Definition 16, 24, 32, and 40 kbps Term What is the bit rate in kb/s for the G.727 codec? Definition Varies, with 2, 3, 4, and 5 kbps Term What is the bit rate in kb/s for the G.728 codec? Definition 16 kbps Term What is the bit rate in kb/s for the G.729 codec? Definition 8 kbps Term What is the bit rate in kb/s for the G.723.1 codec? Definition 5.6 or 6.3 kbps Term What are the bite rates for the following codec : 1. G711 2. G.722 3. G.723 4. G.726 5. G728  Definition 1. 64 kbps 2. 64 kbps 3. 24 and 40 kbps 4. 16/24/32/40 kbps 5.  16 kbps Term What are the bit rates for the following codec? 1. G.721 2. G.722.1 3. G.723.1 4. G.727 5. G.729  Definition 1. 32 kbps 2. 24/32 kbps 3. 5.6/6.3 kbps 4. varies, from 2/3/4/5 kbps 5 8 kbps Term What is the basic formula when calculating how many calls can be made when given the codec be used, the payload size, the packet header size, and wheather or not CRTP is being used? Definition 1. Find out the bit rate of the specified codec. 2. Calculate the total size of the payload. This would be the starting payload + the header size + 40 bytes (IP+UDP+RTP) (2-4 bytes is CRTP is used) 3. Divide the new payload by the starting payload, to get the new percent needed 4. Multiply the new percent with the bit rate for the specified codec 5. Divide the available bandwidth by the new requirement per call  Term Definition
