to its simplest form, MS and RS alarams pertain to physical level problem while AU, TU, VC are paths.
Synchronous Transport Module (STM) currently has levels 1, 4, 16, 64, 256 and 1024 where each level corresponds to a specific bit rate. The STM frame is considered as the basic transmission format for the Synchronous Digital Hierarchy (SDH) technology. These STM frames are byte-oriented arranged in a row and column manner.
SDH and PDH are two digital hierarchies in which different line speeds (e.g. E1, T1, STM1) are categorized.PDH (plesiosynchronous digital hierarchy) was replaced by SDH (synchronous digital hierarchy) due to its drawback in synchronisation where plesio refers to nearlysynchronous.E1, T1 and J1 are generally categorized under PDH. STM1, OC3, STM4, OC12 etc. are categorized under SDH.E1 is used worldwide nowadays in 2G technologies except North America and Japan (who are using T1 and J1 respectively). It is the line speed of 2Mbps. But how this speed comes along? The derivation is as follows.The audio signals were sampled and converted to digital signal at 64kbps, since 1960s for digital transmission of voice calls. When 32 channels (30 assigned for voice channels and 2 channels for framing and signaling), with each having speed of 64kbps are put together (or we call multiplexing), a line speed of E1, i.e. 2Mbps is produced by having 32 x 64kbps = 2.048Mbps.T1 line, which transmits at 1.544 Mbps can be interconnected with E1 for international use.Having 3 different speeds (E1, T1 and J1), PDH was later replaced by SDH in order to standardize the speed, making only 1 standard speed worldwide, which is STM1 having the speed of 155.52Mbps.

Alarms which are generated due to the failure of any link or card on the Sdh equipments are sdh alarms.
WHAT IS SDH
SDH = 3 times of SONET
In sdh radio 63 E1's are there
SDH sells fine, European linens, and has since 1986. Some popular SDH items include sheets, duvets, and bath towels. SDH also sells a line of luxury baby linens.
Alarms which are generated due to the failure of any link or card on the Sdh equipments are sdh alarms.
when we add LPOH to the to c's then the new thing is called VC(vertual container in sdh).
