break the connection. He may use the Monitor Function command to listen to the conversation
between the two HF radio users, and enter the “Disconnect Other Extensions” command to
terminate the link when the conversation is complete.
3.5.1.2 HSP-2A Keypad – Break a Connection
To disconnect the HSP-2A from any connection, enter the disconnect command * # (star –
pound). If the HSP-2A is currently engaged in a conference call between the HSP-2A, the
VHF radio at extension 5 and a PSTN subscriber using the PSTN-2 at extension 8, the * #
sequence entered at the HSP-2A keypad will remove the HSP-2A from the call, but leave the
VHF radio user and the PSTN subscriber connected.
3.5.1.3 HSP-2A Keypad – Attention Command
When the Attention Command, * * *, is entered through the HSP-2A, a voice prompt will be
returned identifying the extension number of the HSP-2A module receiving the command. In
most systems, this will result in the voice prompt “EXTENSION 00”. The Attention
Command can be given whether or not the HSP-2A module is currently connected to another
module. This allows quick system operation verification without having to make a connection.
3.5.1.4 HSP-2A Keypad – Report Connections
Whenever the Report Command, * 3 0, is entered at the HSP-2A keypad, the ACU will list all
existing connections. They can be heard at the front panel speaker or the HSP-2A handset.
This command cannot be made via any of the interface modules; it’s valid only when entered
by the HSP-2A keypad.
3.5.1.5 HSP-2A Keypad – Disconnect Another Extension
This command allows the local operator to use the HSP-2A keypad to select any system
module and remove that extension from any cross-connections that it’s currently participating
in. When the operational command * 3 3 nn, is entered, extension nn immediately removed
from all existing cross-connections. Note that this command cannot be made via any of the
interface modules; it’s valid only when entered by the HSP-2A keypad.
3.5.1.6 HSP-2A Keypad – Monitor Function
This command enables the HSP-2A to monitor the receive audio being sent to any other
module or group of modules. Enter * 3 4 n, where n is the extension to be monitored. To
discontinue monitoring, re-enter * 3 4 n, where n is the extension currently being monitored.
This command toggles the selected module, first turning the module function on, and then
cutting it off. When the monitor function is enabled, the local HSP-2A operator will only hear
the receive audio of the module being monitored; the Monitor Function does not give the HSP-
2A operator any control over the monitored module, and it will not receive any audio from the
HSP-2A handset. The monitoring module will still be capable of making connections and
perform other functions if desired. The voice prompts; “MONITORING XX” and “XX
DISCONNECTING,” inform the user of the monitoring module (initiator) of the operational
changes made.
