PT-50S(3U) PCM Equipment

Product Description

1       General Introduction PT**0S (3U) PCM Multiplexeradopts 3U high standard *9" rack. It supports multiple analog and data access, and fiber/electronic integration. The maximum*4Kbpsaccess capacity of PT**0S (3U) PCM Multiplexer is *4, and the maximum E1 access capacity is *4 as well.
PT**0S (3U) PCM Multiplexercan connect with other transmission equipment through its optical interface or standard E1 interface. It can realize point to point communication by E1 or optical interface; and it can execute D/I (drop/inset) function through its own *4E1 cross connection matrix; and it can realize PABX function with its relay card; and it can have online test functions including remote channel circuit test and 2 wire subscriber line test.
PT**0S (3U) PCM Multiplexeris provided with a powerful NMS system, by which the operating status of the network can be monitored in real time and the functions including malfunction locating, time slot reassignment and online test can be performed easily. There are two methods for network management information transmission: if the PT serial products are located in the same room, these PT serial products can be connected directly via RS**2 port, if the PT serial products are located in different rooms, they can be connected through TS0 of E1 interface. The NMS platform connects with PT serial products by RS**2 port or Ethernet interface, the graphic interface network management, command line network management or SNMP network management can be realized. 2       Main features 2.1   High density The system capacity is *4 *4Kbps channels. And the maximum access capacity of E1 interface is also *4. 2.2   Abundant Access Interfaces PT**0S (3U) PCM multiplexersupports different types of user services: *4Kbps co-directional and N×*4Kbps synchronous data interface, *0/**0M Ethernet interface, RS**2 and RS**5 asynchronous data interface, FXO, FXS, Hotline, Magneto, Carrier wave magneto interface and 2/*-wire E&M interface, etc.
  2.3   Powerful Net Management System It is convenient to set cross connection and the level of analog interface, and read the devices’ settings by the NMS system.
Automatic online test function can realize the level test and signaling test for analog interface, the functional tests for data interfaces, and the functional tests of A/B ground, short circuit for external lines, it is very convenient to locate malfunction quickly and correctly through the NMS system. 2.4   DI(drop/insert) function The DI function can be configured by software, which makes it very flexible to drop or insert channels. 2.5   PABX function The PABX function can be realized by the Relay card, the relay card will support China No.1 signaling, No.7 signaling, PRI signaling and V5 signaling. 2.6   Optional OPT optical transmission unit The OPT Optical transmission card can be selected by customer to reduce the equipment cost of the whole transmission system. The E1 interface of the PT**0S (3U) PCM multiplexer can be transmitted by the optical card. There are two types of OPT optical card: one is OPT*8E1 card, the OPT*8E1 card has 8E1 interfaces that will be transmitted by the optical interface, and these 8 E1 interface will enter *4E1 cross connection directly. The other type is OPT*4E**4ETH card, its 8 E1 and 4 ETH will be transmitted via the optical interface, therein 4E1 will be transmitted directly, and the other 4E1 will enter *4E1 cross connection of the system. 2.7   Supper Reliability All key cards adopt redundant backup and support hot swappable, including power supply cards, ring supply cards and master cards.
 
The PT**0S (3U) PCM Multiplexer adopts advanced circuit design and modular structure design, it uses low power consumption, high reliable components, and all functional cards support hot swap as well. 2.8   Unique ID card design The ID card is fixed in the shelf; it can identify the equipment’s ID, and store the configuration data file and dynamic operating data. So if changing other functional cards will not influence NMS to identify the equipment, which makes it more stable during switching master control cards.
