Setting Cable Length Offset (E1)

Cable length offset is used to optionally align the DECT or radio signals between transceivers. If transceivers are not synchronized, beltpack handover will not happen effectively. This is particularly important if you have overlapping transceiver coverage zones (RF cells) or the beltpacks need to move between coverage zones.

Cable length offset or transceiver sync compensation needs to be set when:

• The difference in total cable length between transceivers is ≥ 1640ft / 500m (this includes both fiber and copper cable runs).

Example

TCVR #1: total cable length = 328ft /100m

TCVR #2: total cable length = 2788ft / 850m

The difference in cable length between transceivers = 2460ft / 750m. Therefore, in this case you must set transceiver cable length on both transceivers. This allows any latency to be calculated and offset by the system.
