| 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: |

| to input. # = number, not pound, <sp> = spacebar.) |
|
|
| Example: If I wanted to set the system's date to 1/4/1943 (heh) |
| then after logging in I would press, "c" then "d", then |
| "43", then "1" and finally "4". |

|
|
|
|
| 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. |
