Page 11: Osd732 Operation
OSD732R, a conventional telephone circuit is established. If the handset connected to the OSD732T is in the "OFF HOOK" state, the trunk line at the OSD732R end is switched into its active state, thus informing the exchange that the handset is “OFF HOOK”. The exchange feeds a dial tone via the fiber modems to the handset so that the user can then dial the required number. -

In the case where Tip and Ring reversal is encountered at one end (eg OSD732R), the distant OSD732 (eg OSD732T) will transfer the polarity reversal over the fiber link providing system integrity. *Note: This feature is only available on units with serial numbers 10004506 and higher. -
