• Full configuration for the SDM product is defined as operating with five fully utilized subrate channels per
DS0 with all five RS-232C drivers active per subrate channel. This totals 25 RS-232C drivers active on
an SDM line card. If an application is such that half as many (or less) RS-232C drivers are needed, then
twice the number of SDM line cards can be powered, as shown in the parentheses as an "Optional"
amount.
