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.

System Features ! The DX-408 and DX-408I are both digital key systems offering a simple and compact

design. ! The DX-408 and DX-408i systems support Plug & Play functionality and are easy to install. ! The DX-408 and DX-408i systems support a Door Phone Interface Module (DPIM)

connection allowing connection of a door-phone. ! Both DX-408 and DX-408i digital key systems accommodate 8 station circuits. ! 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 daughter boards.

Chapter 2

DX-408/DX-408i Digital Key System Installation

Terminating Resistors for DX-408i Trunks Note that 100 Ω terminating resistors must be used for ISDN connections. These must be placed across each of the send and receive pairs. Note that for the second BRI channel 100 Ω resistors are located on the 2BRI board and are able to be switched in and out (refer to S101). These are placed on the second channel in order to provide 100 Ω terminations when the channel is used as 2 ISDN extensions. These terminations are required for ISDN extensions. These resistors should be switched across the pairs for the second BRI channel when used as ISDN Trunks; however, it is necessary to provide external terminating resistors for the first BRI channel. The position of the switch settings in the ON setting (ie. terminating resistors switched across the pairs) is clearly marked on the BRI card.

2-17

MPD/PRS Selection and Installation

This feature is for the DX-408 system only.

The DX-408 digital key system has four analogue trunk interface lines. Each of these interfaces can be configured for either 12-KHz Metering Pulse Detection (MPD) or Polarity Reversal Detection (PRS) by installing MPD or PRS Hybrids respectively. For MPD functionality, insert an MPD Hybrid IC into the socket of each trunk requiring MPD detection. The ports are set up for MPD use and no other hardware changes are required. Trunk Port No.

For PRS functionality, insert a PRS Hybrid IC into the socket of each trunk requiring PRS detection. Because the ports are set up for MPD operation it is necessary to solder a short circuit across the capacitors to provide PRS functionality. For example, if a PRS module is used in Port 2, a short circuit would need to be soldered across C202 and another short circuit would need to be soldered across C203 to provide a direct DC path to the PRS module in socket P201.

Chapter 3 Additional Equipment Connection Connecting Additional Equipment Music-on-Hold/Background Music You can select an internal music source or an external music source for Music on Hold or Background Music by moving a jumper within the DX-408/DX-408i digital key system. Only one source is available: internal music or external music, not both. Various sources such as a CD player, tape player or radio can be used as the external music source. The DX-408/DX-408i digital key system enables programming of the music source by trunk or extension when a call is placed ‘on-hold’. When the hold key of the DX keyset is pressed, the system sends either silence (none), an internally generated tone or the chosen external music source to a trunk or a station (trunk: MMC 408, station: MMC309). In addition, a DX keyset can have an external music source or an internal music source as background music (MMC 308). To set the system up for an external music source the following steps should be followed: 1. Remove the side and front covers from the system. A small jumper (MOH) is provided at the lower right side of the baseboard. You can select an internal (INT) music source or an external (EXT) music source by moving this jumper. 2. The jumper is set to internal tones [INT] by default. To use an external music, set the jumper to [EXT].
