The TELCO connection provides a convenient means of connecting to an
MDF-ready hub, switch or patch panel.
The “twister” Media Converter 7000 offers three models with TELCO
connectors. The LE7312A-PS-R2 is a 12-slot 2U chassis with dual 50-pin
TELCO connectors. This chassis is available with dual load-sharing power
supplies to ensure essential non-stop networking for high priority traffic
and business-critical applications. The LE7312A-R2 is a 12-slot 2U chassis
with a single power supply and dual 50-pin TELCO connectors. These
rack-mountable models fit standard 19” equipment racks and the 2U
chassis height provides housing for the maximum number of intelligent
“twister” modules. The LE7306A “twister” media converter, a
6-slot 2U chassis with a single power supply and a single 50-pin TELCO
connector, is designed for environments where the flexibility and function-
ality of a “twister” chassis is required but where a smaller number of slots
are needed. This unit is available with an optional wall-mountable bracket
for convenient attachment to a wall or other vertical surface.
The “twister” Media Converter 7000 provides the following key features:
•
A Link Loss Carry Forward (LLCF) enable/disable switch is
installed on the modules
*
as an aid to troubleshooting a
remote connection. Refer to the section of this guide titled
Link Loss Carry Forward for more information.
•
An MDI-
II
/MDI-X switch is installed on all TP ports.
**
•
Fused power on each module protects the rest of the modules
in the chassis from a short circuit. The power (PWR) LED
on an affected module does not illuminate if the fuse is blown.
•
Auto polarity support on all twisted-pair ports.
•
“redundant twister” modules can be configured to operate
in Dynamic Recovery Mode (DRM) to ensure session integrity
and increased uptime, or in Network Select Mode (NSM) to
redirect traffic and add security through link isolation.
*
Link Loss Carry Forward (LLCF) functionality is not provided on the LE7313C-R2 (BNC) or the
LE73XXC (TELCO) modules.
** This is not applicable to the LE7302C (TELCO) module.
