MXP_MR_10DME_C and MXP_MR_10DME_L Card Description
The MXP_MR_10DME_C and MXP_MR_10DME_L muxponder cards aggregate a mix of storage access networking (SAN) service client inputs (GE, FICON, and Fibre Channel) into one 10.0 Gbps STM-64/OC-192 DWDM signal on the trunk side. The MXP_MR_10DME_C and MXP_MR_10DME_L cards pass all SONET/SDH overhead bytes transparently. Each card provides one long-reach STM-64/OC-192 port and is compliant with Telcordia GR-253-CORE and ITU-T G.957. You can install MXP_MR_10DME_C and MXP_MR_10DME_L cards in Slots 1 to 6 and 12 to 17. Each ONS 15454 shelf assembly can accomodate up to 12 cards.
Note On the card faceplates, the MXP_MR_10DME_C and MXP_MR_10DME_L cards are displayed as 10DME_C and 10DME_L, respectively.
Note The MXP_MR_10DME_C and MXP_MR_10DME_L cards are not compatible with the MXP_2.5G_10G card, which does not support full optical transparency.
Feature Summary
For detailed information about card features refer to the Cisco ONS 15454 DWDM Reference Manual.
The MXP_MR_10DME_C and MXP_MR_10DME_L cards have the following high-level features:
•Onboard E-FEC processor: The processor supports both standard RS (specified in ITU-T G.709) and E-FEC, which allows an improved gain on trunk interfaces with a resultant extension of the transmission range on these interfaces. The E-FEC functionality increases the correction capability of the transponder to improve performance, allowing operation at a lower OSNR compared to the standard RS (237,255) correction algorithm. A new BCH algorithm implemented in E-FEC allows recovery of an input BER up to 1E-3.
•Pluggable client interface optic modules: The MXP_MR_10DME_C and MXP_MR_10DME_L cards have modular interfaces. Two types of optics modules can be plugged into the card. These include an OC-48/STM 16 SR-1 interface with a 7-km (4.3-mile) nominal range (for short range and intra-office applications) and an IR-1 interface with a range up to 40 km (24.9 miles). SR-1 is defined in Telcordia GR-253-CORE and in I-16 (ITU-T G.957). IR-1 is defined in Telcordia GR-253-CORE and in S-16-1 (ITU-T G.957).
•Y-cable protection: Supports Y-cable protection between the same card type only, on ports with the same port number and signal rate. See the Cisco ONS 15454 DWDM Reference Manual for more detailed information.
•High level provisioning support: The cards are initially provisioned using Cisco MetroPlanner software. Subsequently, the card can be monitored and provisioned using CTC software.
•Automatic laser shutdown: A safety mechanism used in the event of a fiber cut.
•Link monitoring and management: The cards use standard OC-48 OH bytes to monitor and manage incoming interfaces. The cards pass the incoming SDH/SONET data stream and its OH bytes transparently.
•Control of layered SONET/SDH transport overhead: The cards are provisionable to terminate regenerator section overhead. This is used to eliminate forwarding of unneeded layer overhead. It can help reduce the number of alarms and help isolate faults in the network.
•Automatic timing source synchronization: The MXP_MR_10DME_C and MXP_MR_10DME_L cards normally synchronize from the TCC2/TCC2P card. If for some reason, such as maintenance or upgrade activity, the TCC2/TCC2P is not available, the cards automatically synchronize to one of the input client interface clocks.
•Configurable squelching policy: The cards can be configured to squelch the client interface output if there is LOS at the DWDM receiver or if there is a remote fault. In the event of a remote fault, the card manages MS-AIS insertion.
•The cards are tunable across the full C band (MXP_MR_10DME_C) or full L band (MXP_MR_10DME_L), thus eliminating the need to use different versions of each card to provide tunability across specific wavelengths in a band.
Signal Types
The cards support aggregation of the following signal types:
•1-Gigabit Fibre Channel
•2-Gigabit Fibre Channel
•4-Gigabit Fibre Channel
•1-Gigabit Ethernet
•1-Gigabit ISC-Compatible (ISC-1)
•2-Gigabit ISC-Peer (ISC-3)
Note Because the client payload cannot oversubscribe the trunk, a maximum of 10-Gbps of mixed client signals can be accepted.
Digital Wrapper
The digital wrapper function (ITU-T G.709-compliant) formats the DWDM wavelength so that it can be used to set up generic communication channels (GCCs) for data communications, enable forward error correction (FEC), or facilitate performance monitoring (PM). The MXP_MR_10DME_C and MXP_MR_10DME_L cards work with the OTN devices defined in ITU-T G.709. The cards support ODU1-to-OTU2 multiplexing, which is an industry standard method for asynchronously mapping a SONET/SDH payload into a digitally wrapped envelope.
Client and Trunk Ports
The MXP_MR_10DME_C card features a tunable 1550-nm C-band laser on the trunk port. The laser is tunable across 82 wavelengths on the ITU grid with 50-GHz spacing between wavelengths. The MXP_MR_10DME_L features a tunable 1580-nm L-band laser on the trunk port. The laser is tunable across 80 wavelengths on the ITU grid, also with 50-GHz spacing. Each card features four 1310-nm lasers on the client ports and contains five transmit and receive connector pairs (labeled) on the card faceplate. The cards uses dual LC connectors on the trunk side and uses small-form factor pluggable (SFP) modules on the client side for optical cable termination.
Data Rates
Table 1 shows the input data rate for each client interface and the encapsulation method. The current version of the GFP-T G.7041 supports transparent mapping of 8B/10B block-coded protocols, including Gigabit Ethernet, Fibre Channel, ISC, and FICON.
In addition to the GFP mapping, 1-Gbps traffic on Port 1 or 2 of the high-speed SERDES is mapped to an STS-24c channel. If two 1-Gbps client signals are present at Port 1 and Port 2 of the high-speed SERDES, the Port 1 signal is mapped into the first STS-24c channel and the Port 2 signal into the second STS-24c channel. The two channels are then mapped into an OC-48 trunk channel.

There are two FPGAs on each MXP_MR_10DME_C and MXP_MR_10DME_L, and a group of four ports is mapped to each FPGA. Group 1 consists of Ports 1 through 4, and Group 2 consists of Ports 5 through 8. Table 2 shows some of the mix and match possibilities on the various client data rates for Ports 1 through 4 and Ports 5 through 8. An X indicates that the data rate is supported in that port.

Performance Monitoring
GFP-T PM is available through RMON and trunk PM is managed according to Telcordia GR-253-CORE and ITU G.783/826. Client PM is achieved through RMON for FC and GE.
Distance Extension
A buffer-to-buffer credit management scheme provides FC flow control. With this feature enabled, a port indicates the number of frames that can be sent to it (its buffer credit), before the sender is required to stop transmitting and wait for the receipt of a "ready" indication The MXP_MR_10DME_C and MXP_MR_10DME_L cards support FC credit-based flow control with a buffer-to-buffer credit extension of up to 1600 km (994.1 miles) for 1G FC, up to 800 km (497.1 miles) for 2G FC, or up to 400 km (248.5 miles) for 4G FC. The feature can be enabled or disabled.

Wavelength Identification
The card uses trunk lasers that are wavelocked, which allows the trunk transmitter to operate on the ITU grid effectively. Both the MXP_MR_10DME_C and MXP_MR_10DME_L cards implement the UT2 module. The MXP_MR_10DME_C card uses a C-band version of the UT2 and the MXP_MR_10DME_L card uses an L-band version.
Table 3 describes the required trunk transmit laser wavelengths for the MXP_MR_10DME_C card. The laser is tunable over 82 wavelengths in the C band at 50-GHz spacing on the ITU grid.

Card-Level Indicators
Table 5 describes the three card-level LEDs on the MXP_MR_10DME_C and MXP_MR_10DME_L cards.
Table 5 MXP_MR_10DME_C and MXP_MR_10DME_L Card-Level Indicators
Card-Level LED
|
Description
|
Red FAIL LED
|
The red FAIL LED indicates that the card's processor is not ready. This LED is on during reset. The FAIL LED flashes during the boot process. Replace the card if the red FAIL LED persists.
|
ACT/STBY LED
Green (Active)
Amber (Standby)
|
If the ACT/STBY LED is green, the card is operational (one or more ports active) and ready to carry traffic. If the ACT/STBY LED is amber, the card is operational and in standby (protect) mode.
|
Amber SF LED
|
The amber SF LED indicates a signal failure or condition such as LOS, LOF, or high BERs on one or more of the card's ports. The amber SF LED is also on if the transmit and receive fibers are incorrectly connected. If the fibers are properly connected and the link is working, the light turns off.
|
Port-Level Indicators
Table 6 describes the port-level LEDs on the MXP_MR_10DME_C and MXP_MR_10DME_L cards.
Table 6 MXP_MR_10DME_C and MXP_MR_10DME_L Port-Level Indicators
Port-Level LED
|
Description
|
Port LED
(eight LEDs, four for each group, one for each SFP)
Green/Red/Amber/Off
|
When green, the port LED indicates that the client port is either in service and receiving a recognized signal (that is, no signal fail), or Out of Service and Maintenance (OOS,MT or locked, maintenance) and the signal fail and alarms are being ignored.
When red, the port LED indicates that the client port is in service but is receiving a signal fail (LOS).
When amber, the port LED indicates that the port is provisioned and in a standby state.
When off, the port LED indicates that the SFP is either not provisioned, out of service, not properly inserted, or the SFP hardware has failed.
|
Green DWDM LED
|
The green DWDM LED indicates that the DWDM port is in service and that it is receiving a recognized signal.

Install the MXP_MR_10DME_C and MXP_MR_10DME_L Cards
Warning During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself. Statement 94
Warning Class I (CDRH) and Class 1M (IEC) laser products. Statement 1055
Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 272
Note If protective clips are installed on the rear connectors of the cards, remove the clips before installing the cards.
Note If you install a card incorrectly, the FAIL LED flashes continuously.
Figure 2 shows general card installation.
Figure 2 Installing a Card in the Cisco ONS 15454 SONET (ANSI) Shelf Assembly
Step 1 Display the card installation plan for the node using one of the following sources:
•The Cisco MetroPlanner Site Dialog window for the node you are provisioning.
•CTC node view with slots preprovisioned based on the Cisco MetroPlanner Site Dialog window.
•Written slot plan. The plan must be based on the Cisco MetroPlanner Site Dialog window for your installation.
Step 2 Remove the card from its packaging, then remove the protective clips from the card's rear connectors.
Step 3 Open the card latches/ejectors.
Step 4 Use the latches/ejectors to firmly slide the card along the guide rails until the card plugs into the receptacle at the back of the slot.
Step 5 Verify that the card is inserted correctly and close the latches/ejectors on the card.
Note It is possible to close the latches and ejectors when the card is not completely plugged into the chassis. Ensure that you cannot insert the card any further.
Step 6 Verify the LED activity:
•The red FAIL LED turns on for 20 to 30 seconds.
•The red FAIL LED blinks for 35 to 45 seconds.
•All LEDs blink once and turn off for 5 to 10 seconds.
•The ACT or ACT/STBY LED turns on. The SF LED can persist until all card ports connect to their far-end counterparts and a signal is present.
Step 7 If the card does not boot up properly, or the LED activity does not occur as described in Step 6, check the following:
•When a physical card type does not match the type of card provisioned for that slot in CTC, the card might not boot. If the card does not boot, open CTC and ensure that the slot is not provisioned for a different card type before assuming that the card is faulty.
•If the red FAIL LED does not turn on, check the power.
•If you insert a card into a slot provisioned for a different card, all LEDs turn off.
•If the red FAIL LED is on continuously or the LEDs behave erratically, the card is not installed properly. Remove the card and repeat Steps 3 to 6.
Stop. You have completed this procedure.

(S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:

For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
