Each 6-port module may include 6 modems. Therefore, in a fully populated MICA card, you can have up to 60 modems. Or, in a fully populated access server chassis, you can have up to 120 modems. Ten of these modem modules can be configured on each of two cards for a total of 60 ports per card or a total of 120 ports per chassis. The 6-port modules cannot be used as standalone cards.
