Connecting Analog Modem Network Modules to a Network 11-5
Interface Numbering
Figure 11-5 Cisco 2600 Slot Numbers
Ports in the 8-port and 16-port analog modem network modules are numbered in the same
pattern as slot numbers, beginning at 0 at the lower right and continuing from right to left
and (in the 16-port module) from bottom to top.
The interface number of a port is determined in the following way:
interface-number = (32 x slot-number) + port-number + 1
For example, modem port 12 in slot 1 corresponds to interface number (32 x 1) + 12+1=
45. This is also the line number for the port. Port 12 in slot 1 is always assigned interface
number 45, regardless of whether the module in slot 0 is an 8-port analog modem network
module, a 16-port analog modem module, or some other kind of module entirely, or even
whether there is a network module in slot 0 at all. If you move the module from slot 1 to a
different slot, however, its interface numbers change.
Table 11-1 shows the range of interface numbers available for each type of analog modem
network module in each router slot. (Interface 0 is automatically assigned to the console.)
