FiOS & PONs

by Chuck Anderson

As a followup to a discussion we had after the WLUG meeting, here are some good pages to read about how FiOS works. Verizon is using Passive Optical Networking, either BPON or GPON depending on the CO. The downstream side is shared, since by its very nature a PON's downstream direction is broadcast on a single wavelength--the light goes from the OLT to every customer's ONT on the PON "tree". For privacy each customer's downstream traffic is "encrypted" so only the intended ONT/customer can decrypt it. The upstream side is shared via TDMA since only one customer's ONT can trasmit at a time on the single upstream wavelength "up the tree" towards to root of the PON where the OLT lives...each ONT gets a "time slot" for upstream transmissions. There can be up to 32-128 customers shared on a single PON. http://www.dslreports.com/faq/verizonfios http://en.wikipedia.org/wiki/Optical_Line_Termination

Re: [Wlug] Talk for April...

by James Gray

I'd like to hear more about ZFS. As you know there was a previous presentation on ZFS as well, so it would be nice to cover some new ground. I'd like to see some ZFS in action.

Wireless mesh network question

by Andy Stewart

HI guys, I am planning to setup a wireless mesh network at a ham radio event in June. Each mesh node will consist of two Linksys WRT54GLs, much like the demo I showed at a recent WLUG meeting. One of the WRT54GLs will be on channel 6 and carry mesh network traffic. The other one will be on channel 1 and allow generic wifi devices access to the mesh network. It seems like there would be an interference problem if every node allowed wifi access on channel 1. Should this be 4 different wifi channels? It is possible for a user to be within radio range of multiple of them simultaneously. Thoughts? I've never setup a wireless network before and could use your advice. These mesh nodes will be placed outside in weatherproof enclosures with battery power. Thanks!

STM8 blue pill boards and programmer

by John Stoffel

Guys, I've got some STM8 bluepill boards and a spare knock off ST-Linkv2 programmer if anyone is interested. I was playing around with them this weekend and the lack of a decent IR Library meant that my interest has waned. They're cheap cheap chear, and interesting as a way to learn more low level programming. I can give you my linux notes if you like too! Or if you know of a library for STM8 that does both send/receive of IR codes, I'd love to hear about it. I'd trade for an AVR ISP programmer instead if anyone has one, since I'm now more interested in ATtiny 85/84/88/841 boards these days. I won't be able to make meetings (unless maybe if you have one the 16th of this January) for a while though, so we'd have to arrange a meetup or something. Cheers! John

Re: DECStation 3100 on a RPi2040...

by Jon "maddog" Hall

The DECstation 3100 (aka the PMAX) was a system based on the same motherboard as the VAXstation 3100, except with a MIPS processor. It was the first time that Digital had built a system using another company's chip architecture. We had a choice between supporting the MIPS R2000 chip as "big endian" or "little endian". We chose to support "little endian" to be compatible with PDP-11s, VAXen and Intel chips, rather than be compatible with other manufacturers. This, in my mind, was very important since it let us share data over NFS and give greater compatibility with programs and libraries of applications already running on other Unix-like systems such as Ultrix, BSD, etc. Sun experienced this grief when they ported Solaris off the big endian Motorola and SPARC chips to little endian Intel. One of the few issues of the DECstation 3100 (and 2100, known as the "PMIN" after that) was that the serial I/O port did not support hardware handshaking. To save a couple of pennies per system the VAX hardware designers determined that having full hardware modem control (DECstandard 52) on the board was not needed, because "very few workstation users hook a modem up to their serial line". What they meant was that "very few VMS workstation users hooked a modem up to their serial line", opting for DECnet to handle their networking. Therefore the pins necessary to support hardware modem control were missing from the DECstation product lines. Unix users, on the other hand, often had modems hooked up to their workstation, to handle cu(1), uucp(1) and other serial line protocols. We eventually got around this by better refining software modem control, but it was painful. The proposal, design and release of the DECstation 3100 was a top-secret project inside of DEC, kept secret from even many people in the Digital Unix group in Nashua, New Hampshire. The development of the system was done in Palo Alto's WorkStation Engineering group and the software engineering was done in the Western Software Labs in Palo Alto, albeit by taking key engineers from the Nashua facility and transplanting them temporarily to Palo Alto. The implementation was kept so secret that it caught Dave Cutler, then working on DEC's next-generation operating system and chips, by surprise when it debuted at a Board Meeting in Maynard, Massachusetts. Shortly after that board meeting Mr. Cutler left Digital and moved (with some of his team) to Microsoft. The DECstations only were manufactured for a couple of years, as the DEC Alpha processor replaced MIPS in Digital's lineup. Although originally promised that OSF/1 would be ported to the DECstation line, this port was dropped due to realizing that there would never be an application base to support the customers of a DECstation OSF/1 port. It was better for ISVs and customers to maintain the Ultrix base for the DECstations than to split the base into Ultrix and OSF/1. md On Fri, Jul 5, 2024 at 9:02 AM John Stoffel via WLUG <wlug(a)lists.wlug.org> wrote: > > My first real Unix workstation, reduced. > > https://github.com/rscott2049/DECstation2040 > > This brings back memories.
