Cisco Cisco ONS 15454 SDH Multiservice Provisioning Platform (MSPP) Guía De Instalación

You can group and map E1-N-14 card traffic in VC-12 as per ITU-T G.707 to any other card in an ONS 
15454 SDH node. For performance-monitoring purposes, you can gather bidirectional E-1 frame-level 
information (loss of frame, parity errors or CRC errors, for example). 

The lowest level cross-connect is STM-1. Lower level signals, such as E-1, DS-3, or E-3, can be dropped. 
This may leave part of the bandwidth unused. 

The E1-N-14 card faceplate has three LEDs.

You can obtain the status of the fourteen E-1 ports using the LCD screen on the ONS 15454 SDH fan 
tray assembly. Use the LCD to view the status of any port or card slot; the screen displays the number 
and severity of alarms for a given port or slot. Refer to 

Chapter 1, “Alarm Troubleshooting,”

 of the 

“Cisco ONS 15454 SDH Troubleshooting and Maintenance Guide, R3.3” for a complete description of 
the alarm messages.

Red FAIL LED

The red FAIL LED indicates the card’s processor is not ready. This LED is 
lit during Reset. The FAIL LED flashes during the boot process. Replace 
the card if the FAIL LED persists.

ACT/STBY LED

Green (Active)

Yellow (Standby)

The ACT/STBY LED indicates when the E1-N-14 card is operational and 
ready to carry traffic (green) or when the card is in standby mode (yellow). 

Yellow SF LED

 The yellow SF LED indicates a signal failure or condition such as LOS, 
LOF or high BERs on one or more of the card’s ports.
