PTP 800 Series User Guide Task 6: Configuring protection
phn-2513_004v000 (Oct 2012)
6-55
Before upgrading existing links from unprotected to protected, complete the following
prerequisites:
• Configure the new CMUs as primary or secondary units by setting the Primary
Secondary Mode attribute.
• For a new primary CMU, ensure that wireless transmission is disabled by selecting
Mute Transmitter. This prevents possible interference with the existing operational
unit.
• Attach ‘Primary” or ‘Secondary’ labels as appropriate to the new CMUs.
• Set Fault Protection Switching to ‘Disabled’. This prevents fault protection switches
occurring during installation.
To configure protection, proceed as follows:
1
Select menu option System, Configuration, Protection. The Protection
Configuration page is displayed (Figure 136).
2
If the Transmitter attribute is set to ‘Enabled’, there may be a safety
requirement to disable wireless transmission. If so, select Mute Transmitter.
The Transmitter attribute changes to ‘Muted’.
3
Depending on whether Receive Diversity is required, set the Primary unit
protection attribute to either ‘Hot Standby 1+1’ (Figure 137) or ‘Hot Standby
1+1 with Rx Diversity’ (Figure 138).
4
Repeat at the Secondary unit (Figure 139 or Figure 140):
5
Review and update the Protection Configuration attributes (Table 231).
6
Select Submit Updated configuration.
