Dedicated TS-1000 Registers & Pins
The KSZ8893FQL provides 32 dedicated registers to support TS-1000 OAM communication in center MC and terminal
MC modes. The TS-1000 MC registers are located at 64 to 95 (0x40 to 0x5F), and provide the following functions:
The following table lists the dedicated KSZ8893FQL pins used in center MC and terminal MC modes.

Description
Selects center MC and terminal MC modes. See “Media Converter
Modes” subsection for details.
Power Down Detect – Use by terminal MC to detect a power-down
condition or indicate a failure has occurred.
1 = Normal operation
0 = Power down detected
After detecting a high-to-low transition on this pin, the KSZ8893FQL then
sends out an “Indicate Terminal MC Condition” OAM frame with the S0
status bit set to ‘1’ to inform the center MC that a power down condition
or failure has occurred on the terminal MC side.
If this pin is implemented, PWRDN (pin 36) needs to be de-asserted
(pulled up).
Drives low to indicate fault conditions (far-end fault detected, link
partner’s fiber or UTP port down), or MC loop back mode. This pin has
8mA drive and can directly drive a LED.
Used by terminal MC for MC loop back – strap-in pin to select:
1 = Drop OAM frames and Ethernet frames with the following errors –
CRC, undersize, oversize. Loop back Ethernet frames with only good
CRC and valid length.
0 = Drop OAM frames only. Loop back all Ethernet frames including
those with errors.
Used by terminal MC for MC loop back – strap-in pin to select:
1 = Perform MC loop back at PHY of port 1
0 = Perform MC loop back at MAC of port 2
See also register 11 (0x0B) bits[3:2].
Used by terminal MC for Missing Link Indication – strap-in pin to select:
1 = Enable Missing Link feature
0 = Disable Missing Link feature
Used by terminal MC for Diagnostic status
1 = Diagnostic fail
0 = Diagnostic normal
After detecting a change of state on this pin, the KSZ8893FQL sends out
an “Indicate Terminal MC Condition” OAM frame with the S3 status bit
set to the state of this pin to inform the center MC that a diagnostic status
change has occurred on the terminal MC side.
