the no form of the command to restore the default line-code type of transmission.

The syntax for this command is:
For T1 lines:

 {ami|b8zs}

For E1 lines:

 {ami|hdb3}

Use this command in configurations where the router or access server must 

communicate with E1 or T1 fractional data lines. The T1 service provider 
determines which line-code type, ami or b8zs, is required for your T1 circuit. The 
E1 service provider determines which line-code type, ami or hdb3, is required for 
your E1 circuit. 

Example:
The following example specifies B8ZS as the line-code type for a T1 line:
X330WAN-2DS1-1(config-controller:1)# linecode b8zs

Example:
X330WAN-2DS1-1(config-controller:1)# no linecode

Use the loopback diag command to put the T1 or E1 line into loopback mode. 

Regarding the use of loopbacks during line setup and maintenance, only one 

type of loopback can be defined at any given time.
