FUNCTIONAL DESCRIPTION Purpose and Main Features The DV-MUX3 is a versatile adaptive time division multiplexer (TDM) for voice, fax, and data.
CHAPTER 1 - INTRODUCTION ° The other non-adaptive mode provides the user with access to all the link bandwidth that is not used by the voice channel. In this mode, the data channel can serve data terminal equipment capable of operation in accordance with the rate of the clock signals provided by the DV-MUX3, including operation at data rates which are not necessarily based on the n × 75 bps scheme.
FUNCTIONAL DESCRIPTION The FXO and FXS options are usually operated in a link, with the FXO interface at the PABX side, and the FXS interface on the subscriber’s side. In addition, two FXS interfaces can also be operated in a link, to provide PLAR (Private Line with Auto-Ring) telephone service. The E&M interface is usually used to connect trunk lines of two PABXs. In this case, two E&M interfaces are operated in a link.
CHAPTER 1 - INTRODUCTION The following control lines are used on the main link interface: • The RTS line, which is asserted as long as the DV-MUX3 is powered. • The DTR and RI lines, used only in the dial-up mode. Dial-up Mode The dial-up mode allows the DV-MUX3 to operate over the Public Switched Telephone Network (PSTN), using dial-up modems to transmit the main link data over standard PSTN lines. The dial-up mode is available only when the main link interface is V.35 or RS-232.
FUNCTIONAL DESCRIPTION ° For a voice channel equipped with E&M interface, the channel control signal generated by that channel indicates detection of an M signal. The control signal received by that channel (E signal) indicates the reception of subscriber off-hook at the remote FXS module or detection of the M signal at the remote E&M module.
CHAPTER 1 - INTRODUCTION • Front panel indicators show main link synchronization status, transmit and receive activity on any desired channel, and activation of a test loop. In addition, the front panel indicators also indicate failures in the power-up selftest, configuration errors, and fault conditions related to the main link clock signals. General Features 1-6 The DV-MUX3 can be ordered for AC operation (100, 115, or 230 VAC) or for -48 VDC operation, and has very low power consumption.
TYPICAL APPLICATIONS AND SYSTEM DESIGN CONSIDERATIONS 1-2. TYPICAL APPLICATIONS AND SYSTEM DESIGN CONSIDERATIONS Typical Applications This section provides examples of applications that use the specific capabilities of the DV-MUX3. Typical DV-MUX3 Application in an SNA Link Figure 1-1 shows a typical application for a DV-MUX3. This application shows how an organization can use the DV-MUX3 to connect privileged telephone subscribers located in another city, e.g.
CHAPTER 1 - INTRODUCTION • The second voice channel of the DV-MUX3 is used for PLAR service, and is connected directly to the subscriber’s telephone set. This voice channel uses an FXS interface. • At the branch office, the two local subscriber sets are connected to the two voice channels of the DV-MUX3. These voice channels use the FXS interface. The first voice channel (connected at the main office to a subscriber line of the PBX) is used for voice/fax transmission.
TYPICAL APPLICATIONS AND SYSTEM DESIGN CONSIDERATIONS • For a voice channel with FXO interface: the detection of incoming ringing at the voice channel interface. • For a voice channel with E&M interface: the detection of an active M signal. Figure 1-2.
CHAPTER 1 - INTRODUCTION This symmetry reflects the way voice channels are used (either side can initiate a call to the other side). • Valid connection requests originating from the data channel can be made only by the slave DV-MUX3, because the DV-MUX3 dial-up mode is designed to operate asymmetrically with respect to the data channel. This means that a request for connecting the link to the other DV-MUX3 can be made only by the slave DV-MUX3.
TYPICAL APPLICATIONS AND SYSTEM DESIGN CONSIDERATIONS Control over the Main Link Modems The control of the dial-up modems serving the main link is made by means of the DTR line of the DV-MUX3 main link interface. Assuming that the modems were configured as explained above, the sequence for setting up and for disconnecting the link between two DV-MUX3 units is as follows: • The link is in the disconnected state when no user traffic is present.

TYPICAL APPLICATIONS AND SYSTEM DESIGN CONSIDERATIONS System Timing Considerations This section explains the timing modes and clock rates available for the main link of the DV-MUX3, and for its data and voice channels. Main Link Timing The main link transmit and receive paths of the DV-MUX3 require external receive and transmit clock signals derived from the network clock. The transmit and receive clock must be derived from the same source.

This board contains most of the DV-MUX3 circuits. • Voice channels module. In accordance with your order, this module can include one or two voice channels. • Voice channel interface modules. Three types of voice channel interface boards are available: ° DV-MUX3-FXO for FXO interface. ° DV-MUX3-FXS for FXS interface.
CHAPTER 2 - INSTALLATION Opening DV-MUX3 Case The DV-MUX3 jumpers are located on its boards. The boards are attached to the rear panel. To reach the internal jumpers: • Disconnect all the cables connected to the DV-MUX3. • Unscrew the two large captive screws located on the rear panel. • Carefully pull the rear panel out. The internal boards will slide out together with the panel. The DV-MUX3 has several tall components which barely clear the top cover: make sure you do not damage these components.
DV-MUX3 CONFIGURATION INFORMATION Main Board Jumpers The user-selectable jumpers located on the main board of the DV-MUX3 are identified in figure 2-2. In addition to the jumpers identified in figure 2-2, the main board includes additional factory-set jumpers which must not be moved. Figure 2-2. DV-MUX3, Identification of Main Board Jumpers MODE Selection Jumper, J2 This jumper selects the DV-MUX3 bandwidth allocation mode, and its configuration mode.
CHAPTER 2 - INSTALLATION main link bandwidth is always fully utilized, however not all types of user equipment can support the dynamic changes in clock rate that occur in this mode. See Table 1-1 for the available data rates. N/ADPT1 The DV-MUX3 operates as a master, and uses the non-adaptive 1 allocation mode. In this mode, the DV-MUX3 determines the data rate of the data channel as in the adaptive mode, except that the bandwidth required by the voice channel is permanently allocated.
DV-MUX3 CONFIGURATION INFORMATION DTR Jumper, J11 This jumper is used to enable the dial-up mode. The dial-up mode can be enabled only when the DV-MUX3 main link interface uses the RS-232 interface. For other interfaces, the dial-up mode is not available, irrespective of the setting of this jumper. The jumper has two positions: CNTL When the RS-232 interface is selected, the dial-up mode is enabled.
CHAPTER 2 - INSTALLATION Figure 2-3. Voice Channels Module Switches VOICE2 Enable Switch, SW5 On DV-MUX3 units equipped with two voice channels, this switch allows the user to disable voice channel 2. By disabling voice channel 2, the bandwidth available to the data channel is increased. The switch has two positions: • DIS - voice channel 2 is disabled. • EN - voice channel 2 is enabled. The default setting is EN.
DV-MUX3 CONFIGURATION INFORMATION Level Adjustment Switches, SW1, SW2, SW3, SW4 These switches are used to select the nominal input and output levels of the voice channels: • SW1 selects the nominal output level of the voice channel 1 receive path. • SW2 selects the nominal input level of the voice channel 1 transmit path. • SW3 selects the nominal output level of the voice channel 2 receive path. • SW4 selects the nominal input level of the voice channel 2 transmit path.
CHAPTER 2 - INSTALLATION Voice Channel Interface Modules Only the DV-MUX3-E&M voice channel interface board requires internal settings that are used to select the signaling mode and the interface type, 2W or 4W. Figure 2-5 identifies the position of these switches. Figure 2-5. DV-MUX3-E&M, Internal Settings E&M Signaling Mode Selection The DV-MUX3-E&M module supports five E&M signaling modes: RS-464 Type I, II, III and Type V, and British Telecom SSDC5.
