The TSBUS interface provides multiple asynchronous paths (all TSBUS frames run at
51.84 Mbps).
The supported TSBUS framer configurations that are mapped into and from VSPs are
as follows:
The supported TSBUS frame structures are DS0s, DS1s, E1s mapped via DS2,
VT1.5, VT2.0, C11, and C12.
The following mixed mappings are also supported by selectively configuring each
framer:
The frame structure is designed to transport the
• There are 28 PDH framers and 28 SONET/SDH framers. Either of these two

• DS0s extracted from mixed DS1s via the TSBUS
• DS1s and E1s extracted from mixed DS2s via the PDH framers
• DS1s and E1s extracted from mixed VTGs via the SONET framers
• C11s and C12s extracted from mixed TUG-2s via the SDH framers

implies. When using the SONET/SDH framers, they all have to be configured
as either SONET framers (one subcategory) or as SDH framers (the other
subcategory). The configurations of the SONET/SDH framers When
configuring for SONET subcategory of framers, each framer can be
independently configured as a VT1.5 framer or as a VT2.0 framer. The SDH
subcategory of framers is similarly configured. Each SDH framer can be
independently configured as either a C11 framer or an E1 framer.
