GDC DataComm 554 T1 FT1 CSU DSU |
The General DataComm DC554 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 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 E IA-530 interface
for interconnecting FAN 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 alI standards for
T1 and FT1 access_ The DataComm 554 supports both the ANSI and 54016 versions of
Extended Super Frame (FSF), 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 control led
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 excusive 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 to 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 and 3:24, to stress test the T1 link, as well as CCITT 511 and
2041 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.
