BIT NAME
BIT DESCRIPTION
0
LDPS Enable
Link-Down-Power-Saving mode. Set this bit to 1 will reduce the power
usage of IP100A LF if the link between IP100A LF and another terminal
has terminated.
1
Auto-Cross-Over
Enable

Last-Gasp Repeat
Time
These 3 bits will decide the number of Last Gasp Packets to send. Since
there are 3 bits controlling the amount of packet sent, thus the maximum
number of packets is 8 frames.
7
Last-Gasp OP Code Decision of the Last Gasp OP Code. This bit determines the OP Code
within the Last Gasp frames.
At 0: Last-Gasp packet send OP Code is 0001
At 1: Last-Gasp packet send OP Code is 0100
