1 Introduction to the AVM ISDN-Controller T1/T1-B 1 Introduction to the AVM ISDNController T1/T1-B 1.1 The ISDN Network ISDN, the Integrated Services Digital Network, has been available in Germany since 1989, and is considered the universal telecommunications network of the future. Among ISDN’s characteristics are: - High speed The B channels, which are used to transmit user data, have a throughput of 64 Kbit/s.
1 Introduction to the AVM ISDN-Controller T1/T1-B 1.1.1 ISDN Line Types There are two standardized types of access to ISDN: - ISDN BRI (S 0 interface) with 2 B channels (64 Kbit/s each) and one D channel (16 Kbit/s) - ISDN PRI (S 2M interface) with 30 B channels (64 Kbit/s each) and one D channel (64 Kbit/s) Control functions for communication between the user and the network are handled over the D channel using the same protocols for the S0 and S2M interfaces.
1 Introduction to the AVM ISDN-Controller T1/T1-B The ISDN network ends at the subscriber’s premises in the network terminator (NT). This device provides the subscriber with the S2M interface. The abbreviation S2M refers to the total throughput at this interface, which is about 2 Mbit/s. The network operator may carry the signal over certain four-conductor paired copper cables (120W impedance), over coaxial cable (75W impedance), or over fiber optic lines.
1 Introduction to the AVM ISDN-Controller T1/T1-B Controller T1-B has a second processor board, for a total of 7 CPUs and 17 MB of RAM. Four CPUs are available for additional internal tasks such as V.42bis data compression on 30 simultaneous channels. The AVM ISDN-Controller T1 has one processor board with 3 CPUs and 9 MB of memory. The T1/T1-B is linked to the PC by a high-speed serial link to a PC bus interface card.
1 Introduction to the AVM ISDN-Controller T1/T1-B protocols V.110, V.120 and ISO 3309 are also supported. The ISO 3309 protocol is used primarily in the field of GSM cellular communications, as with Mobile ISDN. The AVM ISDN-Controller T1/T1-B conforms to the ITU-T I.431 recommendation and supports all 30 B channels and the D channel of the S2M interface at 64 Kbit/s. On the ISDN D channel, the T1-B supports both the European DSS1 protocol and the national protocol 1TR6.

2 Hardware Installation 2 Hardware Installation In order to maintain the full capabilities of the AVM ISDN-Controller T1/T1-B, please observe the following precautions: - The AVM ISDN-Controller T1/T1-B must not be placed in humid areas. - The ambient temperature should be between 15° and 35° C. The vents in the housing must not be obstructed. - The AVM ISDN-Controller T1/T1-B should be placed on a firm, stable surface or mounted in a 19-inch equipment rack.
2 Hardware Installation 2.1 Installing the PC Interface Card The AVM ISDN-Controller T1/T1-B is connected to the personal computer through a PC interface card. The PC interface card is a 2/3-length plug-in adapter for the ISA or EISA bus slot. For EISA bus architecture support, the configuration file !AVM0004.CFG is included on the DOS driver disk. Please consult your computer’s manual for further information on installing hardware components.
2 Hardware Installation 2.1.1 Installing Several PC Interface Cards In order to operate several AVM ISDN-Controller T1/T1-Bs in one computer, you must first assign a unique number to each PC interface card. This number is required so that each card can be addressed and initialized unambiguously. The number for the second and each succeeding ISDN-Controller must be assigned by setting the DIP switches found on the PC interface card (see illustration below.
2 Hardware Installation 2.2 Connecting the Cable from the PC Interface Card to the AVM ISDNController T1/T1-B After you have installed the PC interface card, it must be connected to the AVM ISDN-Controller T1/T1-B. To prevent interference in the high-frequency link, no extensions should be added to the cable supplied. 1. Connect the 15-pin sub-D connector of the cable supplied to the upper socket on the back plate of the PC interface card (see Fig. 1).
2 Hardware Installation 2. Connecting the ISDN-Controller T1 to the NTPMKU or NTPMGF (NTs with T-shaped mounting plate) Examine your NT and determine which type it is. In case of doubt, contact your ISDN operator’s technical service. When errors and malfunctions occur at the NT, the S2M interface may no longer synchronize with the local switch. In this case the switch temporarily disables the PRI. This is indicated by a red LED on the NT. Newer local switches re-enable the interface again automatically.
2 Hardware Installation 3. Remove the back covers of the inserts. 4. Screw the cable onto connector strip X2 on the terminal board. See Table 1 in Appendix C, Tables, for the pin assignments to connect the AVM ISDN-Controller T1/T1-B’s cable to the terminal strip. 5. Connect the cable leads to the correct terminals on the terminal strip. 6. Replace the cover over the terminals and lock it. 2.3.2 Connection to the NTPMKU or NTPMGF (NTs with T-shaped Mounting Element) 1.
3 Driver Software Installation – MS-DOS 3 Driver Software Installation Driver software for the AVM ISDN-Controller T1/T1-B is available for the operating systems Windows NT, Novell NetWare and MS-DOS. This chapter contains a section for each of these platforms describing the installation of the driver software, configuration of the ISDN-Controller, loading and unloading of the driver software, installation of additional controllers and removal of the ISDN-Controller from the system.
3 Driver Software Installation – MS-DOS Before you begin the installation, make sure the PC interface card(s) have been correctly installed in the computer. Make sure too that the I/O address 150 is not used by any other adapters in the PC. This is the default value used by the first PC interface card installed. If you want to operate several AVM ISDN-Controller T1s/ T1-Bs in one computer, you must first assign each PC interface card a unique card number.
3 Driver Software Installation – MS-DOS Now the installation routine copies all files to the selected drive and directory. If there is not enough free space on the drive, you will see an error message to this effect. Otherwise, the installation of the driver software is now complete. You may now start the AVM ISDN-Controller T1/T1-B. 3.1.2 Loading and Unloading the ISDN-Controller Initializing the AVM ISDN-Controllers T1/T1-B for operation takes place in two steps: 1.
