time Time of Internal Clock
Usage:
time [HH:MM[:SS]
This command displays or sets the time of the radio’s internal real-time
clock. The radio’s real time clock operates from an internal lithium bat-
tery so it is running even if the radio has no DC power connected.
The real time clock is fully compliant with Year 2000 standards.
timeslot Time Slot Assignment
Select which timeslots to transmit. This command has two uses; in
Usage 1, the timeslots can be set or displayed. In Usage 2, all pending
timeslots are committed/made active.
The timeslots may be different at each end of the link. They will be
monotonically mapped; that is, Slot 1 is mapped to Slot 13, Slot 2 is
mapped to Slot 14, etc. To select timeslots 1 through 12, enter the com-
mand
timeslot 1-12.
Usage 1:
timeslot [-d] [slotlist]
Usage 2: timeslot -c
Variables:
–d Disable timeslot(s)
–c Commit pending timeslots
Modifications to the timeslot list are kept pending until all available
slots have been assigned. The user can choose to commit slots when the
last available slot is added to the pending list, or by using the
-c option.
(See Usage 2.)
The default action is to enable given timeslots. If no arguments are
entered, the currently active timeslots and pending timeslots are dis-
played.
If rearrangement of timeslots is desired, some simple rules must be fol-
lowed when CAS framing is used. Refer to the chart below for this dis-
cussion, where “TS” = “Timeslot”:
