All digital DSL system migration
View Patent ↗The described implementations relate to migrating from a Digital Subscriber Line (DSL) system implementing Plain Old Telephone Service (POTS) equipment that handles analog communication signals to a DSL system that implements All Digital (AD) enabled equipment capable of handling DSL data and Internet Protocol (IP) telephony traffic.
1. A method, comprising:
enabling an all digital (AD) mode associated with an AD enabled Digital Subscriber Line (DSL) linecard that supports at least the AD mode and another mode that supports DSL and legacy baseband service;
detecting implementation of at least one AD capable Customer Premises Equipment (CPE), the act of detecting including detecting CPE signature circuitry associated with the AD capable CPE, the CPE signature circuitry indicating compatibility with the AD mode of the AD enabled DSL linecard; and
coupling the AD enabled DSL linecard to a splitter, the splitter to handle analog signals associated with a customer POTS device and DSL signals associated with a computing device interfaced with the Internet.
2. The method according to claim 1 , further comprising:
replacing a conventional DSL linecard with the AD enabled DSL linecard having integrated line testing functionality; and
coupling a POTS card to the AD enabled DSL linecard.
3. The method according to claim 1 , wherein the AD enabled DSL linecard is to process Internet Protocol (IP) telephony signals and DSL data signals in the AD mode.
4. The method according to claim 1 , wherein the act of detecting the CPE signature circuitry is performed by line testing functionality associated with the AD enabled DSL linecard or by line testing functionality associated with a POTS card.
5. The method according to claim 1 , wherein the act of detecting includes detecting the AD capable CPE by way of a capability list exchange initiated at a Central Office (CO).
6. The method according to claim 1 , further comprising:
decoupling a splitter coupled to AD enabled DSL linecard; and
decoupling a POTS card coupled to the AD enabled DSL linecard.
7. The method according to claim 1 , further comprising:
identifying a POTS signal channel associated with at least one all digital (AD) capable Customer Premises Equipment (CPE); and
disabling the POTS signal channel.
8. An apparatus, comprising:
an all digital (AD) enabled Digital Subscriber Line (DSL) linecard to support at least an AD mode and another mode that supports DSL and legacy baseband service, that the AD enabled DSL linecard having line testing functionality enabling detection of at least all digital (AD) capable Customer Premises Equipment (CPE); and
a network management module to initiate detection of at least one AD capable CPE and enablement of the AD mode of the AD enabled DSL linecard, the detection of the at least one AD capable CPE implemented by detecting CPE signature circuitry associated with the AD capable CPE, the CPE signature circuitry indicating compatibility with the AD mode of the AD enabled DSL linecard.
9. The apparatus according to claim 8 , wherein the network management module is to initiate the AD enabled DSL linecard to detect the at least one AD capable CPE.
10. The apparatus according to claim 9 , wherein the AD enabled DSL linecard is to detect the at least one AD capable CPE by way of the linetesting functionality associated with the AD enabled DSL linecard.
11. The apparatus according to claim 9 , wherein the network management module is to disable at least one channel associated with a POTS card and another at least one channel associated with a splitter after detection of the at least one AD capable CPE.
12. A method, comprising:
enabling an all digital loop (AD) mode associated with an AD enabled Digital Subscriber Line (DSL) linecard, the AD enabled DSL linecard is to process Internet Protocol (IP) telephony signals and DSL data signals in the AD mode, the IP telephony signals including at least Voice over IP (VoIP) signals;
disabling baseband legacy service support to at least one channel associated with at least one all digital loop (AD) capable Customer Premises Equipment (CPE); and
detecting CPE signature circuitry associated with the AD capable CPE, the CPE signature circuitry indicating compatibility with the AD mode of the AD enabled DSL linecard.
13. The method according to claim 12 , wherein the act of disabling includes disabling the baseband legacy service support on at least one channel associated with the AD enabled DSL linecard and disabling the baseband legacy service support on at least one channel associated with a POTS card.
14. The method according to claim 13 , wherein the act of disabling further includes disabling the baseband legacy service support on at least one channel associated with a splitter.
15. The method according to claim 12 , further comprising disabling at least one POTS card and at least one splitter after enabling the AD mode associated with the AD enabled DSL linecard.
16. The method according to claim 12 , wherein the act of detecting the CPE signature circuitry is performed by line testing functionality associated with the AD enabled DSL linecard or by line testing functionality associated with a POTS card.
