Installation Connectible Terminals Additional a/b ports can be provided by installing interface cards (on an OpenCom 130 / 150). Please note: Adhere to the following notes and recommendations regarding the connection of analogue devices. Devices not meeting the technical requirements of the OpenCom 100 can cause damage to it. Analogue Telephones If analogue telephones are to be used, we recommend the use of devices featuring voice-frequency (VF) signalling, as the additional features of the OpenCom 100 cannot be used with pulse dialling. Modems The maximum transmission rate for analogue modems is 33.6 kbit/s (V.34+). Music on Hold A suitable external device for music on hold is the Genius 2000, manufactured by Speech Design. If you do not operate an external MoH device, the OpenCom 100 offers an internal MoH, which you can load in the Web console Configurator in the System: Components menu. For details, refer to the online Help. Please note: Use only devices with an input impedance of 600 ohms, floating connection, for external music on hold. Incorrect input impedance can cause irreparable damage to the OpenCom 100. Voice Mail If you are using an external voice mail system, it must be capable of handling the number of digits used for internal telephone numbers, e.g. five digits if you have configured five-digit internal numbers. We recommend the following Speech Design products: Memo 200 / 300 / 400 or Memo 200-A / 300-A / 400-A. The external voice mail system can be connected to internal a/b ports as well as to internal S0 ports. For both port types the voice mail system can activate the notification for system terminals with the code procedures *68 resp. #68. Intercom System (for a/b) The intercom systems "DoorLine T01 / 02" and "DoorLine T03 / 04" of the Deutsche Telekom can be connected via the "DoorLine M06" to any a/b port. The "DoorLine" module provides the actor for the door opener contact. 57
