2. Three Units on the
Same Run
3. Using Optional Power Supplies
On normal incoming calls the TMS-RDMA will display the line to be answered and provide standard cadence tone burst. This ring
represents the incoming call before the call has been answered by the TMS-6X or the TMS-12A. In instances where one or more
lines have been answered by the TMS-6X or the TMS-12A, a double tone burst will sound. The digital display will then indicate the
next line to answer.
