3.5.1.10 HSP-2A Keypad – System Reset Feature
The System Reset Feature allows the local operator to reset the ACU-1000 to its initial power-
up state. This means all current connections will be lost, and the unit will return to any
connections stored last by the * 3 6 command. In order to prevent any inadvertent or
unauthorized use of this powerful feature, the System Reset Feature can only be used after first
being enabled at the HSP-2A keypad. In addition, a “system reset code” is entered, and DSP-2
or PSTN-2 users must then enter this code in order to implement this feature.
The ACU-1000 factory default for this feature is disabled. To enable System Reset capability,
enter * 9 0 n n, where “nn” is any pair of digits other than 00. The feature is now enabled, and
“nn” is the system reset code. If a DSP-2, RDI-1, or PSTN-2 user (who is currently connected
to the system) enters the DTMF command * 9 0 n n, the system will be reset. If * 9 0 and any
digits other than the system reset code are entered, the system will not be reset.
To disable this feature, enter * 9 0 0 0 at the HSP-2A keypad. To re-enable, once again enter *
9 0 n n , where “nn” can be either the previous system reset code or an entirely new code.
3.6 Operation Via Remote DTMF
An ACU-1000 may be controlled via DTMF from the field. This may be from the DTMF
keypads of radios or other 4-wire devices, remote telephones connected via PSTN, or local
telephone sets interfaced to an LP-2 module. Operation is similar to what can be done by a
local operator via the HSP-2A keypad, though the command set is more limited.
Operation via DTMF may take place in conjunction with operation via the ACU Controller or
the WAIS Controller. When connections are made or broken by DTMF, the changes are
reported to any control programs by the ACU-1000 and show up immediately.
Note that a module must have DTMF enabled or it will ignore DTMF input. It may also have
PIN Security enabled. If so, DTMF will be ignored unless the proper PIN is entered.
