TSAM Installation and Maintenance Rev. 2.10 CTI Products, Inc. 1. Chapter 1 System Description System Description Transmitter steering radio systems consist of multiple strategically located transmitters and receivers. When a mobile or portable calls the dispatcher, the system comparator selects the receiver with the best signal. The CTI Transmitter Steering Audio Matrix (TSAM) monitors this information to determine the best site for the next transmission.
TSAM Installation and Maintenance Rev. 2.10 CTI Products, Inc. 1.2 Chapter 1 System Description • A transmitter may be manually selected via a "force" override. • Optional Secondary Mode operation, which removes a single base station site from the voting scheme and locks it on an alternate frequency, using internally generated frequency select tones. Audio is automatically routed to a secondary base station interface. • Two tone generators, one for main and one for secondary mode operation.
TSAM Installation and Maintenance Rev. 2.10 CTI Products, Inc. 1.4 Chapter 1 System Description Feature Breakdown The "xxx" in the model number indicates the version number of the unit.
TSAM Installation and Maintenance Rev. 2.10 CTI Products, Inc. 1.5 Chapter 1 System Description TSAM Audio Switching Transmit Audio from the radio control console microphone enters the TSAM through the Console 1 (Main--Steered Channel) and Console 2 (Secondary Channel) audio line inputs. A PTT signal for both Console 1 and 2 is also connected to the TSAM. When an operator keys the Main channel, transmit audio from the console is routed through the TSAM to the steered transmitter line output.
TSAM Installation and Maintenance Rev. 2.10 CTI Products, Inc. 2. Chapter 2 Main Channel Operation Main Channel Operation The Main radio channel is the steered radio channel. The TSAM has inputs to monitor the receiver Vote or Select lines from the radio system comparator. The Vote indications are processed to determine the start and end of transmissions from field radios.
TSAM Installation and Maintenance Rev. 2.10 CTI Products, Inc. 2.2.1 Chapter 2 Main Channel Operation Instant Update Mode Instant Update Mode updates the steered transmitter as soon as the Free-vote timer has expired at the beginning of a portable/mobile transmission. It is used only with the First Receiver Vote option enabled. This mode mode is cannot be used with the Smart-Steer™ voting algorithm.
TSAM Installation and Maintenance Rev. 2.10 CTI Products, Inc. Chapter 2 Main Channel Operation Since the Smart-Steer algorithm does not complete vote processing until the end of current receiver activity, it must use the End of Receive Update Mode. 2.2.3 Instant Update Input This input can be used to switch between End of Receive Update Mode and Instant Update Mode from the console. To do this, program the TSAM for End of Receive Update Mode.
TSAM Installation and Maintenance Rev. 2.10 CTI Products, Inc. 2.3 Chapter 2 Main Channel Operation Initial Transmitter Selection Options If you have made it this far in the manual, you're probably saying, "Okay, I understand how the Instant Update and End of Receive Update Modes work, but what happens after the system has been quiet for a while? Which transmitter is used?" (At least I thought I heard you say that.
TSAM Installation and Maintenance Rev. 2.10 CTI Products, Inc. Chapter 2 Main Channel Operation range is interpreted as off and will display as revert off on the screen. Numbers outside the range of 5 to 65535 will produce an out of range error, and you will be prompted again to enter a value in the correct range. 2.3.2 Dynamic Update Mode (TSAM Version 1.20 and up) Dynamic update mode is used in conjunction with the EOR (End of Receive Update Mode) and Integrated Vote mode.
TSAM Installation and Maintenance Rev. 2.10 CTI Products, Inc. 2.4 Chapter 2 Main Channel Operation Simplex Operation In simplex systems, the voting receivers will hear the base station transmitters. If the comparator is active during this time, the TSAM must be instructed to ignore any voting activity. This is done by programming the ‘ Sense RX activity during Console 1 PTT’ option is set to ‘ N’ This is found under the TX Steering menu.
TSAM Installation and Maintenance Rev. 2.10 CTI Products, Inc. 2.5.1 Chapter 2 Main Channel Operation Repeater Operation with various Steering Algorithms The steering update mode used determines how repeater keying takes place in the TSAM. The TSAM uses Instant and End of Receive Update modes. The Smart-Steer algorithm always uses the EOR update mode. First RX steering uses either Instant update or EOR update modes. Repeater keying in each of these modes is described in the following sections. 2.5.1.
TSAM Installation and Maintenance Rev. 2.10 CTI Products, Inc. 2.5.2.2 Chapter 2 Main Channel Operation Repeater Hang Time with EOR Update Mode For EOR updated modes, the TSAM steers to the proper site for the next transmission when the current transmission ends. If no site change occurs, the current site remains keyed for the duration of hang time. If a site change does occur, the current site is unkeyed and the new site is keyed. It remains keyed for the duration of hang time.
TSAM Installation and Maintenance Rev. 2.10 CTI Products, Inc. 2.5.6 Chapter 2 Main Channel Operation Console Priority with Repeater Systems In a typical transmitter steering repeater system, a transmitter is keyed from two different sources. Detection of a received signal will key a transmitter so it can be "repeated", and the systems dispatcher will key the transmitter from the dispatch console. In many systems, it is required for the dispatcher to have priority access to the steered transmitter.
TSAM Installation and Maintenance Rev. 2.10 CTI Products, Inc. 2.6 Chapter 2 Main Channel Operation Multicast Options Unit Versions 1.70 and up / Units with Secondary System Capability Only The Multicast feature allows the dispatcher to key a number of transmitters simultaneously on the main channel for system-wide announcements. When the latched Multicast input is active and the console is keyed, the Transmitter Steering System keys all transmitters that are programmed for Multicast operation.
TSAM Installation and Maintenance Rev. 2.10 CTI Products, Inc. 3. Chapter 3 Secondary Channel Operation Secondary Channel Operation Only available on TSAM units with Secondary Option One unique feature of the TSAM is that it allows a properly equipped steered base station (receiver/transmitter pair) to be removed from the transmitter steering system and operate as an independent base/repeater on a second channel. The secondary TSAM channel looks like and additional channel to the system console.
TSAM Installation and Maintenance Rev. 2.10 CTI Products, Inc. 3.1 Chapter 3 Secondary Channel Operation Secondary Site Selection The TSAM automatically completes the following steps when a dispatcher selects a secondary site. Secondary Operation is initiated when the TSAM detects a non-zero secondary site on the binary active low Site Select inputs. If the site is currently voted, the receiver is immediately disabled, forcing the receive comparator to re-vote.
TSAM Installation and Maintenance Rev. 2.10 CTI Products, Inc. 3.2 3.3 Chapter 3 Secondary Channel Operation Secondary Site Select "Off" 1. This function terminates secondary operation and returns the secondary base to the Main steered channel. 2. Secondary Operation is terminated when all secondary select inputs return high (active low inputs). 3. The TSAM mutes C2 RX Audio. 4. The TSAM sends the F1 frequency change tone sequence to the secondary base. 5.
TSAM Installation and Maintenance Rev. 2.10 CTI Products, Inc. 3.4.1 Chapter 3 Secondary Channel Operation Momentary PL Monitor Control When the Monitor input is momentarily activated, the TSAM sends a PL Monitor tone out the selected Secondary site. The station re-enables the PL decoder on the next transmission. 3.4.2 Sustained PL Monitor Control When the Monitor input is activated, the TSAM sends a PL Monitor tone out the selected Secondary site.
