Intf Type
This column indicates the physical cable type connected to this port. This cable type is auto-
matically sensed by the
WSX hardware. This column indicates the cable type and whether it is
DCE or DTE . The following values may display in this column
• V35DTE (V.35 DTE cable)
• V35DCE (V.35 DCE cable)
• 232DTE (RS-232 DTE cable)
• 232DCE (RS-232 DCE cable)
• X21DTE (X.21 DTE cable)
• X21DCE (X.21 DCE cable)
• 530DTE (RS-530 or RS-449 EIA DTE cable)
• 530DCE (RS-530 or RS-449 EIA DCE cable)
• T1 (T1 port)
• E1 (E1 port)
The WSX sees RS-530 and RS-449 cables the same because they are electrically identical.
However, this does not affect the operation of either cable type. Both RS-530 and RS-449
cables are supported. If no cable is connected to a port, then this column will display
*NONE*
If an error has been detected on the port (e.g., cable type could not be detected), then the
following value displays:
ERROR!
Speed BPS
This column indicates the speed, or access rate, between the WSX serial port and DSU or other
“physical” DTE device. The speed is expressed in bits per second (bps). This speed is the total
available bandwidth on the line connected to this port. Virtual circuits on this port share this
bandwidth.
Usually, the WSX port will be a physical DTE device and the speed will be determined by the
DSU . In this case, this value will read EXT CLK , which means the WSX port gets its clocking
from an externally attached DCE device (i.e., DTE cable plugged into WSX port) or no cable is
attached. If the WSX port is a physical DCE device (i.e., DCE cable plugged into WSX port),
then this value will be the actual clock rate used by the port. The speed on a T1 port will
always be 1544000; the speed for an E1 port will always be 2048000.
