coded and held in card positions 18 through 20. These card positions
are fixed for all systems.
3.06 The number of line, trunk and receiver cards must be specified
to fulfil the individual requirements of each customer. Each line
card contains eight independent line circuits. Each trunk card contains
two or four trunk circuits depending on the trunk type. The receiver
card may contain two receiver circuits (dual type) or four receiver
circuits (quad type). See Figure 3-2 which shows the maximum con-
figurations of cards.
Equipment Shelf 2
3.07 To expand the SX-200 system to its maximum capability, a
second equipment shelf must be employed. Equipment shelf 2
is identical in construction to shelf 1 and provides an additional 12
card positions, which may be used to house line or trunk cards. Card
positions 13 through 22 on shelf 2 are not used.
Electrical Characteristics
3.08 The PBX systems are designed to operate from a 48 Vdc supply
which is derived from either the commercial AC supply or a
reserve battery supply. Table 3-1 details the electrical characteristics
of the system.
