Which cable connector type commonly supports both digital and analog video signals?
Both common 'TV Coax' and 'Type F' cable connectors are commonly used to support both digital and analog video signals.
Plain TV coax connectors (male and female) can easily be taken apart by anyone without having to use any tools, so they are commonly used for making simple cable connections for tv antennas and digital tv set-top boxes.
Type F (male and female) connectors use screw threads so that, by using simple tools such as wrenches and/or hand pliers, they can be tightened-up too hard to be loosened and disconnected by hand.
That is why Type F connectors are regularly used for making signal connections for cable and satellite tv systems and for computer broadband cable systems.

MSISDN is a number uniquely identifying a subscription in a GSM or UMTS mobile network. Simply put, it is the telephone number to the SIM card in a mobile/cellular phone. The abbreviation has several interpretations, most common one being "Mobile Subscriber Integrated Services Digital Network Number".[1] The MSISDN together with IMSI are two important numbers used to identify a mobile phone. IMSI is often used as a key in the HLR ("subscriber database") and MSISDN is the number normally dialed to connect a call to the mobile phone. The MSISDN follows the numbering plan defined in the ITU-T recommendation E.164. More Details in http://en.wikipedia.org/wiki/MSISDN

Can you transmit data ex GPS information or video over a two way radio if so how?
Data . . . Yes. You can use a 2-way (land mobile) radio to convey information in
digital form. In fact, most modern 2-way (LMR) systems carry the voices in the
form of digital data.
Video . . . In principle, video can be carried over a 2-way radio, but you wouldn't
like what you see. 2-way radio is a narrow-band communication channel, so any
information has to be sent over it rather slowly. For video, that means slow-scan
and low-resolution pictures. Ham radio operators do it, but you'd get tired of it.
GPS . . . Sure. The GPS data comes down from the satellites rather slowly, and
after it's detected and massaged by a GPS receiver, it can easily be carried to
another place over a land-mobile-radio link. But all that would tell you is the
location of the GPS receiver, i.e. the 2-way radio that sends it, which you would
probably already know. It wouldn't tell you anything about the location of the
2-way receiver where you're hearing it.
How the mobile service providers know whether the mobile is switched off or out of coverage?
Normally, when you have coverage and your phone is on, your phone regularly sends a "ping", or small signal telling the provider that your phone is on and can receive calls.When you turn your phone off, your phone sends a signal to your provider notifying them that your phone is off. When you lose coverage, your provider notices that it is not receiving pings from you and it did not receive the power-off signal.

Not so true. Search Wiki for more information on the origins of Mobile Phones. In fact, I've found reference that Neiman Marcus offered a telephone in the 1971 Ford Thunderbird. Still looking for information on how much they cost. -- Mark
