Alcatel-Lucent E5PQAHMAAA Transmission Interface Card is a 5ESS switching-system module that provides the transmission interface for line and trunk connections within the Alcatel-Lucent 5ESS network. In AT&T equipment listings, it appears as KBN6 S12:13 and is identified by the E5PQAHMAAA part number, tying it to AT&T's 5ESS deployment configurations. Designed as a replacement or spare for legacy 5ESS installations, the E5PQAHMAAA must be matched to the correct 5ESS chassis, slot, and software revision for proper operation.
