…replacement for Lucent SLC-5 legacy CTU with preservation of legacy CTU functionality * Full-featured ATM multiplexer in a compact footprint * Four T1/IMA ports capable of operation with fiber multiplexer or direct copper connections * Advanced ATM service support, sophisticated traffic management capabilities…

…provides T1, IMA and DS3 network interface options to utilize existing backhaul facilities. The T1 interface can be connected to a fiber mux or directly interface to copper backhaul facilities. IMA allows the ATM data stream to be split across T1 circuits, thereby combining the bandwidth of multiple T1 links…

CNX-5 Configurations The CNX-5 system is available in T1 IMA and DS3 configurations that provide the flexibility to utilize existing backhaul facilities and meet growing DSL demand. Both configurations use Enhanced Channels Units (ECUs) and are managed by the CatenaView EMS. The table below summarizes…
