Obtaining Status and Statistical Information

Page 29-39

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.
