Telephone switching systems

Abstract

The invention relates to the generation of configuration data for use in the migration of telephone switching systems. Configuration data for use in the migration of subscribers from a first telephone switching system over to a second telephone switching system in a telecommunications network is generated by monitoring signalling information on telephone channels associated with subscribers for telephone calls conducted via the first telephone switching system. The monitored signalling information is then analysed in relation to call data produced by the first telephone switching system for the calls to identify relationships between the monitored signalling information and call data for calls conducted by subscribers. Configuration data based on the identified relationships is then stored and used to configure the second telephone switching system with mappings between the associated telephone channels and the telephone dialling numbers for subscribers.

Description

technical field [0001] The present invention relates to a method and arrangement for a telephone switching system in a telecommunications network. In particular, but not exclusively, the invention relates to generating configuration data for migration of telephone switching systems. Background technique [0002] When migrating an existing telephone switching system, such as a digital telephone switching system, to a new telephone switching system, such as a packet-based telephone switching system, a major challenge is the ability to accurately provide a mapping of telephone numbers to physical subscriber lines or channels Task. For analog lines connected directly to a digital telephone switching system, electronic records of such mappings may be obtained directly from the digital telephone switching system. Such records can be imported into packet based switching systems by some automatic means. However, for lines served by a digital loop carrier system, the relationship ...

Problems solved by technology

However, for lines served by digital loop carrier systems, the relationship between the analog ports on the digital telephone switching system and the analog ports of the central office terminal portion of the digital loop carrier system is usually recorded by only manual means, although such recording may missing, expired, or wrong

Attempting to reconstruct such records is a time-consuming and error-prone task, and even when compiled, details must be manually entered into the provisioning interface of a packet-based telephone switching system, which is itself time-consuming and error-prone
