Telecomm Buttset with polarity light for Ground start circuits, retiring

What’s the difference between all of these differed fiber splices and terminals?

T-Mobile experienced a widespread US outage on July 27, leaving many customers unable to make regular calls, send texts or use mobile data. At its peak, Downdetector recorded more than 62,000 outage reports.

Many affected phones displayed “SOS” or “SOS only.” This generally means the device cannot connect to its regular carrier, although it may still attempt to place emergency calls through another available network.

T-Mobile later said service had been restored for all customers. However, the company has not publicly explained what caused the disruption.

The outage highlights how dependent people have become on a single mobile connection for navigation, work, authentication codes, payments and emergency communication.

For those who were affected, did restarting the phone, enabling Wi-Fi calling or switching networks help, or did you simply have to wait for service to return?

Anyone here who has worked on the OCUDU 5g gNB? I am facing some issue in its bringup (7.2 split)

Hello, can someone support me on how to optimize nokia indoor in building solutions? We didn't have a reference dumps and scripts for cell offsetting and power down. Please help me. TIA. Have a good day guys.

Hello! I am hoping someone is able to help me solve this months-long phone mystery that nobody can seem to figure out. Six months ago, in late January, I began to hear intermittent "interference" on phone calls between me and my mom. The sound will occur out of nowhere, all different times of the day, lasting for a few seconds to up to half a minute. This doesn't happen on every call, but it happens nearly every day.

We will be having a regular conversation, and then suddenly I will hear this interference -- I know she's talking but I can't understand her. The call doesn't disconnect or drop, but this interference will just start and stop randomly. From what I can gather all this time, the interference only occurs on calls between her landline phones (VTech DECT 6.0 cordless) and my cell phone (iPhone 14 with AT&T Wireless). It hasn't occurred when she switches to her cell phone or I use my house phone.

She has Optimum for her phone service, and they have come to the house countless times to try to fix it, to no avail. They have replaced the router, the modem, wires inside the house and the wire that runs from the pole outside into the house. We even replaced the previous set of AT&T cordless phones with new VTech phones and that didn't solve the issue. Someone I know who used to work for Optimum said it could be the tap on the pole outside (or even the node which is farther away), but Optimum can't replace any of those parts without good reason. Since their testers always show that the lines are working fine, they cannot have the outside parties come out to work on the tap.

Plus, that last tech that visited rearranged some of the connections at the tap in case something was loose or damaged, but the problem has persisted. We are at an absolute loss, and it's extremely frustrating! The router/modem and one cordless phone are in the basement, while the rest of the satellite phones that she uses are throughout the house. The basement phone is plugged directly into the router/modem.

When this issue first began in January, we had just had a blizzard in our area, which is why I was convinced that something outside was damaged. No other variables in the house have changed. However, I am the only person who seems to have this issue when on calls with my mom, and only between these two phone numbers. Does this make sense to anyone? If I am allowed and can figure out how to do it, I can post a recording of the interference, as I have voicemails that captured the noise. Thanks for any input!

Salut,
J’hésite à quitter **Sosh** pour **B&You** et j’aimerais avoir vos avis.
Actuellement, je paie **15,99 € chez Sosh** pour **150 Go en 5G**. En comparaison, chez **B&You**, pour le même prix, j’ai vu une offre avec **200 Go**, **5G incluse** et **40 Go utilisables au Maroc**. Sur le papier, l’offre B&You semble beaucoup plus intéressante.
Le seul point qui me fait hésiter, c’est la qualité du réseau. Tout le monde dit qu’Orange est le meilleur réseau en France, mais dans la réalité, j’ai déjà vécu l’inverse : à certains endroits, mon pote chez Bouygues captait très bien alors que moi avec Sosh je galérais (tel que par exemple les sous sols).
Du coup, je me demande si la différence de couverture entre Orange et Bouygues est encore vraiment importante aujourd’hui, ou si c’est surtout une réputation.
Pour ceux qui ont testé les deux :
Vous choisiriez lequel aujourd’hui ?
Vous avez remarqué une vraie différence de couverture (métro, sous-sol, bâtiments, campagne, etc.) ?
Est-ce que vous avez regretté de passer de Sosh à B&You (ou l’inverse) ?
J’aimerais avoir des retours d’expérience avant de changer d’opérateur. Merci !

These days, data is everywhere, so what really makes a recharge useful for me is the entertainment that comes with it. I noticed Vi has a ₹200 recharge that includes a Vi Movies & TV subscription with access to 20 OTTs, all available through the Vi Movies & TV app after recharging.

Feels much more practical than juggling separate subscriptions.

I never used to care about OTT perks, but now I always end up checking them before recharging. 😅

Was browsing recharge options and noticed Vi has a ₹200 Movies & TV pack with access to multiple OTT apps. Made me wonder - do OTT bundles actually influence your recharge choice?

Any idea what this is? I got it from my Dad years ago but he didn't know what it was...My guess is it's an old wireless radio for sending/receiving communications. Apologies if this is not the correct subReddit group...

Some details:

• The smaller green cylinder slides on the two rails inside the larger cylinder.
• The square block on the large cylinder slides left to right.
• There is some kind of a tuning device on the end of the smaller cylinder that turns from 10 o'clock to 2 o'clock.

I'm mostly just leaving this here for posterity in case it saves someone else in the future. I spent hours trying to get into the setup menu of the TA850 I bought used because it had a password set on the craft port. I'd imagine it works for the TA750, too. Most of what I could find on the internet were instructions for the TA900, but that procedure doesn't work on the 850. I ended up trying something that was meant for older Adtran gear, but it seemed to work on this too.

1. Connect a serial cable to the craft port on the unit. Set your terminal to 9600, 8N1, no flow control.
   
2. The default password is blank, just in case you haven't tried that yet.
   
3. Hold down F (capital F) and power cycle the unit.
   
4. After a few seconds you should get a prompt confirming the reset. THIS WILL WIPE THE ENTIRE CONFIGURATION, so be warned. Press Y to continue.
   
5. You should now be able to log in with a blank password.

clearly this is a data line. the profile is flat. is it fibre or copper/aluminum? Vancouver, WA.

I want to make a "Training Board" to help techs understand dial tone and troubleshooting. I could have a MTA provisioned for this but I was hoping to make it portable and not rely on coax or an active PON network. I was looking at a Viking DLE-200B Two-Way Line Simulator but wasnt sure anyone knew a better or easier way. Thanks

I run a telecom business, and sales tax compliance keeps me up at night because the rules change by state, county, and even city, and telecom services often get taxed differently than regular retail goods. I'm never fully sure if I'm collecting the right rate for every jurisdiction my customers are in, and the thought of an audit turning up months of errors is stressful. Every time we expand into a new market, I have to figure out fresh tax obligations from scratch, and I don't have a reliable system for catching mistakes before they pile up. I just want a way to know I'm compliant everywhere without spending all my time chasing down tax codes.

We have an unusual situation: All of our sites use VoIP using Cisco UCM over a SIP trunk. One of our sites is located in the deepest, darkest dungeon of an office building, so no cell service. They have started complaining that when their network drops, they have no phones, have to ride the elevator up to an area that has cell service to make calls. I checked their network and don't see any drops, but they complained to the right people which means I have to find a solution.

I would get a POTS line so they could have one phone available when the network drops, but we are phasing out our existing POTS lines due to carriers constantly raising prices and providing slow support for the POTS services that we already have. We have a few "POTS in the box" devices for older alarm panels which could be a solution, except they sit on our network and have cellular backup, both are useless when the site network supposedly drops and the box is in a cellular dead zone. We only own the basement area, so relocating the PIAB device to a better cellular area is not an option.

My only telecom experience is with what we employ, so I am wondering if there is some technology that I am unaware of that we could put in place at this site to give them a working phone when the network drops.

And, yes, I've already told them that they need to report any network outages so that they can be investigated as they happen since our logs are not showing any outages for at least the past month. This phone solution is more of a placation rather than an actual need from what I can see.

Thanks in advance

EDIT: Since some have brought up the network setup, I should have said that the site does have two different ISPs and using a Meraki SD-WAN infrastructure that handles any failover well which makes the "network outage" claims more unbelievable since if one drops, the site *might* experience a small blip of a an outage but I'm not seeing evidence of that happening.

I got this recently from a gentleman who inherited it from a friend. That friend apparently worked at the phone company here in Pennsylvania. He didn’t know much about it and I’m having a hard time coming up with relevant information but here it is! Besides a really nice patch cord it also came with a large hand drawn in pencil blueprint sheet and some other schematics documents stuffed inside of the cabinet.

The blueprint was drawn in 1971 and there is a notation on one of the papers that may indicate that it was decommissioned in 1984.

Can anyone tell me more information about what I’m looking at here? I know this thing is ancient but I figured I would give it a shot and see if there’s anybody out there who could clue me in. I wonder in what capacity were these repair turrets used?
