appropriate identification of these ports. The port identification is the
same for all cards in this series.
It is important to identify the type and location of your 800 Series
modules. You will need this information during the Asterisk
configuration.
The ports available for use on the 800 Series cards are not continuous.
The ports available for use depend upon the type of module used, and the
placement of the module on the card. The cards can accept 2 quad
modules, for a total of 8 ports. If single modules are used, only 2 single
modules can occupy the same space as a quad module. The single module
ports are identified on the card and their corresponding RJ11 ports are
identified below. Please refer to Figure 2 for an example using single
modules, and Figure 3 for an example using quad modules.
If a single module is used, the RJ11 port available for use will be the port
corresponding to the location of the module on the card. The following
ports correspond to the single module ports as shown in Figure 2.
 RJ11 Port 1 is used by Single Module Port 1
 RJ11 Port 2 is used by Single Module Port 2
 RJ11 Port 5 is used by Single Module Port 5
 RJ11 Port 6 is used by Single Module Port 6
