Enabling E&M Non-Signaling Mode; Enabling E&M Analog Control Signals Pass-Through - HP FlexNetwork MSR Series Configuration Manual

Enabling E&M non-signaling mode
The E&M non-signaling mode is applied when the E&M interface of the peer device does not provide
the M line and E line. In this mode, the E&M interface communicates with the peer end without
signaling. You can configure the private line auto ring-down (PLAR) function by using the
private-line command to form a three-segment E&M virtual private line (E&M-VoIP-E&M). When a
subscriber picks up the phone, a number is automatically dialed out through the E&M virtual private
line.
Configuration guidelines
•
This feature should be used with the PLAR function, and you must 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, the E&M signaling must operates in the
immediate start mode.
•
For more information about digital E&M non-signaling mode, see "Configuring digital voice
subscriber lines."

Enabling E&M analog control signals pass-through
This feature operates only when E&M has no signaling enabled. As shown in
Generator and the radio establish an E&M virtual private line. Enable E&M analog control signals
pass through for Router A and Router B so that they can send occupied and idle signals for the E&M
virtual line over the IP network.
