27. see figure 2 2 TPR 4 intermediate multiplexer TPR 5 path back up see figure 2 3 TPR 6 flexible multiplexer TPR 1 Switch of Streams This type of operation enables transmission of protected E1 external signal in parallel over two separate transmission paths and choice of a signal from the better quality path by the receiving end TPR 2 Terminal Multiplexer Basic application that connects channels from the channel units placed in identical positions of opposite stations 4 C405S970 950 14 N02 TPR 3 Redundant Multiplexer Transmission of the 2Mbps stream local signal from channel units over two separate paths In the basic setting the whole stream is doubled but it is also possible to select function using CC which allows for redundancy of only the selected 64 kbps channels TPR 4 Intermediate Multiplexer An equipment variant with two external directions enabling termination of selected channels and transiting of the others Channel selection can be changed by control system command The equipment can be included in a redundant ring with automatic channel redirection in case of failure of any section TPR 5 Path Backup Redundant operation of two paths realized with PCM30U OCH Both ends are interconnected by a cable transmitting 2 Mbps signals and PHO failure message One of both paths is set as main one by means of jumper in CJAB whereas the other one as redundant CJAB units in both ends evaluate
28. transmission of two telephone channels the EM4P and EM2P units are used for 4 wire and 2 wire transmissions respectively These units can also be used for the transmission of other voice band signals such as those of modems or voice frequency carrier telegraphy DORIS 2000 NET software the management system of PCM30U OCH equipment is a universal management system designed for all transmission systems manufactured by TTC In the network of mutually connected PCM30U OCH PCM30U stations the management channel is transmitted in the S4 service bit of the KIO channel interval The management channel is in every PCM30U OCH equipment terminated by the M interface that within one locality enables management interconnection of those PCM30U PCM30U OCH devices not being interconnected by 2 Mbps streams Anywhere in the network is it possible to connect the RJ control unit for the controlling of max 64 network elements represented always by a CJAB unit to the M interface The DORIS management system is compatible also with the former version of central units using the TJ telemetric units The RJ unit as the M interface Q interface converter mediates connection to the PC serial port The DORIS SERVICE program enables local management of one PCM30U OCH equipment the DORIS 2000 NET network management of up to 32 local RJ control units and theoretically up to 254 local and remote RJ units per one DORIS interface As for the power distributing netwo
