Compatible Systems OCTAL V.35 - Manual (Page 7)

Chapter 1 - Network Installation 3
Telco Line Connection Requirements
The Octal V.35-10/100 is not a line communications device. In order to connect each V.35 port
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 you are
connecting to.
v Note: Before attempting to connect the Octal V.35-10/100 to a leased telco line, use the
loopback features of your CSU/DSUs 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 Octal V.35-10/100 RIOP is shipped with two “Quad” cables. These cables have a single
Very High Density D-Sub connector which plugs into one of the Quad V.35 interface ports on
the front of the device and then divides into four separate High Density D-Sub (HD D-Sub)
female interface cables.
v Note: Port numbers 0 - 3 are stamped on both sets of Quad cables. For ports 4 -7, the
connector marked “Port 0” is Port 4, the connector marked “Port 1” is Port 5, etc.
In addition, there are eight HD D-Sub male to V.35 male adapter cables. The V.35 male
connector plugs into the female V.35 connector on the chassis of the V.35 line communications
device. The pin outs for this cable are shown in Appendix A.
v Note: Please use only the supplied cables when connecting your V.35 line communication
device to the Octal V.35-10/100 RIOP’s interfaces. The cables provided with other equipment
will generally not have the same internal connections.
Connecting a Line Device to the V.35 Interfaces
These interfaces can be used to connect to a wide variety of line communications devices,
including those which support either leased or dialed operation. Examples include leased 56K
CSU/DSU’s, switched 56K CSU/DSU’s, fractional T1 CSU/DSU’s, ISDN terminal adapters,
and full T1/E1 rate CSU/DSU’s.
Make sure that both units are powered off. First connect one of the eight V.35 adapter cables to
the line communications device. Then connect one of the Quad cables to one of the V.35 inter-
faces on the front of the router. Lastly, connect the two cable ends together. With each connec-
tion, make sure to fasten the captive screws into the jack screws on either side of the connec-
tors.
Connecting a Management Console
If you wish to connect an out-of-band management console, use the supplied DB-25 male to
DB-25 female console cable and connect to the Console interface on the Octal V.35-10/100
RIOP. You can use a dumb terminal or a computer equipped with VT100 terminal emulation.
The default settings for the Console interface are VT100 terminal emulation, 9600 bps, 8 bits,
no parity, 1 stop bit and no Flow Control.
v Note: The Octal V.35-10/100 RIOP also has an AUX interface. This is a modem connection
which should only be used in consultation with Compatible Systems Technical Support staff,
who will provide instruction on its use.
Powering Up the Router
Connect the supplied power cord to the front of the VSR and set the power switch to “On.” At
power-up, the router will take approximately one minute to become visible to CompatiView.
v Note: If you want to use Telnet as a management method, you must first configure an IP
address into the router with an out-of-band console, or reconfigure the IP address on an IP
host or workstation on the same Ethernet segment as the router. See the appropriate VSR
chassis section of the manual for more information on Command Line Management.
