4.5ATM 4-Port 100 Mbps MIC Fiber Module and the ATM 4-Port 100 Mbps SC Fiber Module

The ATM 4-Port 100 Mbps MIC Fiber Module and the ATM 4-Port 100 Mbps SC Fiber Module are single-slot concentrator modules that are identical except for they have MIC and SC connectors, respectively. They have the following characteristics:

•

•

Hot-pluggable in any slot in the 8285 Expansion Chassis.

Each module provides four taxi ports, each capable of supporting 100 Mbps (full-duplex). The traffic received from these ports will be multiplexed into the backplane connection between the A4-FB100 module and the

switch-on-a-chip.

•

•

Support for workstation connections (UNI) up to 2 km from the 8285.

Support for a connection between two A4-FB100 ports (SSI/NNI) up to 3 km.

4.5.1 Sample Scenarios

The 4-port 100 Mbps modules are high-performance cards that are very

cost-effective for connecting high-bandwidth users and servers into a workgroup or an ATM network. In addition, they can be used to provide redundant links to a backbone or server to provide higher bandwidth and improved reliability.

Figure 17 and Figure 18 on page 47 show some ways the 4-port 100 Mbps modules can be used with the 8285.

Figure 17. ATM 100 Mbps MIC/SC Fiber Module Workgroup Configuration

The first example, a workgroup configuration, shows how you might set up a very cost-effective high-performance stand-alone workgroup, providing up to 100 Mbps bandwidth to as many as 16 power users, 25 Mbps of bandwidth to as
