2.5.3.3.2 Do you need to support Pulse, DTMF, MFR1, or MFR2 signaling?
Pulse
DTMF
MFR1
MFR2
DTMF (Dual-Tone Multi-Frequency) type phone lines are the most common. However, MFR1 (North
America) or MFR2 (International) signaling may be available in your area from the phone company.
Check with your local phone company to determine which type of phone line you will be getting. The
standard Dual Telco Interface Card accepts DID feed digits by either pulse or DTMF signaling, while
MFR1 (702-9197) and MFR2 (702-9451) are extra cost options.

Each Dual Telco Card can be equipped with a Dual Alpha Input Modem (950-9108) option to allow both of
its two telco trunks to handle modem input from remote alphanumeric entry devices (see section 2.2.2.3).
When equipped with the Dual Alpha Input Modem option, the Dual Telco Card can still process tone,
voice, and numeric pages as usual. Not every trunk need be equipped with alphanumeric modems. Only
those trunks that will be processing calls from alphanumeric entry devices. On a system with only a
couple of alphanumeric applications, such as a few alarm dialers, and a few customers calling up using
alphanumeric entry stations, a single card configured for an end-to-end line equipped with alphanumeric
modems may be sufficient.
2.6 TRANSMITTERS
The following items for consideration cover most transmitter control applications. There are, however, an
almost infinite number of combinations of multiple and remote transmitter control methods. Please call a
Zetron Applications Engineer to discuss your specific application if you have any questions.

Often there is more than one transmitter on each RF channel to extend coverage. However, if the signals
from the various transmitters overlap, interference can result in distorted, lost, or false pages. So zoning
is used to only key up transmitters that don’t interfere. Another use is to offer local paging at one price
and wide area paging at another price. However, often multi-transmitter systems are done via simulcast
which is one zone for all transmitters.

6.4
Do each of your remote transmitters have remote-controllers integrated with them?
yes
no
If a remote transmitter is not equipped with an integrated or outboard device that allows it to decode the
control tones generated at the paging terminal end, it can be equipped to do so with the Zetron Model 66
Transmitter Control Panel (901-9094). The Model 66 decodes Motorola PURC
®
control tones, which are
generated by the Radio Station Card.
