How to Configure Layer 1 Features

Cisco IOS Release 12.0(27)S1

Setting the Clock Source on a T1 Line

You can set the internal or line (network) clock source for a T1 line with the tug-2 tug-2-number

t1 t1-line-number clock source {internal | line} AU-3 configuration command. Table 6 describes the

syntax of this command.

Note On a T1 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 selects internal clocking for the first T1 line in the fourth TUG-2:

Router(config)# controller sonet 6/0

Router(config-controller)# au-3 1

Router(config-ctrlr-au3)# tug-2 4 t1 1 clock source internal

Router(config-ctrlr-au3)#

• The following example selects line clocking for the first T1 line in the fourth TUG-2:

Router(config)# controller sonet 6/0

Router(config-controller)# au-3 1

Router(config-ctrlr-au3)# tug-2 4 t1 1 clock source line

Router(config-ctrlr-au3)#

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

Router#

If the connection fails, verify that you have the correct IP address for the destination and that the device

is active (powered on), then repeat the ping command.

Proceed to the next section, “Using T1 Interface Loopback Modes,” to finish checking network

connectivity.

Table 6 T1 Line Clock Source Command Syntax

Range Description

tug-2 tug-2-number 1 to 7 When framing is SDH, AUG mapping is AU-3, and

mode of operation is c-11, tug-2-number is a number

in the range from 1 to 7.

t1 t1-line-number 1 to 4 In c-11 mode, a number in the range from 1 to 4.

clock source {internal |

line}

internal or line Defines the clock source for the T1 line. The default

clock source is internal.
