The ASTRO Tone Remote Control Board also provides an RS232 port through
which the Consolette communicates with an ASTRO Console Interface
Module (ACIM) using the Smart Modem Protocol (SMP).
NOTE: For correct operation, the ACIM must be connected to a Gold
Series Console programmed with System 3.0 Conventional
or later.
Depending on the setting of S100-3, the operation of the Tone Remote Control
board can vary as follows:
In this setup, the Consolette can only be controlled remotely by a tone remote
deskset, via the wireline, as described in "General Description" on page 23
under "Tone Remote Control Board." The Consolette will report both PTT-IDs
and Call Alert IDs, when applicable, to Accessory Connector 1 (J13). See
Table 13. For a list of supported IDs, see Table 14 on page 31.
