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

New ALE Features

This section covers the new ALE features that meet the requirements of MIL-STD-188-141B. This includes a description of selective calling features, and operating instructions for the various types of ALE calls. This includes new call types, as well as call types already supported under MIL-STD-188-141A but have been expanded under new version.

Selective Calling

MICOM 2 supports selective calling as standardized in MIL-STD-181-141B and FED-1075, and therefore has the capability and flexibility to link with one or many prearranged or as-needed single or multiple stations.

ALE Addressing Method

ALE uses digital addresses to identify stations. The fundamental address element in the ALE system is the single word: one ALE address word must always contain three characters (one triplet).

A single ALE word is needed for the basic individual station address (this is called a basic address). To increase the available range of addresses, basic addresses can be expanded up to a maximum of 5 words (15 characters): such addresses are called extended addresses.

The characters that can used in addresses are a subset of the standard Basic 38 ASCII character set. This subset includes:

•All the capital (upper case) letters (A to Z)

•All the digits (0 to 9)

•Two utility characters:

!" The stuffing symbol @. It can be used to add characters at the end of an address, so that the resulting length is a whole number of words (triplets). A receiving station then interprets only the non-stuffing characters. For example, if the address has 8 characters, add one @ at the end of the address, whereas for an address with 7 characters, two @ symbols must be added. In special addressing modes, this symbol is interpreted as an ignore instruction: see additional utilization guidelines in Table 1.

!" The wildcard symbol ?. It is used to indicate that any character (except @) is acceptable (this is the equivalent of a don’t mind instruction). See Table 2 for utilization guidelines in the special addressing modes.

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.
