Voice Subscriber Lines; Voice Entities - HP FlexNetwork MSR Series Configuration Manual

Operation
6. Configure number application for the dial plan adopted in the network
diagram.
7. Configure the following voice protocols according to the service and
networking environment:
H.323 protocol
SIP protocol
Fax protocol
8. Check whether the network requirements are met:
If so, the configuration is completed.
If not, check the fault and perform re-configuration.

Voice subscriber lines

Voice subscriber lines, which are connected to telephone network devices such as analog telephone
and PBX, implement all physical layer functions between VoIP gateways and PSTN devices. These
functions include power supply to analog telephones, off-hook state detection, ringing signal
generation, receiving & sending of analog or digital voice calls, and receiving & sending of dialed
digits for call routing.
For more information about the voice subscriber line, see "Configuring analog voice subscriber lines"
and "Configuring digital voice subscriber lines." The router provides the following voice subscriber
lines:
•
FXS analog voice subscriber line, corresponding to an FXS interface. FXS analog voice
subscriber lines are usually connected to FXO subscriber line terminals, such as ordinary
analog telephones, to provide ringing current, ringing voltage, and dial tone.
•
FXO analog voice subscriber line, corresponding to an FXO interface or 2-port loop trunk
interface. FXO analog voice subscriber lines are usually connected to analog telephone
interfaces of PSTN central offices (PBXs).
•
E&M analog voice subscriber line, corresponding to an E&M interface. E&M analog voice
subscriber lines support analog E&M signaling and divide each voice connection into a trunk
circuit side and a signaling unit side (similar to the relationship between DCE and DTE). PBXs
send signals to routers through M lines and receive signals from routers through E lines.
•
Digital E1/T1 voice subscriber line, that is, a TS set or PRI group created on a VE1/VT1
interface card. After a TS set or PRI group and signaling types, such as R2 signaling, digital
E&M signaling, or digital LGS are configured on VE1/VT1 voice interface cards, the system will
automatically generate the corresponding voice subscriber line for the TS set or PRI group. If a
TS set is created, the E1/T1 interface supports R2, digital E&M, and digital LGS signaling. If a
PRI group is created, the E1/T1 interface supports ISDN, where DSS1 and QSIG are commonly
used protocol types.
•
BSV voice subscriber line, which supports ISDN. Generally, a BSV interface is used to connect
an ISDN digital telephone, or used as a trunk interface to connect a PBX digital trunk.

Voice entities

For information about voice entity configuration, see "Configuring voice entities", "Configuring VoFR",
and "Configuring customizable IVR."
There are four kinds of voice entities: POTS entity, VoIP entity, VoFR entity, and IVR entity.
•
A POTS entity corresponds to the local telephone (or PSTN) side. POTS entity configuration
associates a voice subscriber line on the VoIP gateway with a local telephone. The POTS entity
configuration also implements the binding between telephone numbers and voice subscriber
lines.
