Your Versa-Link ATX-250 is compatible with virtually all
modern telecommunications equipment, including single
and multi-line telephones. Because your ATX-250 is
installed between your telephone system and the phone
company, it can direct all your telephone traffic to the
proper equipment. The most popular types of equipment
used with a Versa-Link ATX-250 are described below.
Your ATX-250 has special features that work extremely
well with FAX machines and PC FAX Boards. The Auto
FAX Detection feature allows most FAX calls to transfer to
your FAX machine automatically.
The vast majority of FAX machines sold today have the
ability to dial the number of the receiving FAX from
memory, and then identify itself as a FAX machine with a
tone (called CNG tone or AUTO-FAX tone). It will then
continue to identify itself until the called FAX answers the
call. When an ATX-250 is used at the receiving end, it can
detect this FAX identification tone, and automatically
transfer the call to the FAX machine on the receiving end,
without ringing the telephone.
Occasionally, calls will come from a FAX machine without
a FAX identification tone. This may happen if the calling
person is using an older FAX machine, or dials the number
manually using the FAX handset. In most applications,
calls without this auto-FAX tone will be routed to your
telephone system. The call can be manually transferred to
the FAX machine by dialing *2 (or another selected
code) on your telephone keypad. Either the caller or the
person who answers can transfer the call. See section
4.2.2 for details of operation.
If possible, ask people who send you FAX messages to
program your number into their FAX machine’s memory.
This will allow FAX calls to always be processed
automatically.
Your ATX-250 is compatible with all dial-up MODEMS. Usually, MODEMS are attached to the DEVICE 2 connector of your ATX-250. Your ATX-250 will transfer incoming calls to your MODEM when the calling MODEM dials *2 (or another code, if re-programmed) after the call has been answered by your Versa-Link. The data protection feature prevents interruptions from other telephone equipment.
If your MODEM is only used for out-bound communication,
you do not need to be concerned with the device selection code for the MODEM.The device selection code for your MODEM is best dialed by the calling MODEM. For example, when calling into a MODEM attached to DEVICE 2, with the ATX-250 factory programming, the dialing command for a Hayes compatible MODEM would be:
ATDT 1 203 555 1234 ,,,,*2
The commas will generate pauses in the dialing MODEM. The number of pauses may need to be changed to allow enough time’for the call to be switched through the telephone company, particularly if the calling MODEM is dialing long-distance. The selectable device codes can be reconfigured to add security to any system. Your ATX--250 will restrict access to only those callers who dial the right device selection code. See section 6, USER SELECTABLE FEATURES, to
change this code.
Some MODEMS cannot dial the * symbol. Therefore, if you plan to connect a computer MODEM, it is best to choose a device selection code for your computer that does not use the * symbol.
Your ATX-250 may be used with single and multi-line telephone equipment. Both tone-dialing and pulse-dialing equipment may be used with your ATX-250. See section 4.2.2 for restrictions when using pulse-dialing equipment.
Your ATX-250 is also compatible with Credit Authorization
Terminals, Electronic Mail Terminals, and Loop-Start dialup
TELEX machines.
Your ATX-250 can also be used with answering machines
and cordless phones.
Your ATX-250 is now programmed to wait for and detect the
transmission of "Caller ID" data. This function allows the calling
party’s phone number to appear on your "Caller ID" display unit
before your ATX-250 routes the call to any device.
