TXP_MR_10E_C and TXP_MR_10E_L Card Description
The TXP_MR_10E_C and TXP_MR_10E_L cards are multirate transponders for the ONS 15454 platform. The cards are fully backward compatible with the TXP_MR_10G and TXP_MR_10E cards. They process one 10-Gbps signal (client side) into one 100-GHz DWDM signal (trunk side). The TXP_MR_10E_C is tunable over the entire set of C-band wavelength channels (82 channels spaced at 50 GHz on the ITU grid). The TXP_MR_10E_L is tunable over the entire set of L-band wavelength channels (80 channels spaced at 50 GHz on the ITU grid) and is well suited for use in networks that employ DS fiber or SMF-28 single-mode fiber. You can install TXP_MR_10E_C and TXP_MR_10E_L cards in Slots 1 to 6 and 12 to 17.
Key Features
The key features of the TXP_MR_10E_C and TXP_MR_10E_L cards are:
•A tri-rate client interface (available through the ONS-XC-10G-S1 XFP, ordered separately):
–OC-192 (SR1)
–10GE (10GBASE-LR)
–10G-FC (1200-SM-LL-L)
•A UT2 module tunable through the entire C band (TXP_MR_10E_C card) or L band (TXP_MR_10E_L card). The channels are spaced at 50 GHz on the ITU grid.
•OC-192 to ITU-T G.709 OTU2 provisionable synchronous and asynchronous mapping.
•Client interfaces: The client interface is implemented with a separately orderable XFP module. The module is a tri-rate transceiver, providing a single port that can be configured in the field to support an OC-192 SR-1 (Telcordia GR-253-CORE) or STM-64 I-64.1 (ITU-T G.691) optical interfaces, as well as 10GE LAN PHY (10GBASE-LR), 10GE WAN PHY (10GBASE-LW), or 10G-FC signals. The XFP supports LC connectors and is equipped with a 1310-nm laser.
•Y-cable protection: This protection mechanism provides redundant bidirectional paths. Two cards can be joined in a Y-cable protection group with one card assigned as the working card and the other defined as the protection card. The Y-protection mechanism is provisionable and can be set ON or OFF (OFF is the default mode). When a signal fault is detected, the protection mechanism software automatically switches between paths.
•E-FEC capability: A key feature of the TXP_MR_10E_C and TXP_MR_10E_L cards is the availability to configure the forward error correction in three modes: NO FEC, FEC, and E-FEC. The output bit rate is always 10.7092 Gbps as defined in ITU-T G.709, but the error coding performance can be provisioned as follows:
–NO FEC—No forward error correction
–FEC—Standard ITU-T G.975 Reed-Solomon algorithm
–E-FEC—Standard ITU-T G.975.1 algorithm, which is a super FEC code
•Automatic laser shutdown: A safety mechanism used in the event of a fiber cut. The ALS procedure is supported on both client and trunk interfaces. On the client interface, ALS is compliant with ITU-T G.664 (6/99). On the data application and trunk interface, the switch on and off pulse duration is greater than 60 seconds. The on and off pulse duration is user-configurable.
•SONET/SDH Configurations: The cards can be provisioned in a linear configuration, BLSR/MS-SPRing, path protection/SNCP, or a regenerator. The cards can be used in the middle of BLSR/MS-SPRing or 1+1 spans when the cards are configured for transparent termination mode.
Client and Trunk Ports
The TXP_MR_10E card features a universal transponder 2 (UT2) 1550-nm tunable laser (C band) or a UT2 1580-nm tunable laser (L band) for the trunk port and a separately orderable ONS-XC-10G-S1 1310-nm laser XFP module for the client port. On its faceplate, the TXP_MR_10E_C and TXP_MR_10E_L cards contain two transmit and receive connector pairs, one for the trunk port and one for the client port. Each connector pair is labeled.
DWDM Trunk Interface
On the trunk side, the TXP_MR_10E_C and TXP_MR_10E_L cards provide a 10-Gbps STM-64/OC-192 interface. There are 80 tunable channels available in the 1550-nm C band or 82 tunable channels available in the 1580-nm L band on the 50-GHz ITU grid for the DWDM interface. The TXP_MR_10E_C and TXP_MR_10E_C cards provide 3R transponder functionality for this 10-Gbps trunk interface. Therefore, the card is suited for use in long-range amplified systems. The DWDM interface is compliant with ITU-T G.707, ITU-T G.709, and Telcordia GR-253-CORE standards.
The DWDM trunk port operates at a rate that is dependent on the input signal and the presence or absence of the ITU-T G.709 Digital Wrapper/FEC. The possible trunk rates are:
•OC192 (9.95328 Gbps)
•OTU2 (10.70923 Gbps)
•10GE (10.3125 Gbps) or 10GE into OTU2 (nonstandard 10.0957 Gbps)
•10G-FC (10.51875 Gbps) or 10G-FC into OTU2 (nonstandard 11.31764 Gbps)
The maximum system reach in filterless applications without the use of optical amplification or regenerators is nominally rated at 23 dB over C-SMF fiber. This rating is not a product specification, but is given for informational purposes. It is subject to change.
Client-to-Trunk Mapping
The TXP_MR_10E_C and TXP_MR_10E_L cards can perform ODU2-to-OCh mapping, which allows operators to provision data payloads in a standard way across 10-Gbps optical links.
Digital wrappers that define client side interfaces are called ODU2 entities in ITU-T G.709. Digital wrappers that define trunk side interfaces are called OCh in ITU-T G.709. ODU2 digital wrappers can include G-MPLS signaling extensions to ITU-T G.709 (such as LSP and G-PID values) to define client interfaces and payload protocols.
Wavelength Identification
The TXP_MR_10E_C card is tunable across 82 wavelengths in the C-band frequency plan, with channels on the ITU 50-GHz grid, as shown in Table 1.
The TXP_MR_10E_L card is tunable across 80 wavelengths in the L band frequency plan, with channels on the ITU 50-GHz grid, as shown in Table 2.

Install the TXP_MR_10E_C and TXP_MR_10E_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 TXP or MXP 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 a 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.
