NOTE You cannot change the net number at this stage – the bidirectional handshake is always performed on the currently selected net.
OM-E 2072-09689-00 The link is then automatically disconnected when only one station is left (that is, after all the other participants disconnected). The inlink function is available in any type of call that involves the setting up of a link using bidirectional handshaking. Therefore, you can use it in individual calls, group calls, net calls, etc., but not in AllCalls and self calls. NOTE For the inlink function to operate correctly, it must be enabled on all the stations.
OM-E 2072-09689-00 NOTE AMD messages with the GPS position do not enter the stack (the information such message carries is good only at the time you got it): if you do not read the message in time, you can no longer retrieve the message at a later time. Thus, you must allow sufficient time for the destination station to read the position message before when link is disconnected. This is particularly important when Home Acknowledge is enabled: the message will disappear as soon as you disconnect the link.
OM-E 2072-09689-00 2-13. USING THE CCIR MODE The automatic link establishment protocol standardized by CCIR (Consultative Committee on International Radio, currently part of the International Telecommunications Union) is a protocol that provides services similar to the ALE protocol (see para. 2-12), except that it uses a different addressing scheme, based on six-digit station addresses with support for four-digit addresses for backwards compatibility. In the CCIR mode, you can enable the SCAN mode.

OM-E 2072-09689-00 APPENDIX A ALE CAPABILITIES AND FEATURES A-1. SCOPE This Appendix provides a concise description of the ALE capabilities and features. A-2. SCANNING The method used to select the best channel is based on scanning: as long as it is idle, a radio operating in the ALE mode switches frequency at a relatively rapid rate (programmable at 2 or 5 channels per second) within the group of channels that can be used (the ALE frequency table, with up to 100 frequencies).

Network Occupancy Use the chart to determine the best sounding cycle for your particular network, bearing in mind network occupancy, propagation conditions and other considerations.
OM-E 2072-09689-00 A-4. LQA MEMORY The ALE builds a database of connectivity information based on calls and the ALE sounding messages transmitted by other stations in the network. This information is stored in a special LQA memory and is used to determine the link quality of all channels in the networks. The data in the LQA memory is time-weighted, that is, recent information is given more value than old, thus compensating for changing propagation conditions. A-5.
OM-E 2072-09689-00 A-6. SELECTIVE CALLING Micom-Z uses an approach standardized in MIL-STD-181-141B and FED-1075 to selective calling, and therefore has the capability and flexibility to link with one or many prearranged or as-needed single or multiple stations. This selective calling capability is based on the use of a special addressing method. A-6.1 ALE Addressing Method ALE uses digital addresses to identify stations.
OM-E 2072-09689-00 Table A-1. Use of “@” Stuffing Symbol Pattern Interpretation ABC “Standard” 3-character address word, shown here for reference.
OM-E 2072-09689-00 Table A-2. Use of “?” Wildcard Symbol Pattern Interpretation ABC “Standard” 3-character address, shown here for reference. All the characters in this word must be evaluated AB? “Standard” “wild-1” address word. Indicates that only the positions occupied by other characters (“A” and “B”) need be evaluated: the position occupied by the “?” symbol can be ignored (ignored in this context means that any valid character is accepted) A?C ?BC A?? ?B? “Standard” “wild-2” address word.
OM-E 2072-09689-00 The operator can always initiate an outgoing (transmit) AllCall, but the Micom-Z can be programmed to accept or ignore incoming (receive) AllCalls. When a radio issues an AllCall, all the stations that are capable of receiving calls receive the AllCall. In the scan mode, if the Micom-Z station is set to receive AllCalls, it stops scanning when an AllCall is received. If an AllCall channel has been defined, then outgoing AllCalls are performed on that channel.
OM-E 2072-09689-00 A-7. MESSAGES The ALE enables you to create, send or receive alphanumeric messages (“paging” messages) in accordance with the AMD (Automatic Display Message) definition in Federal Standard FS-1045. The messages are displayed on the receiving station LCD display, and can be up to 90 characters long. Messages can be added to any type of call, whether individual, group, net, AllCall, AnyCall, bidirectional handshake, etc.
