Carrier Access 1750 Benutzerhandbuch

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.

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.

A special case of 1:n protection where n=1. Each critical 
component has a dedicated backup, which assumes 
operation if the primary unit fails, so that connectivity is not 
adversely impacted.
