connection {plar | trunk } string
no connection {plar | trunk } string
Syntax Description
Default
No connection.
Command Mode
Voice-port configuration.
Usage Guidelines
Use the connection command to specify a connection mode for a specific interface. Use the connection
plar command to specify a PLAR interface. The string you configure for this command is used as the
called number for all calls coming in over this voice port. The destination dial peer is determined on the
basis of this called number.
Use the connection trunk command to specify a straight tie-line connection to a PBX. This command
can be used for E&M-to-E&M trunks, FXO-to-FXS trunks, and FXS-to-FXS trunks. Signaling is
transported for E&M-to-E&M trunks and FXO-to-FXS trunks; signaling will not be transported for
FXS-to-FXS trunks.
If the connection command is not configured, the standard session application creates a dial tone when
the interface goes off-hook until enough digits are collected to match a dial peer and complete the call.
Example
The following example selects plar as the connection mode and a destination telephone number of
14085559262:
voice port 0/0
connection plar 14085559262
The following example selects trunk as the connection mode and a destination telephone number of
