IMHO, this amount of logging is only suitable for development stage. For a regular user/customer trying to understand what's going on it's too verbose.

https://gerrit.osmocom.org/c/osmo-bts/+/22888/1/src/common/l1sap.c 
File src/common/l1sap.c:

https://gerrit.osmocom.org/c/osmo-bts/+/22888/1/src/common/l1sap.c@938 
PS1, Line 938: DL1C
Pau was complaining about unreadable DL1C (https://osmocom.org/issues/5007), maybe DL1P?
The 'L1C' stands for "Layer 1 Control", 'DL1P' stands for "Layer 1 Primitives".

PS1, Line 938: DL-FACCH repetition: repeating FACCH channel
How can you 'repeat FACCH channel'? You actually repeat a 'FACCH block', or more precisely 'retransmit' it.


https://gerrit.osmocom.org/c/osmo-bts/+/22888/1/src/common/l1sap.c@943 
PS1, Line 943: channel
Same here.


https://gerrit.osmocom.org/c/osmo-bts/+/22888/1/src/common/l1sap.c@994 
PS1, Line 994: 		LOGPLCHAN(lchan, DL1C, LOGL_DEBUG, "DL-FACCH repetition: disabled by BSC\n");
This looks redundant to me, if it's disabled that I would not expect any logging.


https://gerrit.osmocom.org/c/osmo-bts/+/22888/1/src/common/l1sap.c@1044 
PS1, Line 1044: 	if (rxqual >= upper) {
How about storing the current 'repeated_dl_facch_active' value and logging only if it changes from true to false and vice versa?


https://gerrit.osmocom.org/c/osmo-bts/+/22888/1/src/common/l1sap.c@1066 
PS1, Line 1066: 		LOGPLCHAN(lchan, DL1C, LOGL_DEBUG, "DL-SACCH repetition: MS does not request DL-SACCH repetition (SRR=0)\n");
This also looks redundant, and would probably make 'DL1C' unreadable.


https://gerrit.osmocom.org/c/osmo-bts/+/22888/1/src/common/l1sap.c@1083 
PS1, Line 1083: channel
block


https://gerrit.osmocom.org/c/osmo-bts/+/22888/1/src/common/l1sap.c@1091 
PS1, Line 1091: 
ws, unrelated


https://gerrit.osmocom.org/c/osmo-bts/+/22888/1/src/common/l1sap.c@1468 
PS1, Line 1468: 		LOGPLCHAN(lchan, DL1C, LOGL_DEBUG, "UL-SACCH repetition: disabled by BSC\n");
Same here.
