5.5.2 Edit Line Card
Due to the increasing number of formats a single line can accept and the wide variety of
manufacturer’s specifications for handshake/acknowledgment tones required for their digital
dialers to communicate, Silent Knight strongly recommends the following for handshake tone
order.
1. Some SIA DCS communicators respond to the 2300Hz handshake. Always place the
2225Hz handshake tone first for line cards accepting SIA DCS format.
2. Some Contact ID communicators respond to the 1400Hz handshake followed by the
2300Hz handshake instead of the dual tone 1400-2300Hz handshake (NAPCO Gemini
communicators have been known to do this). Line cards accepting Contact ID should not
have the 1400Hz followed by the 2300Hz before the dual tone 1400-2300Hz handshake.
3. SIA DCS communicators will respond to the Modem II and IIe handshakes. If a line card
is to accept both SIA DCS and Modem II or IIe, the 2225Hz handshake must come before
the Modem II and Modem IIe handshakes.
4. Some Westec panels will respond to the Modem II handshake. If a line card is to accept
both Westec and Modem II formats, the Westec handshake must come before the Modem
II handshake.
5. Some ITI panels don't respond to the default 2225Hz handshake. They need a lot longer
handshake duration than what the 9500 receiver is defaulted as. You don't want to change
the default 2225Hz handshake (1st handshake group) because it's optimized for SIA pan-
els. What you should do is to program the 2nd 2225Hz handshake group with a long hand-
shake duration (say 2550 ms). This way, a SIA panel responds to the 1st 2225Hz
handshake and ITI panels respond to the 2nd 2225Hz handshake.
