0x01E1 Fax Compatibility Mode

Use this TLV to determine the VDAC-ONE card’s T.38 Fax Relay Compatibility Mode:

• Backward Compatible mode

or

• Interoperability mode.

These modes are incompatible. You can choose one mode or the other, but not both. The Backward Compatible mode is interoperable with the fax relay mode on the previously-released software. The Interoperability Mode is primarily used to interoperate with third party T.38 fax relay.

This TLV can be configured only before the call is established. It cannot be configured during an active call. This TLV does not apply to the IP Network Interface Series 2 card.
