d) Framer Remote loopback - Internally connects RPOS and RNEG of one framer to TPOS and TNEG respectively
of one of the other integrated framers.
Bit RLBK01, RLBK23, RLBK45, RLBK67 = 0 normal; = 1 activate.
8 Mbit/s mode:
Bit RLBK8 = 0 normal; = 1 activate.
e) Framer ST-BUS loopback(Register 904) - Internally connects DSTi of one framer to DSTo of one of the other
integrated framers.
Bit SLBK01, SLBK23, SLBK45, SLBK67 = 0 normal; = 1 activate.
8 Mbit/s mode:
Bit SLBK8 = 0 normal; = 1 activate.
