Introduction
The 4-port/8-port E1 ATM inverse multiplexing interface module (FIC-IMA-4E1/FIC-IMA-8E1)
provides four/eight E1 interfaces that support the IMA (inverse multiplexing for ATM) technology.
The IMA technology combines multiple low-speed links into a group to support a high-speed ATM
cell stream: It distributes an ATM cell stream over multiple low-speed E1 links on cell by cell basis at
the transmission end and reassembles the cells on the low-speed E1 links into the original stream at
the far end. This technology provides a scalable and cost-effective solution, and is commonly used in
PDH networks to transport ATM cells.
