The 64 kbit/s data service supports applications between ISDN terminals using ISDN protocols such as V.120 or X.75. it will support any 64kbit/s data stream and is the service used for implementing ISDN applications such as video conferencing, LAN routing, file transfer, broadcast- quality audio transmission and secure telephone.The service is accessed primarily through the RJ-45 connector on the Mobile Satellite Unit. Multiple ISDN devices (up to eight) can be attached to the MSU.A point-to-point protocol (PPP) modem data service, suitable for file transfer, e-mail or internet access, may also be available via an RS-232 interface, USB port or infrared port.With Inmarsat Mobile ISDN, the customer uses a dedicated line or channel between the mobile equipment and the satellite. This channel provides up to 64kbit/s of bandwidth. Users are charged by the length of time this dedicated channel is allocated. Because of the global growth of ISDN, a whole arrange of telecommunications applications that were once the domain of large corporations have now become cost-effectively available to even the smallest of businesses. Dial-up networking using ISDN enables any number of Local Area Networks (LANs) to be quickly and easily linked. Other services available through the Mobile ISDN are video conferencing and broadcast-quality audio.An ISDN call typically takes less than five seconds to connect, which is something to take into account when the call is over a satellite communications system. With the introduction of the Inmarsat Mobile ISDN service, there is no longer any reason why people working in remote locations should not enjoy the sophisticated IT solutions that are t aken for granted in today’s office.(1) What does MSU mean? _____A. Maritime safety UnitB. Mobile Satellite UnionC. Mobile Satellite UnitD. Marine Security Union(2) Users are charged by _____ for the Inmarsat mobile ISDN 64kbps service?A. the length of time the dedicated channel is allocated.B. the number of characters being sent.C. either the duration or the number of letters sent.D. this passage does not tell us.(3) What kind of services is available through the Mobile ISDN? ____A. video conferencing and secure telephonyB. broadcast quality audioC. file transfer and LAN routingD. all of the above(4) The channel between the mobile equipment and the satellite for mobile ISDN provides up to of bandwidth? ____A. 4.8kbpsB. 9.6kbpsC. 64kbpsD. 128kbps71. For ships equipped with an Inmarsat SES, sending a distress alert is both simple and certain. It only involves pressing a special distress button or using an abbreviated dialing code. This automatically gives priority access to the system and establishes contact with a CES via the Inmarsat satellite.The SES operator can choose the most suitable CES for the communication service required, as long as the CES is within the same ocean region as the SES. The shore Inmarsat user does not have the flexibility and is limited to using the CES through which his local PTT administration has a routing agreement for a particular ocean region.(1) It is quite _____ for SES operator to send a distress alert.A. difficult and stableB. easy and expensiveC. easy and reliableD. possible and compulsory(2) Any ships with SES can ____ and ___ through the Inmarsat satellites when sending a distress alert.A. establish contact with the system/contact with RCCB. enter the system gradually/contact a coast stationC. enter the system manually/contact with any CESD. have absolute priority to enter the system/contact a CES(3) The SES operator cannot set up communication througha CES, _____ it’s within the same ocean region as the SES.A. onceB. ifC. unlessD. when(4) Which of the following acronyms has the different meaning for the sa me letter of “S”? _____A. CESB. SESC. NCSD. MSI72. Ships receiving a DSC distress alert from another ship should normally not acknowledge the distress alert by DSC since acknowledgement of a DSC distress alert by use of DSC is normally made by coast stations only.If a ship station continues to receive a DSC distress alert on an MF or VHF channel, a DSC acknowledgement should be transmitted to terminate the call only after consulting with a RCC or a coast station and being directed to do so.Ships receiving a DSC distress alert from another ship also defer the acknowledgement of the distress alert by radiotelephony for a short interval, if the ship is within an area covered by one or more coast stations, in order to give the coast station time to acknowledge the DSC distress alert first.(1) Any ship should____ after receiving a DSC distress alert from another ship.A. acknowledge the distress alert by DSC immediatelyB. not acknowledge the distress alert by DSC immediatelyC. acknowledge the distress alert on MF or VHF channelD. terminate the call(2) Ships receiving a DSC distress alert may ____ after getting permission from RCC.A. transmit the callB. receive the callC. stop the callD. continue to receive the call(3) Ships receiving a DSC distress alert should makeacknowledgement _____.A. immediatelyB. as soon as possibleC. after a short timeD. as late as possible(4) What’s the main idea of the passage?_____A.

distress message should be preceded by :A: PAN PANB: SECURITEC: MAYDAYD: MEDICO三、阅读理解PASSAGE1:The IMO also introduced digital selective calling (DSC) on VHF, MF and HF maritime radios as part of the GMDSS system: DSC is primarily intended to initiate ship/ship, ship/shore, and shore/ship radiotelephone and MF/HF radiotelex calls: DSC calls can also be made to individual ships or groups of ships: DSC distress alerts, which consist of a preformatted distress message, are used initiate emergency communications with ships and rescue coordination centers: When fully implemented, DSC will eliminate the need for persons on a ship's bridge or on shore to continuously guard radio receivers on voice radio channels, including VHF channel 16 (156:8 MHz) and 2182 kHz now used for distress, safety and calling: A listening watch aboard GMDSS-equipped ships on 2182 kHz ended on 1 February 1999, and on VHF channel 16 is scheduled to end on 1 February 2005: We urgethat the DSC-equipped VHF and MF/HF radios be externally connected to a satellite navigation receiver: That connection will ensure accurate location information is sent to a rescue coordination center if a distress alert is ever transmitted: FCC regulations actually require that ship's position be manually entered into the radio every four hours on ships required to carry GMDSS equipment, while that ship is underway (47 CFR 80:1073): Once SOLAS ships are allowed to disband watch-keeping on VHF and MF radiotelephone channels, other ships are going to need DSC-equipped radios to contact these ships,particularly in a passing situation, especially when outside U:S:waters: We believe VHF, MF and HF radiotelephone equipment carried on ships should include a DSC capability as a matter of safety: To achieve this, the FCC requires that all new VHF and MF/HF maritime radiotelephones type accepted after June 1999 to have at least a basic DSC capability: VHF digital selective calling also has other capabilities beyond those required for the GMDSS: The Coast Guard uses this system to track vessels in Prince William Sound, Alaska, Vessel Traffic Service: IMO and the USCG also plan to require ships carry a Universal Automatic Identification System, which will be DSC-compatible: Countries having a GMDSS A1 Area will be able to identify and track AIS(自动识别系统)-equipped vessels in its waters without any additional radio equipment:1、Which of the following is the best answering?A: Only VHF equipment can used DSC:B: Only MF equipment can used DSCC: Only HF equipment can used DSC:D: DSC will use on VHF, MF and HF equipment2、According to this message, which of the following is wrongA: When fully implemented, for persons to continuously guard will eliminateB: DSC is used for watchingC: DSC is only used for watching:D: DSC is used to initiate emergency communication:3、According to this message, the watch-keeping of VHF CH16 will be ended _______:A: on 1 February 1999:B: on 1 February 2005:C: on 1 February 2000:D: on 1 February 2010:4、The writer intends that the VHF/MF/HF radio equipment _______:A:should have its own satellite navigator;B:have nothing to do with the satellite navigation system;C:should be connected to a satellite navigator:D:should change the ship’s position manually every hours:5、Which statement is not correct?A:DSC can initiate radio-telephone and radiotelex calls onVHF/MF/HF bands:B:DSC can initiate radio-telephone calls on VHF/MF/HF bands:C:DSC can initiate radiotelex calls on MF/HF bands:D:DSC can initiate VHF/MF/HF radio-telephone and MF/HF radiotelex calls:6、The AIS equipment will be used to ________:A:identify and track vessels in A1sea area;B: identify and track vessels in A2sea area;C:identify and track vessels in A3sea area;D:identify and track vessels in A4sea area:7、The meaning of word “radios” in the passage is :A: radio equipmentsB: radio wavesC: radio programsD: no meaningPassage2.Satellite systems operated by the International Mobile Satellite Organization (Inmarsat), are also important elements of the GMDSS: Three types of Inmarsat ship earth station terminals are recognized by the GMDSS: the Inmarsat A, B and C: The Inmarsat A and B, an updated version of the A, provide ship/shore, ship/ship and shore/ship telephone, telex and high-speed data services, including a distress priority telephone and telex service to and from rescue coordination centers: The Inmarsat C provides ship/shore, shore/ship and ship/ship store-and-forward data and telex messaging, the capability for sending preformatted distress messages to a rescue coordination center, and the SafetyNET service: The Inmarsat C SafetyNET service is a satellite-based worldwide maritime safety information broadcast service of high seas weather warnings, NAVAREA navigational warnings, radionavigation warnings, ice reports and warnings generated by the USCG-conducted International Ice Patrol, and other similar information not provided by NAVTEX: SafetyNET works similarly to NAVTEX in areas outside NAVTEX coverage: Inmarsat C equipment is relatively small and lightweight, and costs much less than an Inmarsat A or B: Inmarsat A and B ship earth stations require relatively large gyro-stabilized antennas; the antenna size of the Inmarsat C is much smaller: Inmarsat also operates an EPIRB system, the Inmarsat L, which is similar to that operated by COSPAS-SARSAT:Under a cooperative agreement with the National Oceanic and Atmospheric Administration (NOAA), combined meteorological observations and AMVER reports can now be sent to both the USCG AMVER Center, and NOAA, using an Inmarsat C ship earth earth station, at no charge: There is also no charge to register for this service and to receive the necessary Inmarsat C software: For more information, see the NOAA Shipboard Environmental (data) Acquisition System, or SEAS: We strongly urge that Inmarsat C equipment have an integral satellite navigation receiver, or be externally connected to a satellite navigation receiver: That connection will ensure accurate location information to be sent to a rescue coordination center if a distress alert is ever transmitted:1、According to the passage, which type of Inmarsat SES terminals are approved by the GMDSS?A:INMARSAT-C;B:INMARSAT-M;C:INMARSAT MINI-M;D:INMARSAT-P2、The writer suggests that INMARSAT-C ship earth stations ______A:should have an satellite navigator;B:should be connected to a satellite navigation receiverC:A & BD:A or B3、The SafetyNET (satellite-based worldwide maritime safety information broadcast service) service is provided by _____________A:INMARSAT-AsystemB:INMARSAT-B systemC:INMARSAT-C systemD:INMARSAT-M system4、Which ship earth station does not requires relatively large gyro-stabilized antenna?A:INMARSAT-AB:INMARSAT-BC:INMARSAT-CD:Both A & B5、The meaning of phrase “store-and-forward” in the passage isA: first memorize, then relayB: memorizing messageC: directly send messageD: store a file6、INMARSAT-L isA: INMARSAT-C systemB: INMARSAT-BC: EPIRB system of INMARSATD: COSPAS-SARSAT7、According to the passage, which of the following is not true?A: a meteorological observation can be transmited to NOAA with Inmarsat-C SES at free of chargeB: A AMVER reports can be transmited to the USCG AMVER Center at chargeC: It is no charge to register for AMVER serviceD: It is no charge to receive Inmarsat-C softwarePassage3.The GMDSS installation on ships include one or more search and rescue radar transponders (SART), devices which are used tolocate survival craft or distressed vessels by creating a series of dots on a rescuing ship's 3 cm radar display: The detection range between these devices and ships, dependent upon the height of theship's radar mast and the height of the SART, is normally about eight nautical miles: Note that a marine radar may not detect a SART even within this distance, if the radar settings are not optimized for SART detection1、Which statement is true according to the passage?A:SART can send alert signals to RCC through INMARSAT system;B:SART can send alert signals to RCC through COSPAS-SARSAT system;C:SART can send alert signals to RCC through VHF/HF/MF communication system;D:SART is used to locate survival craft or distressed vessels2、The detected distance of SART is determined by_________A、The position of the SARTB、The frequency of the marine radarC、The height of the radar antenna and the SARTD、The frequency of the SART3、If the radar settings are not optimized for SART detection，maybeA、 can not see returns of SART on radar screenB、 can see returns of SART on radar screenC、 affect function of SARTD、 be independent of radar detectingPassage4.Radar should not be regarded as more than an aid to the detection of other vessel, and collisions in poor visibility can be averted for certain only if the information provided by the radar set is correctly interpreted。

:A: PAN PANB: SECURITEC: MAYDAYD: MEDICO三、阅读理解PASSAGE1:The IMO also introduced digital selective calling (DSC) on VHF, MF and HF maritime radios as part of the GMDSS system: DSC is primarily intended to initiate ship/ship, ship/shore, and shore/ship radiotelephone and MF/HF radiotelex calls: DSC calls can also be made to individual ships or groups of ships: DSC distress alerts, which consist of a preformatted distress message, are used initiate emergency communications with ships and rescue coordination centers: When fully implemented, DSC will eliminate the need for persons on a ship's bridge or on shore to continuously guard radio receivers on voice radio channels, including VHF channel 16 (156:8 MHz) and 2182 kHz now used for distress, safety and calling: A listening watch aboard GMDSS-equipped ships on 2182 kHz ended on 1 February 1999, and on VHF channel 16 is scheduled to end on 1 February 2005: We urge that the DSC-equipped VHF and MF/HF radios be externally connected to a satellite navigation receiver: That connection will ensure accurate location information is sent to a rescue coordination center if a distress alert is ever transmitted: FCC regulations actually require that ship's position be manually entered into the radio every four hours on ships required to carry GMDSS equipment, while that ship is underway (47 CFR 80:1073): Once SOLAS ships are allowed to disband watch-keeping on VHF and MF radiotelephone channels, other ships are going to need DSC-equipped radios to contact these ships, particularly in a passing situation, especially when outside U:S: waters: We believe VHF, MF and HF radiotelephone equipment carried on ships should include a DSC capability as a matter of safety: To achieve this, the FCC requires that all new VHF and MF/HF maritime radiotelephones type accepted after June 1999 to have at least a basic DSC capability: VHF digital selective calling also has other capabilities beyond those required for the GMDSS: The Coast Guard uses this system to track vessels in Prince William Sound, Alaska, Vessel Traffic Service: IMO and the USCG also plan to require ships carry a Universal Automatic Identification System, which will be DSC-compatible: Countries having a GMDSS A1 Area will be able to identify and track AIS(自动识别系统)-equipped vessels in its waters without any additional radio equipment:1、Which of the following is the best answering?A: Only VHF equipment can used DSC:C: Only HF equipment can used DSC:D: DSC will use on VHF, MF and HF equipment2、According to this message, which of the following is wrongA: When fully implemented, for persons to continuously guard will eliminateB: DSC is used for watchingC: DSC is only used for watching:D: DSC is used to initiate emergency communication:3、According to this message, the watch-keeping of VHF CH16 will be ended _______:A: on 1 February 1999:B: on 1 February 2005:C: on 1 February 2000:D: on 1 February 2010:4、The writer intends that the VHF/MF/HF radio equipment _______:A:should have its own satellite navigator;B:have nothing to do with the satellite navigation system;C:should be connected to a satellite navigator:D:should change the ship’s position manually every hours:5、Which statement is not correct?A:DSC can initiate radio-telephone and radiotelex calls on VHF/MF/HF bands:B:DSC can initiate radio-telephone calls on VHF/MF/HF bands:C:DSC can initiate radiotelex calls on MF/HF bands:D:DSC can initiate VHF/MF/HF radio-telephone and MF/HF radiotelex calls:6、The AIS equipment will be used to ________:A:identify and track vessels in A1sea area;B: identify and track vessels in A2sea area;C:identify and track vessels in A3sea area;D:identify and track vessels in A4sea area:7、The meaning of word “radios” in the passage is :A: radio equipmentsB: radio wavesC: radio programsD: no meaningPassage2.Satellite systems operated by the International Mobile Satellite Organization (Inmarsat), are also important elements of the GMDSS: Three types of Inmarsat ship earth station terminals are recognized by the GMDSS: the Inmarsat A, B and C: The Inmarsat A and B, an updated version of the A, provide ship/shore, ship/ship and shore/ship telephone, telex and high-speed data services, including a distress priority telephone and telex service to and from rescue coordination centers: The Inmarsat C provides ship/shore, shore/ship and ship/ship store-and-forward data and telex messaging, the capability for sending preformatted distress messages to a rescue coordination center, and the SafetyNET service: The Inmarsat C SafetyNET service is a satellite-based worldwide maritime safety information broadcast service of high seas weather warnings, NA V AREA navigational warnings, radionavigation warnings, ice reports and warnings generated by the USCG-conducted International Ice Patrol, and other similar information not provided by NA VTEX: SafetyNET works similarly to NA VTEX in areas outside NA VTEX coverage: Inmarsat C equipment is relatively small and lightweight, and costs much less than an Inmarsat A or B: Inmarsat A and B ship earth stations require relatively large gyro-stabilized antennas; the antenna size of the Inmarsat C is much smaller: Inmarsat also operates an EPIRB system, the Inmarsat L, which is similar to that operated by COSPAS-SARSAT: Under acooperative agreement with the National Oceanic and Atmospheric Administration (NOAA), combined meteorological observations and AMVER reports can now be sent to both the USCG AMVER Center, and NOAA, using an Inmarsat C ship earth earth station, at no charge: There is also no charge to register for this service and to receive the necessary Inmarsat C software: For more information, see the NOAA Shipboard Environmental (data) Acquisition System, or SEAS: We strongly urge that Inmarsat C equipment have an integral satellite navigation receiver, or be externally connected to a satellite navigation receiver: That connection will ensure accurate location information to be sent to a rescue coordination center if a distress alert is ever transmitted:1、According to the passage, which type of Inmarsat SES terminals are approved by the GMDSS?A:INMARSAT-C;B:INMARSAT-M;C:INMARSAT MINI-M;D:INMARSAT-P2、The writer suggests that INMARSAT-C ship earth stations ______A:should have an satellite navigator;B:should be connected to a satellite navigation receiverC:A & BD:A or B3、The SafetyNET (satellite-based worldwide maritime safety information broadcast service) service is provided by _____________A:INMARSAT-AsystemB:INMARSAT-B systemC:INMARSAT-C systemD:INMARSAT-M system4、Which ship earth station does not requires relatively large gyro-stabilized antenna?A:INMARSAT-AB:INMARSAT-BC:INMARSAT-CD:Both A & B5、The meaning of phrase “store-and-forward” in the passage isA: first memorize, then relayB: memorizing messageC: directly send messageD: store a file6、INMARSAT-L isA: INMARSAT-C systemB: INMARSAT-BC: EPIRB system of INMARSATD: COSPAS-SARSAT7、According to the passage, which of the following is not true?A: a meteorological observation can be transmited to NOAA with Inmarsat-C SES at free of chargeB: A AMVER reports can be transmited to the USCG AMVER Center at chargeC: It is no charge to register for AMVER serviceD: It is no charge to receive Inmarsat-C softwarePassage3.The GMDSS installation on ships include one or more search and rescue radar transponders (SART), devices which are used to locate survival craft or distressed vessels by creating a series of dots on a rescuing ship's 3 cm radar display: The detection range between these devices and ships, dependent upon the height of the ship's radar mast and the height of the SART, is normally about eight nautical miles: Note that a marine radar may not detect a SART even within this distance, if the radar settings are not optimized for SART detection1、Which statement is true according to the passage?A:SART can send alert signals to RCC through INMARSAT system;B:SART can send alert signals to RCC through COSPAS-SARSAT system;C:SART can send alert signals to RCC through VHF/HF/MF communication system;D:SART is used to locate survival craft or distressed vessels2、The detected distance of SART is determined by_________A、The position of the SARTB、The frequency of the marine radarC、The height of the radar antenna and the SARTD、The frequency of the SART3、If the radar settings are not optimized for SART detection，maybeA、can not see returns of SART on radar screenB、can see returns of SART on radar screenC、affect function of SARTD、be independent of radar detectingPassage4.Radar should not be regarded as more than an aid to the detection of other vessel, and collisions in poor visibility can be averted for certain only if the information provided by the radar set is correctly interpreted。
