The ION is easily set-up and supervised via a graphical user interface (GUI). Remote
units can be commissioned through the use of built-in test equipment. An auto-
leveling function compensates for the optical link loss making installation easy and
quick. The entire system may be monitored remotely via an Andrew OMC. This
platform uses SNMP protocol and is compliant to X.733 standard.
Should a sophisticated interface not be required, the master unit can be
directly connected to the alarm interface of a base station via its contact relay.
Features:
 Multi-channel, multi-operator support
 Reduced visual impact form factor
 Efficient, high power amplifiers
 Single fiber for MIMO and multiple remotes
 Comprehensive operations and management system for configuration and
alarming
 OMC with SNMP according to X.733 standard
 3GPP TS25.143/TS25.106/ TS36.143/TS36.106 and 3GPP2C.S0051-0
compliant
 Easy installation and commissioning
2.3. VSWR ALARMING OPTION
The VSWR Alarming Option is a remote-controlled data ac
quisition system for
monitoring the VSWR of the 700 MHz LTE antenna interfaces. The differential power
detector compares the power levels corresponding with the forward and reverse
waves at the antenna interfaces. A VSWR alarm is always initiated in case of return
loss lower than 2 dB. Return loss higher than 10 dB corresponds always with normal
operation without defect. The return loss range between 2 and 10 dB is the ambiguity
range, depending on the specific phase conditions at the antenna interfaces.
