The board on the left designed produced by Elik-tronics for broadband fixed wireless
access system. the board consists ATM Layer (S/UNI ALTLASPMC Sierra) and S/UNI VERTEX
chip set from PMC Sierra – the processor is POWERQUICC MPC8260 (Motorola)
The Card provides ATM traffic policing (S/UNI-ATLAS),
ATM cell traffic management (S/UNI-APEX) and ATM cell multiplexing.
The CEM communicates the with the more line cards
(design by Elik-tronics,as well) via the serial LVDS
lines using the PMC protocol .(S/UNI-VORTEX and S/UNI-DUPLEX).
On the network side,the Card interfaces via 2 optical transceivers-2x STM1/OC3c interfaces.
