Throughput may decrease by up to 10% as a function of range, due to propagation
delay.
LAN Interface
The AirMux-200 LAN port provides 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:
•
Unframed operation (E1 and T1)
•
AMI and B8ZS zero suppression (T1).
Management
AirMux-200 has full local and remote management capabilities. The user-friendly
SNMP-based management tool provides full end-to-end configuration, event log
and performance monitoring capabilities.
Diagnostics and Performance Monitoring
AirMux-200 supports activating local and remote loopbacks on E1/T1 links.
AirMux-200 constantly monitors the data transmission process, evaluates received
signal strength, and signal quality. It also monitors received traffic and frame rate
(FPS) for local and remote units.
Optional External Antenna
An optional flat panel 28 dBi external antenna increases the operation range of
AirMux-200 up to 80 km (50 miles).
