Optimux-45L 21 E1 or 28 T1 over T3 or fiber multiplexer provides a highly cost-effective and simple solution for transporting multiple E1 and T1 links, as well as a combination of E1 and T1 (according to ITU G.747), on a 45 Mbps data stream. Its flexibility offers a solution for a broad range of applications.

Range of applications and options

The Optimux-45L 21 E1 or 28 T1 over T3 or fiber multiplexer is a low-cost version of the Optimux-45 with Telco connectors as the user interface. The Optimux-45L is optimized for point-to-point or point-to-network applications. This unit provides low-cost connectivity of 21 E1 or 28 T1 lines or any combination of E1 and T1.

The product is non-modular and offers redundant power supply, enhancing system reliability. In addition, an optional secondary link provides backup using automatic switchover upon main link failure.

Supports both electrical and optical interfaces

The product’s main link supports both electrical and optical interface options. The electrical interface has BNC connectors in conformance with G.703 standards.

The optical interface supports the following options:

• 850 nm for multimode fiber
• 1310 nm for multimode fiber
• 1310 nm and 1550 nm laser for extended range over single mode fiber
• 1310 nm and 1550 nm long haul single fiber option (WDM)
• Single fiber/wavelength option

Advanced management, control and diagnostics

To facilitate system diagnostics, the Optimux-45L features LED status indicators as well as AIS alarm generation, recognition and dry contact closure upon link failure. In addition, the Optimux-45L M13 multiplexer’s setup, control and diagnostics can be performed through a supervisory port using an ASCII terminal, Telnet host, Web terminal, or from an SNMP management station via a dedicated management port (Ethernet or RS-232).

The SNMP management application offers:

• RADview-PC/TDM running in a Windows environment
• RADview-HPOV/TDM for HP OpenView UNIX platforms

The T3 link via an optional clock interface can be locked onto an external station clock.

The product supports various performance statistics on the T3, T1 and E1 lines.

The Optimux-45L 21 E1 or 28 T1 over T3 or fiber multiplexer is available as compact 1U-high unit for mounting in a 19" rack.
