Line row 104, emergent transfer box 2.
Telephone system wiring is overhauled as star wiring and bus-type mixing wire laying mode, wherein normal mode connection is star
Shape connects up, and emergency communication line connects up for bus-type.Each wall call socket 3 at least contains 1 301 He of normal mode jack
1 contingency mode jack 302, each normal mode jack are connected to host by 1 pair of normal communication line.It converses under normal mode
Distance can be more than 5Km；Each contingency mode jack 302 passes through other call sockets in 1 pair of emergent connection and this emergency loop
On contingency mode jack and connect, and be ultimately connected to corresponding emergency loop jack on emergent transfer box.Case of emergency
Speech range can be more than 10Km.
As shown in figure 3, emergency loop multi-tap 201：Emergent transfer box 2 is equipped with N*2 according to live emergency loop quantity N
A emergency loop multi-tap 201, i.e. each emergency loop are equipped with 2 and the emergency loop multi-tap 201 connect.Answer racing
Wiring 202：This can be realized after the emergency loop multi-tap 201 of different emergency loops is connected by emergent patchcord 202
Two emergency loops interconnect.
As shown in figure 4, wall is conversed, socket 3 needs to include at least 1 normal mode jack 301 according to scene and 1 should
Anxious pattern jack 302.
Normal mode jack 301：With Green Marker, maintenance telephone system generally is connected to by normal communication line for the jack
Maintenance 4 connecting line of telephone terminal should be inserted into this and inserted when overhauling telephone terminal 4 and work in normal mode by 1 user port of host
Hole, overhauling telephone terminal 4 at this time will rely on maintenance telephone system host 1 to work, and realize point-to-point or point-to-multipoint call conversation.
Contingency mode jack 302：The jack, will be in same emergency loop by emergency communication line generally with red-label
Contingency mode jack 302 is connected to the corresponding emergency loop multi-tap of emergent transfer box 2 by parallel way.
As shown in figure 5, the headset socket 401 of Portable overhaul telephone terminal 4:Headset side is used for being inserted into special headset
Formula is conversed.

Repeating switch 404：When maintenance telephone terminal 4 can select to make when remote call feels that called volume is less than normal
With to enhance In Call.
Ringer volume switch 405：4 ringer volume of telephone terminal is overhauled for adjusting.
Dialing keyboard 406：For overhauling the hair bell under exhalation dialing or contingency mode under 4 normal mode of telephone terminal
Exhalation.
Talking handle 407：Maintenance telephone terminal 4 send called receptor, built-in transmitter, receiver and holds key 408.
Hold key 408：To prevent that it is logical that maintenance telephone terminal 4 from being reached by transmitter surrounding enviroment noise during called
Other side is talked about, equipped with holding key 408 on talking handle, usually transmitter will be bypassed, it is impossible to send out voice, when speech needs to pin
Voice could be sent out by holding key 408.
In a specific embodiment, wall call socket 3 is distributed in 10 regions in the system, we are by each region
It is laid out as an emergency loop.The normal jack 301 in wall call socket 3 in each region passes through telephone wire → cable respectively
5 → communication cable of junction box → wiring row 104 is connected to the relative users port of system host, each normal mode jack 301
A telephone number is distributed, i.e., the circuit of each normal mode jack 301 is independent.And wall in each emergency loop
Contingency mode jack 302 in call socket 3 by communication cable and connects rear or splice connection → wiring in cablehead 5
The respective branch wire connection terminal of row 104 → extremely emergent transfer box, so the contingency mode jack 302 in each circuit are physically
All interconnect.
The operating mode of system is divided into two kinds of normal mode and contingency mode, and both of which can both be independently operated, or can
To use simultaneously.
Normal mode works：In the normal mode, it should determine that maintenance telephone system host 1 is working properly first, will overhaul
The operating mode switch 403 of telephone terminal 4 is threaded to normal mode, and the telephone connection column 402 of maintenance telephone terminal 4 by connecing
The normal mode jack 301 of telephone socket 3 is overhauled on line plug insertion wall, can be listened after 407 off-hook of maintenance telephone relation handle
To dialing tone, using dialing keyboard 406 by called phone number, maintenance telephone terminal 4 should also be inserted in maintenance telephone socket 3 at this time
Normal jack 301 in and overhaul telephone terminal 4 and work in after normal mode and can hear ring-back tone, called terminal ringing is called to pluck
It is pinned after machine and holds key 408 and can converse.If desired for carrying out group calls or simultaneous call and can dial corresponding group wailing or generally calling number,
Maintenance telephone system host 1 can accordingly be called according to dialling the number.When in communication process if you need to use telephone ear microphone
Headset need to be only inserted into the earphone jack 401 of maintenance telephone terminal 4.
Overhaul telephone system host 1 power off or because other reasons cause host that cannot work when can be used contingency mode into
Row call conversation.It can depart from host when contingency mode works to converse, detailed process is as follows：
It opens maintenance 4 battery sleeve of telephone terminal and is packed into three No. 1 batteries of section, by maintenance 4 operating mode of telephone terminal switch
403 are threaded to contingency mode, and the telephone connection column 402 of maintenance telephone terminal 4 is inserted into maintenance phone on wall by connection plug and is inserted
The contingency mode jack 302 of seat 3 lifts after talking handle 407 by the call button on dialing keyboard 406, at this time in same branch
Other terminals 4 being inserted in emergent jack 302 of road start ring, can converse after off-hook.It is such as inserted in same emergent
Terminal on circuit has multiple, these terminals meeting ring simultaneously, can also be paid attention to the class simultaneously after off-hook.Telephone terminal 4 is overhauled emergent
Pattern is equally supported to communicate using telephone ear microphone when working.Only it need to use emergent connecting line 202 that will transfer if desired for across branch communication
Converse two emergency loop multi-taps 201 is needed to be attached on case, 10 emergency loops are divided into this project, are permitted
Perhaps 10 emergency loops all connect, and can also partly connect.When not connected by emergent transfer box 2, each circuit is
One independent speech channel, the call on each circuit do not affect the communication of other branches.
System can also both of which work at the same time, mutual when working does not influence, and maintenance telephone system is only should be noted in use
The mode switch 403 of host 1 is threaded to corresponding operating mode, when overhaul telephone terminal 1 be operated in normal mode when can only
By phone insertion normal mode jack 301, can only be inserted into phone when maintenance telephone system host 1 is operated in contingency mode should
Anxious jack 302, it is abnormal that when wrong plug, can cause maintenance telephone system host 1 to work, but will not c maintenance telephone system master
Machine 1.
