In the name of a module, the first digit indicates the
number of line/trunk jacks it contains; the last digit

If no letters appear after the number, a line/trunk
module provides loop-start trunks or an extension
jack module provides analog or tip/ring jacks. For
example, a 408 GS/LS MLX module contains four
line/trunk jacks and eight digital (MLX) extension
jacks, provides either loop-start (LS) or ground-start
(GS)trunks . There are also modules for the proces-
sor and power supply.
