TR3271 Management Programming Manual

MANAGEMENT PROGRAMMING FOR TR3271
Communicating With the TR3271 Subsystem
Regardless of the language you are using, the tasks an applica-
tion must perform when communicating with either SCP or the EMS
distributor process are as follows:
1. Establish communication with SCP or the EMS distributor
process.
2. Call SPI procedures to build a message.
3. Send the message to SCP or the EMS distributor process.
4. Receive the response.
5. Check for error codes and handle any error.
6. Decode the response.
7. Take appropriate action and return to step 2, if necessary.
8. Terminate communication with SCP or the EMS distributor
process.
All data-communications subsystems must use the same message
protocol for communicating with SCP. For details on this
protocol, refer to the
Communications Management Programming
Manual
and the
Distributed Systems Management (DSM) Programming
Manual
. For details on communicating with the EMS distributor
process for the TR3271 subsystem, refer to Section 7, "Event
Management." For general information about communicating with
the EMS distributor process, refer to the
Event Management
Service (EMS) Manual
