generation, oil and gas, water, distributed generation, co-generation, and trackside operations. The infrastructure also includes communications infrastructure for delivery applications such as transmission pipelines, distribution mains, and service lines for oil and gas and water. Designed for highly secure, reliable, and scalable infrastructure, the CGR 2010 and CGS 2520 are an ideal platform to support the Smart Grid and other energy delivery infrastructure needs of customers. These ruggedized products have been extensively tested and are KEMA certified to meet challenging substation compliance standards, including IEEE 1613 and IEC 61850-3.

The 8-port Asynchronous/Synchronous Grid Router WAN Interface Card (GRWIC) provides low-speed synchronous/asynchronous serial connections supporting EIA-RS232 for the Cisco CGR 2010. The 8-port serial RS-232 GRWIC helps customers to enable applications such as legacy protocol transport, console server, and dial access server. Combining a high-density serial GRWIC with the Cisco CGR 2010 enables energy networks to transport mission-critical communication such as Supervisory Control and Data Acquisition (SCADA) over an IP network.

Common Applications

These highly flexible interface cards enable several important applications.

Legacy Protocol Transport

For example, utility companies are migrating their substations from serial to ethernet communications. Given the amount of serial communications that exist in substations today, the migration will take place over a number of years. An 8-port Async/Sync serial module in the Cisco CGR 2010 helps utilities to transport legacy SCADA traffic across a TCP/IP network. The serial interfaces provide a converged communications solution while utilities migrate from serial-based Remote Terminal Units (RTUs) to ethernet-enabled RTUs and Intelligent Electronic Devices (IEDs). This capability enables network convergence, eliminating costly separate leased lines for this traffic. Legacy protocols supported by Cisco IOS® Software include:

Bi-Synchronous Tunnel Protocol (BSTUN)

Systems Network Architecture (SNA) and Synchronous Data Link Control (SDLC) Protocol

Binary Synchronous Communications Protocol (Bisync)

Console and Terminal Server

Asynchronous ports provide highly flexible connections that allow access to EIA-232 devices across a TCP/IP network. This access allows out-of-band management to console or craft ports, enabling the network operator to manage anetwork of remote devices from a central location (Figure 3).

Connectors and Cabling

The 8-port serial GRWIC has connectors and cabling that allow high port densities in the compact GRWIC form factor. Table 1 show connector and cabling specifications.

High-Density Synchronous/Asynchronous Cabling

The 8-Port Asynchronous/Synchronous GRWIC uses two high-density 4-port connectors. Each connector supports four ports of EIA-232 with data communications equipment (DCE) or data terminal equipment (DTE) interfaces. All four ports on one cable use the same DTE/DCE mode. Table 1 outlines the cable specifications for the 8-Port Async/Sync RS-232 GRWIC.
