Description
Framer (System) In-Band Loop Switching (Local Loop)
This bit controls if automatic switching of the local loop will be done by In-
Band loop codes from the framer side, see
necessary receiption time of In-band loop codes until an automatic loop
switching is performed is configured by INBLDTR.INBLDT(1:0).
Note: This feature is not described in E1/T1/J1 standards. Generation of
