The AIS transmit function can be enabled or disabled on each port (Copper Port and Fiber Port) by set-
ting TAOS to Enable or Disable. If the AIS transmit function is enabled on one port and signal lost is de-
tected, the x6010 will transmit all ones to the receiving end device; if the AIS function is disabled, no
action will be performed.
If the x6010 receives an AIS signal (All Ones frame) from one port, the LED (SDC/SDF- Signal Detect on
Copper/Fiber) displays as yellow to indicate AIS is detected on that port (see “
LED Descriptions
”. The
x6010 software transmits an AIS detect trap at the same time (see the “
SNMP MIBs
” section for trap
descriptions).
If Media Converter A in Figure 2 above detects a signal lost on a copper port and the AIS function is ena-
bled (TAOS is enabled) on that port, Media Converter A will Transmit All Ones to Media Converter B
through the fiber link. Media Converter B’s SDF LED will display as yellow to indicate an AIS signal is
detected on the fiber port. The AIS signal will then be transmitted to End Device B.
In T1 mode, the criteria for declaring/clearing AIS detection are in compliance with the ANSI T1.231.
In E1 mode, the criteria for declaring/clearing AIS detection comply with the ITU G.775 or the ETSI
300233, as selected.
Loopback Test
The x6010 provides Loopback (LB) test support with three different loopback configurations: copper
loopback, fiber loopback, and inband loopback.
The Loopback feature puts the x6010 in a mode that lets it loop back the signal from the RX port to the
TX port on either media for testing and troubleshooting purposes. You can enable or disable the
Loopback function on an x6010 copper port or fiber port via the Web interface, FocalPoint (FP), and the
Command Line Interface (CLI).
Test signals from a test device (e.g., Fireberd, etc.) can then be inserted into the link and looped back
and received by a device to test a particular segment of the link (i.e., copper or fiber).

Figure 3: Loopback on copper and fiber port of Media Converter A
If the Loopback function is enabled on the copper port of Media Converter A, End Device A is the tester;
the test signal is inserted into the copper RX of Media Converter A and then looped back and received
by the copper TX of Media Converter A.
