Default G450 DSP Maximum Confusion

I have always used the maximum DSP channels in a G450 Media Gateway is 320 (4 daughterboards X 80 channels). Upon closer inspection, the documentation is littered with references providing a maximum of 240 voip channels. The design tools allows input of 320. What is the correct number? Is there some other distinction between the 240 and 320 (besides the obvious 240 is less than 320)?

Default G450 DSP Maximum Confusion

Hi cwculwell,

The G450 prior to release 5.2.1 supports up to 240 channels. in G450, a single DSP childboard supports either 20 or 80 VoIP channels. The G450 supports up to four VoIP DSP childboards. Two types of childboard are supported, one providing 80 active VoIP channels and the other providing 20 active VoIP channels. The maximum number of active channels supported is 320.


Some additional details:

The G450 is a scalable device with a basic configuration consisting of one power supply unit (PSU) and 256 MB RAM, and a single DSP childboard supporting either 20 or 80 VoIP channels. This configuration can be enhanced by adding a redundant PSU, up to two RAM modules of 1 GB each, and up to three additional DSP childboards, increasing the number of VoIP channels to 320 channels
