To determine both the fit and throughput factors use
the table below.

Note that there is a column for cases where the
software will use the Character Control Table
(CCT)
feature.
The
table
is tied
to
hardware.
Its use exerts some overhead which increases the
timing load placed on the affected GPCB mother
board.
If you don't know in your preliminary
configuring whether CCT will be used, assume it
will to give your worst case protection.
It is
used in supporting certain link protocols, such
as BBC,
and
for other
uses.
Note that especially where broadband
(wideband)
speeds are used
(second part of table below)
the
actual number of GPCBs required can be affected
by both the half-board LIUs involved and/or the
high value of their throughput factors.
Remember
that several
of the
LIUs
interface two
lines each.
Each line exerts its own throughput
factor which must be taken
into
account.
Maximum load
factor
for each GPCB
is 99.
Figures in parentheses indicate number of lines
terminated by the LIU.
