Change in osmo-hnbgw[master]: mgw_fsm: add MGW support to osmo-hnbgw
by dexter 24 Feb '22

24 Feb '22

dexter has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-hnbgw/+/26795 ) Change subject: mgw_fsm: add MGW support to osmo-hnbgw ...................................................................... mgw_fsm: add MGW support to osmo-hnbgw osmo-hnbgw lacks support for an co-located media gateway. This makes it virtually impossible to isolate the HNB from the core network properly. Lets add MGCP support to osmo-hnbgw so that it can control a co-located media gateway to relay the RTP streams between HNB and core network.

Attention is currently required from: manawyrm, laforge. Hello Jenkins Builder, laforge, tnt, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-e1-hardware/+/27317 to look at the new patch set (#2). Change subject: manual: add info and renders to show to set TE/NT mode ...................................................................... manual: add info and renders to show to set TE/NT mode The page break is currently a bit ugly, but I didn't see an easy way to fix it. The images and info text should make the process much clearer.

Because it's all taken care of in https://gerrit.osmocom.org/c/osmo-e1-hardware/+/27316 already with a slightly more extensive explanation. So just leave this section about the "how to change mode". -- To view, visit https://gerrit.osmocom.org/c/osmo-e1-hardware/+/27317 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: osmo-e1-hardware Gerrit-Branch: master Gerrit-Change-Id: I5999dc60850da2cd02d9bbc7db5727cdebf041c6 Gerrit-Change-Number: 27317 Gerrit-PatchSet: 1 Gerrit-Owner: manawyrm <osmocom.account(a)tbspace.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: laforge <laforge(a)osmocom.org> Gerrit-Reviewer: tnt <tnt(a)246tNt.com> Gerrit-Attention: manawyrm <osmocom.account(a)tbspace.de> Gerrit-Attention: laforge <laforge(a)osmocom.org> Gerrit-Comment-Date: Thu, 24 Feb 2022 08:06:16 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Gerrit-MessageType: comment
