(Optional) Enable processing of SNMP link status information about an interface.
5.
Configure the T1 line parameters.
6.
You can specify parameters for a single channel, multiple individual channels, ranges
of channels, or any combination of the three types of specifications. For example:
host1(config-controll)#path 12 ds3 1 t1 25-28
(Optional) Enable processing of SNMP link status information about a channel group.
7.
Use to create and configure the T1 path over SONET and SDH interfaces.
Example
host1(config-controll)#path 12 ds3 1 t1 25-28
Use the no version to delete a path.
See path ds3 t1.
Use to configure the transmit clock source for the T3 line.
Use a transmit clock recovered from the line's receive data stream, except in rare cases
such as back-to-back router tests. When performing back-to-back router tests,
configure one end of the line as internal and the other end as line.
Specify the keyword line to use a transmit clock recovered from the line's receive data
stream.
Specify the keywords internal module to use the line module's internal clock.
Specify the keywords internal chassis to use the router's clock.
On a cOC3/STM1 I/O module, you can configure some ports with internal clock sources
and others with line clock sources. However, all ports with internal clock sources must
use either the router's clock or the module's clock. You cannot configure some ports
on the I/O module to use the router's clock and others to use the module's clock.
To change the clock source of the ports on a cOC3/STM1 I/O module from the router's
clock to the module's clock or vice versa, change the clock source of all ports first to
the line setting, and then to the new internal clock setting.
Example
host1(config-controll)#path 12 ds3 1 t1 28 clock source internal chassis
Use the no version to restore the default value, line clocking.
See path ds3 t1 clock source.
