TAP

TAP (Telocator Alphanumeric Protocol) was designed as a

one-way protocol to be used by a piece of equipment sending

pages to a single paging terminal, such as an alarm monitoring

system, alphanumeric message entry staon, personal

computer, PC network, or 3rd party email or web-based

paging soware. It typically operates over a serial link either

directly using an RS-232 port, or over a telephone line and

modem.

Dedicated serial TAP ports are available with the Mul-port

Serial Interface opon which comes with 2 to 8 serial ports.

The Dual Telco interface cards also support incoming TAP

applicaons when equipped with alphanumeric messaging

input modem opon. When the call is to a DID phone number

designated for alphanumeric access, the modem automacally

starts trying to communicate using TAP protocol.

OUTDIAL TAP

The Outdial TAP Interface module is designed to send small

to medium volumes of display pages from one terminal to

another. It may be used to extend the coverage region for

some users of an in-plant paging system, by calling up an

external wide area paging service.

Using Outdial TAP, the Series 2000 Paging Terminal can be

congured to automacally forward a page to a public service

provider aer having been congured as a subscriber of that

system.

TNPP

TNPP (Telocator Network Paging Protocol) was designed to e

paging terminals together in a network. A paging terminal that

receives a TNPP packet can tell which pages to transmit, which

ones to pass along to other paging terminals in the network,

and whether any informaon has become corrupted.

TNPP networking is made possible in the Series 2000 terminals

with the TNPP Network Interface Card. The TNPP card can

be congured for unidireconal TNPP to support one-way

satellite downlink, or bidireconal TNPP to support full

duplex, land based networks, and 2-way VSAT satellite based

networks. The TNPP Network Interface Card can support 2 to 8

direct TNPP connecons. Dial-out TNPP is supported with the

oponal TNPP Buer PC soware.

Network desnaons for pages are entered in the subscribers’

database records as simple names instead of the crypc

hexadecimal node idencaon numbers that are used by

the TNPP protocol. The desnaon name is cross-referenced

to the actual node ID number in a lookup table in the

system soware. This means that if a change in the network

conguraon requires a new desnaon node ID, the system

operator can make one change in the lookup table instead of

hundreds or thousands of changes in the subscriber database.

Countdown Paging

Countdown paging allows the operator to sell a set number

of pages to a subscriber. Before the pages are exhausted, a

warning page is sent to the subscriber. This is useful when a

subscriber is behind in payments or to sell pagers prepackaged

with pager service.

Talk-Back

Talk-back allows two-way communicaon between telephone

(land line) callers and mobile radio users. The Series 2000

supports half-duplex and full-duplex radio staons with carrier

switching.

System Voice Prompts

The System Voice Prompts opon uses a factory-recorded

human voice to guide callers through the paging process. The

prompts tell callers when to overdial a pager number, whether

to speak a voice message or to enter a telephone number, and

when an invalid number has been reached. These prompts

can be easily modied by the system operator to t a specic

applicaon. The same high-quality Voice Controller that

records voice pages is used to record/replay system voice

prompts. This opon may be purchased individually or as a

part of the PageSaver opon.

Subscriber Recorded Prompts

The Subscriber Recorded Prompts opon enables users

to record their own voice prompts. The system operator

can specify who has access to this feature, and how long

their voice greengs can be. This opon may be purchased

individually or as a part of the PageSaver opon.

Alarm Monitoring

When equipped with the Alarm Dialer Interface opon, the

Series 2000 paging terminal can accept calls from ADEMCO-

compable alarm dialers using the “ADEMCO 4/9 DTMF” (also

known as “FAST”) protocol. Each alarm dialer can monitor up

to 8 alarm points, and will iniate a display page if any change

is detected by the dialer. In addion, an error page can be sent

if the dialer fails to check in at specied intervals.

TELCO INTERFACE

Telco Line Types

Direct Inward Dial (DID) or E&M input from a telco central

oce is most commonly used by wide-area service providers.

The caller dials a normal telephone number; the last 2 to 7

digits of this number are automacally sent to the paging

terminal by the telephone company, selecng the parcular

subscriber to be paged.

Other types of lines (end-to-end, loop start, ground start, or

E&M e line) are answered with a beep tone and/or voice

prompt. The caller then keys in the pager number using a

touch-tone telephone. In-plant systems oen use these line

types.

Dual Telco Analog Interface Cards

The Dual Telco interface card supports two analog telephone

trunks. Up to 10 Dual cards can be installed in a single Series 2000

system. There are two types of trunk cards. One type handles

telephone company DID lines (either immediate or wink start),

end-to-end, and DTMF overdial line. It also handles PBX lines

(either loop start, E&M type I, ground start, or staon). The

second type of trunk card handles E&M 4-wire audio lines.

Dual Multifrequency Decoder

Most Telco trunks to a customer use Dual-Tone Mul-Frequency

(DTMF) signaling. However, in some instances, Mul-Frequency

(MF) lines may be supplied by the phone company. This opon

supports MF for both trunks on a Dual card.
