Section 1, Product Overview MX2800 M13 Multiplexer User Manual
• NEBS Level 3 compliant
NOTE
Information regarding the built-in modem applies to the part numbers
4202290L1, 4202290L2, 4202290L3, and 4202290L4.
2. CONTROLLER CARD 1:1 REDUNDANCY
The MX2800 supports two hot-swappable controller cards which provide 1:1 redundancy for the T1 and
T3 signals and connections. With two cards installed, the MX2800 can recover from circuit or network
failure. Refer to
Section 7 , Circuit and Network Redundancy for more information.
3. T3 OVERVIEW
A T3 provides the same bandwidth as 28 T1s. Typically, leasing a T3 line costs the same as eight to ten
T1s. Using the MX2800, a single T3 can provide internet connectivity and voice (local and long distance)
to individual sites across up to 28 individual DSX-1s. T3 is also extremely cost effective for backhauling
local and long distance voice.
4. SNMP
The MX2800’s embedded SNMP feature allows the unit to be accessed and controlled by a network
manager through the 10Base-T local area network (LAN) port. The MX2800 supports the MIB-II standard,
RFC 1213, and the ADTRAN Enterprise Specific MIB.
NOTE
MIB files are available from ADTRAN in the support section of the
ADTRAN Web page at
www.adtran.com .
The term SNMP broadly refers to the message protocols used to exchange information between the
network management system (NMS) and the managed devices, as well as to the structure of device
management databases. SNMP has three basic components: the network manager, the agent, and the MIB.
Network Manager
The network manager is a set of control programs that collect, control, and present data pertinent to the
operation of the network devices. These programs reside on a network management station.
