Kermit is the name of a file-transfer and -management protocol and a suite of computer programs for many types of computers that implements that protocol as well as other communication functions ranging from terminal emulation to automation of communications tasks through a high-level cross-platform scripting language. The software is transport-independent, operating over TCP/IP connections in traditional clear-text mode or secured by SSH, SSL/TLS, or Kerberos IV or V, as well as over serial-port connections, modems, and other communication methods (X.25, DECnet, various LAN protocols such as NETBIOS and LAT, parallel ports, etc, on particular platforms).

We’re an amateur phone collective in Philadelphia! Are you a hacker, artist, or engineer? We need your help!

PhilTel is looking to install new (to us) payphones within the city of Philadelphia. Any payphone installed will be completely free-to-use, allowing the user to place calls within North America. Additionally, we would like to provide various experiences and services through the phones; these could be as simple as voicemail, fun as a phone number that randomly calls other payphones, or as complex as an integration with phone collectors’ networks to allow phone-phreaking and exploration!

University of Oregon Route Views Project

The University's Route Views project was originally conceived as a tool for Internet operators to obtain real-time BGP information about the global routing system from the perspectives of several different backbones and locations around the Internet. Although other tools handle related tasks, such as the various Looking Glass Collections (see e.g. TRACEROUTE.ORG), they typically either provide only a constrained view of the routing system (e.g., either a single provider, or the route server) or they do not provide real-time access to routing data.

While the Route Views project was originally motivated by interest on the part of operators in determining how the global routing system viewed their prefixes and/or AS space, there have been many other interesting uses of this Route Views data. For example, NLANR has used Route Views data for AS path visualization and to study IPv4 address space utilization (archive). Others have used Route Views data to map IP addresses to origin AS for various topological studies. CAIDA has used it in conjunction with the NetGeo database in generating geographic locations for hosts, functionality that both CoralReef and the Skitter project support.

Open Infrastructure Map is a view of the world's infrastructure mapped in the OpenStreetMap database. This data isn't exposed on the default OSM map, so I built Open Infrastructure Map to visualise it. If you want to edit the data and you're new to OpenStreetMap, check out learnOSM.
If you already have some OSM experience and want to start tagging infrastructure things, take a look at the tagging guidelines for power and telecoms.

The Telephone Central Office Building Pictures website was created for one reason only - historical preservation.

The telephone central office is the location where local landline telephone switching takes place. Inside is a specialized electronic telephone "switch" where phone calls are transferred from one customer to another, or to another central office via a long distance circuit.

The central office is almost as old as the telephone itself. Often times these buildings were built many years ago with an architecture that has been long ago forgotten. Many times these buildings were very large to accommodate the analog switching equipment of the day - Step by Step, Crossbar, Panel or early electronic. These days almost all central offices have modernized their switching equipment to a fully electronic system that takes up only a tiny space where years ago large electro-mechanical systems took up floors of space.

As telephony has changed over time, many people are now abandoning the traditional landline telephone for cellular or various Voice over IP methods. The theory is that as traditional landline use goes down, these buildings of yesteryear may disappear.

The goal of this website is to preserve these buildings for future generations in the years ahead. About 50 years ago, a telephone preservationist called "Mark Bernay" started recording telephone sounds. He now has a website called Phone Trips. Also on that website are sounds from his friend "Evan Doorbell" from 45 years ago. All the switching equipment that made these sounds are long gone. With the help of these two folks and others like them, we are able to listen to these sounds today. This site has as similar goal - preserving what we have now for people to look at in the future.

Public copy of the telecom-archives mailing list.

Telecom Digest was started in August, 1981 by Jon Solomon as a mailing list on the old ARPA network. It was an offshoot of the Human Nets forum intended for discussion of telephones and related communications topics.

Pat Townson moderated the Digest from 1996 until he suffered a stroke in 2007, and Bill Horne has been the Moderator/Editor/facilitator of the Digest since then. The moderator works through accounts provided by the Massachusetts Institute of Technology in Cambridge, MA.

Telecom Digest is not strictly speaking part of Usenet. It is an official Internet mailing list publication. A decision was made at some point in the past to 'port' the Digest to the Usenet news group 'comp.dcom.telecom', in order that Usenet readers would be able to participate in the Digest. I became Moderator of comp.dcom.telecom in 2007 in addition to being Moderator of Telecom Digest. For all practical purposes, the messages in comp.dcom.telecom are identical to the messages which appear simultaneously in The Telecom Digest, although readers of The Telecom Digest have the option or receiving an actual digest, i.e., they can sign up to receive all of the posts for a single day combined in a single email.

The Telecom Digest is the oldest continuously published mailing list on the Internet.

At Futel, we believe in the preservation of public telephone hardware as a means of providing access to the agora for everybody, and toward that goal we are privileged to provide free telephone calls, voicemail, and telephone-mediated services. We do not judge the motivations of our users, or who they choose to call; if they don’t have someone to call, we can provide a presence on the other end. Denial of telephony services has long been a tactic used against undesirable populations, and our devices will counteract that. But more importantly, we will help to establish a new era of communication, one in which reaching out is not only desirable, but mandatory.
