BVV-105: E-mail-SMS-Gateway
BVV-105 Is a small, DIN-rail mountable device, which works as a local SMTP-server i.e. e-mail server. This means, that it can receive e-mail messages locally, and relay them as text messages (SMS) through serially connected GSM-modem.
In typical usage, BVV-105 receives email message (usually alarm message) from building automation controller , converts message to SMS message, and sends it to receiver.
Receiver messages can also be relayed to smtp-server, to be delivered as emails.
Configuration and commissioning is performed through web-based user interface.
NOTE! For sending SMS messages to GSM network, BVV-105 needs working GMS-modem like Cinterion BGS2T attached to it. 
How does it work?
BVV-105 (a.k.a. Viesti-Vertti) works as local MTA (mail transfer agent), also known as email server. It means, that it functions as local SMTP server, then it identifies messages which has numerical local-part (a.k.a mailbox or username) - that is the address part before the '@'-symbol. Then it sends them as text messages (SMS). Messages with regular receiver email address it relays to configured SMTP server, and forwards as regular email messages.

Modem status LED (2G-modem: BGS2T)
The orange status LED of BGS2T can help with troubleshooting: Usually the SIM card (or cellular service subscription) is at fault if the LED is blinking in the Limited Network Service mode (600 ms on/600 ms off). In this case a more specific error code can be read from the SMS Daemon log (a reboot of BVV-105 may be required to show the log at the beginning).
Normally the LED should blink in the IDLE mode (75 ms on/3 s off).
