Transmission and Access

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-case multiplexer that can significantly increase T1 output while minimizing space that 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 nine redundant M13 multiplexers in a 23-inch chassis and two rack units of space. Up to seven redundant M13 multiplexers can be based in a 19-inch chassis. In addition, the M2820 can provide up to 81 M13s in a 7-foot bay using active cooling (fans and heat baffles) or up to 63 M13s in a 7-foot bay using passive cooling (heat baffles).
The MX2820 MUX cards are 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.

The OPTI-6100 OMM3VIR IEEE 1613 has been tested to IEEE 1613 standards and is suitable for applications in electric power substations. The basic functionality and performance remains the same as the basic NEBS-compliant OPTI-6100 utilized in carrier applications. Customers should be aware that 1613 compliance is, in most cases, mutually exclusive with Telcordia NEBS Level 3 testing, therefore, modules are either NEBS- or 1613-compliant, but not both, on the same modules. Care should be taken to order the correct module.

The MX2800 is a M13 multiplexer that consolidates T1 and E1 signals into a T3 circuit. This unit provides a cost-effective, versatile tool for combining independent T1s, E1s or a combination of the two over the same T3 circuit. It also houses two hot-swappable controller cards which provide 1:1 redundancy for the T1 and T3 signals, as well as the T3 connections. Embedded simple network management protocol (SNMP) and Telnet are available through the modem port using serial line Internet protocol/point-to-point (SLIP/PPP) or through the 10BASE-T Ethernet port. Using the Management Information Base II (MIB II), RFC 1407 standards and an ADTRAN enterprise MIIB, the MX2800 can be configured, monitored and diagnosed with standard SNMP network management programs such as Hewlett Packard’s HP OpenView and Cabletron’s Spectrum. In addition, the SysLog Host Daemon allows remote monitoring, collecting and logging of MX2800 events in real time. This information is useful during installation setups and/or troubleshooting. Complete configuration, loopbacks and performance monitoring are available through SNMP, Telnet or a VT100 terminal interface. This connection can be made via Ethernet, a local EIA-232 link or through the built-in V.34 modem. The modem can dial out a "cry for help" for units located in unmanned facilities. The MX2800 is designed for installation in a 19- or 23-inch rack.
