Channel Identiﬁer planning

The Channel ID must be in sequential order on a card (no gaps in the

numbering like 1, 2, 4, 7) and they must increase in number. If this is not

done, the card channels are unusable.

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.
