Hi,
When a Peripheral Gateway goes through its startup ritual, the Node Manager on the Peripheral Gateway starts all the processes. The Peripheral Gateway has its own copy of a message delivery service. When MDS initialized, it will go into service. If it is duplex, the OPC Process will do its state transfer similar to the Router-to-Router state transfer. If the OPC can not connect to its peer, OPC will send an initialization request to a process call PGAgent. PGAgent will attempt to establish an active path to one side or another of the Central Controller. It will connect to an active path on one side and an idle path to another side.
Once an active path has been established to the Central Controller, OPC will request from the Router its configuration information. The Router will then send information back about what it wants to get from the PG: Tell me about this ACD. How many agents are there? What are their skills? Tell me about any call arrivals and termination events, etc. Once OPC receives the config from the Router, it will make the connection to the switch via a process called a PIM, or Peripheral Interface Manager. There is a different type of Peripheral Interface Manager for each type of switch that we connect to. The PIM will connect to the switch. The PIMs job is to maintain the connection to that ACD or VRU and normalize the message stream from that ACD back to the Call Router. The PIMs job is to convert ACD speak to ICR speak and pass that information along. Once the PIM connects to the switch, the OPC process will report a peripheral online status message back to the Call Router.
