Unstructured DS3-3/E3-3 Configuration Guidelines
Unstructured DS3-3/E3-3 Configuration Guidelines
A Broadmore 1750 with OC-12c NIM can utilize Cell Buses A, C, D, and E and
support up to 11 unstructured DS3 or 12 unstructured E3 ports within the available
OC-12 ATM bandwidth of 622.080 Mbps.
Because each unstructured DS3-3 and E3-3 SAM has three ports, only one SAM is
needed for each cell bus. However, to utilize the 1:N SAM protection feature, all
SAMs must be identical and be installed in specific slots.
For NIM redundancy, install OC-12c NIMs in slots A and B
If a single OC-12c NIM is used, it should be installed in slot B
Working SAMs must be installed in slots C, F, J, and M, corresponding to cell
buses C, D, E, and A, respectively
The Protection SAM is installed in slot P
