MICOM-2ES/2RS/2TS ALE Supplement to Owner’s Guide

Using the MultiNet Feature

Normally, a radio operating in the ALE mode receives and transmits only in its currently selected net. However, there are operational scenarios in which it is beneficial to enable radios to use the ALE functions while still being aware of what is going on in additional nets (for example, firefighters and paramedics must often respond to the same emergency), and be able of answering a call in another net. For this purpose, MICOM 2 radios offer the MultiNet feature.

When the MultiNet feature is enabled, a MICOM 2 radio can operate on multiple nets (up to 20). The operating characteristics then change as follows:

•Channels: each net has a group of assigned (receiving and associated transmitting) frequencies. The radio scans the channels in one net after the other, until all the nets have been scanned.

•Station addresses (the self-address and the net address used when responding to calls): the radio responds according to the self-address assigned to the station in its currently selected net (for a total of up to 20 self-addresses).

•Sounding: each radio sends soundings only within the currently selected net. Each radio scans all the channels in the currently selected net, one by one. Sounding is started 10 minutes after the unit is switched on. The sounding group interval is determined according to the programmed Sounding Auto Time.

During operation, the MICOM radio scans all the frequencies included in the defined nets:

•When the radio receives a call, it responds with the self-address that is programmed in the radio for that net.

•When initiating a call, you select the net you want to transmit to, and then select an address (a specific station, or any other type of address you wish to use). The radio then looks up the frequencies that are associated with the station you call and uses only those frequencies to call that station.

•LQA exchanges and sounding use only frequencies associated with the currently selected net.

Note that the time needed to scan multiple nets may be rather long, even when using the rather fast 5 channels/second scan rate. Moreover, the duration of a call set up request must also be long enough to ensure that your call reaches all the relevant nets. You can use the MaxScanCh parameter (an ALE programming option) to change the duration: the default, when AUTO is selected, is about 7 seconds; however you can select a different value, in the range of 1 to 59 seconds. Make sure to use the minimum value that ensures all the nets will hear your call set up request, because long durations are very disruptive.

MICOM-2ES/2RS/2TS ALE specifications

Motorola MICOM-2ES/2RS/2TS ALE is a sophisticated communication system designed for critical and emergency communication applications. The system is part of Motorola’s esteemed MICOM range, known for its ruggedness and reliability in challenging environments. ALE, or Automatic Link Establishment, is a crucial feature of the MICOM series, enabling efficient and automated establishment of radio links between devices, which is essential for operations where timely communication is a matter of urgency.

One of the main features of the MICOM-2 series is its robust ALE capabilities, allowing operators to automatically find the best frequency for communication based on current conditions. This dynamic frequency selection not only enhances the reliability of the communication link but also minimizes the possibility of interference from other signals, which can be critical in emergency situations.

The MICOM-2ES, 2RS, and 2TS models feature advanced digital signal processing technologies that optimize audio clarity and reception. This ensures that communication remains clear even in noisy environments, which is a pivotal factor in emergency response scenarios. With a digital signal processor onboard, the system is capable of filtering out unwanted noise and enhancing the quality of the transmitted audio.

These models support multiple modes of operation, including both simplex and duplex communications. Such versatility allows users to adapt the system to various communication needs, augmenting its effectiveness in a range of operation scenarios. Furthermore, the MICOM-2 series is compatible with various antenna configurations, enhancing the operational range and flexibility of the system.

User-friendliness is another hallmark of the MICOM-2ES/2RS/2TS ALE systems, as they feature an intuitive user interface that simplifies operation, allowing for quick and efficient communication in high-pressure situations. Emergency responders and military personnel benefit greatly from such ease of use, leading to faster response times and improved overall coordination.

Additionally, the robustness of the Motorola MICOM-2 series ensures that it can withstand extreme environmental conditions. The units are designed to operate in harsh weather and rugged terrains, making them ideal for outdoor usage in emergency or military applications. All these features combined make the Motorola MICOM-2ES/2RS/2TS ALE a reliable choice for organizations that require high-performance communication solutions in demanding conditions.
