Features To connect the OpenCom 100 to existing company hardware, "actor" ports (output) and "sensor" ports (input) can be provided by retrofitting a doorstation interface card. For example, this can be used to operate a door opener and a doorbell via the system (this requires additional equipment). There are two variants of doorstation equipment interface cards: ■ On an OpenCom 130 or an OpenCom 131 a "M100-TFE" interface card can be operated. This card provides two actor ports and three sensor ports to connect doorstation equipment. ■ On an OpenCom 150 a "M100-TFE-2" interface card can be operated. This card provides four actor ports and four sensor ports. This card enables to operate two entrance intercom systems, each providing two sensor ports for bell keys. OpenCom 100 enables you to use CTI (Computer Telephony Integration) applications. The TAPI (Telephony Application Programming Interface) and CSTA (Services for Computer Supported Telecommunications Applications) standards are supported for the purpose of integrating CTI applications. OpenCom 100 also features an integrated browser-based CTI application, the OpenCTI 50. The OpenCTI 50 allow users to call up and use telephone functions from their PCs. Note: As an alternative to the COM port, call charges can also be transmitted to an external programme for recording charges via the CSTA (Computer Supported Telecommunications Application). There is a corresponding conversion programme available for doing so. This is on the product CD in the "\Aastra" directory. If you desire further information, please contact your representative or Aastra sales. Cascading Using the expansion module, the OpenCom 130 can be cascaded with a second OpenCom 130 communications system. An Ethernet switch on the expansion module further enables applications featuring media convergence, such as the operation of a VoIP interface card M100-IP. It is possible to cascade two OpenCom 150 (rack version) units. Two ports of the Ethernet switch residing on the main module can be used externally. Two other ports are available for internal use with interface cards. With the OpenCom 131 no PBX cascading with another system is possible. However, PBX networking with a second infocom system is possible. 12
