Pre-Configuration Checklist
Before configuring the ATM OC-3c Module, com-
plete the following steps:
1
Install the ATM Module —
Installation instruc-
tions are provided in “Installing and Setting Up the
Module” in the ATM Module User’s Guide.
2
Check that the ATM Module is correctly
installed in the Switch —
Follow the “Post Instal-
lation Checks” as described in “Installing and Set-
ting Up the Module”, in the ATM Module User’s
Guide.
3
Check that the Switch is correctly installed in
the network —
See the User’s Guide that came
with your Switch.
In this reference guide, the term Switch is used to
identify the device containing the ATM Module.
The term ATM Switch is used to identify the ATM
device that the Switch is connected to on the net-
work.
4
Ensure that the LANE Services are correctly set up
on your network, that is, each LAN Emulation Server
(LES) and its associated Broadcast and Unknown
Server (BUS) are operational.
5
To communicate with an ATM Switch, the communi-
cation settings on the ATM Module and ATM Switch
must be compatible. Find the following ATM Switch
settings and enter them below:
Signalling Mode
Signalling must be the same on both devices, and
must be either 3.0 or 3.1. The default on the ATM
Module is 3.1.
SONET or SDH?
Both devices must use the same physical standard.
The ATM Module supports
SONET STS-3c
and
SDH
STM-1
, and the default is
SONET STS-3c
.
Both devices must use the same
Interim Local Management Interface (ILMI)
connection.
The default is VPI = 0 and VCI = 16.
