Description:

SDH-TO-PDH FRAMER/MAPPER

Features

* VT Mapper PRELIMINARY REV. P1.0.5 SDH-TO-PDH FRAMER/MAPPER WITH INTEGRATED 21-CHANNEL E1 SH LIU
* Maps up to 21 synchronous or asynchronous E1 signals to SDH AU-3 via TUG-2 and TU-12, or to SDH STM-0 payload capacity via VT Groups and VT2.
* Dynamic VT/TU size selection.

Applications

* The device generates and terminates all SDH Regenerator Section, Multiplexer Section and Path Overhead including the low-order Virtual Container (VC) Path Overhead. E1 framing is transparent; therefore, the device neither generates nor terminates the E1 frame. FIGURE 1. SIMPLIFIED BLOCK DIAGRAM SDH
