Title: Improvements in switching devices comprising switch steps with primary and secondary selectors for automatic telephone systems
IPC: H04Q3/00
Filed: 1947-07-24
Abstract: 635,727.. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. July 24, 1947, No. 19928. Convention date, Aug. 1, 1946. [Class 40 (iv)] A cross-bar selector system connects a calling line to a line in a selected direction by simultaneously finding the calling line, a free link and a free outlet in the desired direction. A line L, connected to an operating bar All in a primary cross-bar switch GA1, has access to four links m1-m4 connected to operating bars B11-12, B21-22 of secondary cross-bar switches GB1, GB2, respectively, to connect with lines F1-7 or F8-13 for traffic in one or other of two directions, the lines being grouped in gradings so that F5-7 or F10-11 are selected only if F1-4 or F8-9, 12, 13, respectively, are busy. In known manner, a register-marker operates a relay VR1 or VR2, Fig. 3, say the latter, according to the selected traffic direction, and the calling line energizes a relay GAH1 to establish one of three circuits if there should be a free link and a free outlet. (1) If either of operating bars B11, 12 and either of lines F12, 13 are idle, polarized relays PC1, PC2, and relays PC3, MV21 operate. (2) If either of B21, 22 and either of F8, 9 are idle, PC1, PC2, PC4, MV23 operate. (3) If any one of B11, 12, 21, 22 and F10, 11 are idle, PC1, PC2, PC6, MV22 operate. Relay PC2 breaks the circuit to (3) if either circuit (1) or (2) closes. Hence, one of relays PC3, PC4 or PC6 is preferred, the related relay MV21, 23 or 22, Fig. 3, also energizing and locking up. Assume that MV22 operates. Then relay FG, Fig. 2, pulls up to energize one or other preference relay PB1 or PB2, Fig. 4, which locks up to operate the related relay GBH1 or GBH2, say the former. One or other of preference relays PA1, PA2, say the former, operates and locks up to energize the select magnet SA2 and to prepare the circuit of operating magnet B12. SA2 operates magnet A11 to connect line L to link m2. The selection of a free outlet takes place at the same time as the selection of the link. Operation of relay MV22 closes contacts 221, 222 to energize one of preference relays PV1, PV2, say the former, and the corresponding relay FA10 to energize the select magnets SB3, SB13 in the cross-bar switches GB1, GB2, to operate magnet B12 to connect the link m2 to the line F10. In known manner, magnets All, B12 hold up, current over contacts b1, s1, t4 is interrupted and relay FB10 operates to release FA10, and therefore select magnets SB3, SB13 release. The above process may be repeated for each stage of selection.
