verification on bandwidth consumtion calculation

[bkoum]

hello

i would like to know if these values (for frame header ) are correct while calculating a per voice bandwidth usage...

for the frame header :

14 bytes for Ethernet L2 headers, including 4 bytes of Frame Check Sequence (FCS) or Cyclic Redundancy Check (CRC) , 8 bytes of preambleand , 12 byte inter-frame gap.

(38bytes total ) .

for ethernet medium.

18 bytes for Ethernet L2 headers, including 4 bytes of Frame Check Sequence (FCS) or Cyclic Redundancy Check (CRC).
