Card Identification
There are multiple configurations in which an Analog 410 Series card
may be purchased. Each configuration consists of a combination of single
modules and may also include the VPMADT032 echo cancellation
module. See Table 1 on page 24 for a list of the most common TDM410
configurations. See Table 2 on page 25 for a list of the most common
AEX410 configurations. The lists are not complete, but rather an example
of the configurations available.
It is easiest to identify your card by understanding the naming scheme for
each card. The first digit is the maximum port count of the card. The
second digit is the number of FXS (station) modules present on the card.
The third digit is the number of FXO (office) modules present on the card.
