The DIU 2130 can now detect the three V.54 leads which equipment
can use to activate data channel loopbacks. The definitions are as
follows:

•

LL:

The data channel loopbacks on the DIU 2130 at the local

node (the node to which the DTE sending LL is connected).

•

RL:

The data channel loopbacks on the DIU 2130 on the far end

of the network connection.

•

TM:

This is set high by the DIU 2130 upon successfully

activating LL or RL to notify the DTE of its current state.
