Nice writeup on how the equipment will probably interface

Regarding the confusion surrounding the China Post
contracts, here's my take.
NN has been awarded the core with its 36170 switch.
ASND has been awarded a portion of the edge, primarily
dealing with frame relay aggregation into the ATM network,
with its 9000 switch.
The 9000's primary goal in life is frame relay support.
It is a cell switching box but for all intents and purposes
is a frame relay switch. It can sport lower speed ATM (CES)
ports, and can also supply ATM uplinks (at least at 45Mb/s,
maybe even 155, I have to check to be sure).
Depending on the country's use of frame relay there could
be many of these 9000 switches (hundreds???).
The 36170's, I assume, are being used in place of
ASND CBX 500's (must have been what ASND proposed).
In summary, a good win for ASND, but a much better win
for NN. One must ask why the 36170's were able to beat out
the CBX500...

Regarding your statement:
<<The third paragraph reads, "Ascend recommended its broadband
multiservice switching system B-STDX 9000 as ATM switching equipment
for the network." It goes on to describe the B-STDX and list how
many companies have already used it, yet nowhere does it say this
equipment has been chosen by China Post --- though one wonders why
they've described it. Only by reading the fifth paragraph do you find
out what's actually involved. "In this project, Ascend Communications'
NavisCore will undertake the network administration of up to 100 units
of switching equipment. . . .">>
It would surprise me if Ascend's portion of this contract is
limited to 'network administration' related equipment. As
alluded to in the above post, Ascend providing the frame
relay equipment, that would in turn connect to or uplink
to the NN 36170 ATM switch seems much more likely to me...
and also would fit in with their geographical description of
equipment going into and tying together the different provinces
of China. Just my two cents. Peter. |
