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. 

Add setcap so dnsmaq can be used. 

$ ip link set dev slaptapX up

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 (FDD) (instead of Theia Runner) on your slapos-node installed BBU.
2. Refer How To Request A Service On A Specific Computer to request ORS (FDD) (instead of Theia Runner) on your slapos-node installed BBU. 
   • Software Type: select "eNB"
   • RRH: select "Lopcomm ORAN"
   • DL EARFCN: 300
   • dnsmasq: true
   • RRH MAC address: input your RRH MAC address, so the RRH can get the IP from dnsmasq
   • cpri_rx_delay: 25.11
   • cpri_tx_delay: 14.71
   • cpri_tx_dbm: 63

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.
