Configuration

NIM Redundancy

Protection	component has a dedicated backup, which assumes
	operation if the primary unit fails, so that connectivity is not
	adversely impacted.

NIM Redundancy

ATM redundancy is provided by installation of a second NIM. The Broadmore 1750 can then be configured to provide 1+1 or 1:1 NIM protection in accordance with the SONET-GR-253-CORE specification. The APS is per the SONET-GR-253-CORE specification. The user may select either reverting or non-reverting APS modes as explained in the configuration below.

NOTE: The Broadmore will display only those features supported by the installed NIM. Consequently, some of the features described below may not apply to the NIMs you are configuring.

Configure redundancy following steps on the next page.

1.Review the hardware configuration. The Broadmore 1750 must have two NIMs installed to support redundancy, the master NIM in slot “B” and the APS NIM in slot “A”. If installing 1:1 protection, reverting or non-reverting, contact the ATM switch vendor to ensure that 1:1 protection is supported.
