Chapter 1 GENERAL DESCRIPTION
8. TWO CALL RESPONSE METHODS
Two different call response methods are available to the N-8000 system: "Sequential Response" and "Selective
Response." The former is used in "Master-to-Master" systems that allow free communication between Master
Stations by calling one another, while the latter is used in "Master-to-Sub" systems in which substations installed
in different locations call one specified Master Station.
Note
The entire system is set for Sequential Response. A Master Station set for Sequential Response cannot be
used in combination with a Master Station set for Selective Response.
8.1. Sequential Response (Master-to-Master System)
This method is used in systems in which the Master Stations are mainly used and calls are freely made. Its
main applications include communication and paging, and received calls are responded to on a first-come-
first-served basis. Response can be set to either "Continuously Called Station Response" or "Auto-Respond"
modes. Selecting "Auto-Respond" eliminates the need for button operation and allows conversations to be
started instantly.

• Only one call is accepted.
• The second call is placed in busy mode.
• Responds to the first call.
(Note: However, the second calling party can
break in on the conversation using Emergency
Interrupt to request the called party to return
the call after conversation completion.)
8.2. Selective Response (Master-to-Sub System)
This method is used in systems in which a Master Station is called from multiple Substations or Door Stations. Its
main applications include interphone and nurse call systems, and the Master Station selects which Substation
to respond to. Auto-Respond cannot be used in this system.
