Applications and Default Conﬁguration

This chapter provides connection instructions for typical ATMSpeed/155

applications. The chapter also describes the factory-set default conﬁguration for

the ATMSpeed/155 module.

ATMSpeed/155 Port Applications

You can connect the ATMSpeed/155 module for optimal LAN performance. This

section provides instructions for the following types of ATM connections:

• Connecting Centillion 100 switches directly

• Connecting Centillion 100 switches through an intermediate ATM switch

• Connecting an ATM LAN emulation station to a Centillion 100 switch

Connecting Centillion 100 Switches Directly

To connect two Centillion 100 switches directly, follow these steps:

1. Conﬁgure each ATMSpeed/155 module port.

To conﬁgure ATM ports, refer to Using SpeedView 2.1 for Windows. Both

switches must have the same kind of virtual port conﬁgured.

2. Connect one end of the ﬁber cable to the ﬁrst switch.

Note that the SC connector of the ﬁber cable is keyed.

3. Connect the other end of the ﬁber cable to the other switch.

The In Service LED for the ATM port turns on when the switch recognizes the

physical connection. You can view the LED on the switch itself or through the

SpeedView application by selecting the Switch menu and choosing View.
