Binding An Fxs Voice Subscriber Line To An Fxo Voice Subscriber Line; Configuration Prerequisites; Configuration Procedure - HP FlexNetwork MSR Series Configuration Manual

Binding an FXS voice subscriber line to an FXO
voice subscriber line
The one-to-one binding between FXS voice subscriber lines and FXO voice subscriber lines
enhances the reliability of voice communication, which is particularly important for some industries.
After the binding, FXO voice subscriber lines can be used for communication over PSTN when the IP
network is unavailable.
The one-to-one binding between FXS voice subscriber lines and FXO voice subscriber lines
provides the following functions:
•
Dedicated FXO voice subscriber lines—The FXO voice subscriber lines are used only for the
bound FXS voice subscriber lines and PSTN-originated calls received over the FXO voice
subscriber lines are directly connected to the bound FXS voice subscriber lines.
•
Consistent state between bound FXS and FXO voice subscriber lines—The
on-hook/off-hook state of the bound FXS and FXO voice subscriber lines is consistent. If an
FXS voice subscriber line receives a PSTN-originated call when the corresponding FXS voice
subscriber line goes off-hook, the calling party will hear busy tones.

Configuration prerequisites

The router is equipped with FXO and FXS interface cards. The basic functions of FXO and FXS
