Figure 3-61 STS-1 Selection
The aggregate bandwidth for the Turin Networks communication channel is:
192 kbits/s * 6 STS-1s = 1152 kbits/s
The TE-2020 supports selection of the management channel on a per STS-1 channel basis. The maximum
number of channels selectable is 12. The OC-192 PLM only supports provisioning of DCC on the first
STS-48 channels after muxing. Of those 48 channels, up to twelve can be selected.
Table 3-24 Default Line STS Selection for Management Communication
NOTE: EC1 STS-1 DCCs cannot be cross-connected.
The bandwidth calculation for bonded line DCC on an OC-48 PLM is as follows: D4-D12 represent 9
DCC bytes of 64 kbps channels for a bandwidth of 576 kbps. Then, the 576 kbps is multiplied by 12,
which represents the number of STS-1 channels to equal a combined bandwidth of 6.912 Mbps. When sec-
tion DCC is being utilized, the DCC channel is only on the first timeslot of the OC-N. The aggregate band-
width of section DCC regardless of optical rate is set to 192 kbits/s
The TE-2020 supports transparent DCC applications where the OC-n/nc interface between the non-Turin
Networks equipment and the TE-2020 is
• 1+1
• UPSR (terminated at the TE-2020)
• UPSR (not terminated at the TE-2020 for embedded ring transport)
