GDC DataComm 554
MOVING FROM 56 KBPS TO 1.536 MBPS

 OVERVIEW

The DataComm 554 is a high performance, single-channel CSU/DSU designed to support full and fractional T1 (FT1) applications that do not require added wide-area network management.  It is the ideal solution for applications that have outgrown 56 Kbps and require faster data transport.

The DataComm 554 supports a V.35 or optional EIA-530 interface for interconnecting LAN Bridge/Routers, T1 Multiplexers, Video
Teleconferencing gear, CAD/CAM, and Medical Imaging applications that demand the speed and performance offered by today's attractively priced FT1 services.

The DataComm 554 operates at all X x 56/64 Kbps rates from 56 Kbps to 1.536 Mbps (where N=1 to 24), adhering closely to all standards for T1 and FT1 access. The DataComm 554 supports both the ANSI and 54016 versions of Extended Super Frame
(ESF), as well as AMI and B8ZS (clear channel) line coding, to ensure compatibility with the latest digital services. In addition, it supports the AT&T 54019A specification for FT1 transmission a requirement for Frame Relay, today's increasingly popular LAN/WAN interconnect service.

EASY INSTALLATION 

From the start, the DataComm 554 has been designed to simplify installation and maintenance. Unit configuration is performed by setting clearly marked on-board option switches.   An array of front panel controlled tests and LEDs facilitates the installation process by verifying equipment operation as well as identifying signal status and warning the user of alarm conditions.  To make things even easier, the DataComm 554 automates both Line Build-Out (LBO) and framing format selection.

As far as performance is concerned, the DataComm 554 employs GDC's exclusive Extended Dynamic Range technology to ensure the most trouble-free operation possible over the widest range of T1 circuits.

POWERFUL DIAGNOSTICS


The DataComm 554 supports a full complement of diagnostic tests isolate and quickly resolve system faults. Network Administrators can command local and remote diagnostic loopbacks directly from the equipment's
front panel to pinpoint faulty circuit and/or equipment problems. The DataComm 554 even has a built-in test pattern generator/error detector to minimize the need for external test equipment!  For added flexibility, the network administrator can select from multiple patterns, including QRSS 3:24, to stress test the T1 link, as well as CCITT and 2047 test patterns for the data channel. Unlike most other T1 CSU/DSUs, the DataComm 554 has front panel test jacks to facilitate "break-in" testing and non-interfering monitoring of in-service activity.  In addition, the DataComm 554's network performance ESF registers provide the carrier with in-service statistics to help it monitor the overall performance of the network.

FLEXIBLE PACKAGING DESIGN

The DataComm 554 follows GDC's extremely flexible Data -Commonality packaging design. It is available in high density rackmount units up to 16 can be installed in a 19-inch or 23-inch shelf or in an attractive, compact standalone enclosure.
