The utility model will be an example with (1) among 90 Fig. 1, (2), (3), be that the trunking diagram that the unit expansion is formed describes in further detail with 30 (1) or (2) or (3):

One, individually exhale, group calling, the action specification of exhaling together:

Send out and exhale user's off-hook

, K changes with the automatic telephone unit automatically by point and joins, and start subscriber line circuit YH this moment, and marker B looks other and exhales the user, selects link

Optional equipment JX takies register(system) JF by note, and enabling signal equipment XH, send out exhale the user to listen dialing tone to dial to exhale, group calling or when wailing together, individually exhale, group calling or exhale relay G, Z together or the J action.

1, during individual exhaling, Called Subscriber a or the action of b contact, loudspeaker are accepted to send out and are exhaled sound, and it is as follows that its signal is sent route

Signalling arrangement XH sends out and exhales sound → cord circuit SL → electric wire connecting junction B outlet → amplifier

→

Called Subscriber loudspeaker call accepted sound after 1～3 second calling tone stop, send out and to exhale the user to speak, loudspeaker are accepted speech, if K action behind the off-hook during speech of Called Subscriber off-hook, loudspeaker staccato, Called Subscriber are talked about and are sent words with unit, in the time of the Called Subscriber off-hook, cord circuit SL, the action of control SB contact has disconnected amplifier in and output, sends out and exhales user's on-hook, this calling finishes, and parts restore.
