LINESHARE MASTER-4, LINESHARE RACK
When the line-sharing device
answers the call, it detects the
reverse modem tone from the
Lineshare Master-4 and routes the
call to the receiving modem. When
the receiving modem answers the
call, the Lineshare Master-4 detects
its carrier signal and releases the line
to the calling modem. The two
systems then establish their
communications link.
