Product Description:

Equipment Structure

The OptiX OSN 7500 equipment consists of the cabinet, cabinet doors, DC power distribution unit (PDU), subracks, orderwire phone fixing frame, boards, and cables. The OptiX OSN 7500 subrack can be installed in a 300 mm or 600 mm ETSI cabinet.

NOTE:

The difference between a general subrack, an enhanced subrack, and a type III subrack (2300 W) is with regard to applicable power boards. With different power boards, the two types of subracks support different maximum power consumption values.


Overview of Boards

This topic describes the appearances, dimensions, bar codes, and classification of the boards used on the OptiX OSN systems.

4.1  Appearances and Dimensions of the Boards


Different boards have different appearances and dimensions.

Table 4-1 provides information about the appearances and dimensions of the boards used on the OptiX OSN 7500.

Depth (mm) 220 110 220
Width (mm) 40 25.4 44
Note: The figure in the right cell shows the three dimensions. "H" and "W" indicate the height and width of the front panel respectively and "D" indicates the depth of the printed circuit board (PCB).



The bar code is attached to the front panel of a board. Figure 4-1 shows the bar code with a 16-digit manufacturing code.

NOTE:

The positions of bar codes vary according to boards. For details on the feature code of a board, see the topic that describes the feature code of the board.

Cross-Connect Boards and System Control Boards

This topic describes the system control boards and the cross-connect boards that have different capacities.

  • 6.1 PSXCSA
    This topic describes the version, application, functions, working principle, front panel, and technical specifications of the PSXCSA (super dual-plane cross-connect and timing board). This topic also describes how to configure and commission the PSXCSA.
  • 6.2 GSCC
    This topic describes the version, application, functions, working principle, front panel, and technical specifications of the GSCC (system control and communication board). This topic also describes how to configure and commission the GSCC.

6.1  PSXCSA

This topic describes the version, application, functions, working principle, front panel, and technical specifications of the PSXCSA (super dual-plane cross-connect and timing board). This topic also describes how to configure and commission the PSXCSA.

6.1.1  Version Description

PSXCSA is available in the following functional version: T1.

6.1.2  Application

The PSXCSA is a super cross-connect and synchronous timing board. The PSXCSA provides service grooming and clock input/output functions in theOptiX OSN 7500 system.

The cross-connect and synchronous timing board provides the timing information to the other boards in the system and grooms the services between SDH line boards, packet boards, or tributary boards.

Figure 6-1 shows the position of The cross-connect and synchronous timing board in the system.


6.1.3  Functions and Features

The PSXCSA board grooms services and inputs/outputs clock signals.

Cross-Connect Unit

Table 6-1 provides the functions and features of the cross-connect unit of the PSXCSA board.

Functions and Features Description
Basic functions

Implements 360 Gbit/s higher order cross-connection at the VC-4 level, 40 Gbit/s lower order cross-connection at the VC-12 or VC-3 level, 160 Gbit/s packet data cross-connect capacity, 160 Gbit/s packet access capacity, 280 Gbit/s access capability in TDM mode, and 160 Gbit/s access capability in packet mode.

Service processing
  • Supports the flexible service grooming and supports the cross-connect, multicast, and broadcast services.
  • Communicates with other boards.
  • Supports the tact switch and performs the protection switching without service interruption.
  • Supports the SNCP protection at the levels of VC-4-4c, VC-4-8c, VC-4-16c, VC-4-64c, VC-4, VC-12, VC-3, and AU-3.
