Cisco Connected Grid ISDN GRWICs Hardware Installation Guide
Last Revised: May 16, 2012OL-26961-01
This document provides a hardware overview for Cisco Connected Grid ISDN Basic Rate Interface (BRI) interface cards that provide connectivity to the Wide Area Network (WAN) for the
Cisco 2010 Connected Grid Router (hereafter referred to as the Cisco CGR 2010).
This document includes the following sections:
Information About the Connected Grid ISDN GRWICs
Each of the following ISDN interface cards is a single-wide, grid router WAN interface card (GRWIC).
•Cisco Connected Grid 1-port ISDN BRI S/T High-speed GRWIC
The 1-port ISDN BRI S/T requires an external network terminator 1 (NT1) device for connection to the phone company.
•Cisco Connected Grid 1-port ISDN BRI U High-speed GRWIC
The 1-port ISDN BRI U has a built-in network terminator 1 (NT1) device that accepts a two-wire signal from the phone company and converts it into a four-wire signal. The NT1 interface is also known as a U interface.
Note For details on software configuration for these GRWICS, please refer to the appropriate document listed in Software Configuration.
This section covers the following topics:
Table 1 summarizes the hardware specifications of the two Connected Grid ISDN GRWICs supported on the Cisco CGR 2010 Router.

Installing and Removing the Connected Grid ISDN GRWICs
This section describes how to install and remove a Connected Grid ISDN GRWICs in the
Cisco CGR 2010 Router and includes the following topics:
This section includes the basic installation warning statements for the Connected Grid ISDN BRI S/T and ISDN BRI U GRWICs. For regulatory compliance and safety information for the Cisco CGR 2010, refer to the Connected Grid Router 2000 Series Regulatory Compliance and Safety Information document.
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030
Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001
Warning Read the installation instructions before connecting the system to the power source. Statement 1004
The following warning, Statement 44, only applies to the Connected Grid ISDN BRI S/T GRWIC.
The following caution and warning only apply to the Connected Grid ISDN BRI U GRWIC.
Caution To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the 1-port ISDN BRI U only to intra-building or non-exposed wiring or cabling.
Installing a Connected Grid Single-Wide ISDN GRWIC
The Connected Grid ISDN GRWICs are single-wide interface cards. The router can accommodate four single-wide GRWICs or two single-wide GRWICs with one double-wide GRWIC, or two double-wide GRWICs at any one time.
A single-wide GRWIC installs in to one of four slots on the cable side of the router.
Each GRWIC is enclosed within a carrier enclosure with bars that extend outward from the front panel (see Figure 3).

To install a single-wide GRWIC, follow these steps:
Step 1 Stand the GRWIC on end to slide the single-wide GRWIC in to the router slot (see Figure 4).

Removing a Connected Grid Single-Wide ISDN GRWIC
Caution The module CANNOT be hot swapped—however, you do not need to power down the system to insert the module.
Step 1 Using a screwdriver, loosen the three captive screws on the Connected Grid ISDN GRWIC.
Step 2 Gently pull the module out of the slot.
Connecting Connected Grid ISDN GRWICs to the Network
This section provides the steps for connecting the ISDN BRI GRWICS to the ISDN network and includes the following topics:
Caution Please review all Safety Warnings in this document before connecting the ISDN GRWICs to the network.
Connecting the ISDN BRI S/T GRWIC to a Network
To connect an ISDN BRI S/T GRWIC to a network, follow these steps:
Step 1 Power off the Cisco CGR 2010 Router.
Step 2 Connect one end of a straight-through RJ-48C-to-RJ-48C cable to the RJ-48C port on the ISDN BRI S/T GRWIC and connect the other end of the cable to the NT1 device (S/T port).
Step 3 Connect the NT1 device to the ISDN wall jack according to the documentation that came with the NT1 device.
Step 4 Power on the router.
Connecting the ISDN BRI U GRWIC to a Network
To connect an ISDN BRI U GRWIC to a network, follow these steps:
Step 1 Power off the Cisco CGR 2010 Router.
Step 2 Connect one end of a straight-through RJ-49C-to-RJ-49C cable to the RJ-49C port on the ISDN BRI U GRWIC and connect the other end of the cable directly to the ISDN wall jack.
These ports are color-coded red.
Step 3 Power on the router.
