NOTE: When the data rate is set to 2.048Mb/s, then the unit is
forced into G.703 mode, and it transmits user data on all 32 time-
lots. There is no framing information; therefore, the CRC4 MF
(SW2-2) switch is ignored. In all other rate settings, the unit
employs G.704 framing; TS0 is reserved for signaling.
