Node Protection Configuration
For Link
hot-standby and diversity configurations, two RAC plug-ins of the
same type are required to provide protection, with one assigned as the primary,
and the other secondary.
For Link
dual protection configurations four RACs are required for subordinated
protected/protected links, or three RACs for protected/non-protected
installations. Each of the subordinated protected links are configured as standard
hot-standby or diversity links, but while both must be configured for the same
capacity each can be on different channel bandwidths and/or frequency bands.
Similarly for a subordinated protected/non-protected link pairing.
For Ring
the east west pairings may be RAC/RAC, RAC/DAC 155oM, or DAC
155oM/DAC 155oM. DAC 155oMs are used where fiber linking is required to
close a ring.
For Tributary
protection, two DAC plug-ins of the same type are required to
provide protection, with one assigned as the primary, and the other the
secondary.
Node Protection Operation and Rules
This section provides data on the basic 9500 MXC link and data protection
options. For additional data on dual protection and 1+1 ring protection refer to:
• Additional Rules for Dual Protection on page 8-6.
Additional Rules for 1+1 Ring Protection on page 8-7
1. Two partner plug-ins must be installed in the Node; it is not possible to
configure a protected link without both.
• For a protected Link, two RACs of the same type must be installed.
From one Node/Terminal you can launch CT screens for its immediate remote
partner(s) by right-clicking on the relevant RAC or DAC 155oM within a LINK,
RING or DATA module (applies to all module-based screens such as System
Summary and Plug-ins), and selecting the Launch Remote option (requires an
operational connection to the remote end).
