Once your Inmarsat C or Mini C terminal has been installed and activated, it must first be logged in to an ocean region before it can send or receive messages.
Logging-in is managed via the NCS, a specially equipped LES, appointed as the NCS for a particular ocean region, which monitors and co-ordinates the operation of all the Inmarsat C and Mini C terminals and LESs within that ocean region.
Logging-in automatically tunes your terminal to the correct NCS Common Signalling Channel for that ocean region and informs the network that your Inmarsat C or Mini C terminal is available for communications.
Some Inmarsat C and Mini C models may automatically log in to the Inmarsat C network when first switched on, selecting the strongest NCS Common Channel signal if they are in an overlappinig satellite region.
Other models must be manually logged in to the selected ocean region or NCS.
After a few minutes your terminal should indicate that it has successfully logged in to the selected ocean region and also indicate signal strength received from the NCS. The signal strength should be at least the minimum required by the manufacturer. If not, refer to the manufacturer’s instructions on what action you should take.

D. A and B
48. what does NCS mean? A
A. NCS is abbreviated for Network Co-ordinating Station.
B. NCS is a specially equipped LES.
C. NCS monitors and co-ordinates the operation of all the Inmarsat C and Mini C terminals and LESs within its ocean region.
D. A, B, C are all right.
49. why should your Inmarsat-C MES be logged-in to the required ocean region before sending and receiving messages? D
A. the operation of log-in tunes your terminal to the correct NCS Common Signalling Channel for that ocean region.
B. the operation of log-in informs the network that your Inmarsat C or Mini C terminal is available for communications.
C. the operation of log-in is just a operating procedure.

The kbit/s data service supports applications between ISDN terminals using ISDN protocols such as V.120 or X.75. it will support any kbit/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 kbit/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 taken for granted in today’s office.

B. the number of characters being sent.
C. either the duration or the number of letters sent.
D. this passage does not tell us.
54. what kind of services is available through the Mobile ISDN? D
A. video conferencing and secure telephony
B. broadcast quality audio
C. file transfer and LAN routing
D. all of the above
55. the channel between the mobile equipment and the satellite for mobile ISDN provides up to of bandwitdth? C
A. 4.8kbps B. 9.6kbps C. kbps D. 128kbps
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.
56. it is quite _C___ for SES operator to send a distress alert.
A. difficult and stable B. easy and expensive
C. easy and reliable D. possible and compulsory
57. any ships with SES can _D__ and ___ through the Inmarsat satellites when sending a distress alert.

59. the shore Inmarsat user can only use __B__ .
A. a few CESs within his ocean region
B. that associated CES for a certain ocean region
C. a number of Ces insede and outside his area
