1.3.9 Recommendations for System Configuration
General guideline: a ratio of 6/1 (for every 6 lines, 1 port). There are 2 questions to ask when
considering how many ports are desirable:
• Are the ports answering all incoming calls or just forwarded/transferred calls?
• If they are answering incoming calls, how busy are the lines?
The guideline above (6/1) usually works well with moderate traffic. However, this may have to
be modified for heavy traffic. Recommendations are outlined in the following charts.
Notes
• The KX-TVS125 can support a maximum of 6 ports.
• The KX-TVS225 can support a maximum of 12 ports.
• The KX-TVS325 can support a maximum of 24 ports.
