The analog voice/fax network modules provide standard analog interface to the telephony equipment and Public Switched Telephone Network (PSTN). The high-density analog voice/fax network modules (NM-HDA) serve up to 16 analog ports, or four times the number of ports that the low-density analog voice/fax network modules (NM-2V) support. The ports can be in these combinations:

*

4 Foreign Exchange Station (FXS) ports
*

12 FXS ports
*

4 FXS and 4 Foreign Exchange Office (FXO) ports
*

4 FXS and 8 FXO ports
*

12 FXS and 4 FXO ports

The base card supports 4 FXS ports.

*

The addition of an 8-port FXS expansion module (EM) can increase the capacity to 12 FXS ports.
*

The addition of two 4-port FXO EMs can increase the capacity to 8 FXO ports along with 4 FXS ports.
*

The addition of one each of the FXS and FXO EMs can increase the capacity to 12 FXS ports and 4 FXO ports.
