3. PART THREE - ADVANCED FEATURES
3.1 NETWORKING
3.1.1 Will you be linking to any other paging terminals using the TNPP networking protocol?
yes
no
3.1.1.1 How many physical connections to other TNPP terminals or satellites are needed?
none
1-2
3-4
5-6
7-8
The Bi-Directional TNPP Network card (950-9346) comes with two serial ports. Each Dual Port Expansion
option (950-9197), equips the Bi-Directional TNPP Network Interface card with two additional serial ports.
This option can expand the Bi-Directional TNPP card to a maximum total of eight serial ports (three
additional Dual Port Expansions). If connection to other TNPP terminals are needed, order a Bi-
Directional card with the appropriate number of Dual Port Expansions.
3.1.2 Will you be an affiliate of a satellite-based paging service?
yes
no
The Unidirectional TNPP Network card (950-9347) equips the 2000 Series paging terminal with a serial
interface to connect with a satellite downlink and receive simplex TNPP transmissions. If a Bi-Directional
TNPP card has already been ordered, then the Uni-Directional card is not needed.
3.1.3 Do you want to extend the coverage of an in-plant paging system by sending pages to one
or more external paging services?
yes
no
The Outdial TAP Card (950-9428) enables the 2000 Series paging terminal to call other paging terminals
over a dial-up telephone line to route pages to them using the TAP protocol.
It is designed to send small
to medium volumes of display pages from one terminal to another where a TNPP interface cannot be
arranged.
It comes with 1 port and a Hayes-compatible modem.
3.2 CALL ROUTING
The PathFinder Call Steering Software allows DID numbers to be routed either to internal paging or voice
mailbox functions, or to external devices.
PathFinder has the capability of offering a “fall-back” to a secondary route if certain conditions are not met
when the first route is tried. The most common application for this is when the call is steered to a mobile
telephone interconnect and the mobile doesn’t answer, then the call is steered to the paging function to
set off the mobile telephone owner’s pager. It is strongly recommended to include Subscriber Recorded
Voice Prompts in this case to make it clear to the caller that the mobile has not answered and that a
message to a pager will be required. Of course, if fall-back to a voice mailbox is desired, then the
PageSaver voice messaging option, with the appropriate prompts and storage options, will be required
(see sections 2.2.3 and 2.3).
In order to route calls from the PSTN (Public Switched Telephone Network, or telco central office) through
the 2000 Series terminal and then back out to the PSTN, a 4-wire E&M circuit must be used to ensure
acceptable audio quality. If such a circuit is not available, the Zetron Model 810 Digital Hybrid can be
used to convert a 2-wire circuit so that it can connect with a 4-wire audio E&M telco interface. See the
Zetron Price List for additional information on the Model 810 Digital Hybrid.
