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.

  • 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.

  • 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 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.

  • 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!

  • 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?

    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.

  • 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?

  • 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.

  • 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.

  • 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.

  • BITS Out question on an ONS-15454

    I have a user that has a two node 15310CL network that is not optically connected to my ONS network. He needs a PRS level timing source for his network, but there is no external timing source available to him in that building. Can I program the ONS15454 BITS-1 out to provide the external source to his network? My 15454 is configured for LINE side timing.
    If this is possible, what would be the Cable pinout be between the 310CL and the 454?
    Thanks for any help.
    Steve

    Steve,
    The 15454 can provide a BITS-OUT to the 15310 via the BITS-OUT wire-wrap pins on the back of the15454 Chassis.
    The 15310 CL has an RJ-45 connector for the BITS Input with Pin 6 (-) and Pin 3 (+).  Here is a link to the user documentation that covers the pinout for the 15310 CL:
    http://www.cisco.com/en/US/docs/optical/15000r9_0/15310/sonet/procedure/guide/310a90_dlp0.html#wpxref12757
    And Here's the link for the 15454 Pins:
    http://www.cisco.com/en/US/docs/optical/15000r9_0/15454/sonet/procedure/guide/454a90_dlp0.html#wpxref12757
    Tip = (+)
    Ring = (-)
    To connect between the two, conect Tip(+) to Tip(+) and Ring(-) to Ring(-)
    You will then need to enable the BITS-IN on the 15310 as the Timing source

    And the BITS-OUT on the 15454:
    http://www.cisco.com/en/US/docs/optical/15000r9_0/15454/sonet/procedure/guide/454a90_dlp0.html#wpxref98779
    BITS-1 Out/BITS-2 Out—Define the timing references for equipment wired to the BITS Out pins on the backplane. BITS-1 Out and BITS-2 Out are enabled when BITS-1 and BITS-2 facilities are put in service. If Timing Mode is set to External, choose the OC-N card used to set the timing. If Timing Mode is set to Line, you can choose an OC-N card or choose NE Reference to have the BITS-1 Out and/or BITS-2 Out follow the same timing references as the NE.

  • CCM 4.1(3)sr3a different ring tone for different line

    Hi there,
    I've got a dual line 7941 phone and would like to configure different ring tone for each of the lines. eg. I've got ext 100 and 101 on my phone. i would like the phone to ring differently when a call comes into 100 and 101 so i can know just by the ring tone which number has been called.
    Can anybody help?
    Cheers,
    Jesminder

    Jesminder,
    Unfortunately ring tones are configured at a phone level. In order to do this you need to go to the phone, push the settings button, select ring type. From there you will get a menu. Line 1 of the menu is the default ring. Line 2 and on corresponding to your line numbers in order. So if you want CallManager line 2 to be a different ring tone then you will select line 3 from the ring type menu, it should have the extension number next to it.
    There also might be a way to set it via the web interface. You would want to post in the Ip Communications - Ip Phone services for end users forum.
    Please rate any helpful posts
    Thanks

  • 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.

  • 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.
