Anolgue to digital modem thingy

[Birdy]

Anyone know if you can get an 'adapter' which allows someone who has a portable PC with an inbuilt modem to use his modem at offices where they have a digital phone network?

Cheers ears :)

I asked the Comms guy here and he said theres not a converter of any sorts and it depends on the Phone switch in use. If it's a Digital switch it will have provision for analogue lines aswell but you'll need have a seperate phone line run to your desk.

If your trying to do it sneakily :naughty: without getting your comms guys involved you could try and run it off a fax machine line on a splitter cable but some phone numbers may be barred and obviously whilst your dialled in in won't send and recieve faxes and peeps will become suspicious if your using it for hours at a time :E

Another option is ISDN but again the card in Phone switch will need to have this enabled if your switch is capable and then you can share the same line for normal calls and dial-in.

I'm not an expect on telecoms but if its anything like our phone system then no.

As far as I can understand talking to our telecoms people the phones work on a sort of ISDN connection to the main phone switch.

And as far I know there are no analog to ISDN 'atapters'

As u can expect the digital switch will not like the screaming crap that comes out of an analog modem :)


But in world of telecoms I am often wrong, someone correct me? heh

Some1 go there 1st

Thats sort of the same as what I said? :D

At my college we have digital telephones, and the phones plug into the same rj45 conection plugs on the wall that the pc's use, presumably there is diferent wiring behind the wall box. Anyway staff who wanted to keep there old analogue telephones could as they have these analogue to digital converters, which u plug into the digital phone socket and give u a analogue one, which the modem could use. Now if u were asking the other way around (i don't think you were) yes i think it can be done with isdn modems that support analogue phone lines, or alterantively look at the option of having the line upgraded to isdn at the company exchange(surely you can think of some legit reason for it). I don't think this is a special situation..they had the same thing at where i did work experiance!

Hope this helps...btw the digital to analogue converters are a digital plug with a short wire going to a box like a matchbox with a analogue socket in it.

Boycee, the box your talking about merely converts the relavent wires from an RJ45 floor box into a analogue standard phone socket so you can plug the phone into it, we have the same although smaller by the sounds of it boxes at work, the Switch at the companies exchange is where it needs to be changed.

[Boycee]

Oh...sorry...but i thought that it must be as the wires from the floor boxes run through the 3com switches that the pcs do....although different coloured wores....presumabely so they can be identified? Surely this mean that data is digital...but the phone is analouge?


Sorry is i confused any1!

[Calzor Suzay]

Theres two options :)

The phones plug into the RJ45 boxes then at the rack where all the cables come together the phone ones go off to the exchange and the PC ones go off on there merry route to the hub/switches or...

Your running VOIP (Voice over IP) at your place where the telephone is routed via special switches that are capable of this, we use Cisco at work but 3com do an equivalent box (for probably half the price too :) ) although this is still farly expensive.

Yeah i do like the Cisco series 2500 routers :naughty:
