DX-408/DX-408i
Digital Key System
Overview
The DX-408/DX-408i digital key system is designed for the small office/home office. Both
DX-408/DX-408i digital Key systems utilise a baseboard to provide 8 station circuits (4
circuits for digital keysets and 4 circuits for analogue telephones (SLT’s)) and 4 trunk circuits.
The DX-408 digital key system accommodates 4 analogue trunk lines and the DX-408i digital
key system accommodates 2 BRI lines (4 Channels). In addition, one of the BRI ports (2
Channels) of the DX-408i system can be substituted for ISDN extensions.

The DX-408 digital key system accommodates 4 analogue trunk lines. The DX-408i digital
key system can provide 4 digital trunk channels using both ISDN interfaces. However, the
second BRI port can be configured as a Network Termination (NT) rather than 2 digital
trunks. That is, it becomes an extension port to provide access to ISDN terminal equipment
attached to the DX408I as extension equipment. A typical application would be to connect
a router to this port – this could be used to dial out to the ISDN network via the DX408i.
The DX-408/DX-408i digital key systems do not support AOMs or keyset
daughter boards.
