Spectral compatible remote asymmetric digital subscriber line plus (ADSL+) deployment
View Patent ↗For ADSL+ deployment between a remote cabinet and customer premises, the upper part of the traditional ADSL downstream frequency band is used whereas the lower part of this trasitional ADSL downstream frequency band is switched off through spectral masking. This way, ADSL+ deployment from the remote cabinet is spectral compatible with ADSL deployment from the central office for a certain service capability wherein the upper part of the traditional ADSL downstream frequency band is switched off.
1. A method to deploy an Asymmetric Digital Subscriber Line Plus (ADSL+) service between a remote cabinet and at least one customer premises terminal, wherein for downstream data transfer a higher frequency spectrum than the traditional Asymmetric Digital Subscriber Line (ADSL) downstream frequency spectrum is used, the method comprising:
switching off a lower part of a traditional ADSL downstream frequency spectrum through spectral masking for downstream data transfer of the ADSL+ service;
wherein for said downstream data transfer of said ADSL+ service, an upper part of said traditional ADSL downstream frequency spectrum is also used.
2. The method to deploy ADSL+ according to claim 1 ,
wherein said upper part of said traditional ADSL downstream frequency spectrum corresponds to a frequency spectrum from a first frequency between 450 kHz and 500 kHz up to a second frequency being 1104 kHz.
3. A remote Digital Subscriber Line cabinet configured to provide to at least one customer an Asymmetric Digital Subscriber Line Plus (ADSL+) service wherein for downstream data transfer a higher frequency spectrum than a traditional Asymmetric Digital Subscriber Line (ADSL) downstream frequency spectrum is used,
said remote Digital Subscriber Line cabinet comprising spectral masking means for switching off a lower part of the traditional ADSL downstream frequency spectrum for said ADSL+ service, wherein said Digital Subscriber Line cabinet is further configured to use for said downstream data transfer also an upper part of said traditional ADSL downstream frequency spectrum.
4. A Digital Subscriber Line central office able to provide to at least one customer an Asymmetric Digital Subscriber Line (ADSL) service,
wherein said Digital Subscriber Line central office comprises spectral masking means for switching off an upper part of the traditional ADSL downstream frequency spectrum for said ADSL service.
5. A Digital Subscriber Line management hardware platform managing a number of Digital Subscriber Line nodes in a network comprising at least one Digital Subscriber Line central office able to provide an Asymmetric Digital Subscriber Line (ADSL) service, and at least one remote Digital Subscriber Line cabinet able to provide an Asymmetric Digital Subscriber Line Plus (ADSL+) service,
wherein said Digital Subscriber Line management hardware platform is configured to instruct said Digital Subscriber Line cabinet to switch off a lower part of a traditional ADSL downstream frequency spectrum through spectral masking for providing said ADSL+ service.
