Interface Numbering
Individual digital modem ports are not physically distinct, but Cisco IOS software
identifies each modem uniquely through its slot number and a port number.
In Cisco 3600 series routers, slot numbers begin at 0 at the bottom right of the chassis, as
viewed from the rear. In Cisco 3640 routers, the bottom row of slots is numbered 0 and 1
and the top row is numbered 2 and 3, as shown in Figure 10-2.
Figure 10-2 Cisco 3640 Slot Numbers
Each digital modem module can hold up to five banks of MICA modules, numbered 0 to 4
from left to right (as viewed from the rear of the router). Each MICA module holds six
modems, which are assigned modem numbers 0 to 5.
Each modem in a digital modem module is also assigned a port number in the range 0 to
29. Modems in the left MICA module (as viewed from the rear of the router), bank 0, are
assigned port numbers 0 to 5. Additional MICA modules, if present, are assigned the port
numbers shown in Table 10-1.
