Accessibility

You can configure the Cisco VG202, Cisco VG202XM, Cisco VG204, and Cisco VG204XM voice gateways by using the Cisco command-line interface (CLI). The CLI conforms to code 508 because it is text based and relies on a keyboard for navigation. You can configure and monitor all functions of the voice gateway through the CLI.

About the Voice Gateways

Cisco VG202, Cisco VG202XM, Cisco VG204, and Cisco VG204XM voice gateways deliver analog voice gateways for the service provider as well as commercial and enterprise unified communication markets. These voice gateways provide voice connectivity to devices such as analog phones, fax machines, and modems.

Cisco VG202, Cisco VG202XM, Cisco VG204, and Cisco VG204XM voice gateways provide support for 2-FXS (Cisco VG202 and Cisco VG202XM) and 4-FXS (Cisco VG204 and Cisco VG204XM) ports, each supporting independent telephone numbers giving you two or four separate lines, and parity with Cisco IOS fax/modem, security, and Session Initiation Protocol (SIP) features. Both voice gateways are configurable with Cisco Unified Communications Manager (CUCM) & Cisco Unified Communications Manager Express (CUCME).

CHAP T ER

Note Cisco VG202, Cisco VG202XM, Cisco VG204, and Cisco VG204XM voice gateways are fixed voice

gateways and do not support interface cards.

Port Numbering Conventions

The Cisco VG202 voice gateway supports two RJ-11 ports and supports two FXS voice ports with two 10/100 Fast Ethernet ports. Figure 1-1 shows the interfaces and ports on the Cisco VG202 voice gateway. All interface ports are on the back of the chassis.

Port numbering conventions for the Cisco VG202, Cisco VG202XM, Cisco VG204, and Cisco VG204XM voice gateways are as follows:

• Foreign Exchange Station (FXS) voice port numbering begins at 0/0 and extends to 0/1 for the

Cisco VG202 and Cisco VG202XM, and extends to 0/3for the Cisco VG204 and Cisco VG204XM.

About Cisco IOS Software

Understanding these concepts about the Cisco IOS software will save time as you begin to use the CLI. If you have never used Cisco IOS software or if you need a refresher, take a few minutes to read this chapter before you proceed to the next chapter.

If you are already familiar with Cisco IOS software, proceed to Chapter 2, “Configuring Your Voice

Gateway Using the setup Command.”

For a comprehensive view of Cisco IOS configuration fundamentals, see the Cisco IOS Configuration

Fundamentals Configuration Guide, Release 12.4.

Note • Your Cisco IOS software release may not support all of the features documented in this document.

For the latest feature information and caveats, see the release notes for your platform and software release.

• Use the Cisco Feature Navigator to find information about platform support and Cisco IOS and

Catalyst OS software image support. To access the Cisco Feature Navigator, go to

http://www.cisco.com/go/cfn. You do not need an account on Cisco.com to access the Cisco Feature

Navigator.

Understanding Cisco IOS Software Basics

• The VG202 and VG204 devices support IOS software releases 15.0(1)M or earlier* due to memory

limitations. The VG202XM and VG204XM devices will support the latest IOS software release

15.3(2)T and beyond. Earlier releases are not supported on the VG202XM and VG204XM. *Deployments requiring support for secure SCCP based call control are supported using 15.1(4)M IOS release.

Getting Help

Use the question mark (?) and arrow keys to help you enter commands:

• For a list of available commands, enter a question mark:

VG> ?

• To complete a command, enter a few known characters followed by a question mark (with no space):

VG> s?

• For a list of command variables, enter the command followed by a space and a question mark:

VG> show ?

Chapter 1 Understanding Interface Numbering and Cisco IOS Software Basics

• To redisplay a command you previously entered, press the up arrow key. You can continue to press

Command Modes

The Cisco IOS user interface involves different modes. Each command mode permits you to configure different components on your voice gateway. The commands available at any given time depend on which mode you are currently in. Entering a question mark (?) at the prompt displays a list of commands available for each command mode. Tab le 1-1 lists the most common command modes.

Table 1-1 Common Command Modes (continued)

Command Mode Access Method VG Prompt Displayed Exit Method

Global configuration From the privileged

EXEC mode, enter the configure terminal command.

Interface configuration From the global

configuration mode, enter the interface type number command, such as

interface fast ethernet 0/0.

Timesaver Each command mode restricts you to a subset of commands. If you are having trouble entering a

command, check the prompt, and enter the question mark (?) for a list of available commands. You might be in the wrong command mode or using the wrong syntax.

VG(config)# To exit to privileged

EXEC mode, use the exit or end command, or press Ctrl-Z.

VG(config-if)# To exit to global

configuration mode, use the exit command.

To exit directly to privileged EXEC mode, press Ctrl-Z.

In the following example, notice how the prompt changes after each command to indicate a new command mode:

VG> enable Password: <enable password> VG# configure terminal VG(config)# interface fastEthernet 0/0 VG(config-if)# line 0 VG(config)# exit VG# %SYS-5-CONFIG_I: Configured from console by console

The last message is normal and does not indicate an error. Press Return to get the VG# prompt.

Note You can press Ctrl-Z in any mode to immediately return to enable mode (VG#), instead of entering exit,

which returns you to the previous mode.

Undoing a Command or Feature

If you want to undo a command you entered or disable a feature, enter the keyword no before most commands; for example, no ip routing.

Saving Configuration Changes

OL-16191-01

You need to enter the copy running-config startup-config command to save your configuration changes to NVRAM, so the changes are not lost if there is a system reload or power outage. For example:

VG# copy running-config startup-config Building configuration...
