Teltone m-392 Guida Utente

Occasionally, a need to set a maximum off-hook time is required. The LSS allows either
no limit or a programmable maximum time of up to 255 minutes per port. After an off-hook
timeout timer expires, the device connected to the port will be sent a forced disconnect
(COD) and the C.O. line will be placed on-hook. This off-hook timeout should be set to
encompass the expected duration of any polling or other call.

When Privacy Timeout is enabled, any port remaining off-hook without dialing or
disconnecting properly, the LSS will connect the device to local battery feed and place the
incoming central office line on-hook to enable other ports to receive calls. This lockout of
an offending port occurs after first detecting

at least five seconds of Central Office dial

tone or two cycles of either busy or reorder tone during the first 15 seconds of off-hook,
and no DTMF digits and 5 or fewer rotary breaks dialed in 60 seconds.

If dial tone, busy, or reorder were not detected, or dialing was detected, the LSS will
monitor for either a hook-flash or forced disconnect. If a hook-flash or forced disconnect is
then detected, the LSS will re-start the privacy timeout period. No tones are sent to the
off-hook phone. Incoming calls to other ports (transfer code received from the Polling
Controller) are routed appropriately; calls to the off-hook privacy phone are given busy
tone.

If the port is returned to on-hook and then goes off-hook later, it will receive central office
dial tone per normal operation.
