Ericsson BFYBS 10101/1 Door Interface Unit

To connect to an Intercom (e.g. and Aiphone IE-JA):
-Disconnect loudspeaker from the circuit board and connect direct to the Door Interface Unit (DIU) LS connector. There does not seem to be a polarity for the speaker.
-Disconnect the Switch from the circuit board and connect direct to the BELL connector on the DIU.
-Leave microphone connected to circuit board and connect the input of the intercom (back panel of intercom) to the MIC connector of the DIU. This allows the built in audio transformer of the intercom to be used by the microphone.
-Connect the extension to Ext A, program as a hotline and test.

Unified Messaging

An amazing feature - causes late nights, high blood pressure and depression. When it works though, BEAUTIFUL! However, the built-in fax server is a nightmare (probably 'cos it is my debut installation). So, for other first-timers, note the following:

1. Use an external Fritz modem (has to be a Fritz modem).
2. The fax number must exist in the user's setup.
3. The system must receive CLIP.
4. Fax services must be installed. (Ensure the Ericsson Fax plug-in on the client's side has receive enabled.
5. XP must have SP3 for the plugin to work.
6. SUMS can be setup with only a fax number and no assigned extension. However, the setup can not be edited and should a problem occur, delete and recreate.

Note: You can not do a loop test from the one channel into the other channel on the same modem. For best results, adhere to the above pitfalls and set it up on the clients exchange with DID.


Enjoy the setup!

Ericsson CCA

So I have this call centre I have to setup with all the bells and whistles...except for an IPU. Yup, all connection to the PABX is via V.24 - bear in mind this is CCS and BLink, therefore each of them require a V.24 connection. If you are having difficulty setting up the BLink part, have no fear as there is a discrepancy between the documentation available. Setup that worked with me (CPU-D5, R16):

11: O&M Centre with RASC and MS or CTI
1: US-ASCII
19200 baud
0: Master
CTI

Also while setting up CCA, I could not get it to read the CCS database - I was pointing it to the wrong directory. Make use of the directory C:\Program Files\Ericsson\CCSv4\Config.

Ericsson BP Hotel

In setting up a recent site for a Hotel, using a Ericsson BP250, I discovered that the hotel phones were not barred during check in/out. The procedure completed successfully, but the extension remained open despite being checked - out. The setup of the PABX had the extensions setup as guest phones - no joy. In the end, the operator had been adjusted to 4777. By changing the operator to 9 I managed to get the call barring to work. Further experimenting proved that the operator (not the SWB!) had to be 9. Any other number and call barring with check in/out does not work.
