Description
Line Loop-Back Activate Code
If enabled by bit MR3.XLD = ´1´ in E1 or MR5.XLD = ´1´ in T1/J1 mode
the LLB activate code automatically repeats until the LLB generator is
stopped. Transmit data is overwritten by the LLB code. LAC0 is
transmitted last. For correct operations bit LCR1.XPRBS has to cleared.If
LCR3 is changed while the previous activate code has been detected and
is still received, bit LSR2.LLBAD in E1 or LSR1.LLBAD in T1/J1 mode will
stay active until the incoming signal changes or a receiver reset is
initiated (CMDR.RRES = ´1´).
