Total Access 600 Series System Manual Section 4.2 T1 TDM UIG

INTERFACES (FXS) > CONFIG > TX (dB)

Sets the TX direction level points. This signal will change the volume of the voice. TX (dB) is the signal

that is transmitted out the T1, with 0 dB being the strongest. If the volume is too loud across the T1, this

number should be increased. A higher number indicates more attenuation which equals lower volume. The

value entered must be less than 10 dB. Default is

6.0 dB.

INTERFACES (FXS) > CONFIG > RX (dB)

Sets the RX direction level points. This signal will change the volume of the voice. A higher number

indicates more attenuation which equals lower volume. The value entered must be less than 10 dB. Default

3.0 dB. 0.0. dB is the maximum signal.

INTERFACES (FXS) > CONFIG > SVC MODE

Indicates whether the module is IN SERVICE or OUT OF SVC. This does not indicate whether the port has

been mapped. For proper operation, the port must be mapped using the

DS0 MAPS menu. Default is IN

ERVICE.

INTERFACES (FXS) > CONFIG > LINE Z

Sets the line impedance. Choices are 600 OHMS, 900 OHMS, 600 OHMS + 2.16µF, 900 OHMS + 2.16µF, and

AUTO. The line impedance of each port is based on the size of the network. Default is 600 OHMS.

INTERFACES (FXS) > CONFIG > MSG IND

This is better referred to as On-Hook Message Waiting. When this is set to ENABLE, talk path is always

open, even in On-Hook conditions, in order for these FXS message tones to pass through. Default is

DISABLE. Enabling on-hook message waiting will allow message lamp usage but will cause a lower

on-hook voltage. Disabling this feature will allow higher on-hook voltage but will not allow on-hook

messaging other than caller ID.

INTERFACES (FXS) > CONFIG > TANDEM

Set the port to use E&M signaling on the T-Span and either loop start or ground start supervision on the

analog 2-wire interface. To access submenus for this item, use the arrow keys to scroll to the

TANDEM

column for the corresponding module, and then press <Enter>.

INTERFACES (FXS) > CONFIG > TANDEM > CONVERSION MODE

Sets the port to either LOOP START or GROUND START mode. Default is LOOP START.

INTERFACES (FXS) > CONFIG > TANDEM > SUPERVISION

Sets the supervision method used to either IMMEDIATE or WINK. Default is IMMEDIATE.

INTERFACES (FXS) > CONFIG > TANDEM > DIAL TONE

(This option is only available for the Total Access 612/616/624.)

Used to enable or disable the on-board dial tone generation. Dial Tone is supplied for 5 sec, then it drops. It

cannot be broken when dialing digits. Default is

DISABLE.
