1.5 Application Examples
1.5.1 In-Band Managed 10/100 Converter Application
Fig 3. Depicts a typical in-band managed fiber to UTP conversion at a Customer's
Premises (CP) or at a remote network edge. In-band management is a desirable
feature in these applications since it facilitates remote monitoring, configuration and
trap notification from the chassis. VLANs can be used to separate the customer data
from the management data.
This application uses an
management and a 4TxVT 4-Port 10/100 switch module for added customer
connectivity. Both modules are plugged into the 2-Module chassis.
The 10/100M converter module features two front-plane Ethernet ports (100BASE-FX
fiber and 10/100BASE-T UTP) and two 10/100Mbps Ethernet backplane ports (A and
B Ports).
The 4TxVT module features four front-plane Ethernet ports (10/100BASE-T) and two
10/100Mbps Ethernet backplane ports (A and B Ports).
The user data flows between the fiber and UTP ports of the 10/100M and 4TxVT via
the backplane.
The management data flows between the fiber and all the UTP ports (in-band).
Using a management VLAN, the management data is recognized by the 10/100M
module and is not shared by the other ports.
This configuration provides the network administrator with the ability to manage and
maintain the converter chassis at the remote location.
