Mandatory Parameters Required For Establishing A Bts-Cpe Link; Read-Only Parameters Required For Monitoring The Link - Cambium Networks cnWave 5G Fixed Operation And Troubleshooting Manual

Figure 21:
Transmitted RACH Count – The Uplink Random Access Channel (RACH) is the uplink
l
channel used by the CPE to initiate a connection request to the BTS. If all is well, the BTS
must respond to enable the CPE transmission that results in generating a RACH number.
With this RACH number, there are also two other counters - Transmitted SRB and Received
SRB packets. These numbers indicate the number of BTS-CPE messages exchanged to
attach the CPE. At this point, this means that the CPE can find the BTS, and baring any
other radio issues (as shown in

Mandatory parameters required for establishing a BTS-CPE link

Table 1 lists the parameters that must be configured to establish a link between a BTS and one or several
CPEs.

Read-only parameters required for monitoring the link

There are read-only parameters that must be monitored during troubleshooting if a link between a BTS
and a CPE cannot be established.

Description
It is recommended to have the same label for the
operational software. Example: 3.0 label for the 3.0
operation software.
The CPE must have the same frequency in the Radio
Scan Frequencies list as that of the BTS.
Must be the same for both BTS and CPE.
Must be the same for both BTS and CPE.
Must be the same for both BTS and CPE or can be set
to Auto Detect for the CPE In C100 UI
(recommended).
