Chapter 3: Terminal Menu Operation and Structure

ISDN/FEBEs

Read security: 5

This contains the number of Far-End-Block-Errors (FEBEs) that have been de- tected by the ISDN circuitry on the other end of the link. Continuous errors can indicate a line problem, but a burst at one time is normal.

WAN/POTS

Write security: 2; Read security: 5

POTS parameters are under this menu. They appear only under the Express L128T version.

POTS/POTS Assignment

Write security: 2; Read security: 5

The Express L128T can assign the POTS interface either POTS1 to LDN 1 and POTS2 to LDN 2 (def), or POTS2 to LDN 1 and POTS1 to LDN 2 . Once as- signed, all incoming and outgoing calls on a particular port are placed to/from the assigned number.

POTS/NI-1 Conference FI

Write security: 2; Read security: 5

National ISDN Conference feature indication number is placed here. Most COs use the default of 60.

POTS/NI-1 Transfer FI

Write security: 2; Read security: 5

National ISDN Transfer feature indication number is placed here. Most COs use the default of 61.

POTS/Speech Calltype Routing

Write security: 2; Read security: 5

This allows the Express L128T to treat incoming calls as “data over speech” when selected as LAN. Otherwise, when set to POTS (def), incoming speech calls are sent to the POTS when the destination number is the same as the POTS assignment.
