Configuration
NIM Redundancy
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.
1:1
Protection 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.
