Features & Benefits

Customized Signaling Analyses of CCS#7, GSM, CDMA, ISDN D-Channel, X.25, V5.1, V5.2, PHI
  • Monitoring of up to Eight Signaling Channels on Four PCM Links
  • For PCM30, PCM24 and V./X. (V.24, V.35, X.21)
  • Simple Operation as with a PC with MS-DOS and Windows
  • Programmed Applications for Fast Problem Analysis

Applications

  • The Protocol Tester K1103 has been developed for network supervision and network analysis of CCS#7, GSM, CDMA, ISDN D-channel, X.25 and V5.x protocols. A maximum of four different PCM links (T1/S2M) or V./X. links with up to eight signaling links (64 kbit/s, 56 kbit/s, 16 kbit/s) can be supervised simultaneously.
  • The Protocol Tester K1103 features a Windows 3.11 based user interface.
  • Analysis of the different layers of the communications protocols can be performed online or offline. The auto-restart mechanism enables long-term measurements to be carried out, e.g., following a power failure. User-specific prepared measurement tools for supporting measurements in the field are also supplied. Automatic evaluation of these measurements, alphanumerically and/or in graphics form, is performed by a special statistics program package. A storage capacity of 2.5 MB in the main memory and 500 MB on the hard disk is available for recording the measurement data. A floppy disk drive can additionally be used for recording measured data.

Design

The Protocol Tester K1103 consists of a PC card with 8–MB RAM, a 540–MB hard disk and a 1.44–MB floppy disk. A TFT color display, which can be read without impairment even under bad lighting conditions, is used as the display. Graphics control is by means of a VGA card.

The keyboard can, if necessary, be removed from the tester in order to enable more comfortable working. MS-DOS 6.2 is used as the operating system.

Line activities are displayed on LEDs on the front of the instrument.

The actual measuring hardware employs obsolescence-proof technology. The processing power, for example, is increased by using transputers.

A serial interface for remote control, a printer interface (serial/parallel), as well as a VGA interface for external monitors, are available.

Special Features

The K1103 features particularly easy handling. This comprises:

  • Putting the test hardware and software into service
  • Connecting to the PCM links (S2M/T1) or V./X. links
  • Protocol detection
  • Link selection

The test modules can be inserted in the Protocol Tester K1103 simply by plugging them in. No further hardware settings or reconfiguration is required as this is executed at a keystroke by the testing software provided. When the K1103 is connected to the PCM links, the autoconfiguration function determines the signaling channel search and the framing search. No preliminary manual settings are required. As soon as the autoconfiguration is completed, all the active signaling channels are available and can be displayed simultaneously or separately on the screen. Again a keystroke is all that is needed to select a particular link and thus reduce the screen display to the required data.

The Protocol Tester K1103 also has a wide and impressive range of powerful display formats. Message components from any source are decoded online and to the maximum possible depth if required. All the important message parts are output not only in binary or hexadecimal but also in mnemonic form (online and offline in parallel). Special search functions permit selective tracing of any desired message parts, e.g., an IMSI/TMSI (International/Temporary Mobile Subscriber Identification).

Description of Application Options for CCS#7

Analysis of signaling over a linkset between two switching systems
Thumbnail

Fig. 2 Analysis of a linkset with foursignaling links.

Interexchange signaling with CCS#7 is not performed via one signaling link during real operation, since failure of this link would result in failure of up to 1000 traffic channels. A number of signaling links - 2 to 4 depending on traffic - are therefore combined to form a so-called linkset. Since the load-sharing mechanism in the switching system does not allow the signaling link for a particular call to be predicted within a signaling linkset, all signaling links between two switching systems must be supervised simultaneously.

Analysis of signaling on two linksets

Fig. 3 Analysis of two linksets each with two signaling links.

In order to test the operability, behavior and switching times of a switching system, its input and output linksets must be analyzed simultaneously. Since, as a rule, 2 signaling links are combined in a linkset, 4 signaling links must be supervised simultaneously.

Fig. 7 Typical GSM analysis.

It is necessary to view several of these interfaces at the same point in time in order to assess the interoperation of the network components. One example is shown in Fig. 7 where the K1103 analyzes the signaling from the base station via the base station controller and the mobile switching center into the public telephone network. In parallel with this, a check is made as to whether the mobile telephone of the calling subscriber is entered in the HLR, i.e., whether the MSC executes this request. Another example for the use of the K1103 is to test handover procedures.

It is possible to test any combination of up to four PCM links with up to eight signaling links simultaneously.

Table 1. Protocol stacks for the various GSM interfaces are available (GSM Phase 1, Phase 2, Phase 2+, PCS 1900 and CDMA). The protocols for GSM Phase 2 and Phase 2+ are for 900 MHz and 1800 MHz available.

For a number of tests on the A- and Abis- interface, it is intended to provide special testing programs, e.g., to facilitate or automate:

  • Call tracing (incl. handover)
  • Mobile terminating call (MTC)
