Events that generate an alarm are such that make it impossible to send or
receive data, e.g. SIM card missing.
7.4.3.1 Interface Status and Statistics
The following status/statistics information can be displayed from the WUI as
well as from the CLI:
WAN interface The mobile network (UMTS or GSM) signal
quality. (*)
Link status: up/down
The protocol/mode used for the connection.
The mobile network currently used for the
connection (HSDPA, UMTS, GPRS, EDGE).
Name of the mobile network operator.
The current state of the mobile network
registration.
WAN IP address
DNS IP address(es)
Total transmitted/received bytes and packets
Amount of error/dropped/overrun packets
LAN interface LAN IP address and subnet mask
DHCP server IP address range and lease time
Port status (up/down) for each physical LAN
port
Total transmitted/received bytes and packets
WLAN interface
Current associations (MAC address)
Current successful authenticated associations
(MAC address and state)
(*) The visual signal quality bars are not only based on signal strength
(RSCP). It also takes the EC/I0 (energy to noise and interference ratio),
since the bandwidth is depended on both values. The CQI (Channel Quality
Indicator) value is also visible from the CLI during a HSDPA connection.
7.4.4 Security Management
All invalid login attempts are recorded in the System Log.
When attempting to log in remotely via SSH or locally via Telnet, the user is
given three login attempts and then the session is ended.
7.4.5 TEMS Investigation Support
The W2x terminals support TEMS Investigation. TEMS Investigation is the
industry-leading tool for troubleshooting, verification, optimization, and
maintenance of mobile networks.
TEMS Investigation connects to the W2x terminals via a virtual serial port
on a computer to the W2x over the Ethernet interface. The computer that
runs the TEMS investigation tool needs a virtual serial driver as well.
