5.1.4.4 Test Functions
There are two types of monitoring/testing functions:
• Active tests which partly degrade the functionality (e.g. Payload Loop, Remote Loop,
• Diagnostics, during which the device is not operational (e.g. diagnostic loop of an
Payload Loopback
To perform an effective circuit test a line loop is implemented.
When the payload loopback (FMR2.PLB) is activated the received 192 bits of payload
data will be looped back to the transmit direction. The framing bits, CRC6 and DL bits are
not looped. They are originated by the FALC54 transmitter. When the PLB is enabled the
transmitter and the data on pins XL1/XDOP and XL2/XDON are clocked with SCLKR
instead of SCLKX. Data on pin XDI are ignored. All the received data are processed
normally. With bit FMR2.SAIS an AIS could be sent to the system interface via pin RDO.
