ITSP Dial-In Access (SN4110 Series FXO)
Internet Telephony Providers (ITSPs) have different options for giving access to their customers. E.g.
direct connections over broadband Internet, Call-shops or dial-in access. This works as follows:
q
The customer calls a local number where a SmartNode is connected (originating Gateway)
q
The SmartNode provides a 2 nd dial-tone so that the customer can dial the destination number
q
Based on this second number the call is routed to the terminating gateway
q
The terminating gateway picks up the line and dials the destination number
