| Digital Access System K5302 DASY Features & Benefits Digital Multiplexer to Concentrate PCM Signaling Timeslots Duplication of Timeslots Possible Supports E1 and DS1 Can be Used and Configured Stand Alone Powerful Application to Control Several DASYs Available (Directly via RS-232 or Remotely via Modem or LAN IEEE 803.2) Clock Supply: Internal, External, PCM Link Designed to Enhance the Capabilities of Protocol Testers Support of Time-synchronized Couplings - Allows Coupling of Logical Links on Gb Interface in GPRS Networks Functional Description The K5302 DASY (Digital Access System) is a multiplexer for E1 and DS1 PCM lines. It consists of a mainframe, a control unit (DRC) with display, a power supply and a number of input and output boards. DASY's main function is to couple single timeslots or PCM streams from an input board to one or more output boards. With the latest Firm- and Software the DASY also supports the coupling of groups of timeslots, which will have exactly the same delay when coupled through the DASY. The K5302 mainframe offers 13 slots to be used by input (DDM) or output (DDA) boards. Any combination of boards is possible, however, at least 1 input and 1 output board are required. As each DDM module can handle up to 8 bi-directional PCM lines (either E1 or DS1), the configuration with 12 DDM boards and 1 DDA board would offer a maximum of 96 incoming PCM lines to be connected to the DASY. The remaining DDA board would offer 4 Tx/Tx (8 Rx/Tx respectively) PCM lines. Each of the 2076 input timeslots (96*31, TS 0 to be handled separately) can be coupled to any of the output timeslots. In order to increase the overall capacity of the system, several DASYs may be cascaded. Applications Provide Protocol Testers with Flexible and Convenient Access to Test Environment with Many Links to be Analyzed Concentrate PCM Signaling Timeslots to Enhance Capabilities of Protocol Testers Duplicate Signaling Timeslots/PCM Links to Make the Same Signaling Available for Several Users 1 Protocol Analyzers * www.tektronix.com/signaling Digital Access System K5302 DASY Fields of Application The K5302 has been designed for various purposes: To provide protocol testers with flexible and convenient access to a test environment with a huge number of links to be analyzed Testing under lab conditions often means analyzing different interfaces. The configurations and thus the cabling often change. After connecting all possible PCM links to the multiplexer, DASY offers an easy way to couple the appropriate input links to the output. To concentrate PCM signaling timeslots in order to enhance capabilities of protocol testers such as the K1205 It is not unusual for certain PCM links to be of interest to different users working with different analyzers. Connecting a number of protocol testers to a PCM link may have an impact (due to impedance reasons) on this link. As the DASY offers a convenient way to duplicate single timeslots or even PCM links, it will make the same link available for several users without degrading the performance of the PCM links. In order to avoid operating errors when setting couplings, a 4 digit PIN can be assigned to each output connector. If the password protection is turned on, users can only set/reset couplings on output connectors they have logged into before. To control the configuration of PINs, the user must have a Master PIN. Couplings may be stored in an EEPROM and will then automatically be restored after a power outage. Modes of Operation With DASY Remote Control SW - If more frequent changes of the coupling matrix are required, the remote control application, which comes with the DASY, should be used. This application runs under Windows NT/95/ 98/Me/2000/XP and provides an easy to use interface. The PC running this application can be connected via RS-232 and/or LAN (IEEE 802.3, RJ-45) interface to the DASY. Besides using a direct serial connection via RS-232 (data rates 1,200 to 19,200 b/s), it is possible to connect a modem to the DASY and dial in remotely. With the LAN interface it is even possible to control the DASY using the Internet as a transport media From a User Application - Tektronix offers a The number of physical PCM interfaces of a protocol tester is usually limited. On the other hand, it is quite common that only very few (even just one) timeslots of a PCM link are used for signaling purposes. By multiplexing single timeslots of several links to one output PCM link DASY offers a solution to solve this contradiction. To duplicate signaling timeslots/PCM links in order to make the same signaling available for several users Control C Library for Windows NT/95/98/ Me/2000/XP, which provides a well defined API (application programming interface). It enables a user to control the DASY from a user application. This library supports the serial interface as well as the LAN interface and gives full access to DASY's functionality. By using this API, it is possible to set up to 4 couplings per second. DASY can handle up to 10 TCP/IP connections simultaneously DASY can be operated in 3 modes: Stand Alone - The complete set of features of the DASY can be used without any additional hardware or software*1. A 20*4 character LCD provides an intuitive menu to operate DASY with only 5 keys. This mode of operation should be used for quasi-static configurations *1 Grouped Couplings can only be set up, modified, and deleted using the Remote Control Software. 2 Protocol Analyzers * www.tektronix.com/signaling Digital Access System K5302 DASY DASY Remote Control Application The easiest way to operate the DASY is the remote control application. This software is able to control an unlimited number of DASYs regardless whether the units are connected directly via a serial cable, via a modem or a LAN connection (see Figure 1). A Microsoft Explorer-like tree structure offers an easy way to navigate through the different DASYs and their input and output boards. The software automatically detects the hardware and firmware versions of the DASY connected to it, and can thus also control elder units. This software offers the following functions: Easy setup of couplings Couplings are displayed in a tabular format Figure 1. DASY Overview. Each coupling can be assigned a specific name which will be stored (see Figure 2) The complete configuration can be stored and later retrieved Figure 2. Add a new coupling.

Working with the coupling scheduler. Figure 4. Display of DASY receiver alarms. 4 Protocol Analyzers * www.tektronix.com/signaling Digital Access System K5302 DASY Application Examples Figure 6 shows a quite common configuration: Several PCM links are connected to the DASY input. DASY extracts the SS7 signaling channels (TS 16) from these links and concentrates them into a single PCM link. This link is duplicated and connected to the input of 2 K1205 Protocol Testers. The couplings of the DASY are set up on a separate PC that is connected to the DASY via LAN. If the DASY is not at the same site as the Protocol Testers, leased lines can be used to provide the connection between the units as illustrated in Figure 7. While protocol testers are usually fed with a PCM link, which contains a (Tx-) signal in both directions, the leased line equipment usually needs a normal Rx/Tx pair on both ends of the leased line. The DASY output (DDA) boards provide 2 Rx/Tx pairs per connector (8 in total) and can be placed on both ends of the leased line. The incoming links at the protocol tester site can be coupled to any other DDA board in order to provide the protocol tester with the normal Tx/Tx link. Of course there can be other incoming links connected to the input boards of the DASY. The couplings of the DASY can be configured via a modem connection. Note: The back direction of the leased line (tester => remote site) is not used to transfer any signaling data but is needed to run the leased line properly. Figure 5.
