ISU 2x64

DUAL PORT ISDN SERVICE UNIT
1200051L1 and 1200051L2

The ADTRAN ISU(TM) 2x64 (part# 1200051L1 or 1200051L2 ) is a standalone ISDN Service Unit that connects data terminal equipment to the ISDN network. The ISU 2x64 is a dual port ISDN Terminal Adapter with an integrated NT1. The unit provides a cost-effective solution for the transfer of data and images over a single ISDN line.

The ISU 2x64 (part# 1200051L1 or 1200051L2 ) can be viewed as a dual modem that supports two applications, simultaneously and independently, up to 64 kbps on each DTE interface. For high speed applications over 64 kbps, a single DTE interface can achieve rates up to 128 kbps. Target applications for the ISU 2x64 unit include video conferencing and audio broadcasting at 128 kbps, as well as dual modem replacement.

The ISU 2x64 responds to loopback commands from the telephone company Central Office for network testing. An S/T interface version of the ISU 2x64 is also available for applications that do not require an internal NT1.

The ISU 2x64 (part# 1200051L1 or 1200051L2 ) features dual RS-530/EIA-232 DTE interfaces and dual RS-366 dial interfaces. An RS-530A/EIA-232-to-V.35 adapter is available to support V.35 DTE interfaces.

A single DTE interface supports synchronous data transfer rates from 2400 bps to 128 kbps and asynchronous rates from 1200 bps to 115.2 kbps. When using dual DTE interfaces, synchronous data transfer rates from 2400 bps to 64 kbps and asynchronous rates from 1200 bps to 57.6 kbps are supported. For speeds over 64 kbps using a single DTE interface, the industry standard Multilink PPP or BONDING delay equalization protocols aggregates the two 64 kbps B channels for a maximum of 128 kbps.

Dialing from the ISU 2x64 (part# 1200051L1 or 1200051L2 ) is accomplished by using the front panel, stored numbers, DTR assertion, AT commands, or V.25 bis in-band dialing. Dual RS-366 parallel dial interfaces are also provided, which can be used for applications such as videoconferencing.

The front panel of the ISU 2x64 (part# 1200051L1 or 1200051L2 ) consists of a two-line by 16-character display, seven LEDs, and a 16-button keypad. This allows for configuring, dialing, testing, and monitoring of the unit without a data terminal or test equipment. AT commands may also be used for configuration and status monitoring.

In addition, the ISU 2x64 (part# 1200051L1 or 1200051L2 ) can be configured and maintained locally or remotely using a VT100 terminal interface. For remote configuration, the unit can be accessed over the ISDN or externally through the maintenance port on the back panel.
