The logical slot numbers are as follows: • 0 for all built-in Cisco 2-port T1/E1-RAN interface card slots • 1 for the lower network module slot • 2 for the upper network module slot The numbering format is: / / For example: Serial 0/0/0 (HWIC slot 0) Serial 1/0/0 (NM slot 1) Cisco 3825 Mobile Wireless Edge Router Software Configuration Guide 3-2 OL-15667-03
