8.141. REDIAL -- Redial the Last Dialed Phone Number

Executing this command causes the Vortex to redial the last number. The last number is defined as all the

8.142. REFASGN -- Assign AEC Reference to Input Channel

This command assigns an AEC reference signal (R1, R2, or EF Bus) to an input channel. Only inputs 1-4 have
echo cancellation, so the command is only valid for those channels. Assigning 1 to an input channel selects
AEC Reference 1 (R1). Assigning 2 to an input channel selects AEC Reference 2 (R2). Assigning 3 to an input
channel selects the EF Bus Reference. The EF Bus reference is an AEC reference that is placed on the EF Bus
by one (and only one) of the linked Vortexes. See the
Bus reference.
Although this command is a channel integer command, the increment and decrement operators (> and <)
are not supported for this particular command.
This command is a channel integer command. See
type of command. The minimum and maximum values for this command are 1 and 3, respectively.
