Resumen del manual
Two directory numbers are required for 2B operation. In this case, use J2. 61200051L1-1D ISU 2x64 Dual Port ISDN Service Unit User Manual Chapter 2.ISDN Service J2 (previously Generic Data J) • 2B service • 1B alternating voice/data, 1B data only • Two directory numbers M5 (previously Generic Data M-1DN) • 2B Service • 1B alternating voice/data, 1B data only • One directory number M5 is not available for services provided by Northern Telecom or AT&T switches. ISU 2x64 Dual Port ISDN Service Unit User Manual 61200051L1-1D Chapter 3 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 Technical Support. Each ISU 2x64 is provided with an eight-foot power cord terminated by a three-prong plug which connects to a grounded power receptacle. ADTRAN ISU 2x64 part numbers 1200051L1, 1200051L2, and 1200051L5 require a grounded 115 VAC, 60 Hz receptacle for power. ADTRAN ISU 2x64 part numbers 1200051L3, 1200051L4 and 1200051L6 require a 230 VAC, 50 Hz receptacle for power. NETWORK CONNECTION An eight-pin RJ-45 modular jack on the rear panel of the ISU 2x64 allows connection to ISDN Basic Rate service provided by the telephone company or to a leased type of service. This leased service can be dedicated 2B1Q data service or a nailed-up circuit that provides a dedicated connection between end points such as a limited distance modem or LAD circuit. If using ISU 2x64, part number 1200051L1 or 1200051L3, connect the telephone company provided ISDN Basic Rate U-Interface to the RJ-45 connector marked ISDN IFC. An external NT1 is not needed in this configuration. 61200051L1-1D ISU 2x64 Dual Port ISDN Service Unit User Manual Chapter 3.Installation If using ISU 2x64, part number 1200051L2, 1200051L4, 1200051L5, or 1200051L6, connect an ISDN Basic Rate S/T interface to the RJ45 connector marked ISDN IFC. The S/T interface can be provided from an S/T line card of an ISDN switch or PBX, or from an NT1 network termination unit. If using a leased service, connect the network interface to the RJ45 connector marked ISDN IFC. See Connector Pinouts on page 119 for network connection pin assignments. DTE DATA CONNECTION Data terminal equipment (DTE) is connected to the ISU 2x64 by using the RS-530/EIA-232 interfaces or by using the external RS530- to-V.35 adapters (part number 1200072L1). A maximum cable length of 50 feet is recommended for the RS-530/EIA-232 interfaces. If using the RS-530-to-V.35 adapter and connected to a full specification V.35 interface, the maximum recommended cable length is 15 feet. The pin assignments for the DTE interfaces are shown in Connector Pinouts on page 119. Be sure to configure the menu option for the connector type used in your application. See DTE Options for Asynchronous and Synchronous Operation on page 50. The RS-530/EIA-232 interface and the RS-530-to-V.35 interface supports data rates up to 128 kbps. The DTE rate is configured from the front panel of the ISU 2x64 or by using AT commands. See Configuration to configure the ISU 2x64 with the appropriate data rates for your application. To prevent possible radio frequency interference emissions, a shielded V.35 cable is required. ISU 2x64 Dual Port ISDN Service Unit User Manual 61200051L1-1D Chapter 3. Installation MAINTENANCE INTERFACE The Maintenance interface is available at 9600 bps, 8 data bits, no parity, no flow control, asynchronous format through the Maintenance port. See Connector Pinouts on page 119 for the pinout of the Maintenance port. A VT 100 terminal or null modem can be connected to the Maintenance port using an EIA-232 cable. This interface can be used to set internal S-registers, dial ISDN connections, and disconnect calls. This port also allows ADTRAN Technical Support personnel to retrieve vital information from the unit if a problem is encountered during initial configuration of the ISU 2x64. Most problems can be solved without resorting to this port for assistance. The ISU 2x64 Maintenance Help Screen can be activated by typing !? at either the DTE#1 or DTE#2 prompt. The screen is shown in Figure 3-1.

Pin assignments for the RS-366 connector are listed in the appendix, Connector Pinouts. ISU 2x64 Dual Port ISDN Service Unit User Manual 61200051L1-1D Chapter 4 Operation MENU NAVIGATION Moving through the various menu selections on the ISU 2x64 is a simple task. Four function keys on the left-hand side of the key pad allow the user to enter, exit, and scroll through the various menu branches. The four function keys are defined below. To aid the reader...
