Is the GradeShift UDL dual-path capable?
Yes. The GradeShift UDL supports a secondary path in addition to the primary GSM path. The following Gradeshift UDL variants are available:
- GradeShift UDL GSM only.
- GradeShift UDL GSM + LAN.
- GradeShift UDL GSM + PSTN (discontinued due to All IP & the Copper Switch-Off).
Important Note: The GradeShift UDL only supports one secondary path at a time. I.e. It cannot support GSM + LAN + PSTN. It can only support GSM + LAN or GSM + PSTN.
