Digital Loop Extender

The Digital Loop Extender (DTIBL) is an optional item that is used to extend the distance that
a single digital keyset can be located from the KSU. The maximum recommended loop length
of 1000' from the KSU is extended to approximately 3000' with the use of the DTIBL.
The distances shown in the following illustration are based on using the full 3000' of range
provided by the DTIBL. The location of an available power source may cause the distances to
vary. The distance between the KSU and the DTIBL should always be greater than the distance
between the DTIBL and the keyset.
It is recommended that the DTIBL only be used indoors. If out of building use is required, the
installer is responsible for providing the necessary surge and environmental protection.
The DTIBL includes a power adapter.
DTIBL Installation Procedure:
1. Connect a 2-wire line cord from the extension block of the KSU to the plug labeled "KSU"
on the DTIBL.
2. Connect a 2-wire line cord from the plug labeled "KTU" on the DTIBL to the plug on the
base of the keyset.
3. Plug the appropriate cord from the Power Adapter into the DTIBL and the power cord
into a power source.
