PEB3081HV1.4

Product Summary

The PEB3081HV1.4 is an ISDN Interface. It implements the four-wire S/T interface used to link voice/data ISDN terminals, network terminators and PBX trunk lines to a central office. The PEB3081HV1.4 is the successor of the SBCX PEB 2081 in 3.3 V technology. The PEB3081HV1.4 provides an S/T interface operating in TE, LT-T, LT-S, NT and intelligent NT modes, a serial control interface (SCI) for host programming, three general purpose I/O pins and one LED output which is capable to indicate the activation status of the S-interface automatically or can be programmed by the host.
