Introduction
The Verilink T Lite CSU provides an economical solution for
providing the T1 interface between customer premises equipment
and T1 facilities (telco or private). Each unit is compatible with
all T1 carrier transmission equipment and is designed to comply
with all industry-standard specifications. Both the transmitted
and received 1.544 Mbps signals are conditioned.
The T Lite is an industry standard, frame transparent T1 channel
service unit. It detects and activates network initiated loopbacks,
monitors bipolar violations, and maintains pulse density of the
transmitted signal. The unit works with any T1 line format and is
transparent to framed (D4 or ESF) or unframed T1 signals. The
T Lite is transparent to line coding and can operate in either AMI
or B8ZS coding. The T Lite can transcode B8ZS signals from
the network into AMI signals for the equipment and AMI signals
from the equipment into network B8ZS signals.
The unit is designed to be wallmounted using hook-and-loop
fasteners or “T” openings on the base (like a telephone). The unit
can also be set on a desktop.
The unit provides ALBO circuitry on the network receive path.
The network ALBO supports a receive range from +1 to
−
30
decibels. The DTE supports DSX1 signal ranges up to 655 feet.
The unit also provides line build out (LBO) circuitry on both
network and DTE. The network transmit LBO is user selectable
in four increments (from 0 to
−
22.5 decibels). The DTE transmit
LBO is user selectable in five increments from 0 to 655 feet.
The T Lite operates from an external VAC power source.
Network and DTE connections are made through RJ- 48C
connectors. The units have primary and secondary surge
protection on both the network and DTE side (meeting the UL
1950 requirements).
