The Northeast Government Accounts Group (NGAG) is currently having a bit of
difficulty competing with Synernetics' LANplex 5004 modular hub in an FDDI/
Ethernet extended LAN configuration.  Digital's hardware totaled $360K, at 21%
discount for the configuration.  Synernetics' hardware solution was quoted at 
$185K.  This is almost 1/2 of Digital's quote!
I am checking further into the proposed configuration to see if we are comparing
equivalent solutions.  I also have a technical question that I would like to
have some assistance with.  I believe that the following is a representation
of part of the network configuration.  Doesn't this break the "2 repeater"
Ethernet rule?
	+-------------------+
	|  LANplex 5004     |
     A  |-------------------|  B
    ----|  FDDI Enterprise  |----      punch-
    ----|  Access Module    |----      down

	|  Module (10BASE-T |----------|    |------REPEATER------ ThinWire drops
	|  Repeater)        |----------|    |------REPEATER------ ThinWire drops
	|-------------------|          +----+
	|  Spare slot       |

	|  Spare slot       |

Aren't there 3 repeaters between the ThinWire stations on different 10BASE-T
ports?  This configuration is also shown in Synernetics' marketing literarure.

| The Ethernet conference is a better place for the repeater question. On the cost comparison: could you show what the configuration looks like? I assume the piece you drew was just a small part, since that clearly doesn't come anywhere near $100k. paul | |||||
