It includes a V.32 quality codec, dc termination, ac termination, and an integrated hybrid, eliminating the need for an analog front end (AFE), isolation transformer, relays, optoisolator, and a 2- to 4-wire hybrid. It interfaces directly to the integrated system-side module and features Silicon Laboratories’ patented isolation technology. The Si3066 dramatically reduces the board space, component count, and cost required to implement a DAA compliant with the regulatory requirements of 49 different PTTs including FCC, JATE, China, and Korea.

The following functions can be performed with the LCS bits: While off-hook, detect if a parallel phone goes on- or off-hook. Determine if sufficient loop current is available for proper operation. Detect if there is an overload condition. 4.4.1. Loop Current Measurement When the DAA is off-hook, the LCS[4:0] bits measure loop current with 3.3 mA/bit resolution. These bits can be used to detect another device going off-hook by monitoring the dc loop current. The transfer function for LCS is shown in Figure 6 and is detailed in Table 6. The LCS bits report loop current down to the minimum operating loop current for the DAA. Below this threshold, the reported value of loop current is unpredictable and may vary between zero and the minimum operating current. When the LCS bits have reached their maximum value, the Loop Current Sense Overload Interrupt bit fires; however, LCSOI firing does not necessarily guarantee that an overload situation has occurred.
