ONS 15454 design question

I have an ONS 15454 with 2 OC192 circuits that terminate into it. One goes to a downstream ONS and another to the upstream.
I need to extend the existing ring to 2 more ONS devices, but I am not sure if it is going to work the way I want it to.
Right now, each VTS24 circuit on the OC192 is associated with a POS interface on the ML1000 cards. So POS1 goes upstream, POS0 downstream (unprotected). The ML1000 is int turn trunked to a 3750 L3 switch that has the bridge groups and layer 3 addressing assigned. This is Ring0
I need to extend this ring, so obviously I will need 2 additional OC192 cards, but do these new circuits need to be associated with new POS interfaces? In other words, will I need 2 additional ML1000 cards, and if so, how would I trunk to the switch? Am I going to get into some loopy topology here?
I am new to this system, so any advice would be great.

Hi Colin,
so you want to add two more ONS devices in an existing ring.
if you can provide a topology it will be helpful,
if you just want to add two more ONS in existing ring, it will no cause any issues,
we just have to take care of circuits and need to build them from TL1 in these new nodes.
but please send topology to get an clear view.

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.

About the DWDM 15454 optical ring design questions.

1 Question
We have 3 ONS 15454 in A,B,C each place. The connection between different locations is a pair of single mode fiber. The topology is A>B>C>A. The A is main datacenter.
We want to make a redundancy design based on ROADM. The normal transmission is A to B to C to A. For example, when the problem occurred between C and A, like CxA. We want to change the data transfer direction to C>B>A.
How could I do that through the 15454 configuration software CTC? Which protocol should I use? I am newbie in the optical network. Please give me an easy grasping answer. (Please don't change the topology because we not only have A,B,C we also have other 3 locations to join in the optical ring. I just want to use A B C to make the question easy to be answered)
2 Question
The 15454-GE-XPE card mode made me a little confused. Our each location have 2 15216 MUX/DEMUX patch Panel Odd. One for MUX to next location. One for DEMUX from last location. Does that mean I don’t need to open the GE-XPE cards’ MXP mode?
The reason I want to use L2 mode is that we have 2 GE-XPE cards for each location for different department function. The connection is 1st SFP port from GE-XPE to 6509 supervisor engine 2T active. 11th SFP port connects to 6509 supervisor 2T standby. The 11th SFP will have no data until the
active supervisor 2T changed to down. I am worried about if I open the MXP mode for GE-XPE. The 21th XPF gets data from 15216 DEMUX panel and transfers it to 6509 engine 2T through 1st SFP. But 6509 can’t transfer the data back to 22th XPF through the 11th SFP on the GE-XPE. Because the 11th SFP connection is on standby engine 2T.
The question is what is the best way to make the right data flow direction from 15216 DEMUX through 6509 and back to 15216 MUX panel.
Thank you for the reading and help!
I will do my best to reply every feedback.:)

about Question-1
there are two ways to achieve your requirements.
use PSM card or second way is to use WSON.
PSM card is easy to install and it will cost less.
for WSON solution, your wavelength will switch automatically on fiber cut, but for this you have to make two nodes omni-directional that is source and drop nodes for that wavelength which seeks proteciton.
to make omnidirectional you need extra piece of hardware.
if your node has SMR2 cards, than you need one more SMR2 to make it omni-directional.
if its WXC than you need one more WXC, plus PRE and BST amplifiers.
so i think, just go for PSM cards :-)
about Question-2
The main question is if I open the 10GE MXP mode on the 15454-GE-XPE card, the port 1~10 can’t do any communication with port 11~20 unless I connect them with a SFP switch, is it right?
yes this is correct.
Another problem is I confused about the muxponder mode GE-XPE and the 15216 MUX/DEMUX Patch Panel. Are they doing the same job MUX/DEMUX?
no there is difference.
there are three modes on GE_XPE card.
10GE MXP mode:
if you select this mode.
than it will multiplex all the traffic coming on port 1 to port 10 and trasnmit it through port 21-1.
and traffic received on ports 11 to ports 20 is multiplexed and transmit it through port 22-1.
in other words, all traffic coming on port-1 to port-10 is encapsulated over a OTN/SONET/SDH and transmitted via port 21. same for port 11 to port 20.
20GE MXP mode:
all the traffic recevied over por-1 to port-20 is multiplexed and transmitted through port 21, in this port port 22 is not used.
Layer-2 mode.
you have to proviion QinQ and SVLANS to pass traffic.
15216 MUX/DMUX are entirely different, they are used to multiplex and de-multiplex wavelength.
so if we have 5 GE_XPE cards on each node A and node B.
and you want to connected each card with each other, suppose port 21 of each card on each node is connected with each other.
than you need 10 fibers to connect them, one for each Tx----------Rx.
so instead of doing this, people use MUX/DMUX, in your case it is 15216 MUX/DMUX
so trunk port 21 of each 5 cards will be connected with these MUX/DMUX and than the signal is transposrted is this way.
please go through this picture.

ONS 15454 Back Plane DS1 Cable Question...

Do the DS1 connectors on the back plane of the ONS 15454 mate with screw down AMP Champ connectors or with Bail Lock AMP Champ connectors? The documentation seems to be ambiguous. The part number listed for the connector is a Bail Lock type connector, but the drawings and the last paragraph in section 1.11.2 of the Hardware Installation document suggest it is a Screw Down connector.

Cisco ONS 15454 SONET MSPP

I am doing a school research project in which I am setting up an OC-192 ring for a company (contract work through AT&T). I have chosen to use the Cisco ONS 15454 SONET MSPP as my platform. The company currently has locations in Chicago and Philadelphia and connects them through an OC-12C ATM connection and they are looking to add 2 gigabit ethernet connections.
My question is what cards and parts will I need for the Cisco ONS 15454 SONET MSPP, and how much will everything cost? I have been searching the internet for components and prices and I have found it extremely difficult to find any information. Any help or tips anyone can offer would be greatly appreciated.

Nick,
You can find the HW specifications for various ethernet cards for the 15454 at the following location.
http://www.cisco.com/en/US/docs/optical/15000r9_1/15454/sdh/reference/guide/454e91_ethernetcards.htmlhttp://www.cisco.com/en/US/docs/optical/15000r9_1/15454/sdh/reference/guide/454e91_refer.html
To make sense of it all, you need to contact a Cisco sales/account represetative to help you analyze your needs, design your network and put together a price list for the appropriate cards.
If you are interested, I can get someone from the sales/account team to contact you. Please contact me directly with your contact information and geographic location so I can find the appropriate sales/account to help you. Please do not post your personal information directly to the forum.

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.

Upgrade ONS 15454 M12 TCC2P from 9.4.03 to 10.0.11

Hello,
quick question.
I have in my lab one M12 subrack with only-one TCC2P card and I try to prepare software upgrade in customer network.
I read all procedures at: http://www.cisco.com/c/en/us/td/docs/optical/15000r/upgrade/guide/b-454a10-0-1-upgrade.html
My troubles started at point where I can select node where the software must be downloaded. The window is empty.
Target version is "ons15454.DWDM.Lite.K9.R10011.pkg".
Any idea?
Thanks
kvapa

Hi Emyrsonn,
I hope this ONS 15454 upgrade tool can help you answering all your questions
http://www.cisco.com/web/techdoc/optical/15000r/upgrade/guide/ons-upgrade.html
It seems like you should be able to directly upgrade from 9.1.x to 9.2.2.
Please let me know if you have any comments on that.
Hope it helps!

Cisco ONS 15454 SDH

Hi,
i have 3 sites connecting together with SDH 15454 site A-B with STM-1 and from site B-C STM-16,i want to Aggregated hand-off E1's from Site A-C so site B will be trasparet site for this link.
to be source of link on site A and Drop on site C.
any help to achive this.
there is already cricte between site B-C.

You will need to verify that the cross-connect card in the ONS 15454 (sites B & C) have VC-12 grooming capabilities (XC-VXL and CX-VXC will support VC-12 grooming).
The ONS is designed to groom lower rate signals to higher rate speed lines. Thus, you should be able to aggregate the E1s from the ISPs STM1 with the E1s from Site B and drop them at Site C.
You will need to add an STM1 card(s) to Site B. Your ISP will need to provide the mapping structure of the STM1, so you can understand where the VC-12s, which contain the E1s, are located in the payload. You will then create circuits to map each E1 (the incoming VC-12s within VC3/VC4) from you ISPs STM1 at Site B, to the appropriate VC-12 on the outgoing STM16 line heading toward Site C. At Site C, you will need to map the VC-12s on the STM16 line to the appropriate port on an E1 line card.
I hope this helps. Otherwise, you will need to have someone locally assist you in the explanation.

CTC shows a card that isn`t instaled on the ONS 15454

On the ONS 15454 I have a TCC2P card on slot 11, slot 7 is empty, but when i access the CTC i see the card on slot 11 in white, and i also see a TCC2P card on slot 7 in light blue, so how can i stop ctc showing the card on slot 7

you can't do that, thats how the system is designed.

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

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.

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.
Rgds
Helme

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.
