D.3.2 Slot Properties—MRC-12

Note

Note

The Slot Properties pane displays information about the Cisco ONS 15454 SONET and ONS 15454 SDH slot that is selected in the NE Explorer tree. Use this properties pane to change the module performance monitoring thresholds.

The MRC-12 multirate card (MRC) provides up to 12 OC-3/STM-1 ports, 12 OC-12/STM-4 ports, or 4 OC-48/STM-16 ports using Small Form-factor Pluggables (SFPs), in any combination of line rates. All ports are Telcordia GR-253 compliant. The SFP optics can use SR, IR, LR, coarse wavelength division multiplexing (CWDM), and DWDM SFPs to support unrepeated spans.

The ports operate at up to 2488.32 Mbps over a single-mode fiber. The MRC-12 card has 12 physical connector adapters with 2 fibers per connector adapter (Tx and Rx). The card supports VT payloads, STS-1 payloads, and concatenated payloads at STS-3c, STS-6c, STS-9c, STS-12c, STS-18c, STS-24c, STS-36c, or STS-48c signal levels. It is fully interoperable with the ONS 15454 G-Series Ethernet cards.

The card supports 1+1 unidirectional and bidirectional facility protection. It also supports 1+1 protection in 4-fiber BLSR applications for the ONS 15454 SONET and in 4-fiber MS-SPRing applications for the ONS 15454 SDH, where both span switching and ring switching might occur. You can provision this card as part of a BLSR, UPSR, or 1+1 linear configuration for the ONS 15454 SONET or an MS-SPRing, SNCP, or linear configuration for the ONS 15454 SDH.

Longer distances are possible in an amplified system using dispersion compensation.

MRC-12 cards can only protect another MRC-12 card if the card is in the same speed slot (drop or trunk slot) and if both ports have matching line rates. For example, port 1 of the MRC-12 card 1 will protect port 1 of the MRC-12 card 2 only if both ports are provisioned with the same rate (for example, OC12/STM-4). If the ports are provisioned with different rates, you cannot set a 1+1 protection.

You can install MRC-12 cards in Slots 1 through 6 and 12 through 17 with an XCVT, XC10G, XC-VXL-2.5G, XC-VXL-10G, or XC-VXC-10G card.

Note The MRC-12 card supports an errorless software-initiated cross-connect card switch when used in a shelf equipped with XC-VXL-2.5G, XC-VXL-10G, or XC-VXC-10G cards.
