            Ordering Information

            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. This rugged router platform is optimized for harsh conditions common in utility substations 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.

            Compatibility Notes Enhanced flexibility:
            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 T1/E1 GRWIC supports G.703 unstructured signaliling. Framed E1 (G.704) is also supported for international customers without G.703 service.

            Increased manageability and troubleshooting:
            Critical loopback support makes the Cisco Channnelized T1/E1 and ISDN PRI Modules easy to manage. They 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.

            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.
