That is the short answer -- but it is a very misleading one... As you point out, the difference in carrier (900MHz vs 1.9GHz) and other air interface is important. However, the difference between MAP / IS41 only matters at the higher protocol layers. To be simplisitic 'digits is digits' and so long as a base station contains a Layer 2 protocol that can detect the type of call and process it according to the right menu of algorithms, then why is there a problem? Detect which call it is, select the software, translate as required -- and BINGO ! rupert ------------------------------ Date: Wed, 21 Dec 1994 09:45:14 -0500 From: william pechter ILEX Subject: Re: The Bandwidth Tidal Wave by George Gilder Organization: Army Stars Demonstration Project, Ft.

If I have call waiting, I can prefix my call with *70 to cancel call waiting for my phone for the duration of the call. If I want to call a friend who also has call waiting using my modem so that his modem will pick up, is there some way to disable call waiting for both parties so that the modems will not be interrupted? Thanks, Jim [TELECOM Digest Editor's Note: It all depends. Assuming you have the permission of the person (whose modem) you are calling to make such a change, and assuming that person's phone line has both the ability to disable call waiting and *disable it after a call has been received* then yes, it can be done. Normally disabling call waiting has to be done before a call is placed, in the process of dialing the number. In some central offices, if the subscriber has three-way calling (thus giving him a valid reason for flashing the hook once a call is in progress) that hook flash can be used to dial a stand-alone *70 and automatically return to the call in progress with call waiting disabled for the duration of the call. The trouble comes up between modems. If his modem answers yours, then any flash of the hook afterward is going to put you on hold, cause a loss of carrier and the connection to be dropped, your modem making the assumption there was no answer, or the call was finished or whatever. So, he has got to do some funny business *before* his modem answers your call. He cannot just have the modem answer, send carrier, flash and leave the line momentarily. *If* (big if!) he can flash the hook in the middle of a call to do *70, then what he has to do is when the phone rings, take it off hook, pause about two seconds, flash the hook, dial *70, get returned to the call in progress (yours) then tell the modem ATA, that is, to go off hook in answer mode. Meanwhile, your modem has been sitting there patiently waiting for an answer. Now what if he is not home, or you want to do all this automatically? Well ... he is going to need to write a string for the modem which tells it to indeed answer, but not send carrier right away; to answer but pause a couple seconds, do a switchhook flash, dial *70, pause a couple seconds, then do ATA. An alternative is if you can get your modem to stand by and not drop carrier for an extended period of time. One of the S-registers can probably be set to a very high value (like 255) which will cause your modem to tolerate a very long loss of carrier for the few seconds he is going to have you on hold. If that can be done, then he can answer you normally and have his computer send you a little message saying 'please hold on' or something to that effect. His computer sends his modem a string to get its attention *while not getting the attention of your modem in the process*, flash, dial *70, do ATO or whatever to return to the connection in progress. Now and again people ask here how to make call waiting and modems compatible. The simple answer is you cannot. Yes, there are various ways to gerry-rig the whole thing with limited success. Better though, that you both bite the bullet and go with the accepted rule of thumb in data communications: *a dedicated line for the modem*, with no custom calling features on that line, except maybe Caller-ID if you see a need for it, or perhaps speed dialing, etc. PAT] ------------------------------ End of TELECOM Digest V14 #466 ******************************
