ETSIEN 300 417-5-1 V1.1.3 (1999-05)91ScopeThe present document specifies a library of basic building blocks and a set of rules by which they are combined in orderto describe a digital transmission equipment. The library comprises the functional building blocks needed to completelyspecify the generic functional structure of the European digital transmission hierarchy. Equipment which is compliantwith the present document can be described as an interconnection of a subset of these functional blocks contained withinthe present document. The interconnections of these blocks should obey the combination rules given.

The CI isstructured to form a 2 928 bit long frame with 16 bit frame overhead containing 12 bit FAS, one bit RDI and a three bituser CI.NOTE 1:The bits for National Use (NU) in row 4, columns 2 to 4 of figure 2 are reserved for operator specificusage. Their processing is not within the province of the present document.P4e layer APThe AI at this point is a multiplexed signal containing four (728/2 928) ´ 139 264 kbit/s (see note 2) tributary signals(PU31) and (3/2 928) ´ 139 264 kbit/s (see note 3) user CI (NU) with co-directional bit timing and frame startinformation.NOTE 2:This equations equals a bitrate of 34 625,748 633 879 8 kbit/s.NOTE 3:This equations equals a bitrate of 142,688 524 590 164 kbit/s.The signal transported by an PU31 will be determined by the client layer application. Typical signals include:-a 34 368 kbit/s signal P31x_CI without an assumed structure and justification overhead bits;-a 34 368 kbit/s signal P31e_CI with a frame structure as specified in CCITT Recommendation G.751 [6] andjustification overhead bits;-a 34 368 kbit/s signal P31s_CI with a frame structure as specified in ETS 300 337 [9] and justification overheadbits.Figure 1 shows that more than one adaptation function exists in this P4e layer that can be connected to one P4e accesspoint. For the case of the adaptation source functions, only one of these adaptation source functions is allowed to beactivated. For this activated source, access to the access point by other adaptation source functions shall be denied. Incontradiction with the source direction, adaptation sink functions may be activated all together. This may cause faults(e.g. cLOF) to be detected and reported. To prevent this an adaptation sink function can be deactivated.NOTE 4:If one adaptation function only is connected to the AP, it will be activated. If one or more other functionsare connected to the same AP, one out of the set of functions will be active.SIST EN 300 417-5-1 V1.1.3:2003

Theframe overhead is defined as the first 16 bits of this frame as specified in CCITT Recommendation G.751 [6],subclause 1.5.2.RDI: This bit represents the defect status of the associated P4e_TT_Sk. The RDI indication shall be set to "1" onactivation of P4e_RI_RDI within 900 ms, determined by the associated P4e_TT_Sk function, and set to "0" within 900 ms on the P4e_RI_RDI removal.Frame Alignment Signal (FAS): The function shall insert the 139 264 kbit/s frame alignment signal (111110100000)into the frame overhead.Defects:none.Consequent actions:none.Defect correlations:none.Performance monitoring:none.SIST EN 300 417-5-1 V1.1.3:2003

A difference is takenas evidence of one or more errors (nN_B) in the block.RDI: The information carried in the RDI bit shall be extracted to enable single ended maintenance of a bi-directionalTrail (Path). The RDI (row 4, column 1) provides information as to the status of the remote receiver. A "1" indicates anRDI state, while a "0" indicates the normal, working state.
