Marketing Information

M13 deployment, the technology that enables multiple T1 delivery from a single T3, is a fairly elementary yet important art for telecommunications carriers.

The MX2820 MUX is capable of combining independent T1s, E1s, or T1s and E1s on the same DS3. Each pair of MUX cards provides built-in 1:1 redundancy on the DS1 and DS3 signals. Advanced diagnostics include CSU loopbacks, NIU loopbacks, C-bit loopbacks, and built-in BERT (Bit Error Rate Testing) capabilities.
