Faxes can be sent and received through Internet in transparent transmission orT.38 mode. The difference is that faxes are transmitted as voice packets over Internet in transparent transmission mode…

Explanation

Option A is correct because the statement accurately describes both Internet fax transmission modes. In transparent (pass-through) mode, the analog fax signal is encoded using a voice codec (typically G.711) and carried as RTP voice packets across the IP network - the network treats it just like a voice call. In T.38 mode, the ITU-T standard specifically designed for fax over IP, the fax signal is converted into dedicated real-time fax data packets, making transmission more resilient to packet loss and jitter than voice pass-through.

Option B (FALSE) is incorrect because the distinction described in the statement is technically accurate - the two modes genuinely differ in how they packetize fax data, and swapping their descriptions would be the error.

Memory tip: Think of Transparent = Talking (voice packets, the network "hears" it as speech), and T.38 = Transfer of data (purpose-built data packets). The number 38 can remind you it's a formal ITU standard, not a workaround.
