8-2CHAPTER 8: MANAGING THE ATM MODULE

Configuring an ATM Port

The ATM Module Configuration Screen shows the settings and standards used by the ATM Module to communicate with other devices on the ATM network.

It is unlikely that you will need to change the value of these settings once they have been set.

ATTENTION: If you need to change the value of any of the settings, you may experience a temporary loss of communication while the device resets. If you do not need to make any changes, select the CANCEL button and not the OK button. Selecting the OK button resets the device.

The ATM Module Configuration screen can be accessed from the Main Menu or from the ATM Port Setup screen:

Select the ATM CONFIGURATION option from the Main Menu.

Alternatively, if you are already in the ATM Port Setup Screen, as described in “ATM Port Setup” on page 8-6, you can select the CONFIG button.

An example of the ATM Module Configuration screen is shown in Figure 8-2.

Ensure that the ATM Module and the ATM Switch it is connected to are set up to use the same signalling and SONET/SDH standards. The two devices should also use the same ILMI VCC and compatible values for MAX VPI Bits and MAX VCI Bits. If the devices do not use the same standards, they cannot communicate with each other.

The following fields are shown on the screen:

ATM Mode Shows the ATM Mode of operation, which is set to LAN Emulation Version 1. The ATM Mode cannot be changed in this release.

Signalling Specifies the User-to-Network Interface (UNI) Signalling protocol used to communicate with other devices. Select either uni3.0 or uni3.1 standards. The default is uni3.1.
