System-wide contains system parameters for Cordless (CMI).

9.3.1.1

Area: CMI data

System ID

The System ID is entered in this field as an 8-digit hexadecimal digit sequence.

The following applies here:

1st. digit

E/ARC

Access Right Class

2nd. - 5th. digits

EIC

Equipment Installers Code

6th. - 7th. digits

FPN

Fixed Part Number

8th. digit

FPS

Fixed Part Subscriber

The entry must have 8 digits.

Freq. band

Europe / world:

1.88 - 1.90 GHz

China:

1.90 - 1.92 GHz

Latin America:

1.91 - 1.93 GHz

When reading the CDB data, the value entered is compared with the default, which depends on the country parameters. If there is a deviation, a message is displayed. Depending on the acknowledge, the entry can be retained or overwritten by the default value.

Speech coding

The system-wide speech codec is displayed under Speech coding (a-law, µ-law).

Encryption

Encryption is the encoding of the data at the air interface and can be activated or deactivated (default: active = on).

The time the login window is open can be changed (default: 10 minutes).

9.3.1.2

Area: Echo Handling

These parameters can be used to disable the echo handling set under Trunks | Parameter/General Flags for mobile stations on a node-wide basis. By default, all parameters are set to automatic. The settings are then made in accordance with the line settings of the calls. Potential improvements by general deactivation or line-specific activation must be tested in individual cases.

Echo Suppressor

The Echo suppressor (ES) inserts an attenuator in the receive direction of a mobile telephone, depending on its transmit level. If the echo suppressor is turned on in cases where there is loud extraneous noise, it is conceivable that the receive signal may be further dampened. This could adversely affect the clarity of the call.

In the "inactive" mode, the receive direction of the mobile telephone is not attenuated when the phone has a high transmit level. In the case of analog trunk switching and loud environments, this setting can offer improved clarity of the trunk station at the mobile telephone.

Echo Canceller

The Echo Canceller (EC) eliminates unwanted signal echoes caused by a 4/2-wire conversion on the land line. If the Echo Canceller is activated without an echo, errors may occur, since the Echo Canceller attempts to adapt to a non-existent echo.

In the "Inactive" mode, the activation of this parameter is prevented, and the Echo Canceller is always off.

Artificial Echo

The Artificial Echo Path (AE) echoes back an attenuated voice signal (24dB) from the land line to the remote subscriber. This may be needed in the case of an international connection, for example, to provide an inserted echo canceller with a certain preload.

In the "Inactive" mode, the activation of this parameter is prevented, and the Artificial Echo is always off.

PP Deviation Control

Echoes often occur when VoIP calls are made using DECT handsets.The "PP Deviation Control" function can be activated to suppress/minimize these echoes. This function affects all DECT handsets connected to the HiPath 3000 communications systems. The activation or deactivation only takes affect for a handset when it is turned off and turned back on.

The function can be used with Gigaset S3 professional, Gigaset SL3 professional, Gigaset S4 professional and newer handsets.

In "Deactivate" mode echo suppression does not work and echoes can occur when VoIP calls are made using DECT handsets. By default the function is deactivated.
