Duplex Select
Duplex select allows you to select the channel (1-12) that is
full duplexed to the selected (A or B) input channel. No
channel is selected on zero. Table 3-D displays the switch
settings. The expansion settings (A EXPD, B EXPD, and A/
B EXPD) full duplex back to their respective T1 input lines.
For example, the A EXPD setting full duplexes the return
feed back to the T1 A input line; the B EXPD setting full
duplexes the return feed back to the T1 B input line; and the
A/B EXPD setting full duplexes the return feed back to the
respective T1 A and T1 B input lines.
When you bypass from an input line to
an expansion line, you must have
another 1061 unit connected to the expand
line. Failure to have a connection will cause
the signal to be interrupted.
