Structured DS3 Configuration Guidelines

Planning and Ordering Guide

A Broadmore 1750 with OC-12c NIM can utilize Cell Buses A, C, D, and E and support up to 11 Structured DS3 ports within the available OC-12 ATM bandwidth of 622.080 Mbps.

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

To utilize the 1:N SAM protection feature, working SAMs are installed in slots C to N and the protection SAM is installed in slot P

NOTE: Configurations using more than four Structured DS3 SAMs require a high-capacity 3-fan tray for cooling. (Contact factory for details.)
