Various situations realize explanation
1) when having only center IP dispatching desk and main network obstructed in the network with Dispatch and Command Center, center IP dispatching desk can auto switching arrive back scheduling command centre, when the Any user of subsystem or the customer call 71000000 of Dispatch and Command Center 2, at first can call out the main Dispatch and Command Center that uses, main emergent extension set with the meeting configuration center IP of Dispatch and Command Center dispatching desk is 71500000.At this moment emergent extension set 71500000 is called out by the main Dispatch and Command Center that uses under the situation of judgement center IP dispatching desk off-line, will call out by DSS1 and call out back scheduling command centre, calls out center IP dispatching desk by IP network.
2) when the network of center IP dispatching desk and two Dispatch and Command Center all go wrong, or reason such as center IP dispatching desk shutdown, can not main with Dispatch and Command Center and back scheduling command centre on during normal registration.Back scheduling command centre can be under the situation of judging center IP dispatching desk off-line, by the DSS1 call forwarding to emergent extension set 71005999.If but the master has paralysed with Dispatch and Command Center, when perhaps the DSS1 between two Dispatch and Command Center also went wrong, the DSS1 that back scheduling command centre will pass through to calling higher level's switch travelled back across 71603000 (it is FH-number transform of doing that emergent extension set 71005999 converts 71603000 to) of parent office on the DSS1 trunk group between back scheduling command centre and the higher level's switch;
3) when the network of Dispatch and Command Center 1 and other command system are obstructed, the calling of other dispatch control subsystem can be as the implementation method of alternate route, call out Dispatch and Command Center 2 by IP network, again by Dispatch and Command Center 2 by the circuitous Dispatch and Command Center 1 of calling out of DSS1; (shown in Fig. 1,5)
4) when the master with Dispatch and Command Center catastrophic destruction took place, all-calls all can be called out back scheduling command centre by each alternate route of dispatching subsystem to main calling with Dispatch and Command Center.The corresponding main user that correspondence is all arranged with each user of dispatching and command system of back scheduling command centre.The calling meeting forwards corresponding user to by back scheduling command centre;
5) when the master with Dispatch and Command Center catastrophic destruction takes place, the former main function with the networking server of bearing the responsibility of the networking server in back scheduling command centre realizes authentication and redirection function to whole dispatching patcher;
6) when catastrophic destruction takes place with Dispatch and Command Center and back scheduling command system in the master, survival networking server on dispatch control subsystem 2, in the zone, the bear the responsibility function of networking server, realize authentication and redirection function between each subsystem in the zone, guarantee the calling between each the dispatch control subsystem in the zone.

3) the IP dispatching desk is set at different priorities with the networking server of two dispatcher, selects service channel according to priority.Simultaneously can switch service channel according to the variation of actual conditions.
Alternate route
When the first via by all trunking ports in when not having idle port, can select the trunking port of other route to call out automatically.Other route is exactly an alternate route.The IP route can be used as the alternate route of non-IP route in the native system.Non-IP route also can be used as the alternate route of IP route.
As shown in Figure 2, the user who dials the management of Beijing Dispatch and Command Center with the user on the scheduling subsystem in Guangzhou in scheming is an example explanation alternate route.
It is the IP route that direct route is set, and sends number " 010+876xxxxx " (010 is Beijing area code), number is replaced with " 876xxxxx " by the MDS3400 of Pekinese, by relaying outbound call PSTN.
Alternate route 1 is set is the IP route, send number " 021+010+876xxxxx " (021 is the Shanghai area code), initiate a call to the networking server by the user on the scheduling subsystem in Guangzhou, if Pekinese Dispatch and Command Center 1 and networking server can not proper communications, the networking server can inform that the scheduling subsystem direct route in Guangzhou is obstructed, Guangzhou scheduling subsystem meeting routing is by 2, send " 021+010+876xxxxx " to the networking server, the networking server can be redirected to calling Shanghai Dispatch and Command Center 2, the Dispatch and Command Center in Shanghai receives that the calling meeting replaces with number " 010+876xxxxx ", by PSTN trunk call Beijing user.
Alternate route 2 is set is local non-IP route,, send number " 010+876xxxxx ", call out to Beijing by the PSTN toll switchbroad of this locality by local relaying striking out.This route is also can't exhale the route just walked when logical to the alternate route 1 of the Dispatch and Command Center 2 in Shanghai.Each MDS3400 can also normally use in the zone.
The networking server backup
The networking server has served as the function of certificate server and Redirect Server in IP network.The function of certificate server is meant to the debarkation authentication of MDS3400 with to IP calls out between MDS3400 in the IP networking call authorization.The function of Redirect Server is meant in this dispatching patcher, and the calling between MDS3400 needs the MDS3400 of caller to call out the networking server earlier, carries out redirect services by the networking server again, and caller MDS3400 calls out on the redirected MDS3400 again.
During many MDS3400 networkings, the networking server of active/standby usefulness need be set.Carry out proper communication simultaneously and between the networking server of active/standby usefulness, the networking server of active/standby usefulness supports to manage the authentication and the redirection function of all networking MDS3400 equipment simultaneously.Just when redirected, MDS3400 can select currently used networking server according to actual conditions.After guaranteeing network failure, local survivability can be provided with the networking server of survival, bears authentication and redirection function to all dispatching and command systems of some areas temporarily.The networking department server of (referring to Fig. 3) active/standby usefulness is deployed in the different location.(referring to Fig. 4)
