170 CHAPTER 4: FLEXIBLE INTERFACE CARDS
■ The FE1 operating mode supported by the FIC-8E1-F card allows only one n ×
64 kbps bundle to be formed on each interface, where n = 1 to 31. However, a
FIC-8E1 card allows arbitrary grouping of 31 channels and therefore multiple
bundles.
■ The FIC-8E1-F card does not support PRI mode.
n
Given a FIC-8E1 card, the system automatically creates a serial interface for each
timeslot bundle formed on a controller E1 interface.
Interface Attributes The following table describes the interface attributes of the FIC-8E1/FIC-8E1-F
cards.
Interface LEDs FIC-8E1 and FIC-8E1-F panels are similar. The following figures illustrate the
FIC-8E1 panels.
