User's Manual 30. Analog Gateway
Version 6.8 503 Mediant 500L MSBR
The "start dial" signal is a wink from the PBX to the FXO device. The FXO then sends the
last four to five DTMF digits of the called number. The PBX uses these digits to complete
the routing directly to an internal station (telephone or equivalent).
DID Wink can be used for connection to EIA/TIA-464B DID Loop Start lines
Both FXO (detection) and FXS (generation) are supported
