Configuration Guide
Configuration Guide: Analog and
Digital Voice
This Configuration Guide is designed to provide you with a basic
understanding of the concepts behind configuring your NetVanta 950 IAD
for analog and digital voice traffic. Two configuration methods are
available for your NetVanta IAD:
• Web-Based GUI
• AOS CLI
The web-based GUI lets you configure the main settings and provides
online guidance and explanations for each setting. However, use of the
AOS CLI may be necessary for more advanced configurations.
Access the AOS CLI via the CONSOLE port or a Telnet session. For more
details on CLI access, refer to the AOS Command Reference Guide on
your ADTRAN OS Documentation CD (included in the shipment).
This guide consists of the following sections:
•Understanding Analog and Digital Voice on page 2
•Configuring Your IAD on page 4
•Verifying Your Configuration Using Show Commands on page 36
•Testing Your System on page 38
•Managing Event Messages on page 41

Types of Signaling
• Analog: Loop Start, Ground Start, E&M, DPT (FXO only)
• Digital: Robbed-Bit, Clear Channel
2. CONFIGURING YOUR IAD
The remainder of this document provides examples designed to clarify the configuration of analog (FXS or
FXO) or digital (T1) voice. Section 2a describes how to configure the IAD with the Web GUI. Section 2b
(starting on page 16) describes how to configure the IAD with the CLI.
2a. Configuring your IAD with the Web GUI
You can configure your IAD with the interactive Web GUI. The web-based GUI lets you configure the
main settings and provides online guidance and explanations for each setting. However, you may have to
use the AOS CLI for more advanced configurations.
Logging In
Open a browser window and type the IP address for the unit in the address field. A login window
(shown in Figure 4) displays.
Figure 4. Login Screen
Enter your USER NAME and PASSWORD; then click OK. The default username is admin, and the default
password is password. The IAD MANAGEMENT INTERFACE for the NetVanta 950 displays as shown in
Figure 5 on page 5. For information on setting your IP address and connecting the IAD to the LAN,
refer to the NetVanta 950 IAD Quick Configuration Guide provided on your ADTRAN OS
Documentation CD.

T1 Ports
When you log into the Web GUI, the GENERAL SYSTEM INFORMATION page displays in your browser
window.

In the left column select PHYSICAL INTERFACES, and the screen shown in Figure 6 displays. This
screen shows all the physical interfaces that are installed in the system.

View or edit the configuration of an interface by selecting its name. Select the t1 0/1 port, and
the T1 0/1 CONFIGURATION page displays as shown in Figure 7.
Figure 7. Configuration for T1 0/1
By default, the T1 interface is set for ESF framing and B8ZS coding. If you want to change settings,
select different options from the pulldown menus. For example, if you want to change FRAMING, select
the pulldown menu as shown in Figure 8. Select the new option from the list. When you are finished
making changes, select APPLY.

System Clock Source
The clock source provides the reference point for all voice and data traffic in the system. There can
only be one clock source for the system, otherwise clock slips may occur on the other T1 interfaces,
resulting in noise on voice lines and errors on data circuits. Options include INTERNAL, t1 0/1, or t1 0/2.
The default clock source is t1 0/1. Change the clock source by clicking on the PRIMARY CLOCK SOURCE
menu and selecting another option. You can also select a backup source if more than one source exists;
otherwise, Internal timing will be used as a backup. When you are finished making changes, click
APPLY.
Figure 9. System Clock Source
You can also check the configured settings as well as the current clock source on the
GENERAL SYSTEM INFORMATION page as shown in Figure 5 on page 5.

TDM Groups
TDM groups are used to assign a number of DS0s to a particular interface. By creating a TDM group,
the user sets aside a block of T1 channels for use in a particular cross connect. To access the DS0
Connections, scroll down the browser screen until you see the configuration box shown below. You
can assign 24 DS0s to a T1 interface by selecting a DS0 RANGE of 1 to 24 (as shown in Figure 10). For
the CONNECT TOfield, select t1 0/1. For the STARTING DS0 select 1. Click ADD. A TDM group is
created for the interface and channels 1-24 are assigned to the TDM group. The new DS0 connection
displays at the bottom of the box.
Figure 10. TDM Groups
You can scroll down the page and use the STATUS box to view a snapshot of the current
status and statistics or to get a continuous update of the status and statistics of the T1 port.

Configuring the FXS Card
To configure the FXS card, select PHYSICAL INTERFACES in the left pane. All of the available interfaces
display as shown in Figure 6 on page 6. Select an FXS port, such as fxs 7/1,and the page shown in
Figure 11 displays. Change any of the settings (discussed in detail below) as required. When you are
finished, select APPLY. To apply changes to several ports at the same time, select the check box for each
port at the top of the screen. To apply the changes to all of the ports, click SELECT ROW.

Settings
Click on ENABLE to enable the interface. The interface is disabled by default. The receive gain is
configurable in 0.1 dB increments from -12 dB to +6 dB (default is -3 dB). Receive gain determines
the amplification of the signal before sending the signal out the FXS interface. When increasing this
value, the signal being received on this port from the network sounds louder. When decreasing this
value, the signal being received on this port sounds softer.
The transmit gain is also configurable in 0.1 dB increments from -12 dB to +6 dB (default is -6 dB).
Transmit gain determines the amplification of the signal before sending the signal towards the
network. When increasing this value, the signal being transmitted to the far end sounds louder. When
decreasing this value, the signal being transmitted to the far end sounds softer.
