Manufacturer:TI Description:6. For data calls, Part 68 rules require silence on the phone line for at least 2 seconds after a data call has been completed to allow central offices to exchange billing information and specifies the transmit level must not exceed -9dBm. The FCC rules also require that for voice calls the final system meet the requirements of Part 68 for Out-of Band Energy, and DTMF Transmit Levels. Because the CH1817 already meets FCC requirements for Part 68 registration for High Voltage isolation and Surge Protection, the certification of the product is normally a simple process that often can be completed directly with the FCC. If desired, independent testing labs are available that can test the system and submit the required paperwork to the FCC for approval. Cermetek can assist with the registration. |
