E1 tributary numbering (timslots) for SDH signals in KLM K describes TUG-3 group (1-3) L describes a TUG-2 group inside a TUG-3 (1-7) M describes a TU-12/VC12/E1 inside a TUG-2 (1-3)

The document discusses the multiplexing structure of Synchronous Digital Hierarchy (SDH) networks. SDH uses time-division multiplexing to combine lower-speed signals into higher bandwidth channels. The base transport module is the …

SDH is designed to transport isochronous traffic channels and is based on a hierarchy of continuously repeating fixed length frames. It has been designed to preserve smooth interworking with existing PDH networks and has adopted a synchronous frame structure that preserves the byte boundaries within the various traffic bit streams.

It maps 63 timeslots across 3 TUG systems to their corresponding VC-12, E1 and KLM identifiers, showing how the timeslots are distributed across the systems. Copy of SDH KLM Chart - E1 Numbering - Free download as Excel Spreadsheet (.xls), PDF File (.pdf), Text File (.txt) or …

I was a bit confused about the numbering scheme of TU12 within STM-1. to me. is the relation to KLM notation ? 2nd TU12 is KLM (?,?,?) and so on up to 63th TU12. reading a recommandation..;-) ). (Tributary#1 is TU12 1-1-1, Tributary#2 is 1-1-2, and so on). Is this. the rule I am looking for ? option 2) Table 7-1 specifies a "TS#=timeslot number".
