This tutorial  explains how to set up Rapid.Space BBU with Lopcomm RRH via CRPI

The Lopcomm RRH used for the tutorial is xxx (Model name); The CPRI card used in the Tutorial is from Amarisoft

Re6st verification:

Make sure you have re6st installed to install SlapOS. Here is the verification of slapos:

$ slapos

usage: slapos [--version] [-v | -q] [--debug] [--log-file LOG_FILE] [--log-color] [--log-time] [-h]

SlapOS client 1.7.13

optional arguments:
  --version             show program's version number and exit
  -v, --verbose         Increase verbosity of output. Can be repeated.
  -q, --quiet           Suppress output except warnings and errors.
  --debug               Show tracebacks on errors.
  --log-file LOG_FILE, --logfile LOG_FILE, --log_file LOG_FILE
                        Specify a file to log output (default: console only)
  --log-color           Colored log output in console (stripped if redirected)
  --log-time            Include timestamp in console log
  -h, --help            show this help message and exit
 

Test the licences by launching lte. 

Make sure slapos has been properly installed. Run the script to install the ORS playbook:

$ wget https://deploy.erp5.net/ors && bash ors

1. Refer How To Supply A Software To A Computer to supply ORS (TDD 1900) (instead of Theia Runner) on your slapos-node installed BBU.
2. Refer How To Request A Service On A Specific Computer to request ORS (TDD 1900) (instead of Theia Runner) on your slapos-node installed BBU. 
   • Software Type: select "eNB and EPC"
   • RRH: select "Lopcomm ORAN"
   • DL EARFCN: 300

Note: Although the ORS is now marked as TDD 1900, it can also be used for FDD Band1 (DL EARFCN: 300). These options will be removed in the future. 

Amarisoft configuration for Lopcomm RU is integrated with Rapid.Space panel. 

The CPRI lock should arrive as soon as the service is deployed, meaning the U-plane work by then. 

The automation of M-plane is not yet perfectly done, such as DHCP server is still needed, a temporary patch is needed for netclient. These will be fixed soon.
