Hi Daniel, Not sure if this is what you are looking for. Table 1.2 of the Enterprise QoS SRND has the Payload size of various CODECs. The paragraph right after this table has the Layer2 overheads.
Thanks, -Dave Message: 4 Date: Sat, 21 Aug 2010 11:45:42 +1200 From: Daniel Berlinski <[email protected]> To: Brian Valentine <[email protected]> Cc: OSL Group <[email protected]> Subject: Re: [OSL | CCIE_Voice] Service URLs Message-ID: <[email protected]> Content-Type: text/plain; charset="iso-8859-1" Guys, I'm preparing for situations with different requirements for codecs usage over the WAN and priority queue sizing. I'm using page 134 od CUCM SRND for locating the formulas for calculating voice payload size and packets per second values for supporting me with potential questions involving codecs such as g723, g726, g728, etc. I use this page alongside with QOS SRND page 33 for L2 overhaeads. Part of the formula for calculating the codec payload size in bytes is the codec rate. I'm not able to find a document (searchable in the exam) with the different codec rates. What do you guys use? Thanks
