AMT-70/AMT-73/AMT-75 Installation and Operation
6.1.7.3 3*HSSI Interface
With this interface installed, the aggregate data rates for all 3 channels are computed automatically.
Thus, it is not possible to change data rates using TDATA/RDATA commands.
Figure 43: 3*HSSI Commands Summary
Interface
Commands
hssi Used for setting HSSI channel data rates, clock inversion, enable/disable.
Specify:
[ @1 | @2 | @3 ] immediately after command for channels 1,2 or 3.
Data rate: [ TXRATE | RXRATE ] [ 0 - 52000000 ]
Clocking inversion: [ TCINV | RCINV ] [ ON | OFF ]
Enable / Disable channel: [ TXPORT | RXPORT ] [ ENABLE | DISABLE ]
Example commands:
hssi @1 rxrate Display HSSI channel 1 Rx data rate
hssi @3 tcinv Display HSSI channel 3 Tx clocking inversion
hssi @2 rxport Display HSSI channel 2 Rx Enable/disable
hssi @1 txrate 5000000Set HSSI channel 1 Tx data rate to 5000000 bps
hssi @2 rcinv on Switch HSSI channel 2 Rx clocking inversion on
hssi @3 txport disable Disable HSSI channel 3
ifloopmode Set / Read interface loopback mode(s).
Loopback points are: [ LINELOCAL | LINEFAR | SYSTEMLOCAL | SYSTEMFAR ]
Modes: [ ON | OFF ]
ifprbs Enable / Disable PRBS sequence generation.
Modes: [ ON | OFF ]
ifprbc Display PRBS Error counters.
[ @1 | @2 | @3 ] immediately after command for channels 1,2 or 3.
ifrperc Reset all PRBS Error counters.
[ CONFIRM ] for reset.
ifswrev Display interface firmware (FPGA) revision.
