3.2 Operating ASM-60

Turning On ASM-60

ASM-60 is turned on as soon as the power is connected to the unit. The PWR indicator lights up and remains lit as long as ASM-60 receives power.

Normal Operation

Always operate ASM-60 in pairs: ASM-60/CO opposite ASM-60/CPE.

ASM-60 requires no operator attention once installed, with the exception of occasional monitoring of front panel indicators. Intervention is only required when ASM-60 must be adapted to new operational requirements.

Normal Indications

Table 3-2shows the status of the ASM-60 indicators, a few seconds after power-up.

	Table 3-2. ASM-60 Indicator Status
Indicator	Status
PWR	ON
TD	Depends on DTE data transmission
RD	Depends on DTE data transmission
RTS	Depends on DTE RTS signal status
DCD	Depends on remote modem data transmission
TST	OFF
ALM	OFF

SYNC A/SYNC B Green or red, depending on remote modem data transmission

If the above LED indications are not obtained following initial power turn-on, refer to Chapter 5 for the diagnostic test instructions.

Turning Off ASM-60

To turn off ASM-60, remove the power cord from the power source.
