KX-TDA Panasonic Telephone exchange Hardware: A, KX-TDA board: 1) IP-GW4 (KX-TDA0480): voice gateway board 2) CTI-LINK (KX-TDA0140): lan interface card 3) CS-INF (KX-TDA0144): 8 cell station interface circuit board 4) OPB3 (KX-TDA0190): optional 3-slot basic card. ① MSG4 (KX-TDA0191): 4-channel information card provides 4-channel 64 segment voice, which is a DISA board with automatic computer operator function. ② ECH04: Based on ISDN, external calls no longer generate echo. ③ EI04: Fire alarm and other sensors may be directly connected to TDA system. 5) PRI23: PRI network has 23 channels. B. KX-TDA Panasonic Switch Improved hardware structure: 1) Distributed control: it eliminates the disadvantages of traditional central control. The new TDA system is based on the distributed control structure of various function boards. This control structure reduces the processing tasks of MPR (CPU) and improves the reliability and stability of the system. 2) Cancel the TSW board card, and the bell flow control is distributed on each function board, which solves the problem that the extension does not ring because of insufficient bell flow. 3) The hardware upgrade is simple, and the hardware upgrade based on SD card is simple and fast. It can be upgraded remotely. 4) Improved power supply system: TDA system has a built-in power adapter, which can be customized from the perspective of users with different configurations. 5) The standard 190 inch chassis design can directly place the system into the 19 inch cabinet. 6) Programming using USB port, simple wiring, fast speed; Software programming can be carried out either on the phone or on a computer. 7) The phone provides USB interface module to realize computer phone integration. 8) DXDP function increases the overall capacity of the system (the number of extension ports is doubled). 76XX can be attached with a 76XX and an SLT. 9) The extension board is downward compatible, and Panasonic has a full range of phones. 10) E1 and PRI boards have BNC and RJ45 interfaces; BRI provides jumper switch for external line of extension, and ISDN extension can be used without cross jumper. 11) The common external line provides an incoming call display board (small board), which can be used as the incoming call display of the common external line. C. New features of the KX-TDA Panasonic switch: 1) CLI service that determines the ringing target based on incoming calls. 2) If the extension is busy, the number of incoming calls from outside lines can be displayed. (Telecom application call waiting function) 3) Call Center (call center function): Hurry up Transfer call VIP call Busy on busy function Wrap up 4) Call forwarding of ICD group. 5) Call proxy groups. Groups can answer incoming calls for each other. 6) Direct selection station directly answers incoming calls. 7) Automatic answering function for external lines. 8) Hidden monitoring. 9) 8 party meeting (3 groups at most, each group includes 4 external lines). 10) Multiple AA service of DISA: (64 layers at most) 11) extension phonebook locking. 12) Call waiting information of ICD group. 13) Call forwarding from ISDN external line to external line, after which the line is automatically released, and does not occupy ISDN external line (the telecommunications office applies for forwarding function) 14) ISDN external line to external line call forwarding, after which the line is automatically released and does not occupy ISDN external line (the telecommunications office applies for transferring function) 15) ISDN extension can join the conference. 16) CCBS: Busy messaging on external lines, ISDN external lines. 17) VPS can send different outgoing languages to different relay groups. 18) VPS time and working mode can be synchronized with the switch. 19) Call between extensions can be restricted. 20) The extension password can be used to limit the remote extension function. 21) Remote control extension function. 22) Built in VOIP voice gateway. 23) VOIP network call can directly display the name and number. 24) After the system is networked, it calls the other end of the network through the network, and the call level limit can be set on the external line of the opposite end. 25) Call proxy group. 26) Quick setting system. 27) The system can automatically configure ISDN external line parameters. 28) MPR (CPU) and LPR (function card) can be upgraded simply, and the wireless base station (CS) can also be upgraded directly through the CS-INF interface card. 29) ISDN external line provides power failure transfer function (transfer to ISDN extension). 30) Select range alarm to E-mail
