DTR Pulse Width
A Data Terminal Ready (DTR) Pulse is sent at the hardware level to determine a port is
still synchronized with its far end connection. The Pulse Width is the number of 100 milli-
second increments that the pulse lasts. This only displays if the port is using PPP as its
encapsulation type.
DTR Pulse Count
A Data Terminal Ready (DTR) Pulse is sent at the hardware level to determine a port is
still synchronized with its far end connection. The Pulse Count is the number of pulses
generated when a line is down. This only displays if the port is using PPP as its encapsu-
lation type.
Loopback Timeout
Sets the transition time between proprietary messages sent over the link. These messages
are analyzed to determine whether the link is in a loopback state. This only displays if the
port is using Frame Relay as its encapsulation type.
Connection Function
On serial ports using PPP, it is possible to configure the port to be a DTR dial backup
port. In case the primary WAN port fails, a DTR dial backup port will use a synchronous
modem to dial out and reestablish the WAN connection. If this feature is disabled, the
Connection Function field will read Dedicated . If it is enabled, the field will read DTR-Dial ,
and the following options will also be displayed:
200) Connect Timeout (seconds) ............................ 60
201) Retry Delay (seconds) .................................... 10
Connect Timeout
The number of seconds the switch attempts to establish a connection via this port
before declaring the attempt a failure. The valid range is 10 to 2147483647. The
default is 60. If the value is entered as 0, the attempt will never timeout.
Retry Delay
The number of seconds after a connection failure the switch waits before attempting a
new connection. The valid range is 1 to 2147483647. The default is 1.
