Product Overview
INTRODUCTION
The MX2800 is an 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 combi-
nation of the two over the same T3 circuit.
The MX2800 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 protocol (SLIP/PPP) or through
the 10Base-T Ethernet port. Using the Management Information Base II (MIB II), RFC 1407
standards, and an ADTRAN enterprise MIB, 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-inch or
23-inch rack.
The major features of the MX2800 are as follows:
• Built-in 1:1 redundancy
• Hot-swappable controller cards
• Independent, dual-load sharing, redundant power supplies
• Embedded SNMP and Telnet management through 10Base-T Ethernet or SLIP/PPP dialup
• Detailed performance monitoring for local and remote units
• Simplified configuration through the VT100 terminal menu structure
• Integrated V.34 modem for dial-up and dial-down access
• Capability of backhauling multiple service types (T1/E1)
•AC or DC power
• Available –48V or 24V power supplies
• External DS3 clock option
