8-2 C HAPTER 8: M ANAGING THE ATM M ODULE
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.
