The Cisco ® 1000 Series Connected Grid Routers (CGR 1000 Series) are versatile communications platforms built to meet the communication infrastructure needs of industrial verticals such as utilities, energy, and smart cities. These routers allow utilities to integrate multiple applications, such as Advanced Metering Infrastructure (AMI), Distribution Automation (DA), integration of Distributed Energy Resources (DER), and remote workforce automation onto a single platform. The CGR 1000 Series supports outdoor wired and wireless sensor networks, enabling applications such as street lighting, smart parking, and other smart city applications.
The CGR 1000 Series Routers are ruggedized, modular platforms on which utilities and other industrial customers can build a highly secure, reliable, and scalable communication infrastructure. The products are certified to meet harsh environmental standards. They support a variety of communications interfaces, such as Ethernet, Serial, Cellular, and Radio-Frequency (RF) 902-928 Mhz mesh.
The Cisco CGR 1000 Series run Cisco IOS ® Software, the operating system powering millions of Cisco routers worldwide. Grid operators gain the benefits of Cisco IOS Software’s wide variety of Layer 3 services such as FlexVPN. The distributed intelligence capabilities of the CGR 1000 Series allow customers to run 3rd party applications such as application protocol translation, distributed data processing and filtering, and application security on the routers directly leveraging Cisco IOx — an open, extensible environment for hosting applications at the network edge.
The Cisco CGR 1000 Series includes two platforms, shown in Figure 1: The Cisco 1120 Connected Grid Router (CGR 1120), which is designed for indoor deployments; and the Cisco 1240 Connected Grid Router (CGR 1240), which is a weatherproof router in a NEMA Type 4 enclosure for outdoor deployments.
Cisco 1000 Series connected grid routers
Utilities all over the world are transitioning their grids from transmission to consumption. Regulatory mandates are driving initiatives around smart metering, grid reliability, and the integration of solar and wind farms into the distribution grid. The situation imposes a unique set of challenges for utilities to build a bidirectional communications Field Area Network (FAN) that enables these diverse applications and also scales across millions of endpoints.
The Cisco Connected Grid FAN solution has been specifically developed to meet these challenges, using design principles from industry-leading Cisco GridBlocks ™ architecture. Under the GridBlocks architecture, a typical communications network for the distribution grid is a two-tier architecture with a Neighborhood Area Network (NAN) and a Wide Area Network (WAN).
The NAN provides network connectivity to endpoints such as smart meters, street lights, and other endpoints. that form a Cisco Resilient Mesh (Wi-SUN compliant) network. The Cisco Resilient Mesh network is aggregated at a CGR 1000 Series Router, mounted on pole tops or in secondary distribution substations. The CGR 1000 Series Routers can also aggregate locally connected devices for Distribution Automation (DA). The WAN tier provides network connectivity from the CGR 1000 Series Routers to the utility’s control center over a public cellular network, or Wi-Fi network, or an Ethernet fiber network.
Figure 2 displays the solution within the network.
Cisco Connected Grid FAN solution
The Connected Grid FAN solution comprises the following products: Cisco CGR 1000 Series, IoT Field Network Director, and Cisco Resilient Mesh End Point (CRME) Reference Designs. The CRME is an open standards-based IPv6 networking stack that can be embedded in a variety of smart grid endpoints, such as smart meters. Partners with sensors or actuators who want to integrate the CRME RF Mesh into their products need to join the Cisco Developer Network/DevNet: https://www.cisco.com/go/cdn.
The CGR 1000 Series Routers take full advantage of Cisco core IP networking technologies. Our hardware and software can be used to create an open platform for industrial customers to build highly secure, multiservice FANs while lowering their total cost of ownership.
Converged multiservice network architecture
The CGR 1000 Series is a modular platform that supports various wired and wireless interfaces. It supports a 902- 928 MHz IPv6 RF mesh that can aggregate up to 5000 endpoints such as smart meters. The router has integrated Ethernet and serial interfaces to connect to DA devices such as sensors, capacitor bank controllers, recloser controllers, and remote terminal units.
Supervisory Control And Data Acquisition (SCADA) protocol (serial-to-IP) translation features allow customers to easily integrate legacy (non-IP) devices onto an IP network. An integrated Wi-Fi port can enable remote workforce automation and secure wireless console access while an integrated Global Positioning System (GPS) enables location mapping of the router. The modular design provides an easy upgrade path to future communication interfaces without platform replacement.
The CGR 1000 Series portfolio offers platforms for both indoor and outdoor deployments. These platforms come with flexible mounting kits that allow utilities to deploy the routers on a broad array of existing assets such as distribution poles, walls, and inside pad-mounted enclosures. In addition, the CGR 1000 Series offers a wide range of external antenna choices to meet coverage, throughput, and range requirements.
Cisco IOS Software provides a set of network- and application-layer services to help enable customers run multiple applications on a converged communication network. Network segmentation and Quality of Service (QoS) features allow the logical separation of application traffic with specific constraint policies applied on each traffic flow. In addition, the CGR 1000 Series is capable of integrating and hosting customer or partner specific applications.
This allows customers to eliminate the cost, space, power, and complexity of deploying and managing disparate devices.
Cisco integrates security as a fundamental building block of the FAN architecture. The CGR 1000 Series security adheres to Cisco Connected Grid security principles and widely adopted cryptography and security standards (see Table 1).

Device and Platform Integrity
The Cisco approach has been to encourage the creation and adoption of open communication standards for the smart grid. This approach promotes the growth of an ecosystem of standards-based, interoperable devices and applications from different vendors. An interoperable ecosystem ultimately reduces utilities’ risk of adopting new technologies. The Cisco Connected Grid is built on several open standards, many of them adopted from IP technologies such as IPv6. With these standards, customers are able to architect and design their network independent of the application- or physical-layer infrastructure. This functionality protects existing investments while lowering the total cost of ownership for the communications network over time.
Network reliability and high availability
The CGR 1000 Series Routers contain both device-level and network-level reliability to meet harsh physical environments. The CGR 1000 Series is built to meet stringent compliance standards such as IEEE 1613 and IEC 61850-3. The routers have enhanced thermal design and conduction cooling with no moving parts. This attribute allows extended temperature support. Additionally, the routers offer mechanisms for backup power to increase uptime for mission-critical applications in the event of power outages. Finally, the support for multiple WAN communication modules and the network resiliency and routing features in Cisco IOS Software allow utilities to deploy enterprise-class high availability in their communication networks for the distribution grid.
Communications network management
Network management applications are critical for lowering utility Operating Expenses (OpEx) while improving communications network availability. These tools simplify and automate many of the day-to-day tasks associated with managing diverse network requirements. The embedded management features available in the CGR 1000 Series, along with IoT Field Network Director and CG-DM applications allows customers to effectively meet these requirements.
IoT Field Network Director is a modular software platform for managing smart grid multiservice communication networks and security infrastructure. It is designed to foster an ecosystem of multivendor capabilities for interoperability across not only communications networks, but also legacy and next-generation power grid equipment.
The Cisco FAN solution provides operators with extensive instrumentation and diagnostic information for geographic locations, wireless interfaces, battery management, and other grid-specific details. This information can be fed into the IoT Field Network Director for day-to-day operations, operator dashboards, and real-time troubleshooting. Ease-of- use features such as secure zero-touch commissioning and a graphical field tool let non-IT field technicians deploy and manage FAN communications equipment.
In addition to the utility-specific functionality, the Cisco solution provides customers with true enterprise-class Fault, Configuration, Accounting, Performance, and Security (FCAPS) functionality. Examples include a programmatic XML interface based on the Network Configuration Protocol (NETCONF) industry standard, Role-Based Access Control (RBAC), over-the-air software upgrades, and security management functionality.
