RE: internal modem
Keep in mind that UL1459 is obsolete. The overvoltage testing is now covered in UL60950. Regards, Alex McKinney Safety Engineer LXE, Inc.

Re: internal modem
but we are unfamiliar with telephone line connectivity. Dan, The following standard will need to be met: TIA/EIA/IS-968 Technical Requirements for Connection of Terminal Equipment to the Telephone Network (it replaces the FCC Part 68).

Terminal Equipment approval has been privatized and is now under the control of ACTA.
