Which codec complexity mode, when deployed on Cisco IOS routers with DSPs using the C5510 chipset, supports the most G.711 calls per DSP?
The flex parameter allows the complexity to automatically adjust to either medium or high complexity depending on the needs of a call.
For example, if a call uses the G.711 codec, the C5510 chipset automatically adjusts to the medium-complexity mode.
However, if the call uses G.729, the C5510 chipset uses the high complexity mode.
The codec complexity mode affects the number of calls that can be supported per DSP (Digital Signal Processor). The C5510 chipset is commonly used in Cisco IOS routers and supports multiple codec complexity modes.
The G.711 codec is a common codec used for voice calls and has a complexity level of 1. The complexity mode is a measure of the processing power required to encode or decode a codec.
The answer to this question would be "A. Low" codec complexity mode, which is the most efficient mode and supports up to 32 G.711 calls per DSP. The other complexity modes (medium, high, secure, and flex) require more processing power and support fewer G.711 calls per DSP.
Therefore, the Low complexity mode provides the highest number of G.711 calls per DSP and is the most efficient mode for G.711 calls on Cisco IOS routers with C5510 chipset DSPs.
