Communication system control arrangement

A call processing arrangement for a communication switching system having physical resources configurable to provide communications for terminal logical channels of the system and a resource management arrangement responsive to receipt of requirements signals for configuring the physical resources into (a) physical communication channels corresponding to logical communication channels and into (b) physical call paths between the physical channels corresponding to logical call paths, the call processing arrangement comprising:

• first program controlled call processing means having a single process responsive to receipt of first message signals having first portions requesting control functions for calls and having second portions identifying calls to broadcast program sources for any one of the logical channels, for processing call information to generate the requirements signals for controlling the logical call paths for the calls between the one logical channel and a logical channel of a broadcast program source, independently of the physical resources;
• second program controlled call processing means having a plurality of processes responsive to receipt of second message signals having first portions requesting control functions for calls and having second portions identifying point-to-point calls for any one of the logical channels, each one of the plurality of processes for processing call information to define the requirements signals for establishing and controlling the logical call path for an individual one of a calling and a called portion of one of the point-to-point calls between the one logical channel and another at least one logical channel, independently of the physical resources;
• and
• signal routing means responsive to receipt of the first and second message signals from subscriber terminal equipment for processing the second portions of the received signals (a) to identify first message signals and send them to the first call processing means and (b) to establish unestablished processes of the second call processing means and send second message signals to established processes of the second call processing means;
• the first and the second signals having identical first portions to make subscriber function requests from subscriber terminal equipment independent of differences between the first and the second call processing means.

A control arrangement for establishing calls in a communication system in response to receipt of message signals from terminal equipment, the arrangement comprising:

• first program controlled means responsive to receipt of first message signals having a first portion requesting establishment of calls and having a second portion identifying certain calls, for establishing the certain calls by a single process;
• second program controlled means responsive to receipt of second message signals having a first portion requesting establishment of calls and having a second portion identifying calls other than the certain calls for establishing each of the other calls by a plurality of processes, each process for establishing an individual one of a calling and a called portion of the call;
• and
• signal routing means responsive to receipt of the first and the second message signals from subscriber terminal equipment for processing the second portions of the received signals (a) to identify first message signals and send them to the first means and (b) to activate the processes of the second means and send second message signals to the processes of the second means;
• the first and the second signals having identical first portions to make requests from subscriber terminal equipment for call establishment independent of differences between establishment by the first and the second means of the certain and the other calls, respectively.

A control arrangement for establishing calls in a communication system having physical resources configurable to establish calls in response to receipt of message signals from subscriber terminal equipment, the arrangement comprising:

• first program controlled call processing means responsive to receipt of first message signals having a first portion requesting establishment of calls and having a second portion identifying certain calls, for generating by a single process requirements signals to establish the certain calls;
• second program controlled call processing means responsive to receipt of second message signals having a first portion requesting establishment of calls and having a second portion identifying calls other than the certain calls, for generating by a plurality of processes requirements signals to establish each of the other calls, each process for generating requirements signals to establish an individual one of a calling and a called portion of a call;
• third means responsive to receipt of the requirements signals for directing configuration of the physical resources to establish the calls;
• and
• signal routing means responsive to receipt of the first and the second message signals from subscriber terminal equipment for processing the second portions of the received signals (a) to identify first message signals and send them to the first call processing means and (b) to establish the processes of the second call processing means and send second message signals to the processes of the second call processing means;
• the first and the second message signals having identical first potions to make requests from subscriber terminal equipment for call establishment independent of differences between the first and the second call processing means.

A control arrangement for a communication switching system having physical resources configurable to provide communications for terminal logical channels of the system, the control arrangement comprising:

• first program controlled call processing means having a single process responsive to receipt of first message signals having first portions requesting control functions for calls and having second portions identifying calls to broadcast program sources for any one of the logical channels, for processing call information to generate requrirements signals for controlling logical call paths for the calls between the one logical channel and a logical channel of a broadcast program source, independently of the physical resources;
• second program controlled call processing means having a plurality of processes responsive to receipt of second message signals having first portions requesting control functions for calls and having second portions identifying point-to-point calls for any one of the logical channels, each one of the plurality of processes for processing call information to generate requirements signals for establishing and controlling a logical call path for an individual one of a calling and a called portion of one of the point-to-point calls between the one logical channel and another at least one logical channel, independently of the physical resources;
• program controlled resource management means responsive to receipt of the requirements signals for configuring the physical resources into physical communication channels for the logical channels and into physical call paths between the physical channels for logical call paths;
• and
• signal routing means responsive to receipt of the first and the second message signals from subscriber terminal equipment for processing the second portions of the received signals (a) to identify first message signals and send them to the first means and (b) to establish unestablished processes of the second means and send second message signals to established processes of the second means;
• the first and the second message signals having identical first portions for requesting identical subscriber call functions to make requests from subscriber terminal equipment for subscriber call functions independent of differences between the first and the second call processing means.
