Overflow handling, if input to SmartNode is higher than maximum output. Can the overflowing calls be sent via the fall-back ISDN-line?

| The WAN access speed is expected to be large enough to handle all voice connections on the SmartNode. Moreover the voice portion of the used access bandwidth is expected to be small with respect to total bandwidth. For example a DSL access with 700kbps or more may be used for 4 voice channels (SOHO, SME) applications. A subscriber with an ISDN PRI interface is expected to have at least 2Mbps access speed. In such a configuration there can be no voice overflow in the SmartNode. The fallback connection is used if a call cannot be established at set-up, because the network is down or congested or because the opposite gateway is not available. | |
