DWDM: ONS 15454 MSTP M6 TNCE and TSCE

In a ONS 15454 MSTP M6 chassy (DWDM) both Transport Node Controller (TNC) and Transport Shelf Controller (TSC) cards can be installed in slot 1and 8 to perform system initialization, provisioning, alarm reporting, maintenance and diagnostics.
Can someboby clarify the following:
1) What is the difference between a TNCE and TSCE Card? (The only difference I found is that TNCE can be configured with one or two SFP ports to provide the OSC termination while TSCE not. Are there other differences? )
2) Is it possible to intall in the same 15454 M6 chassy one TNCE and one TSCE card?
3) Are there any circumstance under which is mandatory to install the TNCE card?
4) Is there any suggested cisco documentation or book explaining it in details?
Thanks

You can use an Mutiple M6 chassis in one node in a Multi Shelf configuration the TNC cards are designed to go in the the Primary or 1st node and you can use the TSC cards in the other nodes and connect them together using the MSM ports on the ECU cards.
Yes your are correct regarding the OSC ports are not enabled on the TSC cards. The TSC cards are a lower cost then the TNC cards as they are only for use with a subtended shelf.
2) Is it possible to intall in the same 15454 M6 chassis one TNCE and one TSCE card?
I dont believe so however you can install just a single TNCE card in a chassis if you don't require redundancy
3) Are there any circumstance under which is mandatory to install the TNCE card?
I believe a TNCE card is required for any node in a standalone configuration or in a Multi Shelf configuration.

Dual Ring Capabilty for ONS 15454 MSTP

Hi!
I am designing a MPLS over DWDM network which consist of one core DWDM ring and several regional DWDM ring using ONS 15454 MSTP. I would like to connect the regional ring to the core ring via P router in this case Cisco 12406GSR. My major concern now is to reduce the number of boxes especially on the DWDM part. Can an ONS box connect to 2 DWDM ring, regional and core directly without using a router in the middle. Apreciate your expert opinions. Thanks.

Core DWDM ring and Regional DWDM ring are built using ROADM cards for full add/drop flexibility. Wavelengths can be engineered to pass between rings by physically patching at the wavelength level. By using the Mesh/Multiring Upgrade card (available today - see data sheet below) you can prepare the network for Degree-N capability, allowing multiple rings to be connected via a single point with dynamic wavelength provisioning across the rings.

ONS 15454 MSTP Client Connection Options

Hi!
Have questions regarding client connection options to ONS 15454 MSTP. FYI, I have experience on ONS 15540 ESPx and I usually connect client to the ONS using transponder like this
ONS 15540 ESPx
Client<->transponder<->OADM<->OADM<->transponder<->client
I am new to ONS 15454 MSTP and from the reference manual I understand that the it can be configured as hub, passive oadm, anti ase etc. My questions is how does the client get connected to each of this configurations
For example, for a passive or amplified nodes the client connections would be like this
ONS 15454 MSTP
client<->transponder<->OADM<->OA<->OA<->OADM<->transponder<->client
What about hub nodes where mux/demux card are used, where does the client connect,I do understand that these cards have to be used in pairs.
As always,appreciate your expert opinions and if you can point me to a web link that would be even better. Many Thanks.

In both cases, the client (assuming it has a non-ITU output) will connect via a transponder or muxponder card. This takes the client signal and converts (with multiplexing in the muxponder case) the client signal into an ITU wavelength.
On the MSTP, the ITU port on the transponder/muxponder is then physically patched into the appropriate port on either ROADM, OADM or Mux/Demux cards.
To directly answer your question, on a hub node equipped with Mux/Demux cards, the Tx from the Transponder is connected to the Mux card, and the Rx connected to the Demux. Likewise, at the node where the wavelength is dropped (eg at an OADM site), there will be an equivalent transpoder connected to the OADM module (Tx and Rx at wavelength xyz).
The transponders/muxponders may be in the same shelf, separate shelves, or you may use a direct ITU connection from devices such as a DWDM GBIC, an SDH DWDM card or 10GE XENPAK from Catalyst 6500.
As long as you have designed the network to take the appropriate interface types into account, you should be fine.

Latency in MXP on ONS 15454 MSTP

Hi!
Have a question concerning latency in MXP for ONS 15454 MSTP. How do you define and measure it? I mean in for MXP you basically mux many client signals in to one lambda. Since this muxing requires O-E-O process there got to be some latency? Or is the values to small that it become neglible and we dont have to worry about it. My customer is asking me this and I cant come up with a definitive answer. To me there's practically none, it work at optical level, as to determine latency it is enough just from looking and end-to-end ping result on client side. Apreciate your expert advice.

You are correct, there's practically none. To determine latency it is enough just from looking and end-to-end ping result on client side

ONS 15454 MSTP & SNMP for MRTG

I can't find regular oid for optical power and span loss. I need them for mrtg statistics.

I have not found an SNMP value for span loss but you may be able to calculate it as the difference between the transmit power and rceive power across a span. You may want to look at cOpticalParameterValue 1.3.6.1.4.1.3607.2.30.1.1.1.3 and cMsDwdmIfTransportPower 1.3.6.1.4.1.3607.2.40.1.2.1.3 as the base OIDs for ports on OPT-BST, OPT-PRE, and MXPP cards. So far for me the values are matching up with those presented in CTC. I'm running sw version 8.5 so things may be different if you are running a significantly different version. To see RX power I add on to the base OID... cOpticalParameterValue.%inst%.1.1 . It is similar for TX and laser bias power etc. TX power = cOpticalParameterValue.%inst%.2.1 . Bias= cOpticalParameterValue.%inst%.2.5 .
I hope this helps!

Mixing SONET/DWDM Cards in a ONS 15454

All,
To my understanding, there are some limitations to mixing SONET line cards with DWDM line cards in the same ONS 15454 chassis. I believe one of the limitations had to do with the line card placement versus a OSC-M and OSC. I can't remember the draw backs of doing the above, but there was some negative.
Are there any more draw backs, limitaitons or gotchas?
Also, generally, the optical engineers I spoke to recommended never mixing the cards and keeping them in seperate chassis.

Hello Jason,
Mixing SONET/SDH and DWDM functions in the same chassis is a supported configuration on the ONS 15454 platform.
As was stated in the other posts, you would have to install the SONET/SDH crossconnect cards in the chassis in order to have the HO/LO functionality.
You are right, that there is an impact on the card placement in the chassis, however you can force the planning tool (Cisco TransportPlanner) to leave the required slots for the XC cards empty when designing the DWDM network.
The model described so far is what is commonly referred to as a "hybrid" node.
There is one other element in the toolchest however - The ADM-on-a-Blade (see http://www.cisco.com/en/US/partner/prod/collateral/optical/ps5724/ps2006/ps5320/product_data_sheet0900aecd805f0e80.html). This network element is an integrated part of the DWDM personality of the ONS 15454 and provides SONET/SDH switching and client ports on the blade. Please note however, that this network element provides only a high-order crossconnect.
It is generally true that one would usually keep SONET/SDH network elements in separate chassis. However, from a network management perspective these separate chassis can form a single node.
Hope that helps

ONS 15454 and AC/DC Converter for 220V

I am looking for a AC/DC converter for a ONS15454 for a 220V input.
The ONS 15454 datasheet indicate input current 22A maximum.
The Cisco AC/DC Power Solution datasheet indicate for ONS 15454 a medium solution.
And the same datasheet indicate the small solution is up to 32A for 220V.
Then, can I use the small configuration for ONS at 220V?
Anyone know that? Can you help me with that?
Graciela

What is the hardware configuration of your 15454 including chassis, fan and by slot?
Using the hardware config, you can calcualte the expected amperage.
http://www.cisco.com/en/US/partner/products/hw/optical/ps2006/products_tech_note09186a0080094ae4.shtml
The general power requirement of 22A provides for any possible configuration. Actual configurations may be less. I have some 454s using as little as 9A in the lab.

Ethernet over OC-3 between a E100T-12 (ONS 15454) and a remote device

What CISCO device will accept an OC-3 (non-ATM) interface and establish an Ethernet connection with a E100T-12 card in a CISCO ONS 15454?

You could map an Ethernet circuit from an ONS 15327 over an OC3 and terminate it on E100T-12 on the 15454. Hope that helps.

ONS-15454 V8.5 and SNMP V2c

Can someone tell me if the ONS-15454 support INFORM Traps?
I'm trying to get INFORM Traps working with my NMS, but I don't think it's working. Either I don't have it configured correctly or its supported on the ONS.
Many Thanks

You are correct. INFORM Requests are different from TRAPS. Both are sent from the monitored device to the SNMP Manager. Both advise the SNMP Manager of an event that has occurred. The difference is the INFORM Request requires a response from the SNMP Manager while a TRAP does not. The INFORM Request allows the monitored device to know that the SNMP Manager has received his message.
Now to the ONS... it supports TRAPS, but not INFORM Requests.

ONS 15454 MSPP Recommendation

Currently Being Moderated
ONS 15454 Recommendations
Hello Guys,
Just looking for some recommendations / best practices from experienced ONS 15454 engineers for the following questions.
Scenario:
There are 2 sites located 130 km away from one to the other and we want to provide a wan connectivity via ONS 15454.
Questions:
1. The ethernet / DWDM modules preferred
2. The typical wave length will be used -- 1550 or 1310?
3. What are the speeds supported on the modules?
4. What should be the recommended max losses / power budget for 130 km for Cisco ONS to work properly?
5. Any specific recommendations.
Thanks & Regards
Jay

1. The ethernet / DWDM modules preferred
GE_XPE, 10GE_XPE, OTU2_XP, ML cards,
CE-Series 10-Port Multirate Ethernet Card, 10DME, MXP, 10x10 there are lot of cards depends on your requirement, line rates coming from WAN device, types of module present on WAN side.
2. The typical wave length will be used -- 1550 or 1310?
depends if you looking for a SDH/SONET solution, will say 1550, if DWDM than it will be composite siganal with MUX/DMUX.
3. What are the speeds supported on the modules?
10mbps, 100Mbps, 1000Mbps, 1Gig, 10Gig, 40gig and 100Gig depends on your requirement :-)
4. What should be the recommended max losses / power budget for 130 km for Cisco ONS to work properly?
around 35dB to 39dB of span loss, looks you need amplification.
5. Any specific recommendations.
we need to discuss your requiremnets, there are lot of sloution available.

Native fibre channel using SL cards on ONS 15454.

Greetings,
I normally hang out in the Storage Networking forum but I thought this would be a good spot to ask a question.
We current have a dark fibre connection between our sites and have issues with our Brocade switches (yeah, they should be MDS) with buffer zero problems. We want to add more bandwidth for our ISL's and we have a couple of ONS 15454's hanging around in racks in our datacentres.. I have been looking at the SL cards for the 15454 and would like to know if anyone has had success with them. I need to do synchronous True Copy between the storage at both sites for a new project. We are using async now but that wont be good enough.
Any comments would be welcome.
Stephen

Stephen,
I don't have any SL cards in production, but do have ML cards, and a myriad of TXP/MXP's on MSTP platforms.
I can tell you, the ML card does a decent job with distance extension is turned on. I have a few STS-24's extended across 400-500KM span lengths for TAPE drives across ML cards and see consistently high throughput.
Measured latency across a 70km span was about 600us with an ML card. Pretty close to an equivalent circuit built across a Muxponder.
I would venture to say, the only concern that you may have with synchronous replication is the latency.
Regards,
Tom.

10G Bigger Pipe on ONS 15454

I have two STM4 SDH capacities and one STM16 SDH spanning two cities over different service providers. See Attachment, I have two Cisco ONS 15454 in two cities, one of the ONS is connected to a GSR router serving as core router while the second ONS is connected to a 7609-S serving as MPLS-PE router, their is DOT1q tagging transparently carried over the SDH circuits between the two routers. I want to make these capacities one big Ethernet pipe (10G) at both ends, this fat pipe should be able to carry multiple VLANs between the attached routers at both ends. Is this achievable? if yes what kind of Ethernet cards do I require on ONS and the routers? Any supporting document will be highly appreciated.

"but I am not sure if Cisco produce a 10G ethernet cards for ONS 15454?"
cisco also have 10G Ethernet card but it can go over DWDM box not STM 16 & STM 4.
I am not sure what ECi and Huwai are offering but i am sure of one thing that even if they give you 10G Ethernet card but you CANNOT map that single Ethernet card to your 3 STM interfaces (1 STM 16 & 2 STM 4). As far as i know you can map one ethernet port to one SDH port (either 1 STM 16 or 1 STM 4).
Before believing ECI & Huwaei discuss that solution with some people, as I know one thing there can be lot of strings later on.
They say totally different thing before but once you buy that then you get to know the real features. You will have the feature but with lot of if & but.
What you can do is if that makes sense in your case, take 10 1Gig (Total 10G) ethernet card then you can map 3 ethernet ports to 3 STM interfaces you have.
Whats is the max speed your provider can give you? If they give you 10G SDH then see if you can get 10G POS card for your routers.
You can think of DWDM solution, this way you can take 10G direct over a wavelngth and lot many later. What is the distance between your 2 ONS?

6509 to ons 15454 showing not connect.

Were running into a problem moving from an oc48 to oc192. In our web enviornment we have a Front-end switch and a Back-end switch in two data centers that are 10 miles apart. Were running a "gigaman" betweent the two. On both ends we have cs6509's and were patched into the Gbic interface on the sup2's. This fiber is ran to are lec's ons 15454 which I have no visibility into. We are unable to get a connection on the 6509's. Were doing basic layer 2 trunking between the switches. Sbc tested from the fiber on the switch to a loop on the other switch and was able to test clean. This worked on the oc-48 but are switches were not connected to a cisco ons. Any suggestions would be apperciated. You can also email me at [email protected] or AIM jjt8572.

Have you checked that you have matched the physical media framing - e.g., LAN PHY needs to speak to LAN PHY (or WAN PHY to WAN PHY). Typically the ONS 15454 would be looking for a SONET frames (WAN PHY) while a Cisco 6509 would be sending 10 Gigabit Ethernet LAN frames (LAN PHY). That is, unless you specifically choose an interface for your 6509 such as the XENPAK-10GB-LW (10GBASE-LW XENPAK Module with WAN PHY for SMF). From that product's data sheet: "The Cisco 10GBASE-LW Module supports a link length of 10 kilometers on standard single-mode fiber (SMF) (G.652).
WAN-PHY is intended to allow the transport of 10 Gigabit Ethernet over a traditional SONET/SDH infrastructure. The purpose of WAN-PHY is to render 10 Gigabit Ethernet compatible with SONET STS-192c format and data rate, as defined by ANSI, as well as the SDH VC-4-64c container specified by ITU."
One can also use Cisco ONS transponder cards that will wrap LAN PHY framing in something like G.709 encapsulation to allow it to be transported through a DWDM network.

ONS 15454 issue

Hello! I'm new in this network infrastructure and i have to create a fiber ring between 3 ons 15454 dwdm but i managed only to make an osc between them . On every platform i have an transponder 2.5Gbps. My problem is that i can't create some provisionable patchcord and also some ochcc,only ochnc and when i activate the transponders my rx com line on every opt-bst show me an "incoming payload signal absent" error. Can anyone give me some advice or some steps to follow in creating this ring ? Hope i've been clear and sorry my poor english. Thank's a lot!
