Chapter 3 Operation Installation and Operation Manual
3-2 Operating Procedure ASM-40 Ver. 1.0
Table 3-1. ASM-40 Front Panel Controls and Indicators (Cont.)
Name Type Function
DIG Pushbutton The digital loopback pushbutton causes the local ASM-40 to loop
received data to its transmitter. Data Set Ready changes to OFF
(see
Figure 4-3
).
ANA Pushbutton The local loopback (V.54 loop 3) pushbutton causes the local
ASM-40 to loop its transmitter output back to its receiver
(see
Figure 4-1
). The transmitter continues to send data to the
line. This loopback may also be activated from the DTE when the
ALBE section of the SW3 switch is set to ON.
REM Pushbutton The remote digital loopback (V.54 Loop 2) pushbutton causes the
remote ASM-40 to loop received data to its transmitter
(see
Figure 4-2
). Data Set Ready changes to OFF. This loopback
may also be activated from the DTE when the RLBE section of the
SW3 switch is set to ON.
PATT Pushbutton The PATT switch causes ASM-40 to send and receive a 511 test
pattern. If errors are encountered, the ERR indicator lights up.
Receive Data and Clear To Send changes to OFF. The RD LED turns
off.
3.2 Operating Procedure
Turning ASM-40 On
ASM-40 is turned on as soon as power is connected. When power is connected,
the PWR indicator lights up and remains lit as long as ASM-40 receives power.
ASM-40 requires no operator attention once installed, with the exception of
occasional monitoring of front panel indicators. Intervention is only required
when:
ASM-40 must be adapted to new operational requirements
Diagnostic loopbacks are performed.
