Gaps in numbering can deliberately be left between IP trunk cards to
allow for later expansion; for example, to allow for later expansion of a
ITG-Pentium 24-Port trunk card to a Media Card 32-port trunk card.
Preferred ISL channel numbering
This section gives several examples of ISL Channel ID numbering.
Single card, sequential numbering, no gaps ITG-Pentium 24-port
trunk card
This is an example using an ITG-Pentium 24-port trunk card. The first
channel number can be any value, as long as the maximum is less than or
equal to the maximum value of the ISL channel number, which is 382.
Table 39 "Mapping of unit number to ISL Channel number – one card in
system" (page 185)
maps the unit number to the ISL channel number for a
single ITG-Pentium 24-port trunk card.
