This section depicts the maximum number of sessions between two codec types on an SBC 5100 with the following DSP card configurations.
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.
The densities highlighted in yellow may be limited by bandwidth depending upon packet size.
