The ONS 15454 SDH FMEC STM1E 1:1 card provides front mount electrical connection for 2 x 12 ITU-compliant, G.703 STM1E ports. Ports 9 to 12 can be switched to E-4 instead of STM-1 (via CTC, on the STM1E-12 card). With the FMEC STM1E 1:1 card, each interface of an STM1E-12 card operates at 155.52 Mbps for STM-1 or 139.264 Mbps for E-4 over a 75-ohm unbalanced coaxial 1.0/2.3 miniature coax connector. The FMEC STM1E 1:1 card is required if you want to use the STM1E-12 card in 1:1 protection mode or for connection to two unprotected STM1E-12 cards.

Figure 3-16 shows the FMEC STM1E 1:1 faceplate and block diagram.

Figure 3-16 FMEC STM1E 1:1 Faceplate and Block Diagram

You can install the FMEC STM1E 1:1 card in any EFCA slot pair (18/19, 20/21, 26/27, or 28/29) on the ONS 15454 SDH. Each FMEC STM1E 1:1 card interface features STM1-level inputs and outputs supporting cable losses of up to 12.7 dB at 78 MHz.

3.16  FMEC-BLANK Card

The FMEC-BLANK card provides EMC emission control for empty FMEC slots. It also provides a way to close off the EFCA area, thus allowing air flow and convection to be maintained through the EFCA. Figure 3-17 shows the FMEC-BLANK card faceplate.

You must install the BLANK FMEC in every empty FMEC slot to maintain EMC requirements of the system and proper air flow.

3.17  MIC-A/P FMEC

The MIC-A/P FMEC provides connection for the BATTERY B input, one of the two possible redundant power supply inputs. It also provides connection for eight alarm outputs (coming from the TCC2/TCC2P card), sixteen alarm inputs, and four configurable alarm inputs/outputs. Its position is in Slot 23 in the center of the subrack EFCA area. Figure 3-18 shows the MIC-A/P faceplate and block diagram.

Figure 3-18 MIC-A/P Faceplate and Block Diagram

The MIC-A/P FMEC has the following features:

•Connection for one of the two possible redundant power supply inputs

•Connection for eight alarm outputs (coming from the TCC2/TCC2P card)

•Connection for four configurable alarm inputs/outputs

•Connection for sixteen alarm inputs

•Storage of manufacturing and inventory data

---

Note For proper system operation, both the MIC-A/P and the MIC-C/T/P FMECs must be installed in the ONS 15454 SDH shelf.

---

---

Note The MIC-A/P card controls whether FMEC cards on its side of the shelf appear in the CTC graphical user interface (GUI). For example, if the MIC-A/P is removed from the shelf, FMECS to the left of the card may disappear in CTC. This is normal behavior because when the MIC-A/P card is removed, communication can no longer be established with the disappeared FMECS. For more information, refer to the IMPROPROMVL entry in the "Alarm Troubleshooting" chapter of the Cisco ONS 15454 SDH Troubleshooting Guide.
