How many S/P Phones or Handsets can a basic S/P Phone Station support?

• A. 1-4
• B. 1-6
• C. 2-6
• D. 3-8

Answer: (B)

The idea is how many handsets a single S/P Phone Station can serve without losing intelligibility. A basic S/P Phone Station is designed so several users can be connected to the same line without any power source, sharing one circuit. The practical limit for reliable operation is six handsets, because adding more tends to load the line too much and reduce volume and clarity. So you can have from one up to six handsets connected to a basic station, with six being the upper limit in a standard setup.
