example 1

[0098] Example 1 (Physical Misdivision Using Time Division)

[0099] Figure 13 It is a schematic diagram of a system framework for realizing coexistence of POTS voice service and reverse power supply service on a twisted pair line by adopting a time-division physical misdivision method according to an embodiment of the present invention. Such as Figure 13 As shown, the POTS voice service and reverse power supply between the DPU of the access head-end device and the network adapter adopt the time dislocation method for physical dislocation, so as to realize the coexistence between POTS voice and reverse power supply. When the POTS voice of the system is working, the network adapter stops supplying power to the DPU access head-end equipment, and completes the voice service between the DPU and the POTS phone first, until the end of the POTS voice service, and then resumes the feedback to the DPU of the access head-end device. In this way, low-frequency signals such as POTS vo...

[0122] Example 2 (Physical Misdivision by Frequency Division)

[0123] Figure 16 It is a schematic diagram of a system framework for realizing coexistence of POTS voice service and reverse power supply service on a twisted pair line by adopting a frequency division physical misdivision method according to an embodiment of the present invention. Such as Figure 16 As shown, the POTS voice service and reverse power supply between the DPU of the access head-end device and the network adapter adopt the frequency dislocation method for physical dislocation work, and the network adapter and the DPU need to carry out information such as ringing and dialing through local communication Conversion to achieve coexistence between POTS voice and reverse power supply. When the POTS voice is working, the low-frequency information such as ringing and dialing of the POTS phone is converted between the head-end device DPU and the network adapter through the respective POTS voice adapters, us...

[0145] Example 3 (Physical wrong division by air separation method)

[0146] Figure 19 It is a schematic diagram of a system framework for realizing coexistence of POTS voice service and reverse power supply service on a twisted pair line by adopting a space division physical misdivision method according to an embodiment of the present invention. Such as Figure 19 As shown, when there are multiple pairs of reverse power supply between the DPU of the access head-end device and the user network adapter, the POTS voice service and reverse power supply between the two can be physically misdivided by using space separation to realize POTS Coexistence between voice and reverse power supply; POTS telephone service uses a dedicated pair of POTS voice twisted pair to communicate with the DPU, data service uses another twisted pair, and the user equipment end supplies reverse power to the DPU through the twisted pair for data services Wire. In this way, the coexistence between POTS...

Abstract

The present invention provides a service separation processing method and apparatus, a distributed point unit (DPU), a network adapter, and a service separation processing system. The method comprises the steps of determining a physical misclassification manner for service separation of a twisted pair between the DPU connected at an access network side and the network adapter at a user side, wherein the physical misclassification manner comprises at least one of the following: a time misclassification manner, a frequency misclassification manner, and a line space misclassification manner; and performing separation processing on a plain old telephone service (POTS) transmitted on the twisted pair and a reverse power supply service provided by a user device for the DPU according to the determined physical misclassification manner. In related technologies, the POTS transmitted on the twisted pair and the reverse power supply service provided by the user device for the DPU cannot coexist. Through adoption of the method, the problem in the related technologies is solved, so that the user experience is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a service isolation processing method and device, a distributed optical access point device (Distributed Point Unit, DPU for short), a network adapter and a service isolation processing system. Background technique [0002] With the gradual deepening of the current Fiber to the Home (FTTH) technology, the ability of domestic and foreign telecom operators to provide users with home bandwidth is also gradually improving, and they already have gigabit access to buildings and 100M access Ability. However, because the cost of FTTH home access is relatively high, and the cost of the last few hundred meters of home access accounts for the highest proportion of investment, this leads to a low return on investment and a long payback period for FTTH. Therefore, operators A variety of more economical and affordable fiber optic segmented home access methods are used for replacement. In or...
