Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 261

Due to provider requirements, outgoing calls from the Enterprise to the PSTN must start with channel 1.
Which ISDN command changes the channel selection on IOS to meet this requirement?

Answer options

• A. isdn bchan-number-order descending
• B. isdn bchan-number-order ascending
• C. isdn protocol-emulate network
• D. isdn incoming-voice voice

Correct answer: B

Explanation

The correct command, 'isdn bchan-number-order ascending', sets the channel selection to start from the lowest number, which is channel 1. The other options do not configure the channel selection in the required order; 'descending' would start from the highest channel, while the other two commands pertain to different ISDN functionalities.
