8PSTUStartup
This chapter describes the initial configuration of the Packet-Switched
Termination Unit (PSTU). All activities in this chapter can be performed on-site.
Some activities can also be performed in-house. The default is to perform all
activities on site, which is how they are described in this chapter. For further
information regarding the activities that can be performed in-house, see Section
8.2 Work Process for PSTU Startup on page 150.
When an RBS 2308 is configured with a PSTU for IP-based transmission, a
maximum of four Transceivers (TRX) can be used.
The PSTU is in remote operation after startup, which means that it has an
Internet Protocol (IP) address, the IP stack is in operation, and the PSTU can
be remotely operated from the Operations Support System (OSS). Further
configuration is required from the OSS to enable the PSTU to carry traffic.
Note that the instructions in this chapter include information about the optical
Ethernet interface that is not supported in the first software release.
