■ external voice mail systems.
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 regar-
ding the connection of analogue devices. Devices not mee-
ting 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 SYS Configuration: Components menu. For details, refer to the online Help.
Please note: Use only devices with an input impedance of 600 ohms, floa-
ting 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 S
0
ports. For both port types the voice mail system can activate the notifi-
cation for system terminals with the code procedures
*68 resp. #68.
