3088.0. "Some quick config questions" by SMURF::CORCORAN () Tue Dec 19 1995 15:44

I have a site with fiber coming into the premises and that consists of the
following: 3 floors,  12 faceplates with Level 5 twisted pair (4 pair)
terminating in RJ45 jacks and 14 faceplates with two RJ45 jacks (also Level 5
twisted pair).

Can this site be supported with a DEChub 90 consisting of 2 DECrepeater 90T,
2 DECrepeater 90FA, and a DECserver 90TL?  Will I get 32 terminal server ports
from this equipment?  What might this configuration look like?  Also, does
anyone know what a Gator-Star is and why one would use it instead of splitting
the telephone leads? Thanks.

3088.1Call your nearest Network Services Sales Exec.MSDOA::REEDJohn Reed @CBO = Network ServicesTue Dec 19 1995 18:4932
    Hello.
    
    It sounds like a quick trip to the OPEN DECconnect Applications Guide
    is required for this project.
    
    You have nicely described the physical cable, (40 lines of 4-pair) but
    you have not described the USER requirements for the building.
    
    The DECrepeater 90T is an eight-port repeater, which will service up to
    eight offices, (within a 90 meter radius of the repeater) of high speed
    10BaseT Ethernet PC's, or other 10Meg device (such as a HP Jetdirect,
    or Alpha File server).   The DECserver 90TL will service up to 8 (eight) 
    asynchronous ports (either printers or video terminals)
    
    	You must look up the requirements of this customer more
    specificaly, and read the sections of OPEN DECconnect Applications
    Guide which gives you very helpful lists of required hardware for
    applications such as yours.   The catalog includes the jumpers, and
    line cords, and the exact cabling needs for the customer.  You will
    need MORE than just the HUB and modules (line cords, NIC cards,
    passive adapters, fiber jumpers etc.) so the exact bill of materials
    cannot be determined through a Notes Conference.
    
    I would suggest that you contact your local Network Services people,
    and ask them to assist you.  We are available for a quite reasonable
    fee, or if your customer does not wish to pay, you can call
    1-800-DEC-SALE, and they can help you more specifically.  It sounds
    like you know the hardware you need, but the precise quantity and 
    supporting cabling still needs to be determined.

3088.2Pointer to App Guide?SMURF::CORCORANFri Dec 22 1995 13:083
    Can anyone give me a pointer to the OPEN DECconnect Applications Guide?
    Is it available online? Thanks.
3088.3Get at least 10 when you order.MSDOA::REEDJohn Reed @CBO = Network ServicesSat Dec 23 1995 00:069
    The OPEN DECconnect Applications Guide is available through LOS, see
    note NETCAD::OPEN_DECCONNECT entry 44.*.
    
    I don't think that it's online, but it might be.  I always order 10 to
    20 of them, and give them to MIS and NETWORK managers at my customer
    sites.  These are considered Bibles by the network physical layer
    people.  There is a great deal of information available here.
