Description
E1Mx16 Device E1 Mapper 16-Channel TXC-04216 DATA SHEET .
The E1 Mapper 16-Channel device is designed for add/drop multiplexer, terminal multiplexer, and dual and single unidirectional ring applications.
Features
* Add/drop sixteen 2.048 Mbit/s signals from an STM-1 VC-4/AU-3, STS-3, or an STS-1
* Independent add and drop bus timing modes
* Selectable HDB3 positive/negative rail or NRZ E1 interface. Performance counter provided for illegal coding violations.
* Digital desynchr
Applications
* Four field-proven QE1M Quad E1 Mapper chips are interconnected in a single compact package to permit higher application board densities. Sixteen E1 2.048 Mbit/s signals are mapped to and from asynchronous Tributary Unit-12s (TU-12s) or Virtual Tributary 2s (VT2s). The E1Mx16 interfaces to a multipl
