Introduction 1-1 1 Introduction
1-2 About this user guide About this user guide This user guide describes the Protocol Analyzer Package (PAP). It covers the installation and operation of the PrimeSwitch 100 Series Integrated Services Digital Network (ISDN) PAP. PAP is available for both Primary Rate and Basic Rate in a number of protocol variations. The PrimeSwitch PAPTS14 is an ISDN Primary Rate monitor conforming to Austel Specification TS14. The PrimeSwitch PAPTS13 is an ISDN Basic Rate monitor conforming to Austel Specification TS13.
Introduction 1-3 Using this guide The guide contains the following sections: Overview describes how PAP processes network traffic. The PAP screen describes the main screen and illustrates how PAP displays messages. Commands describes how to control PAP with function keys and typed commands. Installation describes how to install PAP and connect PAP to a PC. Technical assistance information If there is a problem using the N.E.T. products, call the N.E.T. Technical Assistance Center (TAC) for assistance.
1-4 Overview Overview The PrimeSwitch ISDN Protocol Analyzer Package (PAP) monitors and displays layer 1, layer 2 and layer 3 protocol activity on a PrimeSwitch ISDN interface. PAP uses COM ports on the PC to transfer information to and from a PrimeSwitch ISDN module. PAP can monitor multiple ISDN interfaces on PrimeSwitch 100 Series modules which have more than one (for example, the DTM or QBRM), and can use either COM1, COM2 or BOTH at the same time on the PC.
Introduction 1-5 This default can be overridden from the command line as follows: PAPXXXX REAL forces the PAP software to use conventional memory and will not operate if insufficient conventional memory is available. PAPXXXX VIRTUAL forces the PAP software to use Extended or Expanded memory and will not operate if memory is not available. These overrides should not be used unless problems are experienced with the default.
1-6 Overview Figure 1 shows the relationship between CES, SAPI and TEI. Figure 1: CES, SAPI and TEI 10003137.00 Rev.
Installation 2-1 2 Installation
2-2 Installing PAP Installing PAP PAP can be used to monitor traffic on either a local or a remote PrimeSwitch. Local To monitor local traffic connect the PC to the PrimeSwitch PAP connector, as in the following diagram: PC PAP PrimeSwitch Figure 2: Local connection Remote via ADLM To monitor remote traffic, a V.24 ADLM must be installed in both the local and remote PrimeSwitches. Connect the PAP connector to an ADLM V.24 port on the remote PrimeSwitch, and connect the PC to an ADLM V.
Installation 2-3 Remote via modem You can also use a modem to monitor traffic on remote PrimeSwitches, as shown in Figure 4.
2-4 Connecting PAP to an ISDN interface module Connecting PAP to an ISDN interface module BRMN, BRMT and early IPMN and IPMT You must place the PrimeSwitch PAP Module panel in the slot immediately to the right of the ISDN interface module that you want to monitor, with the connector located at the top. If necessary, rearrange the modules in the PrimeSwitch to clear the slot on the right hand side of the ISDN interface module.
Installation 2-5 Connecting PAP to a PC Connect the PrimeSwitch PAP protection device to a parallel port of the PC. To monitor local traffic: 1 Connect COM1 or COM2 on the PC to the 25-way D type connector on the PrimeSwitch PAP panel using a straight through cable constructed according to Figure 5. 3 2 2 3 3 7 7 5 DB 25 Female (to PC) DB 25 Male (to PAP V.

Installation 2-7 Software installation The PAP software is installed as part of the PrimeSwitch Manager—NCS (Net Center Software) installation process. To install individual versions: 1 Create a directory for the PAP software. Type: MD \PAP 2 Change to this directory. Type: CD \PAP 3 Insert the PAP disk (PM-NCS Disk 3) into the floppy drive and change to the PAP subdirectory. Type: CD A:\PAP 4 Expand the required file. Type: expand A:PAPTS14.EXE expand A:PAPTS13.
2-8 Starting PAP Starting PAP To start the program: 1 Either: • from Program Manager, double-click on the icon; or • from MS-DOS, change to the PAP directory and type one of the following: PAPTS14 PAPTS13 PAPETSI PAPETSIB PAPDASS2 PAPDPNSS To change the COM port or baud rate settings, use the Port and/or Rate commands (see Chapter 4 — Commands). Changes are saved when the program exits and will be used each time the program starts. 10003137.00 Rev.
The PAP screen 3-1 3 The PAP screen
3-2 Screen display Screen display Status line Display window Layer 1 status line Command window Command line Figure 7: Screen display for Primary Rate Access The PAP screen, an example of which is shown in Figure 7, contains the following elements: Status line displays the status of the PrimeSwitch, including operation state, link status, level of layer 2 and layer 3 decoding, and other information. For Basic Rate access, the current CES is displayed at the far right of the status line.
The PAP screen 3-3 The Basic Rate screen differs from the Primary Rate screen in the following ways: • the Call Reference Indicator has two digits, not four; • the current CES indicator is at the far right of the status line; • there is a different set of layer 1 state indicators; • the startup display shows different connection ports.
3-4 Display colors Display colors On a color monitor, traffic is displayed in the following colors: Green Network side, layers 2 and 3. Purple User side, layers 2 and 3. Yellow Layer 1. 10003137.00 Rev.
The PAP screen 3-5 Status line The following diagram is a sample status line with each field numbered. Fields are described in detail below.
3-6 Status line 6 Call reference OXXXX call reference originating (Basic Rate OXX) DXXXX call reference destination (Basic Rate DXX) 7 Layer 3 decode SHORT display message type only MED display message type and information elements LONG display message type, information elements and full decode of information elements -- alarms displayed; layers 2 and 3 suppressed L2 layer 2 displayed in full; layer 3 suppressed E2 only Exception Conditions are shown on layer 2; layer 3 suppressed.
The PAP screen 3-7 Layer 1 status line Layer 1 status indicators are decoded from the value at the end of the displayed line, which is the sum of the individual hexadecimal values shown in the tables below. For example, simultaneous Primary Rate SYNC (08) and SES (02) errors are displayed as: Layer 1 Status Change 0A The left half of the layer 1 status line displays network side indicators, the right half displays user side indicators. There are different indicators for Primary Rate and Basic Rate.
