Name Type Function
DIG Pushbutton The digital loopback pushbutton causes the local ASM-10/8 to
loop received data to its transmitter (see Figure 4-3).
ANA Pushbutton The local loopback (V.54 loop 3) pushbutton causes the local
ASM-10/8 to loop its transmitter output back to its receiver
(see Figure 4-1). This loopback may also be activated from the DTE
when the PIN 18 jumper is set to EN.
REM Pushbutton The remote digital loopback (V.54 Loop 2) pushbutton causes the
remote ASM-10/8 to loop received data to its transmitter
(see Figure 4-2). This loopback may be also activated from the
terminal when the PIN 21 jumper is set to EN.
The PIN 18 and PIN 21 jumpers control the LLB and RLB activation only from the
DTE interface. The jumper settings do not affect the ANA and REM pushbutton
operation.
3.2 Operating ASM-10/8
Turning On ASM-10/8
ASM-10/8 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-10/8 receives power.
ASM-10/8 requires no operator attention once installed, with the exception of
occasional monitoring of front panel indicators. Intervention is only required when
the modem must be configured to new operational requirements, or the diagnostic
tests must be performed.
