Global Operation
Parallel Phone Detection
© 2007, Copeland Communications, Inc.
The CC-2401 provides a programmable line interface to meet international telephone line requirements. The
following table provides the register settings required to meet various country PTT standards.
The CC-2401 can detect when another telephone, modem or other device that is using the phone line. This
allows the hos t to avoid interrupting another phone call when the phone line is already in use and to
intelligently handle the interruption when the modem is using the phone line.
On-Hook Intrusion Detection
When the CC-2401 is sharing the telephone line with other devices, it is important that it not interrupt a call in
progress. To detect when another device is using a shared telephone line, the host can use the modem to
monitor the TIP-RING dc voltage with the LVS[7:0] bits (SDB). This register has a resolution of 1V per bit with
an accuracy of about ±10%. Bits 0 through 6 of the 8 bit signed 2’s complement number indicate the line
voltage value. Bit 7 indicates the polarity of TIP and RING.
When all devices on the phone line are on-hook, there is no loop current through TIP and RING. Therefore,
the voltage is at maximum. On most telephone lines, this is a minimum of 40V. When a device goes off-hook
the TIP-RING voltage drops. On most telephone lines, this off-hook voltage is a maximum of 20V.
