Compatible Systems 3500R Manuale Utente

To connect the router’s Ethernet interface to a standard (thick) Ethernet 
cable you will need a transceiver cable connection at the correct loca-
tion on your Ethernet cable.  The transceiver cable will attach directly to 
the DB-15 connector on the router.

To connect the router’s Ethernet interface to twisted-pair Ethernet 
cabling you will need an unshielded twisted-pair station cable that is 
connected to a 10BaseT-compatible twisted-pair hub.

v Note:  Ethernet cables and cable connectors are not supplied with the 
RISC Router product.  Please contact your reseller or your Compatible 
Systems representative for information on obtaining the correct 
Ethernet cabling supplies.

The RISC Router 3500R is not a line communications device.  In order 
to connect to a wide area transmission line, you must use a 56K CSU/
DSU, ISDN Terminal Adapter, or T1/E1 CSU/DSU.  Which of these 
devices you use depends on the type of telco line to which you are 
connecting one of the router’s wide area interfaces.

v Note: Before attempting to connect the RISC Router 3500R to a 
leased telco line, use the loopback features of your CSU/DSU to check 
the line.  This can save you a considerable amount of time, since the 
more equipment you have on the line, the more difficult it becomes to 
determine where a problem is occurring.

The RISC Router 3500R provides four high-speed V.35 synchronous 
interfaces, each of which can be independently configured for PPP, 
Frame Relay or SMDS operation.  The V.35 interfaces are capable of 
communicating to another router or a PPP client machine over a 56K 
CSU/DSU, an ISDN Terminal Adapter, or a T1/E1 CSU/DSU.

The RISC Router 3500R includes four V.35 cables.  These cables termi-
nate in a male V.35 connector, which fits the female V.35 connector 
supplied by virtually all V.35 line communications devices.  The 
pinouts for this cable are shown in Appendix B.
