Description
Technical field
The present invention relates to network communication field, more specifically, relate to a kind of power failure alarm device and method, xDSL outdoor cabinet and xDSL system.
Background technology
Domestic numerous fixed telephone subscribers use digital subscriber line (DigitalSubscriber Line in a large number at present; XDSL) broadband access network technology, wherein, xDSL comprises adsl (asymmetric digital subscriber line) road (Asymmetric Digital Subscriber Line; ADSL) and VDSL road (Very-high-speed Digital Subscriber line; VDSL), be example with ADSL, each telecom operators has the family of general-purpose more than 8000.
Easy in order to describe, the present invention is that example describes with ADSL, hereinafter the explanation of ADSL is equally applicable to comprise all xDSL of VDSL.
Fig. 1 is the transmission sketch map of ADSL access technology in the prior art.
As shown in Figure 1; On up direction; Arrive local side main-frame (Main Distribution Frame through separator 111 mixed mixed signals (comprising) through indoor lead-in 114, junction box 115, distribution 116, cross-connecting box 117, trunk copper cable 118 from the high-frequency data signal component of user's ADSL Modem 112 with from the low frequency voice signal components of telephone set 113; MDF) 119; Receive terminal board 121 through wire jumper 120, terminal board 121 is received Digital Subscriber Line Access Multiplexer (Digital Subscriber Line Access Multiplexer, the DSLAM) separator board 124 of equipment 123 through cable 122; Directly be sent to DSLAM database 125 through separator board 124 isolated high-frequency data signal components, accomplish the demodulation of high-frequency data signal; Be sent to terminal board 127 through separator board 124 isolated low frequency voice signal components through cable 126; Through wire jumper 128 the low frequency voice signal components is delivered to terminal board 129, terminal board 129 is delivered to SPC telephone exchange 131 through cable 130 with the low frequency voice signal again.In addition, (Uninterruptible Power Supply, UPS) system 133 is 123 power supplies of local side DSLAM equipment by uninterrupted power supply through power line 132.
Along with becoming increasingly abundant of Internet network application; The applied more and more of Video chat, online request and high-speed downloads; The 1M downstream rate that operator offered the user in the past far can not satisfy user's demand, and the downloading rate of 8M even 16M becomes user's new demand gradually.The average download rate that present ADSL technology provides is 2M, and the access rate that how to improve ADSL is the hot issue that each big telecom operators is explored.The ADSL technology is come transmitting user data through the frequency band of 26KHz～2MHz, and available band is wide more, and the ADSL access rate is just high more.Because square being directly proportional of the decay of frequency band and line length, so along with the increase of distance between user's ADSL Modem and the local side DSLAM equipment makes the also increase gradually of decay of frequency band, thereby the reduction of user rate caused.At present in each medium-and-large-sized city; Local side DSLAM equipment arrives the range averaging of user's ADSL Modem about 3KM; Cause spendable downloading rate less than 4Mbps; In order to reach the downloading rate about 16Mbps, need be controlled at the distance of DSLAM equipment and user's ADSL Modem about 800 meters.At present the cross-connecting box of telecommunication system to the distance of user side all about 500 meters, so can improve user's access rate to the position that local side DSLAM equipment is advanced to cross-connecting box.
The reach of so-called local side DSLAM equipment is exactly to be installed in local side DSLAM equipment in the specific casing (can with this casing called after ADSL outdoor cabinet); And this casing is installed near the cross-connecting box, user's ADSL Modem just can be controlled in 800 meters to the distance of DSLAM equipment like this.
Fig. 2 is the transmission sketch map of the ADSL access technology after the reach of DSLAM equipment in the prior art.
As shown in Figure 2, the working method of the working method of ADSL outdoor cabinet and local side DSLAM equipment is similar.On up direction; Receive in the ADSL outdoor cabinet 214 through wiring line terminal board 212, interconnection 213 in indoor lead-in 114, junction box 115, distribution 116, cross-connecting box 211, the cross-connecting box 211 through separator 111 mixed mixed signals (comprising) from the high-frequency data signal component of user's ADSL Modem 112 with from the low frequency voice signal components of telephone set 113; Signal is after terminal board 215 switchings; Get into the separator board 124 in the DSLAM equipment 221; Be admitted to DSLAM database 125 through separator board 124 isolated high-frequency data signals, accomplish the demodulation of high-frequency data signal; Pass through terminal board 216 again through separator board 124 isolated low frequency voice signals; Send back to the basic routing line terminal board 218 of cross-connecting box 211 again through interconnection 217; The low frequency voice signal is delivered to the SPC telephone exchange 131 of remote end module office again through trunk copper cable 219, accomplish call function.In this system, civil power 220V alternating current is supplied with the DSLAM equipment 221 in the ADSL outdoor cabinet through power distribution system 220.In brief; The ADSL outdoor cabinet is through outdoor cabinet local side DSLAM equipment to be installed near the cross-connecting box; Operation principle does not have essential distinction; But can make the distance between DSLAM equipment and the user side shorten to 500 meters～800 meters greatly, thereby the downloading rate of 16Mbps～20Mbps can be provided for the user.
But DSLAM equipment in practical application in the ADSL outdoor cabinet and local side DSLAM equipment ensure on the performance that at power supply significant difference is but arranged.Local side DSLAM equipment has UPS and storage battery to carry out the power supply guarantee, and UPS has perfect power supply alarming system, thus local side DSLAM equipment seldom cut off the power supply, even and the outage also be very easy to find, the operation maintenance personnel are in time rushed to repair.But at present the ADSL outdoor cabinet is generally supplied power through introducing civilian civil power, and power supply can not get ensureing like this, and because ADSL outdoor cabinet space is very little, can't be equipped with storage battery, and if configuration storage battery then the price that makes ADSL outdoor cabinet costliness too.
For the access distance that makes most of user is controlled in 500 meters, telecom operators have built a large amount of ADSL outdoor cabinets at present, and the ADSL outdoor cabinet scale of a medium-sized city construction just can reach thousands of.Thousands of ADSL outdoor cabinets are scattered near each cross-connecting box in each city; After the DSLAM equipment in the ADSL outdoor cabinet loses management; Be difficult in time to pinpoint the problems, can not manage even find DSLAM equipment, also being difficult to distinguish is that the optical fiber of transmission usefulness break, or the power supply of DSLAM equipment has broken or the damage of the uplink plate of DSLAM equipment; To such an extent as to the operation maintenance personnel can not in time find, distinguish all kinds of obstacles, can't in time fix a breakdown thereby cause.And behind power fail recovery, can not learn this information in the very first time.
