TDAT042G5 SONET/SDH
155/622/2488 Mbits/s Data Interface
Functional Description
Path Terminator (PT) Block
SPE Generate (continued)
The general rule for mapping STS-Mc frames in STS-N signals (M ≤ N) is that the TDAT042G5 can have a maxi-
mum of four normal pointers in STS-48 mode. For M ≤ 12, the valid starting locations for mapping into an STS-48
signal are 1, 13, 25, and 37. For M >12, only one normal pointer is permitted and it must start at the first location
(the first STS-1). The TDAT042G5 allows only one normal pointer in STS-3 or STS-12 modes. The only valid start-
ing location for mapping concatenated frames into an STS-3 or STS-12 signal is 1.
