New ALE Features

AnyCalls

An AnyCall is a general broadcast similar to AllCall with the difference that it requests responses, without designating any specific addressee(s). Therefore, an ALE station may use the AnyCall to generate responses from essentially unspecified stations, and thus it can identify new stations and connectivities.

The global AnyCall address is @@?. As a variation, the calling station can also use selective AnyCall, which is identical in function to the global AnyCall, except that it specifies the last single character of the addresses of the desired subset of receiving stations (that is, it replaces the ? with an alphanumeric – see more details in Table 1). If even narrower acceptance and response criteria are required, double selective AnyCall may be used: this is identical to selective AnyCall, except that its special address (@AB) specifies the last two characters that the desired subset of receiving stations.

The operator can always initiate an outgoing (transmit) AnyCall, but the MICOM 2 can be programmed to accept or ignore incoming (receive) AnyCalls.

Any station accepting an AnyCall stops scanning, and then initiates a response in a randomly selected timeslot.

Self Addresses

Stations can also use their own self addresses when making calls. This may be useful for self-test and maintenance purposes, etc.

The self address may be used only in specifically-addressed calls including a group call, but not in an AllCall or AnyCall.

Null Address

The null address is a special type of address that is not directed to, accepted by, or responded to by any station.

This address is intended for test and maintenance purposes, and to provide buffer time: for example, if a null address appears in a group call, no station will respond in the associated timeslot.

Inlink Address

The inlink address, ?@?, is used to instruct all the stations participating in an already established link to accept and act upon the information sent with the inlink address. For example, any station can use the inlink address to send an AMD message that all the linked stations would present to their user.

The inlink address is recognized only after a link is established between two or more stations.

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.
