ETP-GSM – Cellular Interface
Remote-mounting Omni-directional Antenna
Antenna Mount with Cable Assembly
IMPORTANT NOTE: The ETP-GSM Cellular Interface does not comply with Enhanced 911 (E911)
requirements mandated by the Federal Communications Commission (FCC). In order to comply
with the E911 mandate, the ETP-GSM Cellular Interface software prohibits the dialing of 911.
IMPORTANT NOTE: Programming of the ETP-400 Series Phones cannot be done through a
remote call to the ETP-GSM Cellular Interface. For programming, an ETP-400 Series Phone must
be connected directly to a standard analog phone line connection.
IMPORTANT NOTE: The built-in auto-dialer of the ETP-400 Series Phone cannot dial a secondary
number in round robin fashion when used in conjunction with the ETP-GSM Cellular Interface.
IMPORTANT NOTE: All programming, diagnostics, and identification of the ETP-400 Series
Phones are accomplished through the transmitting and receiving of DTMF signals. Cellular
transmissions and cellular networks may interfere with and distort these tones. As a result of these
irregularities, model ETP-TAL Talk-A-Lert Polling may not function as intended and, therefore, may
not be appropriate in that application or environment; ETP-TAL Talk-A-Lert Base Station will not
function at all.
In any event, due to these irregularities, programming of the ETP-400 Series Phone should be done
on a land line (i.e., not through the ETP-GSM Cellular Interface.
