APPENDIX

1.2. A Difference of Speech Method Depending on Usage Conditions of the Station

Packet Intercom system permits hands-free full duplex conversation. However, operations of an echo canceller

or a voice switch could change depending on the stations to be used, conversation partner, or each station's

usage condition (handset or hands-free conversation), resulting in half duplex conversation.

Effective use of hands-free conversation function requires some consideration of settings and operations.

(Refer to next item.)

Speech methods related to station usage conditions are given in a table below. Use this table as a guide for

selecting appropriate stations and their speech method.

[Explanations of terms used in the table]
• Calling station:

Represents the station that makes calls and its usage conditions.

• Called station:

Represents the station that receives calls and its usage conditions.

• AEC:

An abbreviation of "Automatic Echo Canceller." Represents the state that the echo

canceller works. Full duplex conversation is always possible.

• VS:

An abbreviation of "Voice Switch." Represents the state that the voice switch works.

Half duplex conversation is possible.

• AEC + VS:

Represents the state that both echo canceller and voice switch work simultaneously

depending on the settings of microphone sensitivity and speaker output volume of

the station.

• PTT conversation:

Pressing the PTT key of the master station, IP master station, or IP remote

microphone station enables half duplex conversation.

• Full duplex:

Full duplex conversation is always possible between the handset stations.

• Conversation impossible: Conversation between the door stations, between the substations, and between

the door station and the substation is impossible.

Notes

• Models corresponding to stations are given below.

· Master station:

N-8000MS, N-8010MS, N-8011MS, N-8020MS, N-8031MS, N-8033MS

· Door station:

N-8050DS

· IP master station:

N-8500MS, N-8510MS, N-8600MS

· IP Remote microphone station: N-8610RM

· IP door station:

N-8540DS, N-8640DS, N-8650DS

· Analog master station:

N-8410MS

• In conversation with substations, handset conversation is required for the master station and IP master.

In this case, the type of conversation method is half-duplex conversation.

• In conversation between both analog master stations connected to the same Sub-station interface unit, half

duplex conversation is made between the stations when both are engaged in hands-free conversation, but

full duplex conversation when engaged in other conversation mode.

• When the N-8000CO outside line interface is connected, conversations between outside line telephones and

intercom stations are half-duplex using the voice switch if the station is in hands-free mode, and full-duplex if

the station is in handset mode.

• Operation of the analog telephone connected to the N-8000AL is the same as for the master station handset.
