Installation Manual

1027144–0001 Draft – Revision D.01
Commissioning the RT 7–19
RT installation
At this point, RT commissioning is complete, except for the RT to
HT tests described in section 7.8. You may or may not be able to
complete these tests, depending on whether or not other network
components are installed and operational. (See the test
requirements listed in section 7.8.)
Leave the RT powered on for testing and operation.
Perform the applicable tests described below if the newly installed
RT meets the listed requirements. If the RT/network does not yet
meet these requirements, perform the tests at a later time.
This test verifies the DS1 connection from the RT to the HT.
Requirements
The DS1 test described below requires the following:
• The RT must be fully installed, commissioned, and in
contact with the EMS through the hub.
• The HT must be operational and in contact with the EMS.
• DS1 services must be configured and provisioned.
• There must be no alarms present at the RT location.
• A loopback connector must be connected to the input/out
port of the patch panel, as illustrated in figure 7-8.
