I INTRODUCTION
Congratulations on your purchase of the Model 748 Repeater Manager / Teleconnect, the latest,
most powerful shared customer interconnect available from Zetron, Inc. It is designed for service
providers who need the utmost in performance in order to compete effectively with cellular
telephone systems, trunking operations and other threats to conventional mobile telephone
service.
The Model 748 may be equipped with previously unavailable capabilities, such as owner
recorded voice prompts, interconnect hog mode and Wild ANI for inter-system roaming. These
and other features ensure continued profitability and competitiveness for providers of
conventional interconnect service.
In addition to its usefulness to service providers, the Model 748 is also ideal for private,
customer-owned systems that need a high degree of versatility and numerous convenience
features.
For ease of configuration the Model 748 is available in three versions: Basic, Selcall and
Roamer.
As a telephone interconnect, the Model 748 provides individualized telephone service for either
99 (Basic or Selcall) or 750 (Roamer) different customers (DTMF ANI users). The telephone
interconnect provides all of the features of a multi-user interconnect plus the ability to add
CTCSS/DCS encoding and decoding per user. The Model 748 provides the complete interface
between a transmitter, receiver and telephone line.
As a repeater panel, the Model 748 supports encoding and decoding of all 50 CTCSS tones and
104 DCS codes for dispatch. It also includes airtime tracking of all tones/codes, a Morse ID for
each tone/code, and Zetron's unique hog mode timers to prevent “airtime hogs” from
monopolizing the channel.
The Selcall version adds selective calling capabilities to the Basic Model 748. This allows each
mobile or handheld to be individually called by the telephone party or another mobile. Included
formats: DTMF, DTMF-t, Two-tone and Five-tone. The Roamer version increases the ANI
capacity from 99 to 750 plus adds Wild ANI to the Selcall version.
Accounting information is accumulated by the Model 748 for later review or billing purposes.
The airtime used by each customer is tracked in an “Hours:Minutes:Seconds” format. Airtime
can be either accumulated (count up) or pre-pay (count down). Optional call detail information,
or SMDR (Station Message Detail Record) data, may be printed and stored in the Model 748.
Call detail includes; date, time, mobile ID number, telephone number or mobile number dialed,
call length, call completion status and originating mobile's ANI.
The Model 748 may be remotely controlled and programmed over the telephone, via the internal
modem, or locally with a computer running terminal emulation software, or an ANSI compatible
terminal. Local programming can be done without taking the Model 748 off line or out of
service. Installation (signal levels and adjustments) and turning users ON/OFF can be done using
DTMF commands from the phone or over the air.
