User Interface Configuration Options
ComEscDel: None
Next None 0.2s 0.4s 0.6s 0.8s 1.0s Prev
Carrier Communication Port Escape Sequence Delay. Specifies the delay used while sending the communication port
escape sequence. Use the communication port escape delay to specify the delay before sending the first character of the
escape sequence and the delay after the last character of the escape sequence. During the delay, no data is sent out the
communication port.
None – No communication port escape sequence delay.
X.X
s – The delay used during the communication port escape sequence (where
X.X
is 0.2, 0.4, 0.6, 0.8, or 1.0 seconds).
NOTE: This configuration option is available on carrier-mounted DSU/CSUs only.
Y
NOTE: This configuration option is not available if the ComExtDev configuration option is set to AT or the communication
port is disabled.
NOTE: ComEscDel must be configured for a delay greater than or equal to the escape guard time required by the
external device.
ComDisconnect:
Next Edit Clear Prev
Carrier Communication Port Disconnect String. Specifies the communication port’s disconnect string. The communication
port’s disconnect string is sent to the external device if either you or the DSU/CSU wants to command the external device
to disconnect. The external device must be in command mode before this command can be sent, so the escape
sequence will always be sent before the disconnect string. The disconnect string is an ASCII text string and may be up to
20 characters in length. If the disconnect string is NULL, then no disconnect string is sent out.
Edit – Allows you to edit and/or display the disconnect string using the generic text string entry screen.
Clear – Allows you to clear the disconnect string. The disconnect string is set to a null string.
NOTE: This configuration option is available on carrier-mounted DSU/CSUs only.
Y
NOTE: This configuration option is not available if the ComExtDev configuration option is set to AT or the
communication port is disabled.
Com Type: Async
Next Async Sync Prev
Communication Port Type. Specifies whether the communication port uses synchronous or asynchronous operation when
it is configured as the SNMP management link.
Async – Configures the communication port for asynchronous operation.
Sync – Configures the communication port for synchronous operation.
NOTE: This configuration option is available on standalone DSU/CSUs only.
F
NOTE: This configuration option is not available if the Com Use configuration option is set to ASCII, Daisy, or Term. In
these cases, the communication port is always asynchronous.
Com Clk: Int
Next Int Ext Prev
Communication Port Synchronous Clock. Specifies whether the communication port uses internal or external clocking
when it is configured for synchronous operation.
Int – Configures the communication port for internal clocking.
Ext – Configures the communication port for external clocking.
NOTE: This configuration option is available on standalone DSU/CSUs only.
F
NOTE: This configuration option is not available if the Com Type configuration option is set to Async.
