Telephony Home Lab Part 2 – Mistakes Were Made

SO…buying any kind of old computer gear or technology can either be considered buying collectibles, or throwing money into a fire pit. In other ways its all about the experience; nobody is buying a $4k Altair to run Crysis; they’re buying $4k video cards. Since I’m not sure how collectible an old PBX will ever be, I’m considering it the latter, so the idea is to minimize the amount of spend as much as possible. That said, sometimes it makes sense to look at the big picture and try to find something that best fits your needs wants, instead of trying to find “the cheapest stuff possible”.

Why a Merlin PBX? In Part 1 I mentioned that I saw a ton of Merlin stuff get scrapped back in my childhood days, and the 1980s retro-futuristic (or perhaps space-age) look of the hardware has me on a nostalgic kick. In addition, after reading up on the Merlin stuff, I find it has some relatively interesting features, including the ability to “live behind another PBX” (like Asterisk), and handles a venerable plethora of connectivity, including POTS, T1/PRI, IDSN (including BRI!), and supports several generations of phones from the old space-age devices to 90s-rific Avaya 44xx series phones. So long story short, I wanted one for both nostalgic reasons, as well as even a few practical-ish ones. There are MANY MANY other PBXes, some of which may even fit all my actual needs (see my notes below regarding ISDN), but for now I just wanted a Merlin.

Read on to find out what I ran into buying/building an old PBX. These nuggets can be applied to other things in life as well, and I’m humble enough to admit my fumbles. Buckle-in as this is a multi-part…part.

The Devil is in the Details – Research EVERYTHING.

Telephony equipment varies a LOT when it comes to standards, and even devices that LOOK similar, from a similar era and even the same company, may not be compatible. For example, At&t made a variety of those space-age-looking phones, that while looking identical, some were not compatible with the Merlin systems; they were for the Definity family.

Telephony Home Lab Part 1.1 – Use cases and Justification

Before I get into the mistakes made part, let me take a moment to talk about the telephony home lab, what my thoughts/ideas were behind it, and why I chose to include a vintage PBX into the mix (short answer – because I felt like it).

In some cases, IT people like myself often run “home labs” (or homelabs if you prefer), basically small (sometimes not so small) IT setups in their home, partially just to tinker and have fun, partially to learn or TRY things , and sometimes providing useful services to the household in the process.

Telephony Home Lab – Part 1 (featuring the At&t Merlin Phone System)

Well, after December 2020 was quite a doozy of a month, December 2021 said “hold my beer” and blew away whatever crappy stuff was happening in 2020, to the point where for the first time in my life (since I can remember), I actually did not celebrate Christmas with my family. More on that later, but long story short despite having more projects than I know what to do with, my ADD brain led me to hyperfocus on telephony; something that I hold dear to me as exposure to most of ma bell’s refuse (equipment, phones, switches, computers, etc) in my childhood is what led me to technology in the first place. I had access to a ton of gear (even just seeing some of it) through a family friend that owned a recycling plant near my uncle’s house, and got to bring home some stuff like old phones (2500 sets) and tinker with them.

Early Merlin 5-button phone

One thing I distinctly remember were many “Merlin” phones; and of course getting a nostalgia kick, I found a couple “analog” Merlin phones that had that silver/sleek 1980s futuristic look I remember, with membrane buttons and the At&t logo.

R. R. (Dick) Farr – Political Calling Card

I recently got to raid the attic of my cousins’ former historic house in Virginia, as they’ve moved to a new place. In the attic though was tons of ephemera from the former owners of their house. I grabbed a handful of things, although in hindsight I wish I grabbed more.

In the collection was a shoe box of letters and ephemera from Mr. and Mrs. Richard (Dick) Farr, a former politician and lawyer in Fairfax County, VA. Mr. Farr was really Richard Ratcliff (Dick)Farr III, succeeding his father Richard Farr II, who had a storied life in both politics and the confederate war. (His father’s story can be found in various places, such as here and here, and is worth a read.)

Home Network – Death by 10,000 Cuts

I’ll be honest, despite being in IT, my home network never really worked “great”. I mean it did, sometimes, maybe, but not always. To complicate things, my house is by-level, and has enough weird geometry to make an engineer have a migraine. I’ve fiddled with my home network MANY times over the last 10 years I’ve been here, and thought I’d do a write up on various things I’ve tried, including various technologies I’ve tried and their pros and cons.

Also to note – things generally worked…if they were that bad I’d have done more sooner, and I also wanted to learn WHY I was having issues, not just throw money at the problem. I also admit my mistakes; I’ve learned so much from people on the internets being humble and admitting if they made a blunder here and there, so I’ll admit my blunder wasn’t just focusing on this sooner than later.

Buckle up – this is probably my longest post yet, but I kept some pages short.
See the last page for TLDR/summary.

First Generation

The first setup, was a typical Comcast (Coax) cable internet feeding an Asus N66U router in my basement. Keep in mind, my basement is sorta ground level, due to my house being partially built INTO a hill. My house is also fairly small, and really a single router should be able to easily provide for the entire house if not the entire property, or so I thought.

Eventually I came to find the wifi never really worked well, and my workbench computer in the garage, which is a separate building, would struggle to connect. I realized early on that being “too low” was likely causing my WIFI issues.

Second Generation

So in order to get better internet up to my office which is in a bedroom, and out to the garage, I learned about Powerline Ethernet adapters, and thought “HEY these should be perfect!”. I bought a kit or two (made by Netgear), and honestly, they did generally work “OK”. Speed test showed modest connectivity and they were fairly reliable, both in the house and out to the garage.

…until I wanted to play radio. I have a “General” amateur radio license, which allows me access to “HF” frequencies. The first time I started listening in on HF, I had a constant noise all over the bands. I could tell it was artificial, and eventually I realized when looking up a call sign, the noise changed based on my internet access, so I immediately suspected the Powerline adapters. I unplugged them all (all 3 or 4), and immediately it was confirmed, I lost a TON of noise. While I could have kept them, I decided I didn’t want to use them anymore if they were that “RF noisy”, which led me to my third-generation setup.

Third Generation

So I realized I needed to get back to using WIFI better, and it had to get out of the basement, but I was too lazy (or too nervous) to drill holes in walls and run a network cable or coax down to he basement (don’t ask me why, I’ve done it a bunch of times). So at some point I found a second Asus N66U router, identical to my existing one, so I figured “GREAT”, I’ll run a repeater.

So I set up a second Asus router in the office bedroom which acted as both a repeater and bridge. Generally I’d use the repeated network for most things, and it actually worked fairly well. I knew it was a compromise setup so I wasn’t too worried about speed or bandwdith, as long as I could stream some movies and work I was generally good. Or so I thought. Again.

Fourth Generation

Queue the pandemic. Whereas before most of my internet and network use was in the evenings after work, now I needed it FOR work. Then I got bit by the home automation bug, and I needed it for lights. Then I bought Sonos speakers, and I needed it for audio, so my formerly “basic internet access” network became a lot more complicated, and a lot more necessary. As I added more and more things to the mix, the repeated network started breaking down, where things were delayed, access to the garage was hit or miss, the Sonos speakers cut out and acted up, but somehow, working every day was actually fine. VPN fine. So I just thought well maybe I just have too many things on WIFI at this point.

Conference Travel – Life Hacks Part 2

Hard to believe so much has changed since 2019; I originally started this as a 2-part post on conference travel, and unfortunately since December 2019 when I wrote this, I have not attended one conference since in person. Here's to hoping things will continue to get better. That said, once they do, here's my "Part 2".

Continuing on with the tips…

Have Fun – But Don’t Overdo It!

Make sure to have fun as well; true you’re there for work, but you’ll work better if you balance the fun with the work.

Links Page Updated – and cool site to share (Vladstudio)

Go figure, I pull the links page down since it was empty anyway, only to randomly start filling it in, then putting it up again. I wish I knew why my brain works like that sometimes, but I’ll take what I can get LOL.

Anyway, I figured I’d mention a special link – Vlad Studio – https://vlad.studio/

If you’re looking for some interesting and unique wallpapers for your computer, look no further than Vladstudio. I’ve actually had this bookmarked for probably the better part of a decade, maybe 2, not sure, but honestly haven’t checked it out in some time. While he does charge (minimally) for access to his premium content, the price is very reasonable and worth every penny. I bought an access code some time ago, and will definitely be downloading some new wallpapers to use – as someone who tinkers, the Woodworking one is particularly appealing, even though I’m pretty terrible at actual woodworking.

Enjoy!
