2664 CHAPTER 175: E1 AND T1 CONFIGURATION COMMANDS

You may set a signal value to 16 to indicate that the signal function does not exist. For example, if the send last digit signal is not available in a national R2 signaling variant, you may set the value for req-lastfirstdigitto 16.

The purpose of the register-valuecommand is to assign values for signals requesting responses from the remote end. For example, after you configure the register-value callingcategory command, the terminating point sends the send calling category signal with the specified value to the originating point for the calling category.

This command applies to R2 signaling only.

n As some national register signal coding schemes may not support all the register signals mentioned in this section, you are recommended to use defaults unless necessary. For example, the ITU-T recommendation is available with the send calling category signal (the callingcategory keyword) but not the send billing category (billingcategory) signal.

Related command: group-b enable.

Example # Request the originating point to send calling category by configuring a backward signal (signal value 7).

View R2 CAS view

Parameter ABCD: Defines the default of each signal bit in transmission. Each bit can take the value of 0 or 1. The default C and D bit values vary by country mode.

Description Use the renew command to configure the values of C bit and D bit in R2 signaling.

Use the undo renew command to restore the default. The default value varies with R2 signaling standards in countries.

This command applies to R2 signaling only.

R2 signaling uses bits A and B to convey real status information while leaving bits C and D constant. The values of bits C and D are national variant dependent. For example, they are fixed to 01 in most countries but 11 in some other countries.
