ISDN Network Termination - NT 1 Telenet's ISDN Network Termination for basic rate access is the main gate to the world of ISDN. It enables subscribers to use services such as high-speed transmission of data, text and video signals in digital format over an access line in addition to voice transmission. It is a link between the subscriber line (U Interface) and the user interface to the network (S/T interface). A maximum of 8 terminal units can be connected to the S/T interface. The digital transmission format used offers the subscriber the possibility of access to two independent Basic Channels (B Channels) each with 64 Kbit/s and one 16 Kbit/s Signalling Channel (D), to be transmitted. The terminals connected to S/T for any two ISDN services can use both B channels simultaneously. The associated signalling information and various service features are transmitted over the D Channel. This results in a transmission speed of 144 Kbits/s for both transmit and receive direction. The NT1 is installed at the end of the public transmission line coming from the ISDN switch of the local exchange and converts the 2-wire duplex U interface into the 4wire double simplex subscriber S/T interface. Features: Upto 8 access sockets can be connected to the S/T interface via a 4-wire bus Two services like telephony and Data transmission can operate simultaneously. Data rate of 144 Kbps is available to the customer at the S/T interface. It has three bus configurations, which have different coverage ranges. i)Point to Point. ii)Point-to-Multipoint : Short passive bus. iii)Point-to- Multipoint : Extended passive bus. Has four operating modes depending on whether transmission is active or inactive and whether the integrated power supply is working or not. Echo cancellation at the U interface ensures that Data Signals are transmitted bidirectionally. The interface modules operate in the automatic mode. The U interface module recovers clock synchronization signal, monitor transmission errors and initiate appropriate reaction. In the event of a long-term short circuit, the power supply module is auto switched off and resumes operation automatically with only a delay of few seconds. The design is in compliance with ITU/CCITT/ANSI/ETSI and industry standard 2B1Q line code for the U interface. It is easy to install at the user's premises and can be installed in a wall-mounted cabinet or used as a desktop version. Testing and operation configurations can be adjusted quickly by means of switches and jumpers.

The Emutel series of ISDN Simulators provide a compact and cost effective solution to emulate the ISDN network to test and demonstrate all types of ISDN BRI and PRI CPE. Multiple ports allow generation of calls from one external CPE to the other with the flexibility of different protocol variants and interfaces. Different models are available to permit selection of the right number of ISDN BRI and PRI ports and flexibility to suite your budget.
