70. 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, US
B 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 Unit
B. Mobile Satellite Union
C. Mobile Satellite Unit
D. 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 telephony
B. broadcast quality audio
C. file transfer and LAN routing
D. all of the above
(4) The channel between the mobile equipment and the satellite for mobile ISDN provides up to of bandwidth? ____
A. 4.8kbps
B. 9.6kbps
C. 64kbps
D. 128kbps
71. 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 stable
B. easy and expensive
C. easy and reliable
D. 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 RCC
B. enter the system gradually/contact a coast station
C. enter the system manually/contact with any CES
D. have absolute priority to enter the system/contact a CES
(3) The SES operator cannot set up communication through
a CES, _____ it’s within the same ocean region as the SES.
A. once
B. if
C. unless
D. when
(4) Which of the following acronyms has the different meaning for the sa me letter of “S”? _____
A. CES
B. SES
C. NCS

72. 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 immediately
B. not acknowledge the distress alert by DSC immediately
C. acknowledge the distress alert on MF or VHF channel
D. terminate the call

A. transmit the call
B. receive the call
C. stop the call
D. continue to receive the call
(3) Ships receiving a DSC distress alert should make
acknowledgement _____.
A. immediately
B. as soon as possible
C. after a short time
D. as late as possible
(4) What’s the main idea of the passage?_____
A. DSC distress alert transmission
B. DSC distress alert reception
