Application Scenarios for T1-F Interfaces
As shown in Figure 9-1, the headquarters and branch of an enterprise are connected by the transmission network of a carrier. A low-rate (512 kbit/s for example) T1 channel is required to transmit services of the enterprise. In this scenario, timeslots in the T1 line need to be bundled into a channel set. For example, 16 timeslots are bundled to transmit the data service.
