What Hardware Do I Need?
Caller Display 2 is supplied with a small Caller ID unit.
If you have two or more telephone lines and can use a Caller ID unit
on each line (up to 4). You will need a serial port card to provide the
extra ports for additional units. With the serial port card it is possible
to use Caller Display on the voice line while using a modem on the other
line to access the Internet or send a fax.
Caller ID Unit
The CID1 Caller ID unit may be used in place of a Pace modem to
decode Caller ID on incoming telephone calls. It plugs into a standard
telephone socket and passes Caller ID information on to the computer via
its serial port. A telephone splitter adapter is included so you can connect
a normal telephone to the same telephone socket.
The CID1 unit is BABT approved and is
powered from the computer's serial port. It has an REN (Ringer Equivalence
Number) of 0, so it can still be used even if your total REN is
already 4 (for example, if you have 4 telephone handsets on the
As well as logging and displaying details of incoming calls it
will log outgoing calls dialled from any telephone extension. Whenever
somebody dials out using an extension on the same line the telephone
number (and the name, if it is in the database) appears on the computer
All incoming and outgoing calls are timed so you can immediately
see how long each call lasted.
The system may be used with any modern Acorn computer, including
the Risc PC, A7000, A5000, A4000, A3020, A3010 and A4, and a PC
version is also available.
If the serial port is already used (perhaps for a modem) or if
you have an older Acorn computer, such as an A300 or A400 machine
you are advised to use an extra serial port card (available from
56k Voice Modem
Our RISC OS Caller Display software works with the Pace 56k voice modem.
Unfortunately these modems are no longer manufactured and we have sold
out, but CJE Micros
still have some left.
Note that this modem supports the BT Caller ID standard. Although many
other modems claim to offer Caller ID, most do not work on BT lines as
they are designed for the US market.
This modem works well with the ANT Internet suite using a driver which
we supply and also with Arcfax for sending and receiving faxes. Caller
Display works alongside these other programs so it will detect the incoming
Caller ID when you receive a call, but still allow Arcfax or InetSuite
to use the modem. Once they have finished Caller Display automatically
takes over again.
