T1/E1/J1 Modules
T1/E1/J1 modules for the High-Density Media Converter System II
enable you to extend 1.544-Mbps T1/J1 or 2.048-Mbps E1 copper-
based circuits over duplex fiber optic cable. They’re ideal for use with
PBX systems or legacy telco circuits.
These modules are selectable to support 1.544-Mbps T1
(ANSI T1.403), 2.048-Mbps E1 (G.703), or 1.544-Mbps J1.
They include full diagnostics, including three modes of operation
for loopback testing (Fiber Analog Loopback, Fiber Digital Loopback,
and Twisted-Pair Digital Loopback), a line integrity test feature,
and a Transmit Data Source diagnostic feature. Built-in jitter removal
ensures maximum throughput. An MDI/MDI-X switch configures the
RJ-48 port for crossover or straight-through cable connection
automatically. This eliminates the worry of whether to use straight-
or cross-pinned cabling.

10-/100-Mbps Ethernet VDSL2 Extender Module
Item Code
High-Density Media Converter System II Ethernet VDSL2 Extender Module
(1) Twisted-Pair RJ-45 to (1) RJ-11 VDSL2
LMC5601C-VDSL2
The 10-/100-Mbps Ethernet VDSL2 Extender Module provides an
easy, affordable way to extend a 10/100 Ethernet network over exist-
ing CAT3 voice-grade wiring within buildings or sites. It uses second-
generation VDSL2 technology (Band Plan 997/998) and offers user-
selectable symmetrical and asymmetrical data transmission. The
extender provides maximum VDSL bandwidth and adjusts automati-
cally to obtain best bandwidth performance.
