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.
SW1-6 and SW1-7
Clock Modes
Network Clock Transmitter timing is derived using the received line
signal (received recovered) from the network.
Internal Clock
Transmitter timing is derived from an internal clock
source.
