By manipulating Latency, Response time and Priority, simultaneous transmit and receive tasks can be performed on all the 4 ports (124 TS).

Here are some typical settings:

  • 1.6 GHz PC, WIN 2K OS Latency-550, Response-150, Priority-3 - for simultaneous transmit and receive on all the 4 ports (124 TS) of an E1
  • 800 MHZ PC, WIN 2K and WIN NT OS
    • Receive Only or Transmit Only up to 124 different files (4 E1 ports) with
      Latency-1000,Response-500 and Priority-1 parameters [WIN 2K]
    • Receive and Transmit simultaneously up to 72 different files with
      Latency-1000,Response-600 and Priority-1 parameters [WIN 2K]
    • Receive and Transmit simultaneously up to 62 different files with
      Latency-800, Response-500 and Priority-1 parameters [WIN NT]
    • Transmit only up to 124 different files with
      Latency-1000, Response-600 and Priority-1 parameters [WIN NT]
    Eg:
    tx server file "qrss.ber" #1:1 continuous; ...
    tx server file "qrss.ber" #2:1 continuous;
  • Transmit only or Transmit and receive simultaneously on all the timeslots at a time on each of 4 ports with one combined command for all timeslots. Latency-80, Response time-500 and Priority-3. [PC- 800 MHz onwards On T1/E1 cards].
    Eg:
    rx server file "rec1.ala" #1:1..31 1000;
    tx server file "qrss.ber" #2:1..31;
    rx server file "rec2.ala" #1:1..31 1000;
    tx server file "qrss1.ber" #2:1..31;
  • Receive only on all the timeslots at a time on each of 4 ports with one combined command for all timeslots. Latency-20, Response time-500 and Priority-3. [PC- 1.6GHz On T1/E1 cards].
    Eg:
    rx server file "rec1.ala" #1:1..31 1000;
    rx server file "rec2.ala" #2:1..31;

Important Note:

"TxRx underflow" problem gets improved when the priority in the task manager for the GL Server is set to "Real time". (Under Task Manager, select "Processes" tab, go to view - "select columns - check "Base priority" - Select "GL Server" for image name and "Set Priority" to "Real Time".)
