Table 12 "Real-time capacity of a single card node with all 24 ports enabled"
(page 108)
and Table 13 "Real-time capacity of an ITG-Pentium 24-port
trunk card in the Leader or DCHIP role" (page 108) show the real-time
capacity of the ITG-Pentium 24-port trunk card in the role of Leader card
and the role of DCHIP card.

1 – A DCHIP card does not perform QoS probing. Use the "0 QoS nodes" row for a DCHIP card.
To achieve successful VoIP, a minimum amount of bandwidth must be
reserved. Bandwidth is not guaranteed unless QoS mechanisms are
implemented.
