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 STM-1 with a transmission rate of 155.52 Mbps. Higher rates are multiples of the STM-1, such as STM-4, STM-16, and ...

The document shows a mapping between timeslots in different systems. 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.

2022年4月28日 · KLM is nothing but a notation system by which a channel is identified at any SDH/PDH node. Within a SDH network it is important to be able to assign channels to different pathways to allow...

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.

KLM Numbering. Within a SDH network it is important to be able to assign channels to different pathways to allow correct routing of information. This means that an engineer must be able to identify specific channels at any network node. For example a 2.048Mbit/s tributary may be required to be outputted on a SDH aggregate from a Nortel TN- 4XE ...

2008年10月16日 · paragraph 7.3.9 and Appendix II ): this KLM to column mapping is clear to me. What is not clear, is how TU-12 can be numbered from 1 to 63, and what is the relation to KLM notation ? That is, I...

2022年7月29日 · Synchronous Digital Hierarchy (SDH) and Synchronous Optical Network (SONET) are standards used to transmit voice and data over fiber optic networks using synchronous time-division multiplexing. SDH defines a base transmission rate of 155.52 Mbps (STM-1) while SONET uses OC-1 at ~51 Mbps.
