3.5.1.1 HSP-2A Keypad – Make a Connection
When the command * n n is entered at the HSP-2A keypad, a connection is made between the
local operator at the HSP-2A and the communications medium at extension n n. For example,
if a VHF radio is wired to a DSP-2 module installed at extension #5, the command * 0 5 will
connect the local operator to the VHF radio. The local operator will hear the distant radio
user’s transmit audio via the radio attached to the DSP-2 module. When the PTT switch on the
HSP-2A handset is depressed, the local operator’s speech will be transmitted to the radio user.
If a PSTN module is installed at extension #8, the command * 0 8 will connect the local
operator to the telephone line wired to that PSTN module. Voice prompts guide the local
operator at the HSP-2A to enter the telephone number to be dialed, and provide other useful
information, such as informing the user if a module is busy or otherwise unavailable. To make
a conference call among several modules, add a second connection after the first is made. For
example, to make a conference call between the local operator at the HSP-2A, the VHF radio at
extension 05, and to a PSTN subscriber via the PSTN module at extension 08, first connect to
the VHF radio as described above, then at any time add the PSTN subscriber by entering * 0 8
and following the voice prompt instructions provided.
To make a connection between a pair of modules, neither of which is the HSP-2A, the local
operator must first make a connection between the HSP-2A and one of these other modules,
then create a conference call with the remaining module, and finally enter the disconnect
command * # to remove the HSP-2A from the call. If for some reason the two modules still
engaged in the link can not break the connection themselves (for instance, if both are HF radios
so neither can reliably transmit DTMF commands), the local operator must use the HSP-2A to
