The type of interface. The POS-Access mode has four types: FCM-Access, ASYNC-Access, simulating POSPAD device, POSPAD-Access. FCM-Access mode means POS and router are connected through PSTN. In this case, posPosInterType should be set to fcm. ASYNC-Access mode means POS and router are connected by asynchronous cable. In this case, posPosInterType should be set to asy. Simulating POSPAD device means router connects POS through asynchronous cable and connects another router whose connect mode is pad-server through X.25 network. In this case, posPosInterType should be set to pad-client. POSPAD-Access mode means router connects POSPAD device through X.25 network. In this case, posPosInterType is pad-server. The posPosInterType can't be set to pad-server. It is autogenerated when POSPAD device initiates a connection to the router.
