  • Page 2 IMPORTANT INFORMATION ABOUT LEAD FREE, (PbF), SOLDERING If lead free solder was used in the manufacture of this product the printed circuit boards will be marked PbF, Standard laded, (Pb), solder can be used as usual on boards without the PbF mark. When this mark does appear please read and follow the special instructions described in this manual on the use of PbF and how it might be permissible to use Pb solder during service and repair work.
  • Page 3 We will use PbF solder when discussing the lead free solder used in our manufacturing process which is made from Tin, (Sn), Silver, (Ag), and Copper, (Cu). This model, and others like it, manufactured using lead free solder will have PbF stamped on the PCB.
  • Page 4 1.2. HOW TO RECOGNIZE THAT Pb FREE SOLDER IS USED 2. FOR SERVICE TECHNICIANS ICs and LSIs are vulnerable to static electricity. When repairing, the following precautions will help prevent recurring malfunctions. 1. Cover the plastic part's boxes with aluminum foil. 2.

  • Page 19 7.1.3. Interrupt Fig.5.1 External interrupt image Note: - nHALT signal is consistent with the existing PBX and performs polling by I/O port. However, when the CPU (IC1) goes to Sleep Mode at HALT, the CPU (IC1) is enabled for interruption on release nHALT and return from Sleep Mode.
  • Page 20 (The configuration with the interruption processing is to give a consistency with the existing PBX.) - Since the nRxMF signal of the T1-IC (IC302) occurs in periodic frame timing, the polling by i/o port is impossible. 7.2. LINE INTERFACE FUNCTION 7.2.1.
  • Page 21 7.2.2. Line Interface Loopback This card has a relay for loopback test on the primary side of the line to cut and divide into the line failure or the PBX's own failure, when there is a defect in operation. Fig.5.3 Outline diagram of the line interface 7.3.
  • Page 22 McBSP(Multi-Channel Buffered Serial Port) and the control system is connected with the CPU (IC1) local bus through the HPI-8 (Host Port Interface) of the DSP (IC303). See the DSP (IC303) Data Sheet for the detailed specifications of the McBSP and the HPI-8. Fig.
  • Page 23 7.4. LOCAL HIGHWAY INTERFACE FUNCTION This card has the local highway in the speed of 2.048Mbps and local TSW (ASIC (IC2) internal module) to switch from the call channel (Bch) extracted from T1 line by the T1-IC (IC302), to H.100 interface. As the switching function inside the DSP (IC303) is used for the in-band signaling detection by the DSP (IC303), there is no assignment directly on the local highway map, but the operation is synchronized with the local highway in timing.

The +15V power supply generates +5V, +3.3V and +1.8V via DC/DC converter, and they are fed as the power of circuit in the card. The +40V power supply is not used due to no feeding to the line.
