Chapter 1 Introduction AirMux-200 Installation and Operation Manual
1-2 Overview
AirMux-200 can be configured to operate over several frequency
channels with a carrier step resolution of 10 MHz. The number of the
frequency channels depends on the selected operating band.
AirMux-200 uses Direct Sequence Spread Spectrum technology
combined with powerful forward error correction to ensure high
reliability and security over license exempt 5.725–5.850 GHz
frequencies. AirMux-200 operation complies with the FCC
15.401&15.407 requirements.
AirMux-200 employs Time Division Duplex (TDD) transmission. This
technology simplifies the installation and configuration procedure.
There is no need to plan and to allocate separate channels for the
uplink and downlink data streams.
Operation over 5.725–5.850 GHz bands is not affected by harsh
weather conditions, such as fog, heavy rain etc.
LAN Interface
The AirMux-200 LAN port provides two 10/100BaseT interfaces with
autonegotiation and transparent VLAN support. Traffic handling is
provided by a MAC-level self-learning bridge.
TDM Interface
The AirMux-200 TDM interface accepts E1 or T1 traffic, supporting the
following:
• Framed and unframed operation (E1 and T1)
• ESF and SF framing (T1)
• AMI and B8ZS zero suppression (T1)
• CRC-4 bits generation (E1)
• Flexible timeslot allocation (framed E1 and T1).
Management
AirMux-200 has full local and remote management capabilities. The
user-friendly SNMP-based management tool provides full end-to-end
configuration and performance monitoring capabilities.
Diagnostics and Performance Monitoring
AirMux-200 supports activating local and remote loopbacks on E1 or
T1 links.
