TDAT SONET/SDH
155/622/2488 Mbits/s Data Interfaces
Introduction
The TDAT data interface is available in three different configurations as summarized in Table 1.
TDAT04622
The TDAT04622 device contains a subset of the TDAT042G5 device. The TDAT04622 device functions as
described in the
TDAT042G5 SONET/SDH 155/622/2488 Mbits/s Data Interface Data Sheet
(DS98-193SONT-4) with the following limitations:
s
s
Quad OC-3 operation only or single OC-12 operation only.
Single UTOPIA port.
TDAT021G2
The TDAT021G2 device contains a subset of the TDAT042G5 device. The TDAT021G2 device functions as
described in the
TDAT042G5 SONET/SDH 155/622/2488 Mbits/s Data Interface Data Sheet
(DS98-193SONT-4) with the following limitations:
s
s
Quad OC-3 operation only or dual OC-12 operation only.
Two UTOPIA ports.
TDAT042G5
The TDAT042G5 device contains all functionality as described in the
TDAT042G5 SONET/SDH 155/622/2488
Mbits/s Data Interface Data Sheet
(DS98-193SONT-4).
