DALLAS -- NFOEC -- Cisco Systems Inc. (Nasdaq: CSCO) announced Monday a souped-up multiservice switch that combines the function of several Sonet optical add/drop multiplexers (ADMs) and a broadband digital crossconnect.

The switch is designed to sit in larger metropolitan networks, where it aggregates, grooms, and switches traffic from the ADMs sitting on the metro rings. Carriers now perform those functions by combining several ADMs for transport and aggregation and using a broadband digital crossconnect for switching.

One appeal to a box such as the ONS 15600 is that it eliminates several boxes and frees up space in carrier central offices. But to some, it may be taking on too many tasks at once. "It's very God-box-like," says Mark Lutkowitz, VP of Communications Industry Researchers Inc. "It should be more simple. The Cerent box was like that."

Interestingly, one network element the ONS 15600 could replace would be Cisco's ONS 15454 ADM, the first and arguably most famous product in its optical networking portfolio. Cisco says it's not worried about losing business to its new product; the company says any displaced ONS 15454s could always be redeployed in a carrier's other metro rings.

That said, the ONS 15600 is a dense metro switch. The box has a 320-Gbit/s switch fabric and handles 384 OC48 (2.5 Gbit/s) connections per rack. With that kind of density, it could compete with Ciena Corp.'s (Nasdaq: CIEN) CoreDirector switch, the current market leader in long-haul applications, which is sometimes used in the metro core.

Cisco, which often innovates by acquisition, says this particular product was developed 100 percent by Cisco hands. Of course, some of the Cisco hands that developed the hardware came from Cisco when it acquired Monterey Networks, a failed core optical switch maker. Many of the other hands came to Cisco from Cerent, where a good bit of the ONS 15600 software code was initially authored.

The product was developed in Cisco's Richardson, Texas, facility in about 18 months time, according to David Lively, Cisco's senior manager for optical strategy. It is expected to ship in the fourth quarter of this year and will be done with the Osmine certification process by March 2003, he says.

Two customers -- U.S. Signal, a Michigan-based competitive local exchange carrier, and Looking Glass Networks, an Illinois-based wholesale carrier -- are currently putting the ONS 15600 through its paces in network trials, Cisco says.

"I think they've hit a sweet spot in the industry," says Peter Evans, CEO of Optovation. Evans says the box could provide a huge boon to large service providers "if it can do everything Cisco's says it can do."

The new Cisco switch may help the company land more carrier sales as it adds yet another piece to a growing optical networking portfolio. However, the ONS 15600 isn't for everyone. Lively says there are "probably less than 100" carriers in the U.S. that have metro networks large enough to require such a switch.

Do you serious think Europeans talk anything other than English?

re: Cisco Launches Metro Switch
First of all Cisco has not published any performance numbers. It cannot be taken for granted that ONs 15530 can function suceesfully and flawlessly in a large metro environment. The recovery feature of the switch is not clear. The switch does not address multi-layer recovery. The worst case recovery is also not covered by the switch. The time of recovery in various failed scenarios is not addressed. In view of these and more facts not so far examined may hamper the deployment of switch in the carriers' environment.

It is al;so not clear what kind of provisioning function does the switch provide. The management of the switch is also not clear. If the management and provisioning functions cannot be integrated with the OSS's of public carrier, the use of switch is limited to only Cisco created networks.

Cisco has kept the pricing structure of the swich a secret. Since there are many metro switches in the market place, the fairness and rationale of pricing structure cannot be evaluated. The non-disclosure of prices can prevent further sales of the switch barring two very very small carriers.

Since switch 15530 requires DWDM instead of cheaper CWDM, the cost metro ring with Switch 15530 will become prohibitive.

It is also not clear how mant wavelengths Cico can multiples. Lucent, for example, can multiplex over 128 wavelengths per fiber. It is not clear if Cisco can do the same thing.

It is also not clear: what kind of optical signaling does Cisco provide? If standards have not been followed, it could affect the interoperability of equipment from other vendors.

It is also not clear how Cisco will address the scalability issues. To compete on a fair basis, Cisco should provide full verifiable disclosures.

Ummm...no...."Manhattan" was the 15232 as reported by Light Reading (http://www.lightreading.com/do... and the 15600 is called CXC. Get your facts straight before spouting off incorrect statements.

Don't have it unfortunately - just made some notes at NFOEC. Was pretty slick, though.

It will be interesting to see whether the RBOCs prefer learning a new language (German, French, or Finnish) to dealing with CSCO as the other North American vendors are systematically acquired.

BTW, who has the cash for this type of equipment these days?

I liked this quote 'The product was developed in Cisco's Richardson, Texas, facility in about 18 months time'

Should that read 'The product 'will be' developed in Cisco's Richardson, Texas, facility in about 18 months time'??? ;-)

Seriously though, this is a new box that is therefore smaller, higher capacity etc etc than offerings that have been around for a while.

Only one problem though - it's made by Cisco and all the Telcos hate them. They only deal with them on data because they perceive little choice - and that ain't the case for this kind of box.

In these days of tight capex I can see them staying with (and I didn't expect to say this, even a couple of months ago) Marconi - at least in Europe

Yes and RBOCs just love buying equipment from a cash-strapped startup, right? :-)

I bet Polaris isn't even sure it will be around to service their equipment in the field, if it makes it out there.... :-(

Looking at the Polaris switch which was also announced, it is way ahead of Cisco's in terms of new gen metro functionality. A TDM STS-1 only switch is going to have a tough selling time uness they give it away.

re: Cisco Launches Metro Switch

Wile, checked with the RBOCs lately re: hating CSCO? Let me give you 2 reasons that may NOT be so true anymore.

1/ CSCO may be the only man left standing....
2/ CSCO owns the enterprise customers, one of the last remaining revenue streams left.

Nuf said?
I think so.
/gd.

before, you said....

Yeah, but will it matter? CSCO is HATED by the RBOCs.

Still you have to applaud the fact that CSCO finally got something going and developed/delivered with internal engineering resources. Hardly home grown, looks more like the Frankenstein of metro God boxes, but it's a start.

A CSP's digital transformation involves so much more than technology. Crucial – and often most challenging – is the cultural transformation that goes along with it. As Sigma's Chief Technology Officer, Catherine Michel has extensive experience with technology as she leads the company's entire product portfolio and strategy. But she's also no stranger to merging technology and culture, having taken a company — Tribold — from inception to acquisition (by Sigma in 2013), and she continues to advise service providers on how to drive their own transformations. This impressive female leader and vocal advocate for other women in the industry will join Women in Comms for a live radio show to discuss all things digital transformation, including the cultural transformation that goes along with it.
