Statistics<br />

Time To Connect<br />

Channels Used By Crosslink<br />

Available Crosslink on Net Access<br />

Crosslink Available<br />

Data utilization from crosslink<br />

Crosslink call statistics<br />

Measure data connections where there is a connection delay and possibly<br />

retries to attempt to acquire a channel to use for the data connections. In<br />

order for a user to get a channel, a repeater and network access must be<br />

assigned to the user and each must have spare channel capacity to support<br />

the data call from the user.<br />

Each network access node has a number of crosslinks available for<br />

connecting to other network access. This monitor measures the channel<br />

usage of each crosslink on each network access. The number of rows in<br />

the table is the number of network accesses times the number of possible<br />

crosslinks per network access.<br />

The crosslinks are allocated to mutually visible network accesses. A<br />

network access may have the capability of up to N crosslinks to other<br />

network accesses where N is the link parameter "'Net Accesses'<br />

Crosslinks: Number available". However due to visibility constraints, at<br />

any time less then a maximum number of crosslinks may be possible.<br />

This monitor measures the number of crosslinks that are available at any<br />

time. It is a level monitor measuring a number for each network access<br />

and that number changes when visibility to another network access<br />

changes. The number of rows in the table is the number of network<br />

accesses.<br />

This monitor is for each possible crosslink on each network access. It is<br />

a level monitor that measures the time it is assigned to a particular network<br />

access and, thus, is available for transmitting data. The number of rows<br />

in the table is the number of network accesses times the number of<br />

crosslinks per network access.<br />

Measure the data transmissions from a crosslink node on the channels<br />

when the channels are available for a crosslink. Once a channel is<br />

allocated, the data utilization of the channel may vary.<br />

Measure the counts of crosslink node calls attempted, carried, blocked<br />

due to traffic, blocked due to visibility, disconnected, and preempted.<br />

This monitor just saves the total call counts.<br />
