DATA Port Ethernet Settings

DATA Speed This is the speed of the Data port.

Thedefault is Auto. The airFiberX radio automatically

negotiates transmission parameters, such as speed and

duplex, with its counterpart. In this process, the networked

devices first share their capabilities and then choose the

fastest transmission mode they both support.

To manually specify the maximum transmission link

speed and duplex mode, select one of the following

options: 100 Mbps‑Full, 100Mbps‑Half, 10Mbps‑Full, or

10Mbps‑Half.

To disable the Ethernet data port, select Disabled.

Note: If Disabled is selected, ensure that the radio

is accessible using the Management Ethernet port

or over the RF link (with in-band management

enabled), or all communication with the radio will

be lost.

Full-duplex mode allows communication in both

directions simultaneously. Half-duplex mode allows

communication in one direction at a time, alternating

between transmission and reception.

Flow Control If enabled, the airFiberX radio generates

and responds to Ethernet layer PAUSE frames. The

airFiberX radio regulates inbound traffic from the

customer’s network to avoid buffer overflows within the

airFiberX radio. Flow control has the effect of controlling

the inter-packet spacing of packets headed into the

airFiber Data interface.

Multicast Filter If enabled, the filter blocks multicast

traffic from overloading the CPU when in-band

management is enabled. This allows the airFiberX radio

to be managed in-band when the customer’s network is

carrying large volumes of multicast traffic, such as IPTV.

The filter does not block multicast traffic going over

the radio; it simply blocks it from reaching the airFiber’s

management interface CPU.

Track Radio Link If this option is enabled, the airFiberX

radio disconnects the Data port’s Ethernet link when the

RF link is lost (The Management port is never disabled by

this option). The Track Radio Link option is useful because

it quickly indicates a “link lost” condition to the customer’s

routing equipment (such as a direct connection to

OSPF-enabled routers).

• Disabled The Track Radio Link option is disabled by

default. The Data port’s Ethernet link will always remain

up regardless of the RF link state.

• Use Timeout Duration This option is designed for use

by operators who are using in-band management. Two

timers control the Data port’s Ethernet link.

RF Link Ethernet Link Notes

Goes down for

the first time

The Ethernet link goes

down and remains

down for the number

of seconds specified by

the Link Off Duration

timer.

The Ethernet link will

then come back up

so that the airFiberX

radio can be managed

even when the RF link

is down.

Even if the RF link goes

back up before the

Link Off Duration timer

elapses, the Ethernet

link remains down.

The Ethernet link’s

downtime is long

enough to signal to

the customer’s routing

equipment that the

path is lost.

Goes down

for the

secondtime

The Ethernet link

remains up as long as

time remains on the

Link Off Spacing timer.

When the Link Off

Spacing timer elapses,

then the Ethernet link

goes down again for

the number of seconds

specified by the Link

Off Duration timer. (This

happens only if the RF

link is still down.)

The Ethernet link’s

uptime is long enough

so the operator has

enough time to access

the airFiberX radio,

make configuration

changes, and save those

changes.

Sufficient Ethernet link

uptime is vital when a

RF link is constantly up

and down.

If the Use Timeout Duration option is enabled, the Track

Radio Link option and the following timers are enabled:

- Link Off Duration The Link Off Duration timer

controls the length of time the Data port’s Ethernet

link will be down if the RF link goes down. Enter the

number of seconds that the Ethernet link should be

offline. For example, if this is set to 10seconds, then

when the RF link goes down, the Ethernet link will go

down and remain down for 10seconds (regardless of

the RF link state), and then it will go back up.

- Link Off Spacing

The Link Off Spacing timer controls

the length of time the airFiberX radio will wait before

allowing the Data port’s Ethernet link to go down for a

second time if the RF link goes down again. Enter the

minimum interval (in seconds) between offline events

of the Ethernet link, regardless of the RF link status.

The value for Link Off Spacing should be larger than the

value for Link Off Duration, and it should be enough

time for the operator to access the airFiberX radio,

make any configuration changes, and apply those

changes.

Note: If the Link Off Spacing timer is set to

0seconds, then the Ethernet link will only use the

Link Off Duration timer. If the Link Off Duration

timer is set to 10 seconds and the RF link goes

down, then the Ethernet link will go down for

10seconds and then go back up regardless of the

RF link state. If the RF link is still down, then the

Ethernet link will not go down again until the RF

link goes back up and then down again.

Introduction Listen Before Talk (LBT) is a requirement for the 3.6 GHz band in North America and Canada. Because exclusive licenses for the 3650-3700 MHz band are not granted within the United States, operators must take steps to minimize potential interference in this band.

airFiber® X User Guide Appendix B: Listen Before Talk Opportunities for Other Transmitters to Operate No differences are performed between start-up mode and operational mode. The Master/Slave device goes into an energy scanning mode where it is allowed to do one full cycle of energy detection before it is allowed to transmit. The scan is a mode where the average energy is accumulated to compare against the programmed detection threshold.
