Backhaul consolidation of T1 remains an important function in network operations. With central office space at a premium, carriers need an M13 device that provides cost efficiency, compact size, and built-in intelligent redundancy. ADTRAN has applied its industry-leading expertise in developing carrier class products to the MX2810 M13 multiplexer. The MX2810 offers bandwidth consolidation at a low price and in the smallest footprint available in the industry.The MX2810 houses two hot-swappable controller cards capable of combining independent T1s, E1s, or T1s and E1s on the same DS3. The two controller cards also provide built-in 1:1 redundancy for the DS1 and DS3 signals, as well as built-in BERT (Bit Error Rate Testing) capabilities. When a T1 failure is detected, the MX2810 will not swap to the secondary board until it determines that the failure is hardware-oriented and not a line failure. This intelligent redundancy feature minimizes unnecessary hits to the line that other M13 units may allow.Like all ADTRAN products, the MX2810 offers comprehensive management options, including full management and GUI support from ADTRAN's Total Access EMS. It features a VT100 terminal interface for local configuration. To support SNMP and Telnet management, the MX2810 has an integrated 10Base-T Ethernet port. It has an RS-232 port for network management, as well as an RS-485 port for daisy chaining multiple units. TL1 alarming and provisioning are also supported.
