The ADTRAN MX2820 system with a 23-inch chassis houses up to 18 MUX modules to provide nine redundant M13/STS-1 modules in 2U rack units of space.
The ADTRAN MX2820 MUX modules are capable of combining independent T1s, E1s, or T1s and E1s on the same DS3/STS-1 signal. Each pair of MUX modules provides built-in 1:1redundancy on the DS1 and DS3/STS-1 circuits.
With the advent of packet-switching, IP backhaul, and Ethernet-fed base stations, many mobile carriers are looking to curb or even eliminate legacy spending on TDM and Optical infrastructure.
Digital Access Cross Connect Systems (DCS) provide valuable switching and grooming capabilities to a network, but they are often burdened by capacity limitations.
Provide cell site services, access consolidation, and optimization to reduce costs at cell sites using DS3 or SONET/SDH leased facilities for backhaul.
