 can accommodate up to two SPS100DB daughter board modules for increased DSP densities. However, the maximum number of sessions on an

 is 10,000 even though a three-DSP configuration supports over 10,000 sessions for some codecs.

Info

If one or both SPS100DB modules are installed, multiply the values in the table below by a factor of two or three, as appropriate, to obtain DSP density values. DSP density values are approximate and intended for use as a general guide when estimating transcoding capabilities.

Values associated with the same codec (i.e. like-codec to like-codec) refer to re-packetization.

Note

Cells highlighted in the matrix below may be limited by bandwidth depending on packet size for the following SPS configurations/color combinations:

  • SPS100: yellow
  • SPS100 + one or two SPS100DB: yellow, green
