STEP PROCEDURE

2. Select the card to be configured, click the right mouse button and from the drop menu
select AS4000 DA DTU Properties.

Max Net Entry Channels: On start-up the STs are made aware of the network and data
is downloaded into each ST. The larger the number of NET entry channels the shorter the
time to get the system operational. One channel per shelf within the system is always
configured to run net entry, but in addition, the user can configure additional potential net
entry channels. (Selected on the DTU properties in Sitespan). Each channel selected
here requires a full RW i.e. 160K of bandwidth, and therefore, if the RW is used for net
entry, it is removed in entirety from the available pool for traffic.
Free List: The free list allocates the free list at each traffic rate. (160k, 80k, 40k) The
way the list is divided depends on the ST population. If a channel is not available at a
required rate the next highest rate is selected.
Incoming Call Availability: Incoming call availability is calculated from the allocation
and distribution of channels across the free lists
FRU State: In Service makes the FRU available for system use.
