3695.0. "DEREN to DECrepeater 90FL??" by HERON::codger.vbo.dec.com::HEMMINGS (Lanterne Rouge) Wed Jul 10 1996 11:34

A customer wants to know if he can connect a DEREN to say a DECrepeater 90FL - 
seeing they are both fibre devices I suppose he can but are they to the same 
specs and more importantly, will they work?

According to my 1991 catalogue, DEREN's are DECrepeater 200's,

the -RC and -RD versions are called remote repeaters and are called IEEE 
802.3/Ethernet(FOIRL) compatible.

the -RP and -RQ versions are marked IEEE 802.3/Ethernet compatible only with 
-RP or -RQ or LANbridge 150.

From this I suspect that the first two have a chance, but the second two do 
not, which is a pity because the customer has -RQ's!

Any comments, anyone??

    Only the FOIRL-compatible DEREN variants will work with a DECrepeater
    90FL.   The fiber optic links used by the LANbridge 100/150 and the
    DEREP (DECrepeater 100) pre-date both the FOIRL and 10BASE-F standards
    and are not compatible with them.
