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.

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.
