re: Nortel Expands Metro SDH Line From my view, the MSPP definition came with the ability to support more that PDH and SDH services, and the "any slot any service" mantra from vendors such as Fibrelane and Chromatis.

Lucent seems to be doing some good stuff with the Metropolis ADM and DMX - hardly 10 year old boxes. Actually, they've been doing Ethernet over SDH for about 3 years now on their Wavestar platforms. This cocktail of GFP, LCAS and VC seems to be a winner. It seems to be getting some following - ECI/Lightscape are backing this too. I wonder how soon til Marconi and Nortel change tack and become the fast follower?

re: Nortel Expands Metro SDH Line Alcatel owns more of this market than they are given credit for....

Alcatel Delivered More than 30,000 New-Generation SDH Systems to 135 Operators Worldwide in 2001, Primarily in Metro Networks

re: Nortel Expands Metro SDH Line Mr Light articulated :
The manufacturers saying so many thousands is interesting but has limited value if they are adding the numbers for different maximum rate SDH boxes together.


-> Good post: I also can't see where these deployment numbers have come from. I guess the problem is What is an MSPP ?" The term originally was coined by Cisco to differentiate its' SONET multiservice (SONET/WDM/GigE) product from standard ADMs, and so the question is where is the dividing line between MSPP/NG-SDH and old-gen SDH.
For Alcaltel, I see they have an MSPP product - SDH, GigE/FE, ATM. Lucent, Nortel I would dispute - just adding a couple of 10/200 interfaces into a 10-year old SDH ADM doesn't really class as an MSPP, and Nortel don't have an MSPP product for the SDH market only - ditto Marconi until their new products are delivered mid 2003(I don't class a couple of Ethernet tail-links on a 1990s SDH ADM as an MSPP). Fuji in Europe definitely don't have one - SDH ADMs/muxes only, and very few customers (mainly BT Access). I think this iss more of the manufacturers jumping on the Marketing/analyst bandwagon since the focus is moving away from trad. SDH ADMs to the next-gen stuff.

re: Nortel Expands Metro SDH Line What are the numbers for Fujitsu with respect to installed next-gen SDH devices compared to :

- Alcatel >30,000
- Lucent > 25,000
- Nortel > 20,000

assuming the "broad" definition for next-gen as: "next-generation SDH platforms that combine add/drop multiplexing and crossconnect capabilities with multiservice interfaces".[I assume multiring termination is a given as well.]

What is also of interest is how do the numbers map into how many devices with a maximum line-rate of STM-1/4/16 or 48.

The manufacturers saying so many thousands is interesting but has limited value if they are adding the numbers for different maximum rate SDH boxes together.
