We tried to set the SFP port in autonegociation mode on the GSM-R BTS. On the remote router connected to our BTS we set the speed rate as 1000M.
As a result of this setting, the link between the BTS and router coulld not be established.
If we set the rate on the router to 100M, and the link comes up. The SFP port on the GTMUc supports 1000M.
We searched in the documentation and the GTMUC can support maximum 100M, this is why the link between the BTS and router could not be established at 1000M.
