AMR on E1 BTS with tw-e1abis-mgw
by Mychaela Falconia 08 Dec '25

08 Dec '25

Hello Osmocom community, I am pleased to announce that my new E1 Abis MGW (replacement for the limited E1 Abis function in osmo-mgw) now supports AMR speech codec, in addition to FR/HR/EFR and CSD: https://gitea.osmocom.org/themwi/tw-e1abis-mgw Basically compile it from source following instructions in the README file, run it alongside with all of the standard Osmocom components, and enjoy the addition of AMR and CSD capabilities - if you have E1 BTS hardware, that is... (For those not familiar with E1 BTS support in Osmocom, the E1 Abis MGW function of osmo-mgw supports FR/HR/EFR, but not AMR or CSD.) I realize that this news item may not be of much interest to most people nowadays, simply because almost no one uses the combination of Osmocom CNI stack with E1 BTS hardware any more. However, there is little in the way of hardware alternatives: if someone wishes to operate a traditional high-power, high-capacity GSM cell site (typical 3-sector geometry, high Tx power, multiple TRXs per sector for decent capacity), I am not aware of any publicly available hardware that can achieve this job in the "modern" way of SDR etc. Hence finding old Ericsson or Nokia BTS hardware on the surplus market, just old enough to still offer E1 interface as an option, is the only practically available choice for a professional-quality cell site with Osmocom software stack from the BSC up. And why does it have to be E1, why not more "modern" hw from the same Ericsson/Nokia/etc that still supports GSM, but only with IP interfaces? Answer: those IP interfaces are proprietary, and we have no docs - or at least I don't. OTOH, E1 is highly standardized, and for those parts that differ per vendor, our little community already has the necessary knowledge... I will now be preparing some patches for osmo-bsc and its underlying libosmo-mgcp-client to support switching on TW-TS-006 and TW-TS-007 RTP enhancements in the E1 Abis MGW when the CN requested them via BSSMAP extension of TW-TS-003, and then I will need to get back to work on CN software, namely a more proper MSC. I now have a new modular architecture in mind, in which osmo-msc will be just one component of what I consider to be the MSC as a whole. osmo-msc will need some patches in order to work with a different MGW (one that transcodes to G.711) and some MNCC changes, but I'll implement them in such way that all functional changes will be enabled either by vty config or by bits set in MNCC struct by external MNCC sw, so those patches will stand a chance of being mergeable. But the part with osmo-msc patches is still far away... GSM/2G Forever, Mother Mychaela

osmo-trx-ms documentation

Hello. I'm looking for a replacement for grgsm_trx, and I came across osmo- trx-ms in the osmo-trx repository. But I came across a lack of information about this project. You can find out its status and whether it is recommended to use it in principle as a Front-End SDR for osmocom-bb mobile.

cmd2 update causing pySim-shell to fail
by bryan coxwell 08 Dec '25

08 Dec '25

Hi all, Just wanted to share an issue and a quick workaround I found for it in case anyone else has the same problem. I believe a cmd2 update is causing pySim-shell to fail. After installing it on a fresh install of Ubuntu Server 20.04 and getting the following error when I run "python3 pySim-shell -p0": >Using PC/SC reader interface >Autodetected card type: sysmoUSIM-SJS1 >AIDs on card: > USIM: a0000000871002ffffffff8907090000 >Traceback (most recent call last): > File "pySim-shell.py", line 512, in <module> > app = PysimApp(card, rs, opts.script) > File "pySim-shell.py", line 59, in __init__ > super().__init__(persistent_history_file='~/.pysim_shell_history', allow_cli_args=False, use_ipython=True, auto_load_commands=False, command_sets=basic_commands, >startup_script=script) >TypeError: __init__() got an unexpected keyword argument 'use_ipython' If you run into this you can fix it by uninstalling cmd2 and reinstalling cmd2 with "pip3 install cmd2==1.5". Best, Bryan

How to Effectively Prepare for the Oracle 1Z0-1127-25 Exam in Minimal Time
by mahmad.iworks＠gmail.com 03 Dec '25

03 Dec '25

Facing a certification exam can feel daunting, especially when time is short. The Oracle 1Z0-1127-25 exam tests a wide range of skills and concepts, requiring both conceptual understanding and practical application. However, with a structured approach, you can study efficiently and make the most of your available time. A good first step is to familiarize yourself with the official exam objectives. Oracle provides a detailed outline of the topics and skills assessed in the 1Z0-1127-25 exam. Breaking the syllabus into smaller, manageable sections allows you to prioritize areas that need the most attention. Start with high-weightage topics and ensure you have a strong understanding of core concepts before moving on to the more advanced material. Next, combine different study resources for a balanced approach. Textbooks, official documentation, and online tutorials are essential for conceptual clarity, but incorporating practice materials is equally important. Many candidates find Oracle <a href="https://www.pass4future.com/oracle/exam/1z0-1127-25">1Z0-1127-25 Exam dumps</a> helpful for familiarizing themselves with question patterns and time management. While these dumps should never replace proper study, they can highlight commonly tested areas and help simulate real exam conditions. Active learning techniques can also save time and improve retention. Creating quick notes, flashcards, or mind maps for complex topics allows for rapid revision. Additionally, scheduling short, focused study sessions, rather than long, unfocused hours, can boost concentration and prevent burnout. Finally, practice consistently. Even in minimal time, attempting mock tests regularly helps track progress, identify weak spots, and build confidence. Review mistakes carefully to ensure you don’t repeat them in the actual exam. By combining clear planning, strategic use of resources like Oracle 1Z0-1127-25 Exam dumps, and consistent practice, it is possible to prepare effectively even with limited time. Remember, the quality of study often outweighs quantity.
