MX2800 redundant AC with patch panel 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.
