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

SERVICE.

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 FSK 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 > BATT MODE

Configures the on-hook battery voltage. For most IAD installs, the FXS loop is short with 6 to 7 V present on tip / ring. To reduce power dissipated during off-hook conditions, the battery is lowered for short loop lengths. When set to AUTO SWITCH, the IAD uses a higher on-hook battery voltage (48-52 V). When off-hook, it automatically switches to low battery (24-26 V) to minimize power dissipation. When set to LOW BATTERY mode, the higher battery is not used and the voltage is a constant 26 V even while on-hook. The tip/ring voltage is reduced to 26 V when using the LOW BATTERY mode.

INTERFACES (FXS) > CONFIG > FWD DISC TIMER

Specifies the interval of battery removal during a forward disconnect state. Choices are FOLLOW SWITCH (default), 500MS, 750MS, 1000MS, and 2000MS. When using ATM mode, there is an additional choice of IGNORE SWITCH. If the timer is set to FOLLOW SWITCH, the Total Access 6XX will follow the switch at all times; this is normal operation. If a time period has been selected, the Total Access 6XX will remove battery for the specified time period OR as long as the switch requests battery removal, whichever is longer. For example, if the timer expires but the switch continues to request battery removal, the Total Access 6XX will follow the switch and continue to remove battery. For ATM mode, if the timer is set to IGNORE SWITCH, the IAD will never remove battery.

INTERFACES (FXS) > CONFIG > TANDEM

Sets 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.
