DeSynchro_request(0x11)

Figure 38. Sequence Diagram for DeSynchro_Request

The Desynchro_Request command is used by the external controller to enforce the not synchronized state in the

AMIS−49587 and therefore it starts looking for a new synchronization.

Frame Format:

<STX> 0x03 (Length) 0x11 (Desynchro_Request) CHK

7.4.13 AccessDB_Request

Field Name Ident Description

PhyAlarmRequest 000F Request the transmission of a Phy Alarm

7.4.13.1 PhyAlarmRequest

Description:

This request is used to send a physical alarm pattern. No data is transmitted to indicate the number of repetitions, the

AMIS−49587 already knows this number because it is in its set of configuration data.

Request Format:

<STX> 0x05(Length) 0x41 (AccessDB_Request) 0x0F00 CHK

Confirm Format:

<STX> 0x06(Length) 0x42 (AccessDB_Confirm) 0F00h Number of alarm Transmissions (1 byte) CHK

7.4.14 AccessDB_Confirm

See paragraph AccessDB_Confirm.

7.4.15 AccessDB_Error

*An unsolicited message is a message that is originating from the AMIS−49587, based upon an AMIS−49587 internal event. The message is

not provoked by a prior command sent by the external processor.

7.5.1 AccessDB_Request

The AccessDB_Request command can be used to read data path statistical information from the AMIS−49587.

Like in all other AccessDB_Request commands, the specific identifier of the data that is to be read needs to be provided:

Field Name Identifier Description

Invalid−frame−counter 0x0006 Read the value of the invalid−frame counter and then set to 0

Counters 0x000D Read the value of the data counters:Counter Crc Ok, Counter Crc Not Ok,

Repeater counter, Transmit counter, corrected frames counter, and then

set to 0 or not

DataStats 0x0010 Read the value of the Data statistics, and then set to 0 or not.

7.5.1.1 Invalid Frame Counter

This request is used to read the Invalid Frame Counter of the AMIS−49587. Once the request sent to the AMIS−49587, the

Invalid Frame counter is automatically set to 0. The AMIS−49587 answers with the value of the Invalid Frame Counter

Request Format:

<STX> 0x05(Length) 0x41 (AccessDB_Request) 0x0600 CHK

Confirm Format:

<STX> 0x06(Length) 0x42 (AccessDB_Confirm) 0x0600 Invalid Frame Counter (1 byte) CHK

7.5.1.2 Data Counters

The Data Counters request is used to read the value of the data counters in the AMIS−49587. It contains one byte which is

used to know whether the counters must be reset or not (00: no reset, 01: reset) after reading them out.

There are 6 counters coded on 4 bytes each, which indicates:

1. number of CRC OK frames received

2. number of CRC not OK frames received

3. number of repeated frames

4. number of transmitted frames

5. number of corrected frames (with option Pad Correcting)

6. number of frames with bad Frame Indicator received

Request Format:

<STX> 0x06(Length) 0x41 (AccessDB_Request) 0x0D00 Request Counters (1 byte) CHK

Confirm Format:

<STX> 0x1D(Length) 0x42 (AccessDB_Confirm) 0x0D00 CRC_OK (4 bytes), CRC_NOK (4 bytes),

Rep_Frames (4 bytes), Tr_Frames (4 bytes),

Corr_Frames (4 bytes), FI_NOK (4 bytes)

CHK

7.5.1.3 DataStats

The DataStats request is used to read the value of the current data statistics in the AMIS−49587. The request contains one

byte which is used to know whether the counters must be reset or not (00: no reset, 01: reset) after reading them out.

If the AMIS−49587 is synchronized the counters consist of 30 bytes:

1. The value of signal and noise (S0, N0, S1, N1) for the last subframe received (4 * 2 bytes) + the method and gain

used to demodulate this subframe (2 * 1 byte)

2. The method, gain and SNR (S0/N0, S1/N1) on the 5 last time slots in reception mode (5 * 4 bytes) + 1 byte to know

the actual position in the table

If the AMIS−49587 is not synchronized the counters consist of 36 bytes:

1. The values of the real and imaginary parts of the signal for each frequency (I0, Q0, I1, Q1),

2. for the 4 last calculated time−slots (4 * (4 * 2 bytes) )

3. The current position in the board (1 byte)

4. The software reception gain (1 byte)

5. The hardware reception gain (1 byte)

6. The R_ALC value (1 byte)

Request Format:

<STX> 0x06(Length) 0x41 (AccessDB_Request) 0x1000 Reset Counters (1 byte) CHK

Confirm Format:

If the AMIS−49587 is synchronized:

<STX> 0x23(Length) 0x42 (AccessDB_Confirm) 0x1000 Signal_noise_subframe (10 bytes),

SNRreception (20 bytes)

CHK

If the AMIS−49587 is not synchronized:

<STX> 0x29(Length) 0x42 (AccessDB_Confirm) 0x1000 I0,I1,Q1 (32 bytes), Pos (1 byte), GainSoft

(1 byte), GainHard (1 byte), R_ALC (1 byte)
