ISDN Network Termination Device
Model: NT1
- Two-way transfer (4 wires) towards the user installation (S/T interface)
- Remote power supply to the terminal from the exchange (in case of AC power outage at the user's premises the remote terminal can be configured for telephone service)
- Transfer of 4.5W from the 220V mains to the S/T interface for remote power supply to the terminals
- Galvanic insulation between the user line pair, S/T interface and the AC mains
- Protection against excess voltage on the user pair, the S/T interface and the 220V power supply
The NT1 is used as a network termination for basic access to ISDN networks and features 2-channel transmission at 64 Kbit/sec and single channel transmission at 16 Kbit/sec (2B+D) on a single line pair. The NT1 makes it possible to connect up to 8 ISDN terminations (TE) on the S/T interface, while the terminations themselves can be powered by a 220V internal power unit connected to the mains. The device is ETSI 300012 and CCITT I 430 compliant as concerns the technical specifications of the S/T interface (level 1), as well as TS 102 080 and CCITT G961 compliant as concerns the electrical specifications of the U interface.
