OCB-283
All new technology based on stored program control switching systems
concept. Call processing is distributed across different management programmes
the organs of the system and is stored in ROM/RAM different control units.
Processor control units using stored in the program and the date of
United ROM/RAM and call handling process. Treatment or processing by using the call
ultimately, put in a page link to switch between the I/C/g and ends. According to
naming conventions and architectures of control units and switch April change, but a criterion
Balances to switch more or less the same.
The distinctive features of the system:
1. This is the only digital switching with an anchor "t" switch a maximum of 2048.
PCM may be connected.
2. it supports both analog and digital subscribers.
3. it supports all existing signalling systems, such as decades, MF (R2), CAS
CCITT also no. 7 signaling system.
4. It provides telephony, ISDN, data transmission, mobile radio communications, as well as other
value added services.
5. the system has automatic recovery function. When a serious violation occurs
The control unit, it gives a message for EMS.EMS puts this unit does not work,
Download software of this unit for backup unit and bring it into operation.
Program diagnosis work on the failed unit and diagnostic is printed on
Terminal.
6. He has dual remote MAY BE a facility.Subscribers access device, located on the
remote location and connected to the main Exchange links PCM. In addition,
can also be placed line hubs in a remote location and connected to the
CSNL or CSND through RSM.
7. various entities of the DESIGN system is connected through 283 symbolic rings. It's
allows the rapid exchange of information and avoids the complex linkages and cables
Among the various units.
8. charge subscribers ' accounts are automatically saved to disk when
on the day. This allows you to avoid the loss of income in the event of failure of the battery.
9. bandwidth traffic system is enormous.
10. an Exchange can be performed locally or from the NMC through 64
Kbps communication line.
11. all control units are of the same type are implemented in hardware. It's
Call the station.
12. the system consists of only 35 types of cards. This eliminates the maps
required for CSN. Therefore, the number of spare cards must be kept for
maintenance is dramatically reduced.
13. the system has a modular structure expansion can be very easily transferred
by adding the necessary hardware and software.
14. the SMMS is duplicated with one other active standby mode. In the event of a fault,
automatically switch.
15. hard drive are very small in size, compact and maintenance. He has a
very huge amount of memory 1.2 Giga bytes.
16. very little Space requirement.
17. There is no fixed or rigid strut and system configuration.
