Introduction

This document explains how to configure the Interface Controller Card (ICC) -T1 for Foreign Exchange Office (FXO) and Foreign Exchange Station (FXS) Loop Start (LS) and Ground Start (GS) circuits. The ICC is a high-capacity network interface engine that employs a midplane architecture which enables the network to connect with a series of I/O modules specific to different network interface requirements.

Prerequisites

Requirements

Readers of this document should have knowledge of these topics:

  • How to program a VCO/4K switch

  • Telephony analog signaling, such as FXS and FXO LS and GS circuits

Components Used

This document is applicable on Cisco VCO/4K with ICC-T1 spans running release 5.1.4 or later.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Conventions

Configuration Steps

In order to configure an ICC-T1 span for FXO and FXS LS and GS circuits, perform these steps.

  1. With the Card Maintenance Screen, shown in this example, take the entire ICC (all 16 spans) Out of Service (OOS). In order to do this, enter 1,1,xx, where xx is an integer between seven and 21 inclusively and set the status to O to issue the C command.

  2. Go into the Card Summary Screen, shown in this example, and use Next Screen and Next Field in order to move the cursor to the span you want to configure.

  3. Press any letter on the keyboard followed by the Enter key in order to enter the Trunk Configuration Screen.

  4. Use the Tab key to move the cursor down to Port 1, and use Next Field to go to the Signaling Type (SIG. TYPE).

  6. You have two options in order to reactivate the ICC. The first is to go back to the Card Maintenance Screen and follow the guidelines in Step 1, but replace Status O with A. You can also physically reseat the ICC. Once the ICC comes back up, the span that was changed runs the new protocol.
