Kako vec znate u ovom serijalu textova vam opisujem centrale koje se koriste kod
nas pa je na red dosla i ova :p
EWSD system je mocan i flexibilan digitalni system koji ce predvidjen za generalnu
upotrebu u telekomunikacijama. Pa samim tim sto je "mocan" mi zelimo da znamo
vise o njemu. U BaCk-ovom textu ste se vec sreli sa ovom centralom, ali ja cu
sada da pokusam da vam je jos vise priblizim. Proizvodjac ove centrale je Siemens.

zlonamerne svrhe. Tekst je pisan u cilju edukacije citalaca i svih znatizeljnika,
pogotovo u ovom polju gde nam informacije i nisu bas mnogo dostupne.
* Neke delove cu ostaviti na engleskom jer tokom prevoda
* neke fraze gube smisao ...
////////////////////////////////////////////////////////////////////////////////
--==<[ Opste karakteristike
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
Osnovne mogucnosti EWSD centrale su sledece :
- Gradski saobracaj (Local Exchange), postoji mogucnost povezivanja od nekoliko
pa do 250 hiljada korisnika.
- Tranzitne centrale, ovo su centralni cvorovi u telefonskoj mrezi, svaka
centrala moze da primi do 60000 linija.
- Internacionalni saobracaj, ova aplikacija omogucava sve specijalne funkcije
za funkcionisanje internacionalnog saobracaja.
- Bazna stanica za mobilne korisnike moze opsluzivati do 8000 radio telefona
- Rural, Swithing system, Digital Network sa ISDN-om, Specijalni servisi ...
Jedna od vrlo bitnih karakteristika EWSD centrale je strategija samostalnog
nadziranja i otklanjaja gresaka ili obavestavanja zaduzenog organa. Zatim tu
su laka integracija u bilo koji telefonski sistem i alternativno biranje puteva
za komukaciju, podaci se mogu prenositi jednim putem ili preko jos 7
alternativnih.

--==<[ Arhitektura systema
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
Ovaj system je veoma flexibilan i ekonomican. Daje vam mogucnost kombinacije
raznih podsistema i sirok sprektar mogucih aplikacija. Osnovni delovi jednog
ovakvog systema su:
DLU - Digital user's block
LTG - Linear group
CCNC - The device of management of a network of the signal system
SN - Switching field
CP - Coordinate processor
SC-MUX - The converter of signals
SM - Service module
AL - Analog lines
ISDN - Digital network of the integrated service
MB - Buffer ( memorija )
SYP - System panel
OMT - Terminal of the operator
***
- Coordinate processor (CP) upravlja bazom podataka, konfigurise i koordinira
svim funkcijama, npr:
- cuvanjem i menadzmentom svih programa i podataka
- procesiranjem i primanjem informacija o rutiranju,
zonama, tarifiranju...
- comuniciranje sa glavnim centrom
- nadgledanje svih ostalih podsystema

MYB - Bank of memory
MYC - Management of memory
PU - The processor (module)
EM - An external memory for resident programs and the
data under the account of cost of conversations.
***
- Digital user's module (DLU) je zaduzen za rad sa pretplatnicima,
on prati promet izmedju korisnika, prilagodjava system trenutnim
zahtevima i takodje omogucava ISDN.
Osnovni sklopovi su:
SLMD - Digital conections modul

MTA - The external test equipment
4096 bus - Trunks between modules of user's lines and managing devices
CG - The clock generator
BDE - The allocator of trunks
SASC - Support RDLU in emergency operation
EMSP - A set at failures
ALEX - The controller of gauges of the removed alarm system
RGMG - The generator of a calling current
***
- Linear group (LTG) predstavlja interfejs izmedju SN (Switching field) i
spoljasnih prikljucaka koji mogu biti:
- User's lines
- Digital connecting lines
- Analog connecting lines through the multiplexer (SC-MUX)
Osnovni sklopovi su:
- The group processor (GP), routine operations on switching streams
- Group switch GS (the colloquial multiplexer (SPMX)
- The interface of connection with a switching field (LIU)
- The alarm block (SU) for acoustic signals, voltage,
signal system MCHK, a multifrequency set and test access.
- Digital interfaces (DIU)
***
- The Switching Field (SN), prilikom maximalne konfiguracije
ovaj system moze da izvrsi konekciju izmedju 504 linernih
grupa, 25200 korisnickih linija kroz 7 razlicitih tipova modula.
Naravno postoje mogucnosti prosirivanja dodavanjem specijalnih
modula.
Osnovni sklopovi su :
TSI - The time switchboard of reception
TSO - The time switchboard of transfer
SSM - A part of spatial switching
SN0, SN1, ... branch of system

Kao sto sam vec rekao ovaj sistem ima mogucnost samostalne provereve sistema,
davanje obavestanja o stanju sistema, samostalnom resavanju nekih softverskih
problema,...
U slucaju hardverskog kvara, na systemskom panelu (SYPD) mozemo videte detalje
o kvaru. Ovde imamo mogucnost da vidimo na kojem modulu se desio kvar, da
iskljucimo alarm, ili ako je potrebno da iskljucimo ceo system,... Zatim preko
OMT-a pristupamo systemu EWSD-a i mozemo videti listing u kome mozemo videti
detalje o kvaru.
Evo primera jednog listinga :

OMT je ustvari terminal kojim vi pristupate i upravljate EWSD sistemom, on moze
biti lokalni ili udaljeni sve zavisi od lokacije sistema. Ako je udaljeni onda
se na njega povezujete preko modema.
Ako ste na EWSD centrali ostaje vam samo da nadjete prustupni broj, njega mozete
naci preko neko wardialera ili na neki SE nacin.
Nasli ste broj? E sada se konektujte ... nije potreban nikakav dodatni softver
sve vec imate (ne necu da kazem sta imate).
////////////////////////////////////////////////////////////////////////////////
--==<[ Some commands
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
Kao sto je rekao BaCk, kada prvi put pristupate sistemu naicicete na login proceduru:
PLEASE ENTER USERID.
<EWSD1
PLEASE ENTER CURRENT PASSWORD
(AND OPTIONALLY A NEW ONE SEPARATED BY BLANK).
<
Dalje mozete pogledati listu fajlova sa DISPTRAFICH, posle svake naredbe obavezno
ide ';'
EWSD centrala pravi tri osnovne grupe fajlova i to:
HF.ARCHIVE - zapisi o alarmnim stanjima na uredajima za napajanje, ispadi
prenosnih sistema i greske registrovane unutar komutacionog sistema.
TS.DEST - saobracajni podaci po definisanim destinicijama.
TS.TGRP - saobracajni podaci po prenosnickim grupama (TGNO).
Pristup i iscitavanje informacije koje se cuvaju u nekom od ovihfajlova se
vrsi pomocu komande GETTRAFILE :
GETTRAFILE:FILE = <ImeFajla>, <Parametari>;
Parametri se odvajaju zarezom i mogu biti :
BEG=? - Pocetak merenja
TER=? - Kraj merenja
IV =? - Interval merenja
Da bi uopste videli sta ima u ovim fajlovima prvo moramo da zadamo komandu
kojom cemo otpoceti snimanje tj pracenje i ona izgleda ovako :
REC <object>:UNIT = <receiver>, <Parametri>;
Gde je :
<Object> = LTG, CP, CCNC, DLU, TGRP, DEST
UNIT = OMT-terminal, MDD-hard disk
PER = Period merenja (MO-SU or WO, HO-holidays)
BEG=? - Pocetak merenja
TER=? - Kraj merenja
IV =? - Interval merenja
Komandom DISPALARM; mozemo videti stanje svih alarma na sistemu :
...
MASKNO:07714
OBJECT= DLU ALPRIO = MAJOR ALSTAT = IP
MSGNO = 1070
ALTYPE= EQUIPMENT ALARM
PABCAUSE= REPLACEABLE UNIT TYPE MISMATCH
ALARM-ID: CLASS=DLUEQ DLU=250 EQ=EQG -1 SIDE=0
OBJECT= DLU ALPRIO = MAJOR ALSTAT = IP
MSGNO = 1068
ALTYPE= EQUIPMENT ALARM

OBJECT= DLU ALPRIO = MAJOR ALSTAT = IP
MSGNO = 1029
ALTYPE= EQUIPMENT ALARM
PABCAUSE= REPLACEABLE UNIT TYPE MISMATCH
...
Mozemo zakljuciti da komande koje pocinju sa DISP sluze za pregled fajlova i
stanja systema.
Evo jedne zanimljive DISPAUTCL, sa ovom komandom mozete da izlistate spisak
svih ostalih komandi.
Evo jedne bas zanimljive DISPCONN, sta mislite sta radi? Pa sa njom mozete da
vidite ko sa kime prica... ;)

Xexe, imate sve sto vam treba, samo malo mucnite glavom i to je to (razumece onaj
koji treba da razume).
Pazite sta radite, dosta komandi se loguje na centrali, vecinom su to naredbe
koje pocinju sa EDIT (kontamo svi zasta sluze, zar ne?) Zatim neke pogresne akcije
mogu aktivirati alarm, pazite sta radite sa EQN parametrom. Da bi sacuvali
prethodne postavke pre nego sto nesto menjate, a bolje da to ne radite, koristite
DISPSDNDAT da bi kasnije mogli sve da ispravite.
Ako imate pitanja, predloge, materijal, bilo sta ... samo pustite email.
I naravno vidite sta sve ima u nasim labaratorijama:
