Chapter 1 Introduction ASM-10/8 Installation and Operation Manual
1-8 Functional Description
Remote Power Failure (RPF) Indication
The Remote Power Failure feature notifies the user at a central location of a power
failure in a remote modem.
The remote power failure feature can be configured only when the ASM-10/8
standalone unit (remote) operates in conjunction with the rack-mounted card
ASM-10/8/R (central). When a power failure occurs, ASM-10/8 standalone unit
transmits a special tone, which is detected by ASM-10/8/R and causes the RPF LED
to turn on. A special pushbutton – RPF – located on the front panel of ASM-10/8/R,
allows the user to reset the RPF LED. The RPF jumper in the standalone unit enables
or disables the feature. RPF should be disabled for multipoint applications.
V.54 Diagnostics
ASM-10/8 features V.54 diagnostic capabilities for performing local analog
loopback and local and remote digital loopback. When the modem is set to the
digital loopback mode, the operator at either end of the line can test both
modems and the line. The loopback is controlled either with front-panel
pushbuttons or via pin 18 and pin 21 of the V.24/RS-232 interface.
