The invention relates to being able to bring a switching status in which three or arrangement for the production of connection or also more connections, which are partly also Consultation and switching connections can be in a waiting state at the multi-level Time division multiplex telephone exchange meeting connection are involved. Such a connection system, In particular, time-division multiplex extensions can generally fertilize in one of the d, ii. on telecommunication systems, in which the procedures explained above correspond accordingly see the individual connections to be brought about, with a search that is connected to one another in time, namely a search for a common un-free one Pulse sequences are modulated on what is a temporal pulse phase, spread over a corresponding plurality Bundling of the individual transmission channels has to extend to io of line trunk groups. With increasingly multiplex rails allowed. Such multiplex rails mend the number of each on one connection each belong to a plurality of subscribers- participating connections increases, but now also the em connections to; the internal blockages thereby flowing to a line trunk group on the loss, i. e. on Pooled participants are strong about their Λπ- losing connection attempts Closing lines by means of time channel- »5 inserted therein. To comply with specified loss limits switch periodically, impulsively, to one of the switches, therefore, if necessary, the number of the respective ones Connection allocated pulse phase to the receiver connections per line group reduced relevant Mulfiplex rail can be switched on. Besides being what, meanwhile, turned into a bad salvage Subscriber connection groups can use the group's own facility such a time-division switching system would become separate.

Derten line trunk groups summarized voice The invention now shows a way, such energy intermediate storage devices or to better meet problems and without whose offices leading office connections show such a strong increase in internal influence (see e.g. German Auslegeschriften 1 207 451 and blocking connections between each more 1 243 247). In such a time, as two connections are to be established per line group. The Erfinmultiplex switching systems Address circulation concerns a multi-level time division multiplex switch memory for the correct phase storage of the treatment system, each with a plurality of subscriber addresses the time division multiplex rails associated with the mer connections involved in a connection, Connections of the line group in question for the purpose of being more appropriately connected to form a line group Actuation of the timely channel in each case 30) .pfaßten subscriber via their connecting lines switch provided; furthermore, a time channel switch inserted in the multiplex mittc.s is periodic Rails of the individual connection g .. jppen one-on-one impulsively each to one of the relevant verander connecting coupling network with the pulse phase allocated under the binding can be switched on, Influence of also stored in associated circulating address memories with separate line trunk groups Corresponding addresses also 35 volume-filled speech energy intermediate storage device phase-correct operated crosspoint switches or to other offices. connections, still with one per connection group

In switching systems of the above-mentioned provided circulating address memory for the phase type, it is known that connections between the correct storage of the addresses of each of the two connections involved in a connection are fundamentally affected in such a way that two connections are separated when there are connections between fenden connections of the connection group in question Connection groups each for the purpose of phase-correct actuation of the respective time channel switch of the respective connections time channel switch, and finally with one of the and the relevant multiplexing multiplex rails of the individual connection groups of the affected connection groups with one another 45 interconnecting coupling network with other interconnecting crosspoint switches of the coupler common to the influence of corresponding address groups stored in the associated address dump network for one of the corresponding address groups stored in the associated connection memory Per-switch the free pulse phase which is then allocated to the connection which is also activated with the correct phase. Such a time-division multiplexing can be operated in pulses and that, according to the invention, connections between two connections are identified by the fact that, in addition to one or more of the same connection group, the time channel switches of the known connection group (s) of connections two connections and the time channel switch of a voice energy buffer and group-enabling voice energy buffer that is available between subscribers of one and the same connection, the multiplex bars of the subscriber connection group relating to a particular connection group with the subscriber connection group that is provided with voice energy buffers, those of the separate interface group Language switching connections between two already single-point switches to two separate connections connected in the enders involved On the one hand, and a connection group free and then the relevant third connection on the other hand, the putpheses assigned to the connection are brought about periodically by being activated in pulses in the circulating address memory. special line group the address of a free

Energy buffers and memories for other offices are provided, Ps can then bring about connection connections between one already connected to one of the terminals, namely in the following way: In the corresponding connection with a second connection, for example the circulating address memory of the aforementioned Geson - Assign the office connection Uem of the line group to which line group is assigned the address of a free 5 GU, participating switchboard, such as the switchboard for the desired inquiry or switchboard PL of the line group GP, and a voice connection used voice energy third connection, such as B, the subscriber line buffer both to a pulse phase g TNn the subscriber line group GN, via which stores the connection between the first voice energy buffer of said connection and the second connection is allocated and with the terminal group of voice energy 'buffer the address of the first connection or switching and switching stations (PL) are brought about in the address associated with it, this line group is now written in the waste memory, as well as to a deviation from the in F i g. 1 indicated behaves pulse phase, which is the at the recall or intermediary Nissen two address circulating memory per a lung connection participating third terminal züge- i ₅ for the addresses of voice energy intermediate divided and in the züge- save it with its address and from the attendant consoles, granular circulating address memory has crept in; For this purpose, so that in turn are coming in the store in question the said separate line group address circulation storage UKF of the LAD, the address of a free and then the addresses of the 30 wanted Vermiltlungsverbindung with each of the gepelnetzwerks KF the multiplex in claim seemed the particular line groups made in Zwischenspeicheradressenumlaufgugleich Voice energy buffer and the connecting crosspoint switches are stored in phase with a pulse phase that is stored right for the connection. This then results for the connection groups G 1 or GP, GN and connection Uem between the exchange PL and the exchange unit and with which the address CU is assigned a pulse phase as shown in FIG. 2c of the exchange in the exchange . In this case, the connection of the rail labeled with the circulating address memory of the separate connection CU with the group labeled GS 'is written; on the other hand, the ninth track is indicated that this is the address of the relevant Sprachcnergie-interim assignment of two address circulation memories, the memory in the associated Adrcssenumlauffcu one and the same time division multiplexing rail is saved to a pulse phase, which the to Zeitkanalschaltsr via their Control the decoder. The switching of the third compound involved Anrelativ e position of the respectively occupied pulse phases relative to one end TNn is allocated and the other whose address corresponds to that of FIG. 2b, so that in the associated him Adresscnumlaufspeichcr UN should be unnecessary insofar further explanations. is enrolled. At the same time thus are again in Unlike the circumstances in Fig. 2b 35, however, the candidate Adressenumlaufspeiehern Became one of the two pulse phases by UKF the switching network KF, the addresses of the the existing link between itself Multipiexschienen the particular line groups together connected connections, for example interconnecting crosspoint switches pha-Hveise that is to say the connections TIl and Uem, allocated correctly stored. Formed for the on-pulse phase p _{a involved} and only the pulse phase with 40 tapping then results in a pulse phase transmitter, the address of the third connection, exemplary assignment as it is illustrated in FIG. 2d. In the example, then, ratios, the address of the connection TNn, circulating memory is written in the to-unlike those shown in Fig. 2c shown Vergehörigen in now is not the with GU but the mil one is called via its terminal group GN and GP track with the the speech energy intermediate used connected 45 rail with GS 'designated connection group, since now, in contrast / u Go memory, for example so the modified previously discussed and the Fig. 2c vcrdcut terminal group GU, extending free dialing clear ratios not the terminal group GU ₁ allocated. Such a procedure is also possible here in each but also the connection group GP , since the separate connection group contains voice energy buffers for the implementation of voice energy buffers and official callback connections. As regards the main pulse phase (p.), On the one hand, and the actual pulse phase coverage, the relationships in the case of FIG. 2d with the connection between subscriber line 711 and those in FIG. 2c hastily, so that sil.Ii of the line group Cl and the exchange line should not need any further explanations.
If this separate line group is occupied, 55 the same applies to the 1 ig. 2c, which fell · on the other hand, at this pulse phase of the memory from the h ig. 2d and 2c are distinguished by the fact that space in the second, for the addresses of speech energy, is now the track labeled (MT, both with the address circulation provided with the intermediate storage, with OU and with the storage with Gl and UP, respectively, which is still free and therefore In it the address is connected to the next track. The pig. 2e shows the language used for the inquiry connection that is used for the pulse phase assignment, which is recorded in the feedback energy buffer, inquiry connections and / or communication connections without entailing a pulse phase selection process between one with a second connection, such as the Amisansdiluf, the same applies if, in deviation from Uem, the first connection involved, such as the part of the modification just discussed, not In * s mhmeranachlufl TIl, or Vermiiihtngsplaiz (PL ] the line group OU the time-division multiplex * Vermin- and a third line, such as the subscriber age according to Fig. 1, but in the separate connection TNn, results when this Ruckfraawerbin connection group GP also interim fertilization of language energy via the language energy interim storage

a separate connection group can be brought about, in the language energy intermediate storage, as well as leading to other offices Amtsanschliisse and VermiUlungspHitze are summarized, with the line group then for the three different types of connections have three circulating addresses.

In such a modification of the strength in F, shown multistage time division switching system 1 is then in the corresponding Adressenum- transit memory of such a separate terminal group, the address of a speech energy Zwischenspeichcrs used for the desired call-back connection or exchange connection first of all to a pulse phase p _a (s. F ig, 2e), which is assigned to the connection between the first connection (711) or switchboard (PL) and the second connection (Uem) and with which the address of the first connection TIl or the switchboard PL in the associated one Circulating address ao memory is written. On the other hand, the address of the relevant speech energy buffer memory ^ u of a pulse phase p _b (see Fig. 2e) is stored, which is shared with the third connection (TNn) involved in the inquiry or switching connection and with that of the latter Address is written in its associated circulating address memory UN . At the same time, the addresses of the crosspoint switches pht connecting the N * iltiplexschiene of the relevant line groups with each other are again stored correctly in the relevant address circulation memories of the coupling network.

As has already been explained above, the time division multiplex switching system according to the invention can also be modified to the effect that RUckfrageverbinduiigen and / or switching connections between a connection already on a connection with a second connection, such as. B. the office connection Uem the line trunk group GU, involved first connection, such. B. the subscriber Ti 1 of the line group Gl, or switchboard, such as the switchboard Pl of the Anschlussgruppc GP, and a third connection, such as. B. the subscriber line TNn of the subscriber line group GN, as well as connections between two subscriber lines of different line groups, for example, like a connection between the subscriber line 711 of the line group Gl and the subscriber line 722 of the line group G 2, directly over (lie multiplex rails of the line groups concerned, in the considered For example, via the multiplexing rails MX, MU, MP, MN, by periodically actuating the line-channel switches and crosspoint holders in question, a single pulse nose assigned to the relevant inquiry or communication connection can be brought about. This pulse phase is known there · * ° in the case of a pulse phase allocated to the actual connection between the aforementioned first connection, for example the switchboard, and the -cited second connection. A pulse phase assignment results in the participating connection groups ON, · * OU and Gl or OP , how is never illustrated by FIG. 2g. Here again the meaning already explained above can be attributed to the broad or narrow pulse phase marks; indicated by the occupancy of the pulse phase p _b isi in Fig, 2g that the for the inquiry or. Switching connection used pulse phase is reassigned in a free dialing process extending over the line groups in question. While this requires a free selection process extending over three line groups to select a pulse phase that is free in common in the three line groups, a free dial process extending over two line groups is sufficient if for the inquiry or switching connection in addition to the previous connection between the already interconnected Connections (Uem and 711 or Pl) assigned pulse phase a further pulse phase is zrgeteili. In this case, there is a pulse phase assignment in the line groups GM GU and G1 or GP involved, as shown in FIG. 2f. Here, too, the broad or narrow pulse phase marks have the meaning already explained above, namely the meaning of a connection address stored for the pulse phase in question, which (with a wide pulse phase mark) causes the relevant time channel switch to be actuated periodically and in pulses in accordance with the phase, or not (in the case of a narrow pulse phase mark) causes.
