FREELINK
telephone line simulators link two analogue
dial-up devices (for example modems or telephones)
without using real lines. This allows free
and easy local links for live operation
or training, demonstration, development,
maintenance etc. Fully automatic at all
line speeds, they allow either pulse or
tone dialling, or dial-free instant connection.
The Demo supports two devices. Fully bi-directional,
it is ideal for general modem, fax or phone
operation. When a device comes "off-hook"
it gets a dial-tone and can dial any number;
the other socket then rings automatically
and if it is answered, the devices are connected
for speech or data until they both ring
off. UK versions give a UK style "double"
ring pattern.
The Lite also supports two devices but has
uni-directional connection designed for
setting up and local links to voice processing
systems. Disconnection between calls allows
instant system resets, and while its "ring
per second" pattern ensures a quick
response, the audio option (if fitted) also
allows slow rings. With its neat one-piece
design, this is the clear choice where single-channel
auto-answer is required and only one socket
needs to ring. The Octal supports eight
devices linked as four independent pairs.
Each pair works exactly like the unidirectional
Lite. This makes it ideal for multiple one-way
connections for voice processing, exhibitions
and training. The Octet also has eight lines
in four pairs. None of the lines rings but
each socket is dead unless its partner is
off-hook which means line-sensing software
can answer instantly when a hand set is
lifted and reset when it is replaced. This
is ideal for all multiple links to line-sensing
devices such as voice modem systems, and
is fully bi-directional.
