| FMT-150B/C/D | |
| Optical Fiber Digital Transmission System | |
| Intro | |
| This file will cover the FMT-150, the equipment that sends info over | |
| the digital trunks using lasers. It is an accompaniment to our guide | |
| to remotes (COs). I will cover all the interesting and useful stuff. | |
| This file is mostly for SERIOUS phreaks, we'll have more non-technical | |
| cool stuff coming up. | |
| System Description | |
| The FMT-150 fiber optic transmission system combines DM-13 | |
| multiplexers and 150 Mb/s Fiber Transports in compact shelf | |
| packages, I will refer to it as a shelf. The FMT-150 product | |
| architecture supports subscriber loop and interoffice link | |
| applications using hub, drop/insert, repeater and terminal | |
| configurations. The following is what a FMT-150 shelf system | |
| consists of. | |
| FMT-150B 1 DM-13 multiplexer (multiplexes 3 signals | |
| into one signal of 44.736 Mb/s.) | |
| 1 150 Mb/s fiber interface | |
| 1 maintenance control unit | |
| 1 service channel unit (optional) | |
| 2 (or 4) power supply units | |
| FMT-150C 2 DM-13 multiplexers | |
| 2 (or 4) power supply units | |
| FMT-150D 2 150 Mb/s fiber interfaces | |
| 2 service channel units (both optional) | |
| 2 maintenance control units | |
| 2 (or 4) power supply units | |
| Maintenance | |
| Service Channel Unit | |
| Order-wire Facility | |
| Two voice channels per DS-3 signal are provided for individual | |
| addressing using DIP switches on the SCU. Dial over a 4 wire | |
| headset/handset. (more in Order-Wire) | |
| Interfaces | |
| The CRT (good old Cathode Ray Tube) Interface is an important | |
| system feature of the Maintenance Control Unit (MCU). You can | |
| plug in to a RS-232 port directly (use a null-modem cable) on the | |
| "shelf" or remotely via a modem (!). Also a Tandy 200 can be | |
| interfaced with the Maintenance Control Unit. The network | |
| configuration, the status of each node, and any alarm existing | |
| can be viewed on the terminal. The interface goes from 300 to | |
| 9600 baud. The software already present on the MCU is all that | |
| is needed, the interface need only support certain emulations | |
| (see Operation Procedures.) (hmmm... Could Radio Shack and | |
| Northern Telecom be butt buddies?) Also available is a | |
| RS-422 interface which provides a large number of alarm status | |
| and control points through the MCU. The port is labeled | |
| "Customer E2A" on the shelf. CAMMS is an extended feature | |
| of the FMT-150. It stands for Central Access Maintenance and | |
| Monitoring System which can also take advantage of the | |
| Maintenance features (see Operation Procedures). All this is, | |
| is a mini-terminal, that can be installed and act like a CRT | |
| interface. | |
| Specifications | |
| When interfacing the CRT with a null modem cable, your cable | |
| should fit the diagram below. | |

| Alarms and Buttons | |
| Listed below are some LED descriptions and button meanings that a | |
| phreak will find on the shelf. | |
| LEDs Description | |
| ----------------------------------------------------------------- | |
| MAJOR RED - Service affecting failure | |
| (run, they'll be there soon!) | |
| MINOR YELLOW - Non-service affecting | |
| failure. | |
| FUSE ALARM RED - A fuse blew | |
| REM YELLOW - An alarm has occurred at | |
| a remote site. | |
| Order-wire Left GREEN - Solid, Left order wire is | |
| active, if flashing, incoming | |
| call on left. | |
| Order-wire Right Same as above, but for Right | |
| ----------------------------------------------------------------- | |
| BUTTONS Description | |
| _________________________________________________________________ | |
| LP TEST Lights up all LEDs | |
| ACO Turns off existing audible alarm | |
| LOC 1, 2, 3 (OW) Rings every site common to STX | |
| signal 1, 2, and 3 | |
| EXP 1, 2, 3 (OW) Same as above | |
| ----------------------------------------------------------------- | |
| Power Supply Unit | |
| This is a seemingly 5V output power supply, which has a simple | |
| ON/OFF switch which is housed under a protective latch, pull this | |
| and have an instant phreak marathon (see REDUNDANCY at end of | |
| file.) | |
| Equipment Configuration | |
| The FMT-150 system is suitable for a wide variety of | |
| applications, as follows: | |
| * Access Networks | |
| CO to Customer Serving Areas | |
| CO to Digital Loop Carrier | |
| CO to Switch Remote | |
| CO to Customer Premises. | |
| * Inter-Office Trunk routes | |
| * Broadband Applications such as Video | |
| * Entrance Links to Radio Systems | |
| * Dynamic Network Routing | |
| * Stand-Alone Multiplexer Applications with Radio | |
| * Route Diversity | |
| * Wide Area Network (WAN) Application | |
| Order-Wire | |
| Order Wire | |
| A buzzer is heard and a flashing LED is seen if a call is | |
| coming in, plug in a handset/headset connector into the jack on | |
| the shelf. To terminate the call pull the plug out or hit #. To | |
| dial, just plug in and dial four digits, wildcards are also | |
| allowed by use of the * key. The handset described is a | |
| Contempra Handset (NT2E36AA). A test set could also be used but | |
| the plug would have to be altered, its 4 wire, remember. Order Wire | |
| is only CO-to-CO communication. The jack can be plugged into the | |
| front of the FMT-150 shelf. The dialing format is described below. | |
| ----------------------------------------------------------------- | |
| First digit: Indicates the type of call being made | |
| Second, Third, and Indicated which site will be dialed. | |
| Fourth digits Address of the site is set via rotary | |
| switches located on the front edge of | |
| the SCU module. | |
| ----------------------------------------------------------------- | |
| First digit significance | |
| 1 = local call for STX ({Pseudo} Synchronous Transport Signal: | |
| First Level at 49.92 Mb/s [NT]) signal 2 | |
| 2 = local call for STX signal 2 | |
| 3 = local call for STX signal 3 | |
| (where'd 4 go?) | |
| 5 = express call for STX signal 1 | |
| 6 = express call for STX signal 2 | |
| 7 = express call for STX signal 3 | |
| The three following digits are not standard, so if you want to | |
| experiment with this hit a first digit and then three *'s | |
| On the shelf there are buttons which act like speed dialing, the | |
| first three letters stand for LOCal or EXPress and the number is | |
| the signal, so EXP 2 would be broadcast call on STX signal 2, | |
| express channel. | |

| Login Procedures | |
| If you approach the FMT-150 shelf and have a previously described | |
| interface, then you can login. Also if you are scanning (GTE | |
| (Northern Telecom) areas only) and come across a "sitting system" | |
| that displays a message (below) after hitting 3 returns, you are in! | |
| 1 - DEC VT100 | |
| 2 - NT Meridian 6000 | |
| (Crosstalks or Procom with VT100 | |
| emulation) | |
| 3 - Tandy 200 (running Telecom) | |
| F4- NTCAMMS MDU | |
| Enter Terminal Type: | |
| Choose your terminal type, usually 2 (use VT100) if you are calling in, | |
| and it will prompt you with a "Login: " prompt, this is a trick, there | |
| are no user levels, the "Login:" simply means enter the password, and | |
| the default is to hit return, so always try that first. If a password | |
| is installed then try something like FMT-150 or something that you would | |
| think they would use. You should get a screen like this one after | |
| choosing the terminal type: | |

| NOTE: After executing a local or global MCU reset, the message | |
| "PROCESSOR CRASH" will appear on the bottom of the CRT's screen. | |
| As a result, the user will have to log back into the system. In | |
| addition, a global MCU reset will clear all "names" and | |
| "settings" previously defined (that is, system ID, node, customer | |
| inputs/outputs, time and date). | |
| ----------------------------------------------------------------- | |
| Many other commands are listed but they are extremely numerous | |
| and useless to the average phreak. | |
| If a "terminal" that is 4.4 inches tall with a center screen and | |
| 2 12 key keypads on either side is seen on the shelf, this will | |
| be a CAMMS terminal, all functions above can be performed with | |
| this unit, its menu driven. | |
| Troubleshooting | |
| This section is the manual is devoted to fixing problems in the | |
| FMT-150, aimed at the average see-my-crack-of-the-ass telco | |
| maintenance man. | |
| Basically, if you see any red LEDs, inspect them and judge if you | |
| should get the hell out of the CO or not, usually red LEDs mean | |
| trouble. | |
| REDUNDANCY | |
| When doing anything of this nature to a fone company, you must | |
| remember, they are not stupid, everything has something to | |
| fall back on, if you were to cut a trunk line, there would be | |
| another to take its place. Usually there will be only one | |
| backup, so be meticulous and find both. | |
| Outro | |
| Hope this file was worth something to somebody, it applies mostly | |
| to those in a GTE area, since GTE uses Northern Telecom equipment | |
| and most everyone else uses AT&T stuff. | |
