The receive propagation delay compensates for the reverse link delay from the receive antenna
of the nearest RAN to the channel card of the cell. This parameter determines the ‘zero time’
for the sector from which all other reverse link delays are calculated.
The maximum differential transmit delay compensates for the delay differential from the
nearest RAN to the furthest RAN within the sector. This parameter determines the search
window sizes necessary to encompass the differential delay from each RAN in the sector
The sector size parameter compensates for the maximum air delay expected at any RAN in the
sector. This parameter represents the maximum distance from any RAN at which the mobile
will be able to access the system. A standard setting for this parameter is 2 miles.
2.3 iDEN
Update neighbor lists to allow hand-off between Digivance CXD and adjacent towers
PTO = 27 (RAN single channel output power)
2.3.1 Digivance CXD base station interface module setup
The interface between the EBTS and Digivance CXD allows for non-duplexed operation. The
simplex block diagram for the BIM is shown in Figure 5-1.
Note: The first receive path of the IDEN EBTS needs to be connected to one of the Digivance
CXD Hub outputs. If it is not, uplink SQE can be affected
