Loss of signal during VC3 service creation between OSN3500 and Jxxx Router.
OSN's D34S signal is normal.
Jxxx Router interface is Red.
Jxxx Router side present a LOS but OSN interface is normal: No alarm display.
Use the T2000V2R6 to adapt the bit rate of OSN3500 signal:
1- Right-click the NE--> choose "NE Explorer" --> Select the "PD3" board in the board list --> click on "Configuration" on board attribute
2- on the right side (By board window) double-click on the interface connected to Juniper (e.g 15-PD3:1) --> choose T3 --> equalized both the transmit & received signal.
OSN's PD3 interface present no alarm that means Transmit and receive status is normal.
Jxxx Router DS3 interface show a LOS --> transmit normal but can't receive/process signal by the PD3 card.
the problem is the signal rate: Jxxx Router DS3 interface process only T3 (45Mb/s) while OSN's PD3 card process E3/T3 but by default transmit E3 (34Mb/s) signal.
