TW-H6W1IR ISDN Remote Router

?? BOD Low Threshold (%) – (0 to 100) The throughput value as a percentage of total bandwidth which will cause the highest numbered ISDN port in the MLPPP bundle to hang up, thus subtracting bandwidth from the connection. Before actually hanging up however, the throughput must be below this value for the time designated in the Subtract Bandwidth Delay field.

?? Add Bandwidth Delay (sec) – (0 to 300) The amount of time in seconds the router will wait and sample the BOD Criteria before adding bandwidth once the throughput exceeds the BOD High Threshold. This prevents costly bandwidth from being unnecessarily added due to temporary bursts in traffic.

?? Subtract Bandwidth Delay (sec) – (0 to 300) The amount of time in seconds the router will wait and sample the BOD Criteria before subtracting bandwidth once the throughput falls below the BOD Low Threshold. This prevents bandwidth from being unnecessarily subtracted due to temporary lulls in traffic.

The example Multi-link PPP settings shown in the Multi-Link PPP Configuration window above assumes that ISDN 1 and ISDN 2 each have a 64kbps connection configured to dial up to the Internet. When ISDN 1 receives a packet destined for the Internet it will dial the ISP and establish a connection. If the total throughput on ISDN 1 (TX + RX) ever exceeds 80% of the 64kps (51.2kps), the router will sample the line for an additional 5 seconds. If the traffic continuously exceeds 80% for the 5 second delay time, ISDN 2 will dial up and add bandwidth to the connection. Assuming sustained traffic of 70kps, MLPPP will balance the traffic on the two ISDN ports so they are handling roughly 35kps each. If the traffic on ISDN 1 + ISDN 2 falls below 20% of the 128kps connection (25.6kps) for more than 10
