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), which has been designed to support the communications infrastructure needs of the energy delivery infrastructure across the generation, transmission, and distribution sectors. Designed for highly secure, reliable, and scalable infrastructure, the CGR 2010 is an ideal platform to support Smart Grid and other energy delivery infrastructure needs of customers. The CGR 2010 has been extensively tested to meet the challenging substation compliance standards including IEEE 1613 and IEC 61850-3. The CGR 2010 offers four module slots to utilize Grid Router WAN Interface Cards (GRWIC). These GRWICs support legacy WAN interfaces (e.g. ISDN, DSL, Serial) as well as newer WAN technologies such as 4G/LTE.

Product Overview

The Cisco ISDN BRI Grid Router WAN interface cards (GRWICs) are designed for use with the Cisco 2010 Connected Grid Router (CGR 2010). Applications include BRI U or BRI S/T WAN connectivity for energy infrastructure that utilizes ISDN for connectivity.

Features and Benefits

• One ISDN BRI port with U interface (built-in NT1)

– Utilizes an RJ-49C connector

– Remote and local configuration, monitoring, and troubleshooting with the Cisco IOS® Software command-line interface (CLI) and Simple Network Management Protocol (SNMP)

• One ISDN BRI port (S/T interface, requires external NT1)

– Utilizes an RJ-45 connector
