DE1033730B - Arrangement for monitoring central re-folders - Google Patents

Description

In the country remote dialing, the ones given by the subscriber station are used to establish the connection Pulse trains recorded in a memory device, which in turn for the routing control and the Verzonumg briefly requests a central link, the so-called rearrangement.

For a telephone exchange, only one such re-folder is in operation, while a reserve re-folder is ready to take over its activity in the event of failure of the operational re-folder. For the The security of the discussion is the constant operational readiness of the rearrangers an indispensable prerequisite. which must be constantly monitored by suitable means.

The invention shows an arrangement for monitoring such central switching elements in which the Expenditure of high-quality test equipment and an additional burden on the reorder due to control connections be avoided. This is achieved in that the recorded in a memory Information is transferred to both central re-folders and that the one re-folder the Evaluation both to the memory and to a comparison device, while the reserve

In the operating state with monitoring, ie the connection of both rearrangers, the plug connections 1, 2, 4, 5, 6 and 7 are activated.

In the operating state without monitoring, the plug-in connections 1 and 4 and the plug connections when the reorder C / 2 is in operation 2 and 3 actuated.

This principle of optional interconnection can advantageously be used to to make changes in the re-folder, e.g. B. Route or zoning changes to make by the Storage can only be connected to one folder while the other is being changed, and then vice versa. Both can then be switched on for monitoring purposes.

Claims (3)

PATENT APPLICATIONS: 1. Arrangement for monitoring central switching elements, in particular for telephone systems with storage operation, in which, in addition to a central re-folder in operation, a reserve re-folder is available, characterized in that the information recorded in a memory (Sp) two central re-folders (Ul, U 2 ) and that the one re-folder (t / l) gives the evaluation both to the memory (Sp) and to a comparison device (V) , while the reserve re-folder transmits its evaluation only to the 'comparison device, in which a signal if the two evaluation information are inequality is given to memory. 2. Arrangement according to claim 1, characterized in that the connecting lines between Re-folders, memory and comparison device for the optional activation of the individual re-folders via plug-in connections (1 to 7). 3. Arrangement according to claim 1, characterized in that in addition to monitoring the central reallocation errors in the connection manifolds (e.g. short circuit, earth fault, interruptions in the comparison device) are determined and signaled.
