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.

MAX Retries

This is the maximum number of times the port will attempt to send a frame if the
physical unit (PU) is not responding. A larger value increases the probability of an
eventual correct transfer between DTE and DCE, but a smaller value permits
faster detection of a permanent error condition. The default value for this
parameter is 5.

Inactivity Timer

This parameter is only relevant if PAD Type (see below) is HPAD. It is the amount
of time (in seconds) that the FRX will wait with no activity on the port before it
declares the port is down. The default value for this parameter is 50.

Physical Port Interface

The physical port interface is deÞned by the portÕs connector and cabling type,
and must be conÞgured as follows:

¥

For the FRX4000 and SmartSwitch 1800, port 0 and port 1 are always RS-232;

¥

For the FRX4000, ports 2 and 3 are determined by the attached cables: RS-232,
V.35, RS-449, or X.21;

NOTE

If you have installed the optional CSU/DSU card on an FRX4000 or SmartSwitch 1800,
it will logically take port 1, and you must conÞgure certain CSU/DSU parameters
through console management. Refer to your FRX or SmartSwitch 1800 hardware
documentation for more information.
