How to Configure Layer 1 Features

Cisco IOS Release 12.0(27)S1

Setting the Clock Source on an E1 Line

To specify where the clock source is obtained for an E1 line, use the tug-2 tug-2-number e1

e1-line-number clock source {internal | line} TUG-3 configuration command, where:

• tug-2-number is a number in the range from 1 to 7.

• e1-line-number is a number in the range from 1 to 3.

• internal specifies that the internal clock source is used. The default clock source is internal.

• line specifies that the network clock source, recovered from the received signal, is used.

Note On an E1 circuit, one end must provide the clock source by using the internal clock source.

The other end of the circuit can use either line or internal as the clock source.

• The following example shows how to instruct E1 line 1 to use an internal clock source.

Router(config)# controller sonet 6/0

Router(config-controller)# au-4 1 tug-3 2

Router(config-ctrlr-tug3)# tug-2 4 e1 1 clock source internal

Router(config-ctrlr-tug3)#

• The following example shows how to instruct E1 line 3 to use a line clock source.

Router(config)# controller sonet 6/0

Router(config-controller)# au-4 1 tug-3 2

Router(config-ctrlr-tug3)# tug-2 4 e1 3 clock source line

Router(config-ctrlr-tug3)#

Setting the National Bits on an E1 Line

To configure the national reserve bit pattern for an E1 line, use the tug-2 tug-2-number e1

e1-line-number national bits pattern TUG-3 configuration command, where:

• tug-2-number is a number in the range from 1 to 7.

• e1-line-number is a number in the range from 1 to 3.

• pattern is a value in the range from 0x0 to 0x1F (hexadecimal) or 0 to 31 (decimal). The default

value is 0x1F (or 31).

The following example sets the national bit pattern to 0x0 on the first E1 line in the fourth TUG-2.

Router(config)# controller sonet 6/0

Router(config-controller)# au-4 1 tug-3 2

Router(config-ctrlr-tug3)# tug-2 4 e1 1 national bits 0x0

Router(config-ctrlr-tug3)#

Using the ping Command to Verify Network Connectivity

Following is an example of a successful ping command to a remote server with the address 10.0.0.10:

Router# ping 10.0.0.10

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echoes to 10.0.0.10, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 ms
