Application
When the OptiX 155/622H uses the STM-1 optical interface board, the equipment can implement the following functions:
-
Forms rings or chains operating at the STM-1 rate.
-
Forms rings or chains operating at the STM-1 rate with other equipment, such as the OptiX 155/622 and the OptiX 2500+.
-
Provides STM-1 interfaces for interconnection with third-party equipment.
-
The SL1Q and SL1O boards do not support MSP but support SNCP. The SL1Q and SL1O boards are mainly connected to the low-level transmission equipment, such as the OptiX Metro 500 and the OptiX Metro 100.
