Figure 212: RFP channel occupation report - 6-channel RFP
The report indicates the following:
•
6 channels were free for 417 seconds. Therefore, at least 1 channel was occupied for
483 seconds (900 - 417 = 483 seconds).
• 5 channels were free for 302 seconds. Therefore, at least 2 channels were occupied for
181 seconds (483 - 302 = 181 seconds).
• 4 channels were free for 139 seconds. Therefore, at least 3 channels were occupied for
42 seconds (181 - 139 = 42 seconds).
• 3 channels were free for 37 seconds. Therefore, at least 4 channels were occupied for 5
seconds (42 - 37 = 5 seconds).
• 2 channels were free for 2 seconds. Therefore, at least 5 channels were occupied for 3
seconds (5 - 2 = 3 seconds).
• 1 channel was free for 0 seconds. Therefore, at least 1 channel was free at any
moment.
S-channel occupation
The backbone bus of a DECT system is the interface between the DMC boards. The DMC
boards communicate through the bus for the re-routing of calls.
A PP can be synchronized with an RFP that is not connected to the DMC board that contains
the subscription information for this PP. The DMC board to which this RFP is connected is
called the visitor DMC. The DMC board that contains the subscription information is called the
home DMC. The (visitor) DMC board to which the PP is locked (or synchronized) re-routes the
PP to the home DMC board.
The DMC board has 32 internal channels between the PRI block and the RFP interfaces. These
channels are named S-channels (see
Figure 213: Channels within the system on page 305
).
