aurora Plus User Guide The ISDN The Integrated Services Digital Network (ISDN) is a telecommunications network designed to transmit and process all types of voice and data traffic using digital transmission and switching. The ultimate goal of ISDN is to provide a common set of interface standards that will allow worldwide access for users. There are two types of ISDN service: the Basic Rate Interface (BRI) and the Primary Rate Interface (PRI). BRI uses a standard 2-wire telephone line to provide two B (or bearer) channels supporting transmissions at 64 kbps and one D-channel at 16 kbps. Because of this, BRI is also commonly referred to as 2B+D. The B-channels can carry voice, circuit switched data, or packet switched data at rates up to 64 kbps; the D-channel carries signaling information or packet switched data at rates up to 16 kbps. BRI is typically used for a connection to a residence or small office. PRI provides 23 B-channels and one D-channel, all supporting speeds up to 64 kbps. In PRI, the B-channels are again used for voice or data, and the D-channel is used for signaling or packet switched data. PRI is typically used for connections to an ISDN PABX in a large corporate office. A typical configuration for an ISDN BRI connection is shown in Figure 1. The various components in the network are identified as network terminations and terminal equipment. The interface points are identified as R, S, T, and U. These components are explained in the tables following the illustration. 1-2 429864

aurora Plus User Guide Definitions and Explanations To better understand the operation of the aurora Plus, it helps to understand how different parts of the Basic Rate ISDN service are identified in operation. The first part of this section clarifies the difference between the central office switch that is providing the ISDN service and the D-channel protocol that the switch is using to control calls. The next part discusses some important differences among frequently confused ISDN terms: Terminal Endpoint Identifier (TEI), Service Profile Identifier (SPID), Directory Number (DN), and B-Channel. Switch Type and Protocol ISDN users and technicians often confuse the type of central office switch that is providing an ISDN service with the D-channel protocol that the switch is using to control calls. This confusion arises because, when ISDN first appeared, each of the major switch vendors offered its own variation on the standard D-channel protocol. Later, to reduce confusion and to make ISDN services more widely available, the North American telecommunications industry adopted the National ISDN standard to replace the vendors custom protocols. Some of the behavior of the ISDN circuit and the aurora Plus depends specifically on switch type and applies whether the switch is using the National ISDN protocol or a custom protocol. A circuit s switch type is simply the make and model of the central office switch providing the ISDN service. In North America, the most frequently used brands of central office switches are the AT&T 5ESS and the Nortel DMS 100. 1-6 429864
Introduction The protocol used on an ISDN circuit is the specific set of messages and procedures used on the D-channel to control calls. Three major variations of the D-channel protocol are used in North America: the National ISDN protocol, the AT&T Custom protocol, and the Nortel Custom protocol. The AT&T and Nortel Custom protocols run on AT&T and Nortel switches, respectively; the National ISDN protocol can run on any type of switch. The AT&T Custom protocol uses two different connection modes: point-to-point (PP) and point-tomultipoint (PMP). Addresses and Identifiers in Basic Rate ISDN Because it must support the wide range of services and features that ISDN offers, the Basic Rate Interface is fairly complex. First of all, the interface is divided into three channels. The two B-channels carry only the user s voice or data calls. The D-channel carries the signaling messages that control calls on the B-channels; it can also carry low-speed packet switched (X.25) data communications. Some additional complexity arises because the ISDN Basic Rate Interface is designed to support more than one device at a time. The S-interface, described earlier, is a bus that can connect up to eight different devices (telephones, fax machines, computers, data terminals, etc.) to the Basic Rate Interface (although only two of them can be active at once). The central office switch needs to be able to distinguish between the different devices so it can direct calls to specific devices. The switch also needs to be able to restrict the services it is offering to the set of services that the user has actually ordered. Issue 2-04/00 1-7
aurora Plus User Guide Service Profiles and SPIDs The Service Profile of a BRI service is a record in a data base that the central office switch uses to determine how to serve a specific customer and how to handle specific commands and requests (such as feature keys) from a piece of Customer Premises Equipment. In most cases, when BRI services are provisioned, each terminal device on the service receives one or more Service Profile Identifiers (SPIDs) that identify the service profiles assigned to the service. (Circuits using the AT&T Custom protocol with point-to-point connection type do not use service profiles and, therefore, have no SPIDs.) The SPID usually includes the service s directory number and some additional digits of information. The ISDN user receives a written copy of the SPIDs for his BRI service from the service provider. The TE device must be programmed with SPIDs in order to initialize Layer 3, and subsequently place ISDN calls. Depending upon the software revision active in the switch and in the TE, the TE either requests SPIDs from the switch or submits pre-programmed SPIDs to the switch. When the aurora Plus initializes, it sends a message to the switch requesting the SPIDs for the line. If the switch does not respond, the aurora Plus then tries to guess the SPIDs for the line based on the values resident in nonvolatile memory. The contents of SPID1 and SPID2 are assumed to be directory numbers, and are used with the National ISDN SPID Simplification rules to derive SPID numbers and submit them to the switch. Some ISDN switches (such as the 5ESS) can connect multiple B-channel calls with only one SPID. Others, such as some versions of the Nortel DMS 100, require a separate SPID for each active call. Note that this feature depends on switch type and not on protocol. 1-8 429864
Introduction TEI B-Channel The Terminal Endpoint Identifier (TEI) is a portion of the address that identifies a device on the D-channel for call control signaling. From the viewpoint of the signaling protocol, a Terminal Endpoint can be an actual, physical terminal, or it can be a logical entity associated with part of a basic rate service. Whenever a BRI service is initialized (i.e, turned up), the switch assigns one or more TEIs to the circuit. In North American ISDN, a TEI is uniquely associated with a service profile (i.e., one TEI is assigned per SPID). In some instances, a specific service requires that a specific fixed TEI be assigned. D-channel X.25 service on a Nortel switch is an example of this. When a terminal device such as the aurora Plus begins to turn up the interface, it requests a TEI assignment and then transmits its SPID over the data link associated with that TEI for verification. (For a second Service Profile, it repeats the process and receives another TEI.) For terminals or services that use a fixed TEI, the terminal simply tells the switch which TEI will be used for messages for that service. A BRI service can have one or more directory numbers. These are the ordinary telephone numbers used to dial that service from the outside. Customers and technicians often confuse the directory number with the SPID. The directory number is usually part of the SPID, but the SPID usually contains additional digits. A B-channel on a BRI service is one of two 64 kbps digital channels available for voice or data calls. In most cases, specific B-channels are not associated with specific directory numbers or SPIDs. This allows the central office to assign an incoming or outgoing call for an ISDN service dynamically to the first available B-channel. Issue 2-04/00 1-9

Your aurora Plus comes equipped with a cable already attached to this connector into which you plug your ISDN cable. The aurora Plus cable should remain attached to the unit at all times. Your selection on the keypad will determine whether the S or U interface is used for testing. Data Communications Port The Data Communications port is also located at the same end of the tester as the mouthpiece. This port is used for programming the flash memory in your tester and requires a special 8-pin DIN-to-DB-9 cable that is included with your aurora Plus. Instructions for programming the flash memory are given in Chapter 5. 2-2 429864
Battery Charger A Look at Your aurora Plus The 9-12 VDC battery charger connector is located above the S/U interface connector. NOTE Switches and Keys You must charge the battery before using the aurora Plus under battery power for the first time. The battery takes approximately two hours to receive a full charge. Please refer to the section Power later in this chapter for complete instructions on charging the battery. There are two switches on the sides of the aurora Plus and three switches on the bottom row of the keypad. (When the switches on the bottom row of the keypad are pressed [= on], the white border is not visible. When they are not pressed [= off], the border is visible.) These switches are described below. Switch Name ISDN ANALOG/POTS CHARGE/BAT LINE MON TERM Function Selects either the ISDN or optional analog test interface. Determines the source of power for the aurora Plus.

Testing with Your aurora Plus Testing with Your aurora Plus U-Interface Turn-up and Service Check 3 You can use the U-interface turn-up and service check described below to check newly installed circuits. This test shows that the circuit can be initialized and then determines which services are available on your ISDN connection for outgoing calls, letting you verify that you received the services you ordered. The test consists of four basic steps: Making the connection to the interface Selecting the protocol and connection mode Programming the required SPIDs Initiating the service check To set up the test, you will need to know how your ISDN connection is provisioned, including the type of central office switch, the ISDN protocol (AT&T, National ISDN, or Northern Telecom), and the connection type (point-topoint or point-to-multipoint) used on the circuit under test. Use the following steps to initialize and test the line: 1 Make sure that the S/U switch on the keypad is in the down (U) position. 2 Set the ISDN/Analog POTS switch to ISDN. 3 Connect the appropriately terminated U-interface cord from the aurora Plus to the ISDN U-interface connector of the circuit under test. 4 Set the Charge/Bat switch to Bat.

aurora Plus User Guide In North America, the switch uses a SPID to identify which software features a piece of terminal equipment has access to. Upon Layer 3 initialization, aurora Plus attempts to poll the switch for SPID numbers registered to that interface. If the switch does not respond (indicating that it is not AutoSPID capable) the aurora Plus then tries to guess the SPID(s) for the line using the values in the SPID1 and SPID 2 registers as the basis for the calculation. To configure the SPID(s) manually: NOTE SPIDS are used on a BRI service in point-tomultipoint mode. If you are using the AT&T protocol in point-to-point mode, a SPID is not required and will not be transmitted even if you enter one. In this case, you can skip to step 20. Steps 11 through 19 explain how to program the SPIDs manually if you know them. If you do not know the SPIDs, use this procedure to fill in the 10 digit DN(s) for the line in place of the SPIDs. When connected, aurora Plus will attempt to use AutoSPID. If this fails, aurora Plus will use the DNs you have entered to automatically derive and submit the SPIDs. If this guessing algorithm fails, you must enter the SPIDs manually. 11 Press 2 (SPID) to access the SPID menu. The SPID menu appears. 1 SPID1 2 SPID2 0 EXIT 3-4 429864

NOTE You need enter only the 10 digit directory number. If the switch is not AutoSPID capable, aurora Plus will add known prefixes and suffixes to this number until a correct response is received from the switch.

Testing with Your aurora Plus The U-interface can take over one minute to initialize, and during this time the screen will display the initializing message and indicate the status of layers 1, 2, and 3 with arrows. When the physical layer of the interface becomes active, the tester will briefly display a layer 1 status message and you will see L1 at the bottom of the screen. This indicates that the physical circuit is working correctly. When the data link layer of the interface becomes active (i.e., when the switch has assigned TEIs to the aurora Plus ), the tester will display a Layer 2 status message and you will see L2 at the bottom of the screen. aurora Plus then sends a message to the switch to request the SPIDs for the line. Initiating Auto SPID L1 L2 L3 If the switch fails to send the SPIDs aurora Plus starts to generate SPIDs to guess the SPIDs of the line. 1st attempt SPID1 guess L1 L2 L3 When the signaling protocol becomes active and the switch has accepted the first SPID, the tester will display SPID 1 OK (and possibly SPID 2 OK) and you see L3. This progression of messages layer through three stages of layer activation can provide important diagnostic information if the circuit fails to initialize. When the initialization is complete, the IDLE message appears. This sequence of messages is an important diagnostic aid in ensuring that the ISDN line initializes properly. Issue 2-04/00 3-7
aurora Plus User Guide Idle L1 L2 L3 NOTE While initializing the U-interface, the switch transmits a few control messages over the Embedded Operations Channel (EOC). The aurora Plus displays these messages as they are received. You can access this information under the Status display. If there is a problem: If you do not see L1 (layer 1 up) after about two minutes, one of the following conditions applies: The S/U selector button on the aurora Plus is in the wrong position. The cable from the aurora Plus is not connected to the ISDN circuit. There is no ISDN service on the circuit. If you have set up the tester correctly, but it still does not display L1 after approximately three minutes, the physical layer of the circuit has failed and must be repaired before any further initialization or testing is possible. If the tester displays L1 but shows L2 after approximately three minutes, the switch and the tester have failed to establish a data link; this indicates a probable hardware failure in the switch. If the message L2 TEI err appears, this provides a positive indication of a failure at layer 2. If the tester displays L2 but fails either to accept or reject the first SPID within a few minutes, it displays SPID1 timed out, check setup. This indicates a timeout for the SPID acceptance, which usually means failure in the switch. 3-8 429864

You can send packets just as you can when you initiate the call. Dual B-Channel Data Call Test The 2B Check verifies that the service under test can accept two simultaneous, outbound B-channel data calls; this provisioning option allows an ISDN user with the correct terminal equipment to make a 128 kbps bonded data call. This test is designed to run on data channels only; it will fail if one or both of your B-channels are configured only for voice. If you need to determine how your B-channels are configured, refer to the U-Interface Turn-up and Service Check procedure earlier in this chapter. If the BRI circuit that you are testing uses either the National ISDN or Nortel Custom protocol, you might need to enter two valid SPIDs at initialization time to perform the 2B Check correctly. If the BRI circuit uses the AT&T Custom protocol in point-to-multipoint mode, then at least one SPID is required. (With the point-topoint connection type for the AT&T Custom protocol, no SPIDS are required.) If you have not set up the connection, protocol, or SPIDs, or you have not yet initialized the circuit, start here: 1 To set up the test on the U-interface, follow steps 1 through 5 of the U-Interface Turn-up and Service Check earlier in this chapter.

Testing with Your aurora Plus Testing for Bit Errors Once you have verified the SPID(s) on the BRI circuit, you can perform a BERT (Bit Error Rate) self-call for any ISDN service (speech or data) to check the quality of your ISDN line. You set up a call either to the second B-channel on your aurora Plus or to a remote test device for a length of time of your choosing (30 seconds, 1 minute, 5 minutes, 15 minutes, continuously, or a user-defined duration). The data received during the test is checked for errors, and the number of errors and the corresponding error rate are displayed once the test is completed. See Setting Up a Loop in Chapter 5 if you want to loop incoming calls for BERT testing with another device. You can run a BERT test during any outgoing call. However, the test will use the parameters (BERT duration) that have been set up previously. If you have not set up the connection, protocol, or SPIDs, or have not initialized the interface, start here: 1 To set up the test on the U-interface, follow steps 1 through 5 of the U-Interface Turn-up and Service Check earlier in this chapter. 2 If the correct protocol and connection mode have not yet been set up, follow steps 6 through 10 of the U-Interface Turn-up and Service Check earlier in this chapter. 3 If the correct SPIDs have not yet been entered, and you want to enter them manually, follow steps 11 through 21 of the U-Interface Turn-up and Service Check earlier in this chapter. 4 If you have not yet initialized the interface, follow step 22 of the U-Interface Turn-up and Service Check earlier in this chapter.
