Configuration Options

Tables A-2 and A-3 provides the maximum payload rates achievable for each DSL line rate and the number of time slots required to achieve that payload rate. For G.703, the payload rate depends on whether you are using signaling (time slots 0 and 16) or data only (time slot 0).
