Interface Numbering
Numbering Rule of Service Interfaces on the NE20E-S4
A subcard slot number is the number of the slot where an interface's subcard resides. A
subcard slot number ranges from 1 to 4.
An interface number on the subcard starts with 0, and its maximum value is determined
by the actual number of interfaces on the subcard.
The following figure shows how a service interface is numbered on the NE20E-S4.
