Carrier Communication Port’s External Device Commands. Specifies the
communication port’s external device commands. When this configuration option is
disabled, no commands are sent out the communication port. Select AT to have
standard attention (AT) commands sent out the communication port to control the
external device. Select Other to configure the connect prefix, the connect indication
string, the escape sequence, the escape sequence delay, and the disconnect string.
Disab – Allows no commands to be sent out the communication port.
AT – Allows standard AT commands to be sent out the communication port.
Other – Allows user configurable commands to be sent out the communication port.
NOTES: – This configuration option is available on carrier-mounted DSU/CSUs
only.
Y
– This configuration option is not available if the communications port is
disabled.
– Carrier Detect (CD) is used to detect that the external device’s
connection is lost. Therefore, do not allow the CD lead to be forced on
by the external device.
– The external device should be strapped to ignore Data Terminal Ready
(DTR).
ComConnPrefix:
Next Edit Clear Prev
Carrier Communication Port Connect Prefix. Specifies the connect prefix to the dial
directory phone number. When you make a connection or the DSU/CSU automatically
makes a connection (dial-out alarms or traps) through the communication port, the
connect prefix and the dial directory phone number are used to establish the
connection. The connect prefix is an ASCII text string and may be up to 20 characters in
length. If the connect prefix is NULL, then no connect prefix is used.
Edit – Allows you to edit and/or display the connect prefix using the generic text string
entry screen.
Clear – Allows you to clear the connect prefix. The connect prefix is set to a null string.
NOTES: – This configuration option is available on carrier-mounted DSU/CSUs
only.
Y
– This configuration option is not available if the ComExtDev configuration
option is set to AT or the communication port is disabled.
– If ComExtDev is configured for Other and the external device requires
characters after the dial phone number, you must append the characters
to the phone number.
