1.3 TRULINK 

DESCRIPTION 

TruLink is a versatile wireless system in that it operates in various situations and environments.  In 
scenarios where portable intercom functionality is needed, only TruLink Portable Transceivers 
(TPTs) are required. 

The TruLink system is a fully duplex system that permits multiple users to speak simultaneously. 
Unlike conventional walkie-talkies, TruLink users can converse among themselves without pressing 
a Push to Talk button or waiting for another user to finish their transmission.  

The system supports 50 channels (0-49). Depending on the system configuration, up to 31 users can 
be logged on to a channel. Each channel is an independent network. A TruLink network is composed 
of one TruLink unit designated as the master and all other TruLink units operating as slaves. 

The TruLink Support Station (TSS) is also available with the ability to charge commercially 
available NiMH batteries while still in a TPT unit, display built-in test (BIT) results, and set the 
channel on up to six TPTs at a time. 

Table 1.6-1 provides a list of the TruLink equipment and part numbers, embedded within the TPT, 
TAP and DTP part number is a specified configuration which is factory loaded in the unit, i.e., 780-
1000-001-CF00xx-Mx, where the CF00xx-Mx is configuration specific. Please see specific 
configuration addendums for details on the individual configurations. 

A picture of each of the units in the TruLink system is shown in Figure 1.6-1. 

1.4 NETWORK 

CONFIGURATION 

A TruLink network is composed of one master unit and a group of slave units. The master unit is the 
central point of the TruLink network. All slave-to-slave communications are routed through the 
master. When a network includes a TAP or a DPT, it is typically designated the network master. 
However, any TPT can be set to be the master. 

1.5 CAPABILITIES 

TruLink uses a modulation technique, Frequency Hop Spread Spectrum (FHSS), which provides 
security improvements for Low Probability Intercept (LPI) and Low Probability Detection (LPD), 
over conventional narrow-band radios that are susceptible to intercept by low-tech scanners.  The 
technique also provides some resistance to interference caused by undesired signals and multipath. 

TruLink’s rugged construction is built to withstand extreme environments of: temperatures, sand, 
dust and moisture. Rugged environments also involve high noise and poor RF conditions. TruLink 
uses advanced Digital Signal Processing (DSP) technology to mitigate these effects.
