REMOTE SIGNALING
The MB86961A transmits standard link pulses which
meet the 10BASE-T specification. However, the
MB86961A encodes additional status information into
the link pulse by varying the link pulse timing. This is
referred to as remote signaling. Using alternate pulse
intervals, the MB86961A can signal three local condi-
tions: link down, jabber, and remote signaling capability.
Figure 11 shows the interval variations used to signal
local status to the other end of the line. The MB86961A
also recognizes these alternate pulse intervals when
received from a remote unit. Remote status conditions are
reported to the controller over the RLD, RJAB and
RCMPT output pins.

Notes: 1. For Remote Link Down (RLD) signaling, the interval between LI pulses increments from
10 ms to 15 ms to 20 ms, and then the cycle starts over.
2. For Remote Jabber (RJAB) signaling, the interval between LI pulses decrements from 20
ms to 15 ms to 10 ms, and then the cycle starts over.
3. For Remote Compatibility (RCMPT) signaling, the interval between LI pulses continually
switches between 10 ms and 20 ms.
