Port Active
Use this pull-down to select whether to enable or disable the state of the media converter. When disabled, all
LEDs on the unit and in the Web GUI will be extinguished. This function is not allowed when managing the remote
converter and will be 'grayed out'. To disable a link, the local or 'in-chassis' converter must have its port disabled.
Auto Laser Shutdown
This pull-down chooses between enabling and disabling the ALS function. The default is disabled.
Operation Mode
This pull-down chooses between switch mode and Tag Based VLAN mode. When the media converter works
in 'switch mode' mode, it does not begin to forward a packet to a destination port until after the entire packet is
received. The latency therefore depends on the packet length. The maximum packet length supported is up to
2046 bytes in this mode. Different from a normal switch chip, the media converter's chip supports forwarding
IEEE802.3x pause frames. In 'switch mode' the MC operates with a 'store & forward' method that supports a 1K
MAC address table. The UTP side may be 10 or 100 speed and in full or half duplex, while the fiber side runs in
100Base, full duplex.
In 'Tag Based VLAN mode', the MC is able to do VID tagging and untagging so that traffic between the two
UTP ports can be isolated, sent over fiber, and then separated at the remote CPE between the two UTP ports.
Each UTP supports setting a VID from 1 to 4094.
Link Fault Pass Through
This pull-down chooses between enabling and disabling the LFP function. The LFP function is explained in
A.1.2. The default is disabled.
In Band Management
This pull-down is used to enable or disable the OAM (In Band Management) function. Once disabled the OAM
maintenance frames will no longer be transmitted, while received frames will be ignored. Monitoring and managing
of the remote converter will be disabled. The default setting for this function is enabled.
Bandwidth Limiting
This converter supports both ingress (UTP to Fiber) and egress (Fiber to UTP) bandwidth control in
granularities of 32K or 512K. This provides a very flexible and controllable bandwidth usage through the media
converter. The default setting is with no limiting.
