Note that the calculated Bandwidth value for this table entry, 97.523 kHz, is for
the carrier only. The bandwidth Slot that will be assigned for this carrier will
include the additional guardband that is defined for the associated Pool. In this
example, a guardband of 30% is used.
An InBand switching session for the Remote site (R_2) can be generated using
the Application Sessions feature, with a specified data rate of 192 kbps at QPSK
3/4 (figure 6-45).
Figure 6-45 Manual Application Switch Session, R_2
Following the VMS switch, the site status for R_2 changes, indicating a new bit
rate of 256 kbps at 8PSK 7/8 (figure 6-46).
Figure 6-46 Updated Status View, R_2
The carrier appearance in the Spectrum view displays with an allocated band-
width of 97.523 kHz (figure 6-47). When the guardband is added to this value,
the assigned bandwidth slot becomes 126.781 kHz, just as was calculated in the
example equation previously.
