iMcV-T1/E1/J1-LineTerm TP/Fiber-SM1550/LONG-ST, 80km
The iMcV-T1/E1/J1-LineTerm is an SNMP manageable module that converts copper-based circuits (T1/E1/J1) to a single-mode or multi-mode fiber signal, extending the distance of data transmissions over networks up to 80 km. The iMcV-T1/E1/J1-LineTerm converter is perfect for service providers and enterprise campus networks utilizing T1/E1/J1 copper lines.
Line Termination Functionality
This module performs the standard "Line Termination" (GR-820-CORE) function of TDM-based line signals. This function transmits an Alarm Indication Signal (AIS) on the line whenever a received signal is lost. Line faults can easily be isolated to one line section and do not propagate over multiple-line sections as they do with normal line repeaters.
Hot-Swappable
Hot-swappable, iMcV-T1/E1/J1-LineTerm modules significantly reduce operation costs by allowing other modules within the same conversion chassis to remain up and running during network upgrades and maintenance. iMcV-T1/E1/J1-LineTerm modules install in any iMediaChassis or MediaChassis series.
Convenient DIP Switch Configuration
This converter series features a protocol-selectable operation to easily choose between T1/J1 and E1 rates via DIP switches located on the board. In addition, a DTE/DCE switch is conveniently located on the front of the unit to simplify cable connections.
Powerful Testing and Troubleshooting Features
To aid in network testing and troubleshooting, the T1/E1/J1-LineTerm features three different loopback test modes: copper loopback, fiber loopback and internal fiber loopback, to allow easy isolation of cable faults. The module also features a Transmit Data Source diagnostic tool which allows operators to choose from three specific patterns of data to identify transmission problems: transmit unframed all ones, transmit a pattern of alternating ones and zeros, and transmit a Pseudorandom Bit Sequence. In addition, the modules have built-in PRBS signal receivers, to simplify testing. All test modes are configurable remotely via iView² SNMP software or locally through DIP switches on the units.
Easy Remote Management and Configuration
The iMcV-T1/E1/J1-LineTerm is easy to install, configure and manage with iView² SNMP application software, or with any other SNMP application such as HP OpenView™. iView² runs: standalone on Windows NT/XP/2000; as a standalone Java Application for other operating systems; as a snap-in module for HP OpenView; as a Web Server running under IIS or as a Java Web Servlet. The advantage of remote management allows the network manager to monitor, configure and troubleshoot units located at the customer site without having to access the remote network. Furthermore, because the remote management technology is not in-band, the T1/E1/J1 converters transmit data at full bit rate while remaining transparent to data channels.
iMcV-T1/E1/J1-LineTerm modules are deployed in pairs (one at each end of a fiber line). The data transmitted on the fiber ports can only be received and interpreted by another iMcV-T1/E1/J1-LineTerm unit.
