re: Making Sonet Ethernet-Friendly The Overview reads, "To provide incremental service provisioning, carriers are looking to deliver services over Gigabit Ethernet in multiples of 50 Mbit/s."

Shouldn't that have read "... 1.5 Mbit/s"?

re: Making Sonet Ethernet-Friendly "The Galazar MSF250 is the only device now available that supports both high- and low-order VCAT."

Doesn't Transwitch's Ethermap-3 chip support both high and low order VC?

re: Making Sonet Ethernet-Friendly It is really not clear what solutions are available and what solutions are T.B.S. (To Be Sampled ;-)

Agere :- MARS2G5VC (old TADM2G5VC)
Agilient :- HDMP-3001
Cypress :- POSIC2GVC
PMC-Sierra :- Arrow2xGE
Transwitch :- Ethermap3
Vittesse :- VSC9115(OC-48)/VSC9118(OC-192)
WestBay :- WB4500

Pending sample ??
AMCC :- Volta48 and Volta192 (Q3/Q4 2003 from PR)
Agilient :- HDMP-3002 (OC-48)????
Galazar :- MSF250 ????
Multilink :- VCAT-10 ????
Transwitch :- Ethermap48 ????

Comments anyone?

re: Making Sonet Ethernet-Friendly I am looking for a solid network consulting firm and I have heard about these guys, ParrishNet, and I was wondering if anyone here has used them and if so how are they?

re: Making Sonet Ethernet-Friendly I think you're right about the EtherMap-3. The Galazar part looks like the only one that can support HO and LO VCAT all the way up to OC-48.

As my name might suggest, now that I am typing, I would be remiss not to point out a couple of other innaccuracies I noticed in my first read through.

1. Based on presentations I've seen and the information available on the web, the EtherMap-48 is 24 channel device, not 48 (4xGigE or 24x10/100 direct).

2. The WB4500 from West Bay has H/W 'hooks' for external generation and interpretation of LCAS control messages. From the West Bay website: 'The WB4500 offers hardware hooks to insert and extract the LCAS control packets allowing for on-demand bandwidth provisioning.'

There's probably a few more, but it looks like a pretty good summary to me.

re: Making Sonet Ethernet-Friendly I'm not quite sure what the question is here. The last column in the table states whether devices are available (either sampling or in production) or are planned to sample (in the quarter given).

The only devices covered by the report that are not sampling yet are the Galazar MSF250 (planned for Q1 2003) and the Multilink VCAT-10/Varakai and Transwitch Ethermap48 (both planned for Q2 2003).

The AMCC Volta48 and Volta192 were announced after the report was compiled and will be added when we update the report.

re: Making Sonet Ethernet-Friendly As far as I am aware Agilient is not sampling the HDMP3002, word on the street is that it is cancelled.

However I would be happy to be contradicted since it looked a good device on paper.

re: Making Sonet Ethernet-Friendly The HDMP-3002 has, in fact, been cancelled--or rather, indefinitely postponed.

Does anyone know the reason?

re: Making Sonet Ethernet-Friendly Just noticed your note in an old message. As a matter of fact, yes I have. Quick response, good people to work with, very thorough and competitive pricing. I liked their personal attitude and the fact they seemed to want my business rather than just tolerated my contact.
