audio-wires {four-wires | two-wires}
config>port>voice
This command configures the number of audio wires to be used for audio transmission for an E&M interface.
A change in the number of audio wires may also require a change in the tlp-rx and tlp-tx values.

two-wire operation. This parameter is not valid if the corresponding port or channel’s signaling type is 4W transmission.
[no] em
config>port>voice
This command enables the context to configure channel group parameters for a channelized E&M voice interface.
The no form of this command deletes the E&M channel group.
n/a
fault-signaling {idle | seized}
config>port>voice>em
config>port>voice>fxo
config>port>voice>fxs
This command configures a voice channel for idle or seized fault signaling.
On the 6-port E&M Adapter card, this command is valid only if signaling-mode is configured for E&M signaling. The 6-port E&M Adapter card also supports configuration of the idle and seized codes.
Configuration of the idle and seized codes is not supported on the FXO and FXS channels on the 8-port Voice & Teleprotection card, or on the 8-port FXO Adapter card or 6-port FXS Adapter card. The code transmitted depends on signaling type and companding law as shown in Table: Idle and Seized Codes for FXO and FXS Signaling Types.

[no] fxo
config>port>voice
This command creates a Foreign Exchange Office (FXO) channel on a channelized voice interface. This command applies to the 8-port FXO Adapter card and the 8-port Voice & Teleprotection Card.
The no form of this command deletes the port’s FXO channel.
n/a
[no] fxs
config>port>voice
This command creates a Foreign Exchange Subscriber (FXS) channel on a channelized voice interface. This command applies to the 8-port Voice & Teleprotection card and 6-port FXS Adapter card.The no form of this command deletes the port’s FXS channel.
n/a
idle-code abcd-code
no idle-code
config>port>voice>em
This command defines the ABCD signaling code to be transmitted when the voice channel is configured to transmit idle fault signaling. The command is also used for driving/scanning the E&M signaling leads.
This command is valid only on the 6-port E&M Adapter card and only if signaling-mode is configured for E&M signaling.
The no form of this command reverts to the default value.

line-balance {nominal | 800}
config>port>voice
This command configures the line balance for the FXO or FXS voice interface on the 8-port Voice & Teleprotection card, for the FXO voice interface on the 8-port FXO Adapter card, and for the FXS voice interface on the 6-port FXS Adapter card.

loopback {internal-analog | internal-digital}
no loopback
config>port>voice>em
config>port>voice>fxo
config>port>voice>fxs
This command puts the specified port or channel in loopback mode. The internal-digital parameter is the only valid option for FXO and FXS.
The loopback command is not saved to the system configuration between boots.
The no form of this command disables the loopback.
no loopback
places the associated port or channel into an internal analog loopback mode. The internal analog loopback resides in the CODEC, close to the line side. It loops the outgoing analog signals back towards the system. For E&M ports, the loopback analog signal may be looped back at a different signal level due to gain/loss circuits outside of the CODEC being bypassed.
places the associated port or channel into an internal digital loopback mode. The internal digital loopback resides in the CODEC, close to the system side. It loops the outgoing frames back towards the system.
ring-generation {16 | 20 | 25}
no ring-generation
config>port>voice
This command configures the frequency of the generated ring signal for the specified FXS voice port.
This command does not apply to FXO or E&M ports.
The no form of this command reverts to the default value.

This command defines the ABCD signaling code to be transmitted when the channel is configured to transmit seized fault signaling. The command is also used for driving/scanning the E&M signaling leads.

signaling-type {3600plar | 1511plar | 3600ls | 1511profile1 | 3600re | 1511sn137}
config>port>voice
This command configures how the signaling leads operate to establish a call. To change this parameter, the voice channel must be shut down first.
For FXO, 3600ls, 1511profile1, 3600re, and 1511sn137 are the only valid options; 1511profile1, 3600re, and 1511sn137 support A-Law companding, and 3600ls supports Mu-Law companding.
For FXS, all signaling types are supported; 3600plar supports both A-Law and Mu-Law companding, 1511plar, 1511profile1, 3600re, and 1511sn137 support A-Law companding, and 3600ls supports Mu-Law companding.

signaling-mode {em | transmission-only}
config>port>voice>em
This command configures the signaling mode for the specified port or channel. This configuration is done for groups of three ports (ports 1 to 3 and ports 4 to 6). The first port to be configured in the group sets the signaling mode for the other ports in the group. For example, if port 1 is set for transmission only, ports 2 and 3 must also be set for transmission only, and if port 4 is set for E&M signaling, ports 5 and 6 must also be set for E&M signaling. To change the signaling mode of a port, all ports in the group must first be deconfigured.
