To change the clock source of the interfaces on a cOC3/STM1 I/O module from the
router's clock to the module's clock or vice versa, first change the clock source of all
ports to the line setting, and then to the new internal clock setting.
Example
host1(config-controll)#path 12 e1 1/4/1 clock source line
Use the no version to restore the default value, line.
See path ds1|e1 clock source.
Use to configure the framing format for a T1 or an E1 interface.
For T1, specify esf (extended superframe) or sf (superframe). The default is esf.
The HDLC idle character differs from non–E Series implementations. For T1 interfaces,
if you configure SF, the router sets the HDLC idle character to 0xFF. If you configure
ESF, the router sets the HDLC idle character to 0x7E.
For E1, specify crc4 or no-crc4. The default is crc4.
Choose a framing format that is compatible with the framing format at the other end
of the line.
Example
host1(config-controll)#path 12 e1 1/4/1 framing no-crc4
Use the no version to restore the default value.
See path ds1|e1 framing.
Use to enable SNMP link status processing for a T1 or an E1 interface and its associated
tributary.
The default is disabled.
Example
host1(config-controll)#path 2 ds1 1/1/1 snmp trap link-status
Use the no version to disable SNMP link status processing.
See path ds1|e1 snmp trap link-status.
Configuring T1 Interfaces to Send FDL Messages
You can configure a T1 interface to send FDL messages. To configure FDL:
Specify a SONET interface.
1.
host1(config)#controller sonet 8/0
Specify the standard for transmission of FDL messages on both ends of the T1
2.
connection.
host1(config-controll)#path 2 ds1 1/1/1 fdl ansi
