Cisco Channelized T1/E1 and ISDN PRI Modules for the Cisco 2010 Connected Grid Router Data Sheet

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 the 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 the 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 Smart Grid and other energy delivery infrastructure needs of customers. These ruggedized products have been extensively tested and are KEMA certified to meet the challenging substation compliance standards including IEEE 1613 and IEC 61850-3.

The Cisco Channelized T1/E1 and ISDN PRI Rugged WAN interface card (GRWIC) modules are designed for use with the Cisco 2010 Connected Grid Router (CGR 2010). This rugged router platform is optimized for the harsh conditions common in connected energy applications worldwide. The Cisco Channelized T1/E1 and ISDN PRI Grid Router WAN Interface Cards (GRWICs) combine multiple T1/E1 WAN connectivity-Channelized T1/E1 and ISDN Primary Rate Interface (PRI) in the same card. Applications include fractional or full T1/E1 WAN connectivity, ISDN PRI for primary WAN link or WAN backup, and dial access aggregation. The Cisco CGR 2010 supports a one- and a two-port version of the T1/E1 module (Figure 1) in a single-wide GRWIC. The different versions help enable customers to deploy different port densities, depending on wide area network needs in connected energy network locations.

The modules can be used in T1 or E1 networks and are selectable by software configuration. The integrated channel service unit/data service unit (CSU/DSU) function allows customers to consolidate customer premise equipment (CPE). The modules support balanced and unbalanced E1 connectivity and conform to the G.703 and G.704 standards for unframed and framed E1 modes.

Features and Benefits

●   One or two ports of RJ-48

●   Cisco IOS^® Software configurable for T1 or E1 operation

●   Integrated CSU/DSU per port

●   Fractional T1/E1 (n x DS-0) or full T1/E1

●   Balanced or unbalanced E1 termination in the same module

●   E1 unframed and framed modes (G.703 or G.704)

●   Support for Multilink Point-to-Point Protocol (PPP) and Multilink Frame Relay (FRF.16)

●   PRI for data

Key Benefits

Enhanced Flexibility

The Cisco E1/T1 ISDN PRI GRWICs are software-configurable between E1 or T1 operation, balanced or unbalanced E1 termination, and CSU/DSU. Customers no longer need to buy a specific module for T1 support and then another card for E1 connectivity. In addition, the same modules provide for balanced (120-ohm) and unbalanced (75-ohm) E1 termination.

Support for G.703 Unstructured E1 Signaling

The one- and two-port T1/E1 GRWIC supports G.703 unstructured signaling. Framed E1 (G.704) is also supported for international customers without G.703 service.

Increased Manageability and Troubleshooting

Critical loopback support makes the Cisco Channelized T1/E1 and ISDN PRI modules easy to manage. Both models can internally loop back the onboard framer chip toward the interface, thus eliminating the need for an external loopback plug. Local, remote, line, and payload loopbacks complement the management features of the Cisco Channelized T1/E1 and ISDN PRI module.

Reliability

Integrating the external E1/T1 terminating device (CSU/DSU) increases the overall system reliability. Possible points of failure are reduced by eliminating the second power supply, additional fans, extra cabling, and other equipment that accompany a "two-box" solution. This increase in reliability allows service providers to more easily and cost-effectively meet the requirements of their customers' service-level agreements (SLAs) and provides utilities with maximum equipment uptime.

Safety, EMC, Telecom, Network Homologation, Power, Environmental Requirements, and Regulatory Approvals

When installed in a Cisco CGR 2010, the one- and two-port Channelized T1/E1 and ISDN PRI GRWICs do not change the standards (safety, EMC, telecom, network homologation, power, environmental requirements, and regulatory approvals) of the router itself. Refer to the Cisco CGR 2010 data sheet for additional information about mechanical, environmental, and agency certifications.
