Chapter 1 Introduction QUAD FXS VOICE MODULE OVERVIEW The Quad FXS Voice Module (see Figure 1-1) is for use in the Total Access 750/850/1500 (TA 750/850/1500) platforms to provide analog voice extension. The Quad FXS resides in the TA chassis that is next to or close to the customer’s telephone and is usually located on the customer’s premises.
Chapter 1. Introduction Functional Description The Quad FXS Voice Module installs in any available option slot in the TA 850 chassis. You can view the status of the module itself, as well as the circuits to which it interfaces, from the TA 850 front panel. Additional status information is available via the terminal menus, accessible through either a VT-100 terminal connected to the TA 850 control port or via a Telnet session established through the Base Unit’s Ethernet port.

Chapter 2. Installation Instructions for Installing the Quad FXSVoice Module (Continued) Step Action 5 Connect the cables to the associated device(s). 6 Complete installation of remaining modules and Base Unit as specified in the Installation chapter of the TA 850 User Manual. WIRING A single 50-pin male amphenol connector on the rear of the TA 850 chassis provides the interconnect wiring for the four analog circuits on each access module. Figure 2-1 shows the pinout connection.
Chapter 3 Operation OVERVIEW The Quad FXS Voice Module goes operational upon insertion into an active TA 750/850/1500 chassis. Once the unit is inserted, it must be mapped to a network interface for proper operation. Refer to the TA 850 User Manual Channel Bank chapter (DS0 mapping section) for information.
Chapter 3. Operation METHODS OF OPERATION You can control and configure the Quad FXS Voice Module from the following sources: • The terminal menus, allowing detailed configuration, status, and diagnostics • SNMP, primarily for reporting alarm conditions and system status The remainder of this chapter describes the menu items presented when managing the Quad FXS Voice Module via the terminal menu.
Chapter 3. Operation QUAD FXS VOICE MODULE MENU OPTIONS Figure 3-1 shows the menu options available for the Quad FXS Voice Module. The following sections describe these options. Figure 3-1. Quad FXS Voice Module Menu Options PRT Identifies the port involved. MODE Options are given below. LOOP START Sets the port to use FXS loop start signalling on the T-span and loop start supervision on the analog 2-wire interface.
Chapter 3. Operation TX (DB) Sets the Tx direction transmit level points. The transmission level is indicated in dBm. Range is from 0 to 9.9 dBm. Default is 6.0. RX (DB) Sets the Rx direction transmit level points. The transmission level is indicated in dBm. Range is from 0 to 9.9 dBm. Default is 3.0. SVC MODE Indicates whether the module is IN SERVICE or OUT OF SVC. This does not indicate whether the port has been mapped. For proper operation, the port must be mapped using the DS0 MAPS menu.
Chapter 3. Operation QUAD FXS VOICE MODULE TEST OPTIONS PRT Identifies the port involved. TEST To initiate a module test, scroll to the TEST column and press Enter. Options are detailed below. DIGITAL LOOPBACK TEST The Digital Loopback Test is used to loop back DS0 data coming from the network for each channel. Received data is latched In on the appropriate receive time slot on the receive bus. This data is then placed on the transmit bus in the unit’s transmit time slot.
Chapter 3. Operation factory settings for all of the module options), while the cursor is over the PRT number (this action restores the factory settings for the port), or while the cursor is over an individual field (this action restores factory settings for the particular field only).
