Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 9

An administrator is trying to change the default LINECODE for a voice ISDN T1 PRI. Which command makes this change?

Answer options

• A. linecode esf
• B. linecode ami
• C. linecode hdb3
• D. linecode b8zs

Correct answer: D

Explanation

The correct command is 'linecode b8zs', which is used to set the B8ZS line coding for T1 PRI. The other options, while also valid line codes, do not set the same default configuration as B8ZS, which is specifically designed to handle long strings of zeros effectively.
