Page 17 Chapter 1 Understanding ISDN and the ISU 512 ISDN OVERVIEW The Integrated Services Digital Network (ISDN) is a public or private switched digital network. ISDN is an international standard for digital communications, allowing a full range of enhanced services supporting voice, data, and image applications through standard interfaces over a single pair of telephone wires. Page 18 Chapter 1: Understanding ISDN and the ISU 512 The ISU 512 transmits data over an RS-530 or V.35 interface, selectable from the front panel. The ISU 512 performs at synchronous data transfer rates of 56 kbps to 512 kbps. At rates over 64 kbps, the BONDING Mode 1 inverse multiplexing protocol synchronizes data over up to eight 64 kbps B channels. By supporting BONDING, the ISU 512 interoperates with other BONDING-compatible inverse multiplexers and ISDN terminal adapters. Manually from up to ten stored numbers. Dialing while DTR is enabled. Page 20 Chapter 1: Understanding ISDN and the ISU 512 ISU 512 INTEROPERABILITY Telephone networks are evolving from analog technologies to digital technologies such as ISDN. This transition is time-consuming and costly for telephone companies and upgrading all locations and facilities is a lengthy process.http://www.lombardpruszkow.pl/local/userfiles/didger-3-manual.xml The ISU 512 bridges this transition by supporting communications with existing and future network services and equipment. Page 21 Chapter 1: Understanding ISDN and the ISU 512 RECOMMENDED OPERATING PROTOCOLS The ISU 512 supports BONDING Mode 1. For applications such as videoconferencing, in which the unit needs to interoperate with two SW56 lines or one dual-port ISDN device, the 2 x clear channel protocol (dual-port mode) is used. The ISU 512 automatically uses the 2 x clear channel protocol whenever it does not find a BONDING partner. The first call (incoming or outgoing) connects to the V.35 port in 2 x clear channel protocol. Page 22 Chapter 1: Understanding ISDN and the ISU 512 6 ISU 512 User Manual 61202. Page 23 Chapter 2 Ordering ISDN ISDN is a complex service with many network options. Obtaining service from the local telephone company and long distance providers can be complicated. The following instructions only apply to North American switches. In North America, the development of ISDN Ordering Codes (IOCs) simplifies the process of ordering ISDN service. Page 24 Chapter 2: Ordering ISDN For more information regarding ordering ISDN, see the ADTRAN document Ordering ISDN Service User Guide part number 60000.015-8, or contact the telephone company for alternative line configurations. The Ordering ISDN Service User Guide is available on the ADTRAN home page at (go to the Service and Support page and then to the ISDN Information Desk) or by calling ADTRAN at (205) 963-8000. 8 ISU 512 User Manual 61202. Page 25 Chapter 3 Installation INSTALLATION After unpacking the unit, immediately inspect it for possible shipping damage. If damage is discovered, file a claim immediately with the shipping carrier, then contact ADTRAN Customer Service; see the inside back cover of this manual for phone numbers. NETWORK CONNECTION The ISU 512 (U interface) supports either Dial or Leased operation. The ISU 512 (ST interface) supports only Dial operation.https://formations.fondationmironroyer.com/en/node/12877 The maximum cable lengths recommended are 50 feet for the RS-530 interface, or 150 feet for the V.35 interface. The pin assignments for the DTE interfaces are shown in the appendix Pinouts. The RS-530 interface and the V.35 interface support data rates up to 512 kbps. See the appendix Pinouts for the Chain In port pinout. The VT 100 terminal or null modem can be connected to the Chain In port using the RJ-45 to DB-25 adapter (part number 3196.ADPT003) and the RJ-45 to RJ-45 cable provided with the unit. The port contains transmit and receive data (EIA-232 compatible). Page 29 Chapter 3: Installation Software Update There are two methods available for updating ISU 512 software. The local method involves using the Chain In port and is described in this section. The remote method involves transmitting smart dial strings over a dial-up connection and is described in the section Remote Access of the chapter Configuration. The ISU 512 contains Flash memory allowing the software to be updated using the Chain In port. Page 30 Chapter 3: Installation VT 100 MENU INTERFACE The VT 100 menu interface can be used by connecting a VT 100 compatible terminal to the Chain In port on the back of the ISU 512. The VT 100 terminal (or PC running terminal emulation software) is connected to the Chain In port using the RJ-45 to DB-25 adapter (part number 3196.ADPT003) and the RJ-45 to RJ-45 cable provided with the unit. See the appendix Pinouts for the Chain In port pinout information. Page 31 Chapter 3: Installation Figure 3-2 VT 100 Configuration Menu Figure 3-3 VT 100 Configuration Menu 2 61202.

Page 34 Chapter 3: Installation 18 ISU 512 User Manual 61202. Page 35 Chapter 4 Operation INITIAL SELF TEST The ISU 512 performs an initial self test upon initial installation.http://www.dolciariavarone.com/images/colt-45-automatic-manual.pdf Once the self test is successfully completed, the current status mode is displayed. If the ISU 512 is not connected to the network, the Status menu displays DOWN next to the network connection number. If the unit is connected to the network and functioning properly, READY is displayed next to the network connection number; see Figure 4-1. Page 36 Chapter 4: Operation MENU STRUCTURE The ISU 512 uses a multilevel menu approach to access its many features. All menu operations are displayed in the LCD window or are available from the VT 100 terminal interface. The opening menu is the access point to all other operations. There are four Main menu branches: Status, Test, Configuration, and Dial. Each Main menu item has several functions and submenus to identify and access specific parameters. Page 37 Chapter 4: Operation Configuration (CONFIG) Menu Configuration selects network and DTE operating parameters. Dial Menu Dial provides manual dialing functions. Key in a number to dial or select one of the ten stored numbers. Basic Menu Traversal Four function keys on the left side of the ISU 512 keypad allow the various menu branches to be entered, exited, and scrolled through. The four function keys are defined below: Enter Up Arrow Down Arrow Cancel Selects flashing menu item. Scrolls up the menu tree. Page 38 Chapter 4: Operation 3. 4. Choose an item on the submenu such asNetwork Options (Netw.To select Dial Line options, press 1, then press Enter. This prevents unintentional reconfiguration of the ISU 512 during an active call. Page 39 Chapter 4: Operation LCD Window Displays menu items and messages in 2 lines by 16 characters. Enter Selects active menu items. To select a menu item, press the number of the item to activate. When the menu item is flashing, press Enter to select it. A submenu item is invoked or a configuration parameter is set. Numeric Keypad The numeric keypad contains the numbers 0 through 9, which are used to activate menu items and enter parameters. Cancel Stops the current activity and returns to the previous menu. Page 40 Chapter 4: Operation 24 ISU 512 User Manual 61202. Page 41 Chapter 5 Configuration USING ISDN BASIC RATE SWITCHED SERVICE This section explains how to configure the ISU 512 when using ISDN Basic Rate switched service. To dial calls over ISDN, the ISU 512 must be configured for Dial Line. Switch Type Find out what kind of ISDN switch the local CO is using by asking the telephone administrator or the telephone company representative. The Speech option is used with an ISDN line configured for voice service. In some areas voice service costs less than data service. A Speech call type does not guarantee an end-to-end digital connection with some local and long distance carriers. Audio Audio directs the call control software to request a 3. Page 45 Chapter 5: Configuration Terminal Identification Terminal identification is assigned by the local telephone company. Page 46 Chapter 5: Configuration Setting the LDN The local directory number (LDN) is used when placing or receiving BONDING calls. The LDN is the local phone number assigned to the line. This option allows the entry of up to eight LDNs. Use the Up and Down arrows to select the LDN to enter. This is the factory default setting. 10 sec or EON The ISU 512 assumes the dial string is fully entered if more than 10 seconds elapse since input of the last digit, or the unit receives the EON command. Page 49 Chapter 5: Configuration Auto Answer The ISU 512 can be configured to automatically answer or not answer. The ringing call can be dumped using the Hang Up Line command. Page 51 Chapter 5: Configuration 3. 4. 5. Place a call to the ISU 512 with the stored number to see if it answers. If the ISU 512 does not answer the call, look at the Call ID message in the Status buffer. More than likely, the Call ID number is a ten-digit number Store the number in SN0 as it is displayed in the Call ID message and test Call Screening again. Page 52 Chapter 5: Configuration Remote Supervision The ISU 512 has the ability to be remotely accessed and configured from another ISU 512. The ISU 512 can be protected from illegal access by using the password protection built into the remote protocol. Page 53 Chapter 5: Configuration Maintenance Setup There are three Maintenance Setup options: Auto Traps, ADLP Address, and Port Mode. The ISU 512 monitors and reports alarms for network failures or degrading performance conditions. The ISU 512 can be configured to generate protocol traps autonomously by selecting Enable. To disable protocol traps, select Disable. Page 54 Chapter 5: Configuration Call NumID When Call NumID is enabled, the ISU 512 will send the caller ID INFO setup message to the ISDN switch. When Call NumID is disabled, the caller ID INFO setup message will not be sent to the ISDN switch. 38 ISU 512 User Manual 61202. Page 55 Chapter 5: Configuration CONFIGURING THE ISU 512 FOR LEASED DIGITAL SERVICE This section explains how to configure the ISU 512 when using a 2B1Q Leased Digital service or a service that provides a permanent connection between end points. This mode is only supported by the ISU 512 (U interface). Page 57 Chapter 5: Configuration Test Remote When the Test Remote option is enabled the unit performs an automatic 2047 BERT of the line(s) immediately following BONDING connection. When disabled (default), no test is performed after initialization. Maintenance Setup There are three Maintenance Setup options: Auto Traps, ADLP Address, and Port Mode. Page 58 Chapter 5: Configuration SETTING DTE OPTIONS The DTE Options menu is used to select the configuration parameters that control the operation of the DTE interface ports of the ISU 512, such as the maximum bit rate and the connector type. Changes to the DTE options affect both ports (RS-530 and V.35) during dual-port mode and single-port modes of operation. Maximum Bit Rate The DTE bit rate can be set for 64K MODE 1 or 56K MODE 1. Page 59 Chapter 5: Configuration Connector Type Specify the interface by selecting the desired connector type. Setting this option to Enabled allows the use of the RS-530 to V.35 cable. This cable converts the RS530 connector to a V.35 interface. Page 60 Chapter 5: Configuration CTS Options Selecting Forced CTS causes the CTS signal on the DTE connector to be continually asserted. Follow RTS causes the CTS signal to follow the state of the RTS lead. Follow CD causes the CTS signal to follow the state of the CD lead. Off V.25 ANSR drives CTS off while answering a call with V.25 bis dialing enabled. This setting is used for Panasonic video conferencing equipment with V.25 bis dialing enabled. The unit attempts to establish a call using SN0-SN4 until the call is established or DTR goes inactive. Page 62 Chapter 5: Configuration BONDING SETUP The ISU 512 communicates with many different types of telecommunication equipment including other ISU 512s, ISDN terminal adapters, Switched 56 DSUs, and BONDING mode 1-compatible inverse multiplexers. The ISU 512 supports the BONDING mode 1 (Bandwidth on Demand Interoperability Group) adaptation protocol. See Recommended Operating Protocols in this chapter for more information on recommended modes of operation. Page 63 Chapter 5: Configuration TXFA This option specifies the length of time both endpoints attempt to detect the BONDING frame pattern when a call is connected before deciding the BONDING call has failed. This timer value should be left at the factory default setting of 10 seconds. However, when interoperating with other manufacturers’ BONDING equipment, it may be necessary to lengthen this timer so that it matches TXADD01. Select from values of 1, 2, 5, 10 (default), 20, 50, 100, and 200 seconds. Page 64 Chapter 5: Configuration TCID This option specifies the length of time both endpoints attempt to negotiate an agreeable value for bearer channels and channel capacities before deciding the BONDING call has failed. This timer default setting is 5 seconds. Values of 1, 2, 5 (default), 10, 20, 50, 100, and 200 seconds can be selected. Call Stagger This option specifies the amount of delay placed between calls. The default setting is 0 ms (no delay). During incoming and outgoing calls, the ISU 512 attempts BONDING mode 1 protocol first. Page 66 Chapter 5: Configuration Videoconferencing equipment should be set for delayed second call dialing when using the RS-366 Y cable for dialing 2-clear channel calls. QUICK SETUP CONFIGURATION To configure the DTE Options quickly and easily, the Quick Setup menu is available to automatically set up the eight most common DTE configurations. Dial Number Allows a number to be entered and dialed from the key pad. Press the Up and Down arrow keys to scroll through the 10 stored numbers (SN0 - SN9). To store a number, scroll in the desired stored number location, enter the number, and press Enter to save. If a mistake is made, press Cancel to clear the line and allow another attempt. The ISU 512 supports V.25 bis in-band dialing in accordance with Fascicle VIII.I - V.25 bis (Malaga-Torremolinos 1984, Melbourne 1988). This allows performance of a bit error rate test (BERT) between the ISU 512 and end user equipment to verify proper cable connection, etc. This allows 2047 BERT patterns to be run on multiple ISDN connections (through BONDING). The originating ISU 512 generates the 2047 patterns and checks the incoming pattern for errors. The test is run for a period of time defined in S-register 26. The larger the value in S26 the longer the test runs before entering data mode. An incrementing count of NEBEs indicates a problem on the local loop from the switch to the NT-1. An incrementing count of FEBEs indicates a problem on the local loop from the NT-1 to the switch. Page 76 Chapter 6: Testing 60 ISU 512 User Manual 61202. Page 77 Chapter 7 Troubleshooting IF SELF TEST FAILS When the ISU 512 powers up, it performs an internal self test. This takes approximately 10 seconds. At the end of the test, the front panel displays Self Test Passed. If Self Test Passed is not displayed, perform the following procedure to verify if the problem can be solved locally: 1. Ensure the ISU 512 is receiving power and is switched On. 2. Turn Off the ISU 512; while holding the 0 key, power up the ISU 512. Page 78 Chapter 7: Troubleshooting directory number(s) provided with the ISDN line. Calling a good ISDN line with nothing connected usually results in a ring or fast busy tone. If the call is completed or a not-in-service intercept is received, then there is probably something wrong with the translation of the ISDN line. Contact the phone service provider for help. 3. If the ISU 512 continues to read DOWN, there is a physical problem with the ISDN line (probably Layer 1 setup). Page 79 Chapter 7: Troubleshooting F. Ensure nothing else is bridged across the ISDN line pair. G. With a minimum of extra wiring, try connecting to the line pair at the point where service provider's wiring ends. H. With the ISU 512 connected to the ISDN line and powered up, contact and inform the service provider's repair group that your ISDN basic rate line has a Physical Layer 1 problem. Request the ISDN line be checked. Page 80 Chapter 7: Troubleshooting 3. Connect another piece of functioning ISDN equipment to the ISDN line. 4. With the ISU 512 connected to the ISDN line and powered up, talk to your service provider's repair group and tell them you have an ISDN basic rate line that appears physically OK but has no terminal endpoint identifier (TEI). Ask them to check the line translation and ensure that ISDN the line supports Dynamic TEI allocation.
