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!

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 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.

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.

ONS 15454 LOS-O minor alarm problem

3 days ago, I got the LOS-O alarm. I have followed the instruct from troubleshooting guide but could not clear this alarm.

(In this firgure, dont care about side A, my trunk line is cut . The problem is on side B, it pops some minor alarm but the connection is still ok)
ALARM:
You can see that there are: SPANLEN-OUT-OF-RANGE and LOS-O. The problem is the power on line RX on OSC-CSM card is below the configured threshold, right? I have monitored the power and the value is -19.5 dbm.
Then I go to Provisioning --> WDM-ANS --> side B --> Rx --> Threshold.OSC LOS is imported as -23.5 dbm.
I also checked the span loss, the measured spanloss is 15.2 (resolution 1.5). It is between the Min exp span loss (15) and Max exp span loss (17).
So what is the problem, please help me to clear this alarm. Thank you very much.

You are right. the alarm is shown as the power is below the threshold.
If we have OSC LOS threshold set to -23.5 and the total Rx power is Rx power is about -23.5 (on the 40 km span) then we definitely below the threshold as we need to subtract the payload power from the total to get OSC.
Average loss on a fiber is 0.3dB per km, hence the expected loss on 40km would be around 12dB. I doubt the OS Tx power on the remote end is -11dBm (-23 + 12) so most likely that is the fiber/connector issue.
Swap Line Rx and Tx fibers on both switches on OSC-CSM card to verify if the problem follows the fiber or stay with the cards.

Alex.

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

ONS 15454 error message

Hi Expert,
I have a problem with ONS 15454 error message. My CTM server detected MINOR error message "Peer to Peer Slot Communication Failure". Affected object is SLOT-1 which is OPT_BST. The alarm ID is 200551. What caused this error appear and any workaround to solve this problem?. Your kind attention is much appreciated.

Although the following alarm is not identical to the one you identified, this seems to indicate the a peer "communication failure" is hardware related.
2.5.237 PEER-NORESPONSE
Default Severity: Major (MJ), Non-Service-Affecting (NSA)
Logical Object: EQPT
The switch agent raises a Peer Card Not Responding alarm if either traffic card in a protection group does not receive a response to the peer status request message. PEER-NORESPONSE is a software failure and occurs at the task level, as opposed to a communication failure, which is a hardware failure between peer cards.
Hope this 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.

ONS 15454 shows up as "unknown" after power outage

We had a power outage that took down a ONS 15454 in a remote facility. Upon restoring power and powering-up the unit, it shows up in CTC as grey with "Uknown2" as the name.
I had someone reseat the TCC card, but it still comes up as unknown.
Has anyone seen this? Any suggestions (the device is hours from me)

Try and restart CTC session and clear CTC cache
Can you ping the node
Check to see if the node is in the OSPF routing table
Can you access via CTC locally
Is your CTC terminal directly connected or does it go via a firewall
Probably resolved now how did you resolve it?

ONS 15454 Craft interface to a Cisco 2511 Terminal Server

Does anybody have pinout of wiring ONS 15454 craft interface to a Cisco 2511 terminal server? I tried many combinations but nothing seem to work.
2511 has octal cable with RJ-45 connector. I used an rj-45 coupler to connect a wire wrapped RJ-45 cable to craft interface.

ONS 15454 problem turning up OC12

Board.
I am trying to turn up an OC12 (non-concatenated) that is muxed from a OC48. The OC48 terminates on an ONS 15454 on both sides. From there we run SM fiber to Cisco 12000 series onto an SM OC12/SMT4 Line card on both sides too.
My settings for the ONS are as follows:
Type=STS
Size 12C
Dir = 2way
We see on one Cisco UP/DOWN, and on other Cisco Down/Down
Does any on this forum have any tips at all?

Which OC12 LC do you have on the 12000?
CHOC12/STS3-IR-SC
4OC12E/POS-IR-S
4OC12X/POS-I-SC-B
etc

ONS 15454 Version 8 Experience?

I'd like to know the experiences of anyone who has upgraded to SW version 8.0 on ONS 15454 SONET nodes. I'm trying to decide whether to use the tried-and-true 7.2.2 load or go for 8.0, which doesn't have any maintenance revs out yet. I have to do something to get off version 4.6.1 and 5.0.5 soon.
Thanks,
Dave

most that I log into are on 7.2.2. We have one of the largest 15454 networks in the US

ONS 15454 Chassis Document

Hello All,
I wanted to know if there is a document that will show how to put an ONS 15454 chassis together? What each TCC, SMR, WXC card means and used for? What the DS, OSC, LINE, COM, EXP ports used for? Etc.
If someone can point me in the right direction that would be great!
Thanks!

Well the product support pages show how to physically install y every componenet of the ONS equipment:
