E1 CE 75 OHM 8 PORT CARD The 8 Port E1 Circuit Emulation Card with 75 ohm interface impedance multiplexes and demultiplexes the circuits carried over a TDM channelized link and performs the necessary operations to allow the transport of these circuits through an ATM network. This card supports both structured and unstructured service as defined by the ATM Forum. This card is not certified for use with the CE-EC echo cancellation modules. Use the 120 ohm 8-port CE card with the CE-EC modules.
