OC3/STM1 Configuration
SEE APPENDIX C. OPTIONAL PIIC (PLUG-IN INTERFACE CARD) MODULES:
• Sect. C.2.2 OC-3 Single/Multi Mode PIIC Module Kits (CEFD P/N
KT-000256/257)
• Sect. C.2.3 STM-1 Copper PIIC Module Kit (CEFD P/N KT-0000255)
This section displays whenever the OC-3 Single Mode, OC-3 Multi Mode, or STM-1 Copper PIIC is
installed in the applicable PIIC slot:
• Use the Interface Type drop-down list to select None or OC3/STM1.
• Use the Tx Clock Source drop-down list to select Tx Clock or Rx Sat.
Comtech EF Data strongly recommends that you select Tx Clock unless a high
stability External Clock is present and timing of the network requires all devices
to be locked to the External Clock.
• Use the Rx Clock Source drop-down list to select Tx Clock, Int Clk, or Rx Sat.
Comtech EF Data strongly recommends that you select Rx Sat unless a high
stability External Clock is present and timing of the network requires all devices
to be locked to the External Clock.
• Enter an Rx Buffer Size (ms) from 2 ms to 75 ms, in 0.5 ms steps.
Click [Reset Buffer] to clear the Rx Buffer.
Click [Configure PIIC] to save your OC-3 or STM-1 configuration settings.
ASI Configuration
SEE APPENDIX C. OPTIONAL PIIC (PLUG-IN INTERFACE CARD) MODULES:
Sect. C.2.4 DVB ASI (Asynchronous Serial Interface) PIIC Module (CEFD P/N
PL-0022015)
This section displays whenever the DVB ASI PIIC is installed in the applicable PIIC slot.
• Use the Tx Mode drop-down list to select Off, ASI-Norm, or ASI-Adv.
• Use the Tx Frame drop-down list to select None, TS-188, or TS-204.
• Use the Tx ReStamp drop-down list to select Off or On.
• Enter the desired Tx DataRate (kbps) from 1000 kbps to 216,000 kbps.
• Use the Rx Mode drop-down list to select Off or ASI-Norm.
• Use the Rx Frame drop-down list to select None, TS-188, or TS-204.
• Use the Rx Output drop-down list to select Stream or Burst.
• Enter the desired Rx DataRate (kbps) from 1000 kbps to 216,000 kbps.
• Enter an Rx Buffer Size (ms) from 2 ms to 75 ms, in 0.5 ms steps.
Click [Configure PIIC] to clear the Rx Buffer.
Click [Configure PIIC] to save your ASI configuration settings.
