PRODUCT OVERVIEWPRODUCT OVERVIEW
• VCL, E3 34Mbps (OLTE) Optical Line Transmission Equipment converts and transports a ITU-T compliant standard E3, 34Mbps signal on optical fiber.
• Local and the Remote terminals can be monitored and controlled by a Windows based GUI (Graphical User Interface), from a single location.
• Auto Laser shut off facility.
• Powered by STM-1 grade Class I Laser - by Lucent Technologies.
The VCL, E3-OLTE is available in two configurations:
• With the option of 1+1 Optical Redundancy (Protection Switching).
• Without the option of Optical Redundancy (Protection Switching).
Valiant Communications Limited - 2006 Slide 3
• Single - card implementation.• 1+1 Optical Redundancy (Protection Switching) option.• Standard CCITT (ITU-T) compliant interfaces.• Auto Laser Shut Off facility.• Remote and local terminal monitoring and control through back panel by a
Network Management System.• Optional TCP / IP Remote Access for monitoring alarms and management• Extensive alarms and status indication facility.• Operates on nominal -48V DC input.• Distributed on-board power supply.• Microprocessor controlled with powerful diagnostic facilities for both remote
and local systems.• Powered by STM-1 grade Class I Laser - by Lucent Technologies.• Stored program controlled.• Highly reliable and compact.
