[Asterisk-Users] GS BT102 dual ethernet port -bandwidth impact

[Rich Adamson]

FYI for anyone using the dual ethernet ports on a Grandstream BT102.

I'm using a BT102 connected to an HP2524 10/100 switch, which has an 
asterisk box connected directly to it. No VLANs defined or in use.

Measured bandwidth:
  PC -> HP Switch -> Asterisk : actual throughput measured at 94.1 mbps.

  PC -> BT102 -> HP Switch -> Asterisk : actual measured at 8.86 mbps.

The second test (through the BT102) was conducted with a g711 
conversation in progress. Audio quality was noticeably impacted 
presumably due to the half duplex support in the BT102. The BT102 was 
running sip v1.0.5.18 firmware.

The bandwidth tester (older version of NetIQ's QCheck) sent one megabyte 
  bursts of tcp traffic between the two endpoints using 1514 bytes packets.

The tests were run purely to document throughput of the phone when used 
with an attached PC.
