The ISDN BRI interface is a User-Network Interface (UNI). It has an asymmetric behavior. The two sides are denominated by NT and TE. TE ports Are found on ISDN Terminals (ISDN phones or PBX trunk ports) NT ports Are found on the NT (Network Termination) box. An NT port always connects to a TE port and vice versa. The pinout of the ports is such that you can use straight cable to connect to the respective ISDN equipment. | |
