OP-4T1 from RAD
OP-4T1 / Optimux-4T1 is a multiplexercombining up to four T1channels over a single fiber optic link. A pair of OP-4T1 / Optimux-4T1 units offers simple and low-cost connectivity for four T1channels at distances up to 75 km (46 miles).
Various optical interfaces are available:
850 nm for multimode fiber
1300 nm for single mode or multimode fiber
1300 nm laser and 1550 nm laser for extended range over single mode fiber
1300/1550 nm for single fiber, WDM(Wavelength Division Multiplexing) operation (standalone version only).
An optional second link provides backup, using automatic switchover upon main link failure.
An optional second power supply provides power redundancy and fail-safe operation.
OP-4T1 / Optimux-4T1 transmits each of the T1channels independently, so that each T1channel can have a different clocksource.
OP-4T1 / Optimux-4T1 is also available as a card for the LRS-24 19-inch rack with central SNMP management. This option provides a compact, cost-effective central solution.
To facilitate system diagnostics, OP-4T1 / Optimux-4T1 features LEDstatus indicators, AISalarm generation and recognition, and dry contact closure upon link failure.
Setup, control and diagnostics can be performed via a supervisory port using an ASCIIterminal, or a SLIP connection to an SNMPmanagement station. Optimux-4T1 in the LRS-24 rack can also be configured, maintained and monitored over Ethernet, via the LRS-24's CL-2 card.
Optimux-4T1 can be managed by:
RADview-PC running on a PC/Windows
RADview-HPOV running on an HP OpenView UNIX platform.
A voice service channel is available for end-to-end communication between maintenance personnel.
The standalone Optimux-4T1 is available as a compact 1Uhigh unit that can be mounted in a 19-inch rack.
