General information

Mapping/Demapping
The PDH tributaries are mapped into a STM-1 signal via the AU-4 or the AU-3 layer.
Container contents for all mapping options:
• Framed or unframed PDH test signal in one selected container
(6 Mbit/s, unframed only)
• PDH multiplex signal in one selected container
(together with Mux/Demux Chain 64k/140M or M13 option)
• Filling one selected container with a test pattern without justification bits
(Bulk Signal to O.181)
Drop & Insert
An additional Drop & Insert Option (BN 3035/90.20) for dropping or inserting tributary signals
(via sockets) is available in conjunction with the mapping options.
