.oO Phrack 49 Oo. Volume Seven, Issue Forty-Nine 13 of 16 .-----------------------------------------. | Telephone Company Customer Applications | |-----------------------------------------| | Voyager[TNO] | `-----------------------------------------' Telco's use many types of software. In addition to the run-of-the-mill employee applications such as OfficeVisions, PROFS, and the usual trashy selection of DOS/Win applications, telco's use two types of much more interesting software: . Customer applications . Provisioning applications Customer applications are used by telco personnel to deal with customer issues, such as billing and service orders. Provisioning applications are used to deal with the actual phone network itself. Customer applications include BOSS, CARS, CORD, SOLAR, SOPAD, OSCAR, and PREMIS. Provisioning applications include FACS, March, April, COSMOS, Switch and FOMS/FUSA. Most of what has been written regarding telco software covered provisioning applications. While much can be done with provisioning applications, you will soon see the incredible opportunities offered by Customer Applications. Within the family of Customer Applications you will find the ability to locate personal information, look up addresses by telephone number, and modify customer bills. Experienced dumpster divers will recognize many of the screens shown in this article. .------------------------------. | Part I: Billing Applications | `------------------------------' BOSS ~~~~ BOSS (Billing and Order Support System) contains bill and credit information, equipment information, carrier billing information, customer contact notes and payment history. BOSS is used in the Central and Eastern Territories of U.S. West. To login to BOSS, you must enter your a ID, a two character alphanumeric office code, and a five character password. BOSS passwords expire after 30 days and cannot be re-used. BOSS is operated largely with PF keys: PF1 = ENTRY (Entry Screen) PF2 = BILL (Entity and Summary Bill) PF3 = IC (Itemized Calls) PF4 = OCC (Other Charges and Credits) PF5 = CSR (Customer Service Record) PF6 = PREV (Previous Months Bill) PF7 = NEXT (Next) PF8 = Note (Notations) PF9 = ASUM (Adjustments Summary) PF10 = COMPUTE (Compute) PF11 = F/B (Forward/Back) PF2 will bring up the Billing Screen, which will show you the contact names and telephone numbers for the account you are looking at. The CSBL screen is completely covered with information, and it is impossible to get everything out of it without careful study. There are at least two versions of BOSS in use, this screen is a mix of the two that I am familiar with: +-----------------------------------------------------------------------------+ |CMD MSG COMMAND COMPLETED (I210) | |(a)303 265 8545 (b)153 (c)NP (d)JAN 16 93 *CSBL (e)LIVE (f)DNV (g)1FR | |(h)DARIN STOREY (i)PB 0205 (m)RT (q)AC D-00 (t)DEP 0 CN (x)BD N | |515-D GIRARD BLVD S E (j)R1 0126 (n)ES (r)CT (u)DOI 030492 (y)LCU | |BOULDER CO 80301 (k)R2 0216 (o)NT C A (s)NOB (v)TAX FSLCF- (z)LCR | | (l)R3 0224 (p)PPD (w)TAR AJ (A)LAL | | (B)CI SEARS SUPVSR 2426767 MS SANDI SM POE NLR | |DAD MICHAEL STOREY 2755595 (C)CBR | | (D)SSN (E)VL (F)TRT HIST 059511111111 (G)CIV 0290 | | (H)RCK HIST 000000000000 (I)PAH | | PREV BL 168.55 CUR BL 116.24 | | PAY & ADJ PREV BILL PAY AND ADJ CURR BILL | | DATE T AMOUNT DATE T AMOUNT | | 1223 01 101.15 | | (J)010 30.42 | | 221 9.03 | | 300 9.39 | | (K)CCG 48.84 | | (L)BAL 67.40 | | (M)TOT 116.24 (N)CUR DUE 116.24 | | (O)RP (P)NOTATION (Q)TYPE (R)PN (S)ACT (T)FU (U)BD | | 0193 (V)+ | +-----------------------------------------------------------------------------+ Legend: (a) Telephone number (b) Customer code (c) Listing Type (See below) (d) Most current bill date (e) Account Status Code (See below) (f) Alpha code for the serving exchange (g) Class of service (See below) (h) Billing name (i) Pay-By-Date, month and day payment is due (j) Previous months denial date (k) Date first collection notice is sent out (l) Date account will be denied and referred to CMC (m) Remove from treatment amount (n) Entity Status (See below) (o) No Treatment Indicator (See below) (p) Preferred Payment Date (q) Account Classification (credit classification) (r) Carryover Treat History (unimplemented) (s) Number of bills the customer receives (t) Total deposit held on the account (u) Date of Installation (v) Tax Code (w) Tax Area Code (x) Bank Draft (y) Local Units Used (unimplemented) (z) Local Usage Units Credited (unimplemented) (A) Local Usage Units Allowed (unimplemented) (B) Credit Information (C) Can Be Reached (D) Social Security Number (E) Central Office is Voice Link capable (F) Treatment History (read right to left) (G) Credit Information Verified (date CI was last verified) (H) Returned Check History (read right to left) (I) Previous Account History (J) Charges by Entity (charges from AT&T, MCI, etc...)

The three digit carrier code is listed, followed by the letters S, C or F. If the NT (No Treatment Indicator) is C, the computer sends out a late notice on the R2 date. If the NT is T, there is a temporary reprieve and the computer will not sent out a late notice this month. If the NT is M or P, late notices are never sent. PF11 from this screen will take you through the entity CSBL's. PF5 will show you the customers Current Service Record. The CSR screen will look something like this: +-----------------------------------------------------------------------------+ |CMD MSG | |(a)303 864 2475 (b)298 NP (c)NOV 10 99 *CSR (d)P 1 2 DNV 1FR | |(e)BARBARA ANDERSON FOR | |XSBN 2-864-2475 | | (f)---LIST | | NP (NP) ANDERSON, DARRYL B | | LA 5425 ROWLAND CT | | (g)---BILL | | BN1 BARBARA ANDERSON FOR | | BN2 DARRYL B ANDERSON | | BA1 5425 ROWLAND CT | | PO 80301 /TAR GQ | | (h)---S&E | | (i)ORIG SERV ESTAB 8-17-78 | |(j) (k) (l) (m) (n) | |20182 1825 NPU /1000 1.31 1.31 | |41481 7001 TTR /1000 1.12 1.12 | |82585 3793 1FR /1000/PICX288 5.60 5.60 | |41481 2140 KH9 /1000 .00 .00 | |22782 5106 WMR /1000/D .56 .56 | |41481 7001 RJ11C /1000/D .00 .00 | | | |RP NOTATION TYPE PN ACT FU BD | | 1299 | +-----------------------------------------------------------------------------+ Legend: (a) Telephone number (b) Customer code (c) Most current bill date (d) Page number (e) Billing name (f) LIST section containing listed name and address (g) BILL section containing billing name and address (h) S&E section containing products and service (i) Date original service was established (j) Date each service was installed (k) Last 4 digits of order number that put service online (l) USOC's representing the products and services on the account (See below) (m) Monthly rate for each USOC (n) Amount billed for USOC total USOC Codes include: ESC Three Way Calling ESF Speed Calling ESL Speed Calling 8 Code ESM Call Forwarding ESX Call Waiting EVB Busy Call Forward EVC Busy Call Forward Extended EVD Delayed Call Forwarding HM1 Intercom Plus HMP Intercom Plus MVCCW Commstar II Call Waiting PF8 allows you to view the notes the telco is keeping on the customer. This is not a free-form notes screen, but is instead very structured. Notes are automatically deleted after two months unless the type code PERM is used. +-----------------------------------------------------------------------------+ |CMD MSG | |303 864 2475 2298 NP 3NOV 10 99 *CSR P 1 2 DNV 1FR | | | |BARBARA ANDERSON FOR | | | |DATE RP NOTATION USR TYPE PN ACT FU | |1209 1988 ESTAB FREE 976 BLOCK 12-9-88 LTR PERM | |0324 BARB SLD CCS DD 3-1 SKJ PSOC | |0213 NONE NBV CHK | |0213 BARB LOST BL ND DUPT SNT ASAP.

CARS stores bill and credit information, equipment information, carrier billing information, customer contact notes and payment history. CARS user id's are six characters and normally begin with a 'B' for business. CARS passwords (lockwords, in U.S. West parlance) are from 4 to either characters and must contain at least one alpha and one numeric character. CARS passwords expire after 30 days. You will also be asked for a Project Code (use 'M'), a Group Code (use 'G') and a Position #. The Position # consists of a pair of two character fields. The first two characters are the office code and the second two characters identify the individual employee. The CARS interface is quite similar to the BOSS interface. The function keys for CARS are: PF1 = LDD (Long Distance Detail) PF2 = CSBL (Current Status Bill) PF3 = BILL (Bill Detail) PF4 = QTFU (Query/Treatment Follow-Up) PF5 = CCSR (Current Customer Service Record) PF6 = PREV (Previous Month's Information) PF7 = PADJ (Payment and Adjustments) PF8 = NOTE (Notations) PF9 = ABIL (Adjustment Bill) PF10 = COMPUTE (Compute) PF11 = F/B (Forward/Back) PF12 = BESS (Billed Entry Status Screen) PF2 will bring up the CSBL (Current Service Bill) screen, which shows you the "can be reached" numbers and names for the account you are looking at. PF5 will bring up the Current Service Record (CSR). A CARS CSR screen resembles a BOSS CSR screen: +-----------------------------------------------------------------------------+ |CMD___________________________________________ Q: | |(a)303 864 2475 (b)2298 72W (c)NOV 10 99 *CCSR* LIVE (d)P00001 COS | |(e)BARBARA ANDERSON FOR SEA 1FB TAX FSL | | (f)---LIST | | NP (NP) ANDERSON, DARRYL B | | LA 5425 ROWLAND CT | | (g)---BILL | | TAR 1700 | | MCN NXWAC | | COS 852-9200S | | BN1 BARBARA ANDERSON FOR | | BN2 DARRYL B ANDERSON | | BA1 5425 ROWLAND CT | | (h)---S&E | | ENT 000 | |(i) (j) (qty) (k) (l) (tax codes) | |02/18/92 05/18/90 1 FB/TN 621-2475/PIC XXX/LPS 42.10 &# | |02/16/90 05/18/90 1 HSO/TN 621-2475/SLS 2.00 &# | | 377000 | |02/16/90 02/16/90 1 TTB/TN 621-2475/SLS 0.00 & | | 377000 | |02/16/90 02/16/90 1 9ZR/TN 621-2475/SLS 4.22 | | 377000 | |RP-___________NOTE_________________________________________________________ | |____________________________TYPE_____FLUP_____PN_____ACT_____BD_____USR_____ | +-----------------------------------------------------------------------------+ Legend: (a) Telephone number (b) Customer code (c) Most current bill date (d) Page number (e) Billing name (f) LIST section containing listed name and address (g) BILL section containing billing name and address (h) S&E section containing products and service (i) Date original service was established (j) Date each service was installed (k) USOC's representing the products and services on the account (l) Monthly rate for each USOC Just as with BOSS, PF8 brings up the NOTE screen.

CORD has three functions: . Accessing service orders by order number . Locating order numbers by telephone number . Locating order numbers by telephone prefix Let's say you know that an attractive young lady is moving into your apartment complex but you don't know her apartment number or her telephone number. Connect to CORD and pull up all of the service orders for the apartment complex's prefix and scan them until you find one in the apartment complex on or near the date she moved in. It's much easier if you have at least a first name. To use CORD, you will need to know the code for your NPA. 206 is 0, 503 is 5 and 509 is 6. SOLAR ~~~~~ SOLAR (Service Order Logistics and Reference) is used in Southern 308, 319, 402, 515, 605 and 712. In addition, SOLAR is used in Northern 218, 507, 612 and 701. I do not know of an NPA where SOLAR is used exclusively. SOLAR has two capabilities: . Accessing service orders by order number . Accessing service orders by telephone number SOPAD ~~~~~ SOPAD (Service Order Provisioning and Distribution) is used in 208, 303 (TNOland), 307, 406, 505, 602, 719 and 801. SOPAD has two capabilities: . Accessing service orders by order number . Accessing service orders by telephone numbers .--------------------------------------. | Part III: Miscellaneous Applications | `--------------------------------------' PREMIS ~~~~~~ PREMIS (Premises Information System) is a geographical database designed by BellCore and used by various telco's across the country. Using Premis, an employee can do customer lookups by telephone number (CNA), check for multiple subscribers at an address (upstairs/downstairs), and view account status. PREMIS can be used directly, but it is also used by applications such as SONAR (Service Order Negotiation and Retrieval). To do successful PREMIS lookups, you will need to be able to encode your requests in the proper format. This is very difficult unless to do this on a regular basis. To make matters more difficult, "proper format" differs from area to area, even within the same RBOC! Particularly difficult are trailer parks, nursing homes, military bases and indian reservations. The PREMIS input screen looks like this: +-----------------------------------------------------------------------------+ |REQ PREM (a) | |SAGA (b) | |ADDR (c) | |LOC APT (d) FLR BLDG | |AHN (e) RT BOX (h) | |COM (f) TN (i) LN (j) STATUS (k) | | | |DAC (g) | +-----------------------------------------------------------------------------+ (a) Screen name (Request PREMIS) (b) Street Address Guide Area (see below) (c) Address (d) Location or apartment (e) Assigned House Number (f) Community (g) Destination Address Code (h) Route and Box (i) Telephone Number (j) Line Number (k) Status Valid SAGA codes include: CHY Northern Wyoming CPR Southern Wyoming DNV Denver, Colorado IDO Idaho MTA Montana NCO Northern Colorado SCO Southern Colorado NMX New Mexico PNX Phoenix TSN Tucson UTA Utah NE Nebraska If the PREMIS database was able to understand your query and find the address information, you will see an output screen that looks like this: +-----------------------------------------------------------------------------+ |REQ PREM TCAT (a) L# 1 BD (b) | |SAGA MN (c) EMP NMX | |ADDR 7821 LYNDALE AV S | |LOC APT 11 FLR BLDG | |AHN RT BOX | |COM***BLMGTN ST MN | | TN LN STATUS | | | |DES (d) | |DESCRIP (e) LYNDALE LODGE | | ZIP 55420 EX(f) MPLS WC(g) 612881 NPA(h) 612 RZ(i) 00 RE(j)| | BO DIR RTZ(k) 2 CO(l) 881 LCL(m) 1ESS | | PC(n) FDT,SAT TELF(o)1ES TAR(p) OTHR PD(q) | | (r)RMK | | | | (s)RMKT SCD: NPS ATX | | | | (t)RMKB LCC IS LCT # (v) (w) (x) (y) | | (u)STAT NON-WORK 06-23-96 TN 612 505-1942 CT Y CNF N DIP N CS 1FR | |LN JORGENSEN,ROBERT C & DIANE MWS NONE | | | |DAC (z) +PIC +PIC +PIC | +-----------------------------------------------------------------------------+ (a) Screen name (Request PREMIS Telephone Category) (b) Line ID number (Customer's 1st line, 2nd line, etc...)

OSCAR will store the data from BOSS or CARS for up to 30 years. OSCAR is operated with these PF keys: PF1 = Main Menu PF2 = Bill PF3 = Print Verification Screen (and duplicate bill printing) PF6 = Previous Bill PF7 = Next Bill PF11 = Forward/Backward The OSCAR Main Menu will look something like this: +-----------------------------------------------------------------------------+ |CMD (a) MSG (e) | | | | OSCAR/ONLINE | | MENU | | | | TN: (b) CUS: SUF: | | DATE: (c) PRINT RANGE: (f) FINAL: (g) | | ACCT CENTER: (d) SUBPEONA: (h) | | | | | | F1=MENU F2=BILL F3=PRINT F4=N/A F5=N/A F6=PREV | | F7=NEXT F8=N/A F9=N/A F10=N/A F11=F/B F12=N/A | +-----------------------------------------------------------------------------+ (a) Command section (b) Customer telephone number (c) Date (MMYY) (d) Account center (see below) (e) Message section (f) Print Range (number of months to print bills for) (g) Final (Y for final, blank for not final) (h) Reserved for the Subpeona Compliance Group Account Center codes are: CO Colorado and Wyoming NM New Mexico and Arizona NO North Dakota and Minnesota OR Oregon SO South Dakota, Nebraska, and Iowa UT Utah, Idaho, and Montana WA Washington PF2 will bring you to the first OSCAR Bill screen, which will look something like this: +-----------------------------------------------------------------------------+ |CMD MSG | | BILL P 1 S 1 | | BILL DATE: JUNE 23, 1996 | | ACCOUNT NUMBER: | | | | PAYMENT DUE JUL 12, 1996 | | 866 W.
