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, hh3cposPosInterType should be set to fcm. ASYNC-Access mode means POS and router are connected by asynchronous cable. In this case, hh3cposPosInterType 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, hh3cposPosInterType should be set to pad-client. POSPAD-Access mode means router connects POSPAD device through X.25 network. In this case, hh3cposPosInterType is pad-server. The hh3cposPosInterType can't be set to pad-server. It is autogenerated when POSPAD device initiates a connection to the router.
