Network Termination Equipment NTE1A

Application

Termination Interface for basic rate ISDN lines at customer premises.

Description

The NTE1A is a basic rate access ISDN network termination unit fitted at the customers premises which terminates the copper cable presenting the U interface from the local exchange and provides an S/T interface for connection of subscribers equipment.

ISDN basic rate access gives the user two B channels, each of 64kbps which may be used for transmission of speech and data and one D channel of 16kbps which is normally used for signalling.

Different types of user terminal equipment such as ISDN telephones, Group 4 facsimile machines, PC cards and ISDN PABX’s etc may be connected to the S bus up to a maximum of eight. An attached equipment may utilise one or both B channels. If one B channel is not busy it may be used by another equipment. The D signalling channel may be used by several attachments simultaneously.
