Appendix A Protocol Configuration Using Discrete Messages
A.2
Monitoring Configuration Using Individual Messages
To configure the board for monitoring it using individual messages, proceed as follows:
1. Build and send an
SSD Reset Request
to the SSD module. This contains the parameters to initialize the
SSD module.
2. Build and send a
Board Reset Request
for each board in the system. This message contains the address
(or identifier) of the board and the name of the codefile. It causes the board to be reset and the codefile
downloaded. For each board, the application should wait until a
Board Status Indication
is received and
inspect the status field to determine if the reset operation was successful. On failure, the user should
check carefully the parameters and try again. On success, the user should continue with the next step.
3. Build and send a
Board Configuration Request
(
MGT_MSG_CONFIG0
) to the onboard management task
(
MGMT_TASK_ID
) to configure the basic board parameters. When using DSI SS7MD Boards, the value of
the
config_type
parameter in the
Board Configuration Request
must be set to 3. For this version of the
message, the automatic configuration of MTP parameters is not supported. Wait for the confirmation
message and check the status.
4. To set up the LIU and port for the T1/E1 ports, the
LIU Configuration Request
(
LIU_MSG_CONFIG
) should
be used. For monitoring, the
high_Z
parameter must be set to 2. Wait for the confirmation message for
each LIU and check the status.
For each link in the system:
5. Build and send a
Layer 1 Configuration Request
(
MGT_MSG_L1_CONFIG
) to set up the physical
configuration parameters for the link. This message should be sent to the onboard management module.
Wait for the confirmation message and check the status.
6. Build and send an
MTP2 Link Configuration Request
(
SS7_MSG_CONFIG
) to set up the MTP2
configuration parameters for monitoring operation. See the
MTP2 Programmer’s Manual
for the message
definition. Wait for the confirmation message and check the status.
7. Build and send a
Network Time Configuration
(
MGT_MSG_NTP_CONFIG
) message to each Signaling
Processor Management Module present.
