Question

If Plain Old Telephone Service (POTS) and Digital Subscriber Line (xDSL) service are fed on a single path through an interrupt-style enterphone without using an ISB or POTS Splitter, the system will interrupt a phone call when activated but not the xDSL service.

a) True
b) False

Answer 1

The claim that an enterphone system will interrupt a POTS phone call but not the xDSL service when they share the same path without a splitter is false. Both services could potentially be disrupted due to sharing an unfiltered line.

Step-by-step explanation:

The student's question addresses the compatibility issue between Plain Old Telephone Service (POTS) and Digital Subscriber Line (xDSL) when they are both connected through a single path without a POTS Splitter or an Integrated Services Block (ISB). The assertion that an enterphone system will interrupt a POTS phone call but not the xDSL service when activated is, in principle, False. While xDSL service typically operates at higher frequencies than traditional telephone services, an enterphone system designed to interrupt the phone line for signaling could potentially disrupt both services if they are sharing the same unfiltered line. In practice, a POTS splitter is necessary to prevent interference between voice and xDSL data signals, ensuring that the data connection is not interrupted by line-seizing equipment like an enterphone.
