Enabling E&M non-signaling mode
Analog E&M provides only one private line, which cannot meet the requirement of large-capacity private lines. Therefore, digital E&M non-signaling should be supported by the VE1/VT1 interface. The calling process is similar to that of analog E&M signaling except that digital signals are used instead of analog signals. In this way, a VE1 interface can provide 30 private lines, and a VT1 interface can provide 23 private lines, thereby enlarging the system capacity.
This feature should be used with the PLAR function, you must also execute the private-line command on the calling voice gateway. For more information about the PLAR function, see "Configuring dial plans."
Before you enable E&M non-signaling mode, E&M signaling must operate in immediate start mode.
For more information about the analog E&M non-signaling mode, see "Configuring E&M voice subscriber line."
