4. In order to acquire a test radio link using an ST, Sitespan must be used to place RW
codes ‘Out of Service’ (OOS) for either 10k or 160k bandwidths. These can be selected
from the DTU card properties. The options for each RW code are:
• IS - The RW is in service
• OOS - This takes the RW out of service.
• OOS(10k) - This puts the RW in Test Mode, allocating a 10kbit/s
bandwidth.
• OOS(160k) - This puts the RW in Test Mode, allocating a 160kbit/s
bandwidth.
The DTU card view shows all of the RW codes, and their current state within the
system (i.e. OOS or IS).
IMPORTANT NOTE: An RW code can only be placed Out of Service if it is currently
not in use by the system. Before proceeding, it is important that the DTU card view is
checked, to ensure that the RW code is in the desired state.
5. In the RW management window place the mouse pointer over the IS for RW 1 click
left mouse button until OOS is selected. Repeat for RW2 and RW3 to prepare for
commissioning. Once RW codes have been reserved for Test links, the ST can be
programmed in the usual method, although the RW channels that the 10kbit/s and
160kbit/s links are acquired on, must be the same as the ones set-up in the DTU card
properties (i.e. NOT RW 15!).
