Control Turn-Off Delay in "DATA" Switching Mode (SW23-1,2)
When configured to switch on DATA, switch SW23-1 and 2 set the Sub-Channel release time
in clocks. The value selected is the number of clocks at the current baud rate that must occur
without any data transitions on the Sub-Channel to indicate that Sub-Channel has completed
its transmission and the 3060/V24 (CTS MD-V.24/TCB) can resume servicing the other Sub-
Channels. The following table should be used to set this time period.

Internal Baud Rates (SW22-4,5,6,7)
Switch SW22-4, 5, 6 and 7 select the master clock rate when Internal Clock Source is selected
on TX Clock Source or RX Clock Source. In addition the Fallback clock rate is also selected
with this option. When Fallback clocking is required, the RX Clock Source and TX Clock
Source should not be set to INTERNAL. Selecting CHAN 6 RXC allows Fallback clocks to
originate from Sub-Channel 6 pin 17. The following table shows the available rates. If CHAN
6 RXC is selected, SW22-7 can be in either position.
