Fractional
can be used when fewer than 24 trunks are needed.
Fractional allows you to use only a portion of the 24 channels provided
on the card.
Though each Interface provides 24 trunk channels, trunks do not
increase the overall trunk capacity of the DBS. Each channel subtracts
from the total number of analog trunks that can be installed.
With CPC-B earlier than 5.00, the number of analog trunks that can be
used with Fractional
are always decremented in quantities of 8.
For example, if you are installing a in a DBS 96 and you only want to
use 12 channels, the logical number of analog trunks that would be
available is 20 (32 12 = 20).
The number of analog trunks must be decremented in quantities of 8. the
actual number of analog trunks that can be used is 16:
(32 total trunks 16 (two increments) = 16.)
Tables.69 through 11 show the possible combinations of analog and
digital trunks assignments based on system size.
The trunk numbering shown in these tables is determined by backplane
trunk port assignments. Therefore, the numbering cannot be changed.
With CPC-B 5.00 and higher and the VB-435 Loop Start Trunk Card,
the number of analog trunks that can be used with Fractional are
decremented in quantities of 1.
Note: Analog trunks are numbered beginning with 1.” T 1 trunk nel
are numbered beginning with the highest trunk channel used.
