The ID-90 is an ISDN-adapter designed to meet industry's demands on reliability and functionality in exacting environments with high levels of interference. The ID-90 with V.90 option allows communication against analogue modems over the ISDN. 

It supports both European standards, Euro DSS1 and VN4 ISDN (French). Equipment with RS-232/V.24 or RS-422/485 interfaces can be connected to the adapter. Data can be sent on both the B- and D-channels at speeds up to 128 kbit/s. On the serial side speeds of up to 115.2 kbit/s can be handled. ID-90 supports all standardised ISDN-protocols including HDLC-transparent, X.75,V.110,V.120, X.31 D-channel, PPP and ML-PPP. The unit is easy to configure by using DIP-switches or software commands (AT, X3-PAD and CAPI 2.0). ID-90 has four alarm inputs that can send an SMS message of 20 characters to a pre-programmed number through external "triggering". Also features the possibility of a secure connection using a password, recall and dial-back. The modem is designed to fit on an 35 mm DIN-rail.The DIN-modem is attached and secure in a single action.

Option V.90

The ID-90 with V.90 option allows communication against analogue modems over the ISDN. ID-90 V.90 connects to an ISDN S0 and can communicate to remote analogue modems as well as ISDN-adapters. ID-90 V.90 option handles ITU-T modulation principles from V.21 to V.90 on the analogue side. All other functionality is the same as the standard ID-90.
