Each Ethernet connectors features a pair of indicator LEDs, with this meaning:
c.
The green LED of the LAN connector shows the existence of data traffic in the Ethernet
interface;
d.
The yellow LED of the LAN connector shows the Ethernet connection speed. When the LED is
off, the data rate is only 10 Mbps, and when the LED is on the data rate rises to 100 Mbps;
e.
Likewise, the green LED of the WAN connector shows the presence of data traffic in the
Ethernet interface;
f.
The yellow LED of the WAN connector shows the interface data rate of the Ethernet
connection. When the LED is off, the interface data rate is 10 Mbps, and when the LED is on,
the data rate rises to 100 Mbps.

Mobile antennas
The TOPEX equipment may use different types of individual (discreet) or collective antennas.
The standard issues are stick-type magnetic-base antennas, while upon request, special antennas
are available, such as high-gain, directional Yagi type (see details below).
The basic version of TOPEX VoiBRIDGE uses a single antenna for connection to mobile
network and for advanced version maximum three (one antenna for each GSM card that has an
internal 4:1 combiner/splitter).
The antennas have a 2,5 m connection cable and a base with magnet for fastening to a
ferrous support. The base is heavy, so the antenna will stand upright even if you place it on a flat
surface that is not metallic.
Note:
The delivered antenna corresponds to the mobile module type from the equipment. Below is
presented an example of an omni directional magnetic antenna with its respective specifications.
Type: “magnetic base antenna”
Directivity: omni directional
Frequency: Multiple bands ( 890 to 960, 1710
to 1880, 1850 to 1990 MHz and 1920-2170
MHz)
Gain: 2 dbi
Polarization: vertical
Height: 72,5 mm total, 43mm active stick
Cable: RG174, length 2,5m
End connector: SME female
Magnetic base: diameter 2,8 cm
