Cabletron Systems SPECTRUM 1800 User Manual page 115

The X.25 Physical Port ConÞguration window provides the following
conÞguration information:
Speed
This Þeld speciÞes the data transmission rate in bits per second. If this port is a
physical DTE, specify the line speed that matches the speed of the device
connected directly to the port. If the port is a physical DCE (i.e., the attached I/O
cable is DCE) specify the clock speed of the serial port you are conÞguring.
Possible line speed entries are:
If you enter a value that is within the valid range but not equal to one of the
values listed above, the speed will be rounded up. If an RS-232 DCE port is
directly connected to the DTE via the standard Cabletron cable, the maximum
supported speed is 64000. If longer cabling is used, the maximum speed is 19200.
Inactivity Timer
The Inactivity Timer only has a function if the port you are conÞguring is a dial
port; that is, if the port is connected to a dial modem. Use this Þeld to specify an
amount of time (in minutes) that starts as soon as there are no active connections
on a dial port. If the port is a dial-out port, and no new connections are
established before the speciÞed time expires, the port will be disabled until the
next call is placed. If the port is a dial-in port, and no new connections are
established before the time period expires, the port will be disabled until the
Disconnect Timer expires.
Disconnect Timer
The Disconnect Timer only has a function if the port you are conÞguring is a dial
port; that is, if the port is connected to a dial modem.This Þeld speciÞes the length
of time (in seconds) that a dial-in port will remain disabled after the Inactivity
Timer expires.
