Back to DSP Channel Densities for SBC 5000 and 7000 Series

Back to SBC 5x00 DSP Densities

This section depicts the maximum number of sessions between two codec types on an SBC 5200 with SPS100 card installed. If one or two SPS100DB cards are installed, increase these values by a factor of two or three, as appropriate.

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

The density highlighted in blue may be limited by bandwidth depending upon packet size when SBC is configured with SPS100 and either one or two SPS100DBs.

The densities highlighted in yellow may be limited by bandwidth depending upon packet size when SBC is configured with SPS100 and two SPS100DBs.
