Half Duplex data transmission means that data can be transmitted in both directions on a
signal carrier, but not at the same time. For example, on a local area network using a
technology that has half duplex transmission, one workstation can send data on the line and
then immediately receive data on the line from the same direction in which data was just
transmitted.
MAC Address
MAC address of the unit.
Remote MAC Address
MAC address of the remote unit.
Remote IP Address
Hyperlink to the other side of the Link. The IP address of the peer link is displayed if the Link
is UP, otherwise "unavailable" is displayed.
Telecoms Status
Indicates the current status of the telecoms channel. Channels which are disabled during
installation are marked as such. Correctly operating channels display "Up" on a green
background, but alarm conditions (described in Section 7.2.1 "Home Page Alarm Display")
have a red background.
Telecoms Latency
If E1 or T1 is enabled, this shows the end-to-end latency of the telecoms link.
Automatic Page Refresh Period in Seconds
Only displayed when the user is logged on as system administrator. Enter the required refresh
period.
Wireless Link Status
As the attribute name suggests it displays the current status of the wireless link. A state of
'Up' on a green background indicates that a point-to-point link is established. A state of 'Down'
on a red background indicates that the wireless link is not established.
Maximum Transmit Power
The maximum transmit power that the local wireless unit is permitted to use to sustain a link.
Remote Maximum Transmit Power
The maximum transmit power that the remote wireless unit is permitted to use to sustain a
link.
Transmit Power
Transmit power histogram is expressed in dBm and presented as: max, mean, min, and
latest. The max, min and latest are true instantaneous measurements; the mean is the mean
of a set of one second means. The Transmit Power may be less than the maximum permitted
Transmit Power due to the TPC (Transmit Power Control) mechanism. This mechanism
adjusts Transmit Power to achieve best link performance while minimizing the interference it
causes to other users of this part of the Spectrum. See Section 7.3.1 "Histogram Data".
Receive Power
Receive power histogram is expressed in dBm and presented as: max, mean, min, and latest.
The max, min and latest are true instantaneous measurements; the mean is the mean of a set
of one second means. See Section 7.3.1 "Histogram Data".
