This menu option can also be set to ON-DEMAND which
will activate the Inband Channel only when commands
are sent from T-Watch Pro to the remote unit (TSU 600 B
in Figure 3-5). If no T-Watch Pro activity is detected for
10 minutes, the Inband Channel is deactivated.
TX CLK SOURCE
Controls the clock used by the DTE. Normally this is set
to INTERNAL. If the DTE provides a clock with TX data,
the clock selection is set to EXTERNAL. The Nx56/64
will depend on an externally supplied clock to accept the
TX data.
Choices: INTERNAL or EXTERNAL

Although a router can accommodate this 8K rate reduction, some DTE
devices may not (i.e., video). Determination should be made if the
connected DTE can handle this reduced clock source. A second option
would be to operate in 56K/DS0.
