Abstract
Abstract A method for providing narrowband-related service features to subscribing broadband lines comprises establishing a composite voice path interconnecting a narrowband server and the subscribing broadband line via a broadband switching fabric. Particularly, a call set-up signal is received in a broadband call processor, converted to narrowband signaling format and extended to a designated narrowband server. Responsive to receipt of the call set-up signal, the designated narrowband server establishes a narrowband voice path interconnecting a narrowband network element to a synchronous-asynchronous converter. Subsequently, the broadband call processor establishes a broadband segment interconnecting the subscribing broadband line with the synchronous-asynchronous converter. The broadband segment corresponds to the narrowband voice path to form a composite voice path. The composite voice path is used by the designated narrowband server to provide narrowband-related service features to the subscribing broadband line. After a call in which narrowband-related features may be invoked has been disconnected, the composite voice path is released.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
155 words
In an integrated telecommunication switching system comprising a broadband switching fabric which serves at least one broadband subscriber and a narrowband server associated with the broadband switching fabric, a method for providing service features to the broadband subscriber comprises the steps of: receiving call set-up signals in a broadband call processor; the broadband call processor converting the call set-up signals to narrowband signaling format; the broadband call processor delivering the converted call set-up signal to a designated narrowband server; the designated narrowband server establishing a narrowband voice path to a synchronous-to-asynchronous converter (SAC) in response to receiving the call set-up signals; the broadband call processor establishing a broadband segment corresponding to the narrowband voice path established by the designated narrowband server to form a composite voice path interconnecting a subscribing broadband line to the designated narrowband server; and the designated narrowband server providing service features to the subscribing broadband line over the composite voice path.
Claim 2
Dependent Claim
155 words
In an integrated telecommunication switching system comprising a broadband switching fabric which serves at least one broadband subscriber and a narrowband server associated with the broadband switching fabric, a method for providing service features to the broadband subscriber comprises the steps of: receiving call set-up signals in a broadband call processor; the broadband call processor converting the call set-up signals to narrowband signaling format; the broadband call processor delivering the converted call set-up signal to a designated narrowband server; the designated narrowband server establishing a narrowband voice path to a synchronous-to-asynchronous converter (SAC) in response to receiving the call set-up signals; the broadband call processor establishing a broadband segment corresponding to the narrowband voice path established by the designated narrowband server to form a composite voice path interconnecting a subscribing broadband line to the designated narrowband server; and the designated narrowband server providing service features to the subscribing broadband line over the composite voice path.
Claim 3
Dependent Claim
42 words
The method of claim 1 wherein the step of the broadband call extending the converted call set-up signal to the designated narrowband server comprises the step of: transmitting the converted call set-up signal to the designated narrowband server via a message switch.
Claim 4
Dependent Claim
34 words
The method of claim 1, and further comprising the step of: the designated narrowband server releasing the narrowband voice path to the SAC upon receipt of a disconnect signal from the broadband call processor.
Claim 5
Dependent Claim
32 words
The method of claim 1 further comprising the step of: the broadband call processor receiving the call set-up signal from a party other than a caller associated with the subscribing broadband line.
Claim 6
Dependent Claim
43 words
The method of claim 1 further comprising the step of: the designated narrowband server receiving a call set-up request signal directed to the subscribing broadband line; and the designated narrowband server extending the received call set-up request signal to the broadband call processor.
Claim 7
Dependent Claim
114 words
In a broadband switch serving at least one broadband subscriber line, a method for providing service features to the broadband subscriber line comprises the step of: receiving a call set-up signal; determining whether the received call set-up signal originates from a broadband subscriber line which subscribes to narrowband-related service features; responsive to a determination that the broadband subscriber line subscribes to narrowband-related service features, converting the call set-up signal to narrowband signaling format; extending the converted call set-up signal to the narrowband server; receiving an acknowledgment signal from the narrowband server; and establishing a broadband segment to interconnect the broadband subscriber line to a synchronous-to-asynchronous converter (SAC) in response to receiving the acknowledgment signal.
Claim 8
Dependent Claim
114 words
In a broadband switch serving at least one broadband subscriber line, a method for providing service features to the broadband subscriber line comprises the step of: receiving a call set-up signal; determining whether the received call set-up signal originates from a broadband subscriber line which subscribes to narrowband-related service features; responsive to a determination that the broadband subscriber line subscribes to narrowband-related service features, converting the call set-up signal to narrowband signaling format; extending the converted call set-up signal to the narrowband server; receiving an acknowledgment signal from the narrowband server; and establishing a broadband segment to interconnect the broadband subscriber line to a synchronous-to-asynchronous converter (SAC) in response to receiving the acknowledgment signal.
Claim 9
Dependent Claim
30 words
The method of claim 6 wherein the step of determining whether the broadband subscriber line subscribes to narrowband-related service features comprises the step of; accessing a broadband subscriber line database.
Claim 10
Dependent Claim
27 words
The method of claim 6 wherein the step of converting the call set-up signal to narrowband signaling format comprises the step of: accessing a broadband-to-narrowband conversion program.
