Note: The line card aassignments are designated by row (A, B, or C),
slot number (1 to 10), and Circuit (A or B). For example, B3A
identifies the line card in row B, slot 3, using circuit A.
Each slot in the Analog Link SRU drawer accommodates
two 2-wire circuits, or one 4-wire circuit (both circuits
A & B are used).
When the line card contains one 2-wire circuit,
the A pair is used and the B pair has no connection.
