Restriction On Number Of Cards; Table 4-2 Pri/23 And T1 Card Limitations - Panasonic DBS 576 Technical Manual

Chapter 4. - Installing Additional Cabinets

Restriction on Number of Cards

Note that only a limited number of PRI/23, T1, and CONF cards can be installed in
the flexible slots (FS). Do not attempt to install more than the prescribed maximums.
PRI/23/T1 Card
The switches on the PRI/23 card (see page 2-31), the T1 card (see page 2-33) and the
settings described in the Programming Manual (Section 400) allow you to select 8,
16 or 24 communication channels.
Because each flexible slot can handle a maximum of 8 channels, two or more
flexible slots are effectively occupied per card if you set 16 or more channels. In this
case, certain slots must be left vacant.
The following table shows which slots cannot be used according to the number of set
channels. Do not attempt to install any cards in the unusable slots.
