(1) Enter *92 then depress the Enter key. (Port 1 is *91, port 3 is *93, and port 4
is *94.)
(2) Enter number 600000 then depress the Enter key to clear any AAA99 IR
codes.
(3) Enter the configuration code *5 60 then depress the Enter key. The TD-1271
transmits the configuration of the port to the channel controller. This is observed by the
ACCPT, XMT, and ACK lamps on the front panel of the TD-1271.
(4) Enter the guard number into the port—*1 15014—then depress the Enter
key. A momentary 01 is displayed if that is the only guard in the multiplexer port. If
more than one guard is in the port a 02 or higher number is displayed. The preference is
to have only one guard in each port and that the same guard number is not put into any
other port. To read what guards are entered in the port, depress number 2 and watch
the display. A number is displayed for two seconds, which is the TBA of the port (for
example, 02157). Each guard number in the port is displayed for two seconds. To
remove unwanted guard numbers use the command number 4 followed by the guard
number then depress the Enter key (for example, number 4 15008 ENTER).
(5) Use the keystrokes—#76 15014 ENTER—to request a connection to the
appropriate guard. The ACCPT, XMT, and ACK lamps on the front panel of the TD-
1271 cycle. If the guard number is a valid guard for the channel, the proper
configuration code was entered, and the terminal is an authorized user on the channel.
The channel controller responds with a guard connect command. (If one of the previous
actions is not valid, an information code is returned.) There is a laminated sheet with
the codes and their meanings). If everything is correct, the port connects to the correct
time-slot (guard) and beeps five times to indicate a connection. The CALL CONN lamp
should illuminate.
(6) Enter *7 to display the guard number the terminal connected to.
(7) Enter *6 to exit the port.
(8) Repeat above steps for other circuits/baseband equipment configurations.
h. When a connection is no longer required or desired—
(1) Enter the appropriate port with a *91, *92, *93, or *94 command.
(2) Enter—*4 ##### Enter–to remove the guard number (for example, *4 15014
ENTER).
(3) Enter number 4 to disconnect from the circuit.
(4) Enter *6 to exit the port.
Notes: Be observant of KGV-11 keymat rollover dates and memory locations.
They are listed in the Daily Comm Status messages. If mux front panel
PREC display goes to a B, it is an indication of improper key or memory
location.
Do not put the same guard number in two or more ports.
If the TD-1271 beeps entering a guard connect request (for example,
number 76 #####) and refuses to take the guard, it indicates the port is
keyed already. The source of the key must be removed before the TD-
