AMIS−49587
MA_DATA_Indication (Tag 50h)
Description: The MA_Data_Indication is sent from the AMIS−49587 (Client or Server) to the base micro to deliver the
received DLC frame to the base micro LLC sub−layer.

See Table 36 Description of the Mac Frame field.
MA_DATA_Indication_Bad_CRC (Tag 53h)
Description: The MA_Data_Indication_Bad_CRC is sent from the AMIS−49587 (Client or Server) to the base micro to
deliver an erroneous received DLC frame to the base micro LLC sub−layer. This command is only used if the Bad CRC
transmitting option is chosen during the configuration (see Sections WriteConfig_Request (Tag 31h) and
WriteConfigNew_Request (Tag 71h))

Table 36 − Description of the Mac Frame field.
Caution: The Mac Frame transmitted with this command is erroneous. It may be used by the base Micro to try and rebuild
a correct frame (by using the repetitions for example), but is cannot be used just as it is.
REPEATER CALL FUNCTION
ISA_REQUEST (TAG 61H)
Description: In client mode, the ISA_Request command is normally sent by the base micro, when it wants to start a special
sequence named « ISACall ». In server mode, the ISA_Request command is normally sent by the base micro, when it has
received a MA_Data_Indication corresponding with an ISACall indication. The ISA_Request command is sent from the base
micro local LLC sub−layer to the AMIS−49587 local MAC sublayer to switch the AMIS−49587 in special mode called «
ISACall ». This service is an internal service and should not be used. Without correct handling at the system level it can disable
the communication.
