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
/Dirk

  • 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.

  • 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.

  • Timing over an ONS 15454 SONET link.

    Hello,
         Are there any provisioning restrictions on passing timing over a SONET link on the ONS 15454. Here is the senario; I have an OC-48 provisioned over Slot 4, port 1-1 on an MRC-12 card. On the Line provisioning tab, I am unable to set the ProvideSync check box. I need to use the link to time a distant end node. The far link is RX the STU SSM. The local Node is set for external timing with BITS 1 and 2 active and inservice w/PRS. Is there something I am missing?
    TIA,
    Steve

    Steve,
    The OC48 port is always providing timing information to the attached device in the S1 byte of the Line Overhead.
    The ProvidesSync box is not an indication of whether the port is providing timing.  Rather it is an indication that that port is being used as a timing source  (Line Timing).  If you go to Provisioning->Timing and select that slot/port as a Timing Reference the ProvidesSync box will be checked.
    I will upload a Word document with screen shots. It should help clear things up.

  • 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.

  • ONS 15454 SDH with 2 ML cards connected to the same RPR

    I was wondering if I could connect 2 ML cards installed in the same ONS 15454 to the same RPR ring. Thanks!

    Bob,
    If you are wanting to tie the ML100 and the ML1000 into the same RPR Ring, then you have do do it with the POS interfaces.
    For Example:
    ML 100 POS 0   - North  Microwave
    ML 100 POS 1   - connect RPR to ML 1000 POS 0
    ML 1000 POS 1 - South Microwave
    North Microwave connects RPR to South Microwave
    This creates a single Loop or Ring
    It sounds like you are using your ML1000 as a Spur to another location.  In order to create an RPR ring, you must have the cards physically connected to each other in a continuous ring.

  • 1:1 Card Protection ONS 15454

    Hi All,
    I am trying to understand the reason why the protect card/port shouldn't be in OOS(Out of service) to avoid any traffic loss even though the protect card is not switching traffic in ONS 15454 as stated below
    "When a protection switch moves traffic from the DS3-12 working/active card to the DS3-12 protect/standby card, ports
    on the new active/standby card cannot be taken out of service as long as traffic is switched. Lost traffic can result
    when a port is taken out of service even if the DS3-12 standby card no longer carries traffic."
    Thanking You

  • 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.

  • 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 ML Card Question

    I have an ONS 15454 with an ML-100

    Thanks,

    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.

  • 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 MRC 2.5G4

    Hi All,
    We are trying to install the optical multirate card (MRC 2.5Gig) on ONS 15454 and found the card comming up on standby state instead of active. The version running on the sonet box is 8.5.0 ...The MRC card port 1 is installed with the OC3 SFP's but cable not attached.
    Any help would be appreciated .
    Regards
    Anantha Subramanian Natarajan

    Hi, this is normal. Just go on and enable a SFP, called pluggable port module (PPM). After the first SFP is enabled, the state of the MRC card will change to working.

  • ONS 15454 Load Testing

    I would like to perform a load testing on the ONS MSTP 15454, maybe back-back. Has anyone done anything similar for the Cisco ONS's? Any comment will be helpful.

    test the optical modules
    for testing optical modules you can have simple BERT which can show you that link is free of error or within limits. There is no load testing in SONET/DWDM as these equipemts just take whatever received and send it they are not like router or switches where there are routing table lookup, policing, ACl etc.
    But things changed when you map Ethernet i.e data traffic to SONET/DWDM both are working at differnt line rate though both are 10G. So need a network tester who can test you Ethernet over SONET/DWDM traffic. These network tesetr are pretty costly so either you can rent or ask your service provider/equipment provider to test for you.
