ANT-20/ANT-20E STM-1 mapping

Specifications S-1

Specifications

These specifications apply to the options:

STM-1 Mapping

for ETSI tributaries

for ANSI tributaries

1 STM-1 Mapping

1.1 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.
