M13 deployment, the technology that enables multiple T1 delivery from a single T3, is a fairly elementary yet important art for telecommunications carriers. Demand for T1s is affected by existing Remote Terminals (RTs) that are space constrained. Supplying a carrier-class multiplexer that can significantly increase T1 output while minimizing space has been the challenge for telecommunications equipment providers. Carriers facing costs for IP addressing save money because M13 capability can be added yet each MX2820 uses only a single IP address. In areas where multiple M13s are needed, the ADTRAN MX2820 High-Density M13 Multiplexer frees up valuable rack space with a high-density chassis. The MX2820 houses up to 18 multiplexer cards to provide 9 redundant M13 multiplexers in a 23-inch chassis and 2 rack units of space. Up to 7 redundant M13 multiplexers can be based in a 19-inch chassis. In addition, the MX2820 can provide up to 72 M13s in a 7-foot bay.
A great idea gets even better
Using an M13 multiplexer to manage your DS1 business has its advantages - lower costs, simplified operations and new business opportunities. The ADTRAN MX2820 helps you address space, cost, heat and management concerns with a high-efficiency, space-saving M13 platform.
The MX2820 requires just 2U of rack space to provide nine fully redundant M13s in a 23-inch chassis. Using the MX2820, a NEBS-compliant 7-foot rack will accommodate 63 redundant M13 multiplexers with passive cooling or 81 redundant M13 multiplexers with active cooling.
1:1 protection at 1: N cost
To eliminate problems with switching relays, single points-of-failure, and design complexities associated with 1: N systems. ADTRAN's MX2820 offers a unique 1:1 protection system. This system offers redundancy on every DS3 and DS1 interface. This is the result of ADTRAN's custom silicon development that reduces failover switch time and increases system reliability.
Effective Cable Management
ADTRAN understands the challenges of high-density wiring configurations from bend radius to signal crosstalk and has partnerships with connector manufacturers to pioneer a new standard in dense-cable management. ADTRAN supplies a variety of cost-effective adapter cables and custom length configurations, to produce the optimum implementation to fit customer cabling needs.
