| Applications
The Telinc TL5140 T-3 Dechannelizer can select and breakout
any four of twenty-eight T-1 channels on a channelized T-3
facility. It can monitor both the transmit and receive path
of the T-3 facility simultaneously and provide two transmit
pairs out each of the four T-1 ports. Both T-3 Monitor ports
on the unit are designed to access the T-3 transmit and receive
signals through a DSX3 patch panel. The TL5140 T-3 Dechannelizer
includes a 20 dB amplifier on each of the T-3 Monitor ports
which enables the unit to amplify and recover the attenuated
signals. A built-in cross-connect switch enables the selection
of any four of the 28 T-1 channels. No configuration is necessary
since the TL5140 automatically detects whether the T-3 facilities
are provisioned for M13 or C-Bit.
The
TL5140 Dechannelizer can be controlled from a local or remote
ASCII console. The user-friendly console enables selection
of the four T-1 channels by hitting the ENTER or BACKSPACE
key. Only five keys are used in the total operation of the
console.
The
rear panel consists of 6 BNC connectors for T-3 ports, 4 RJ48C
connectors for T-1 ports, an RJ11 connector for the console
port and an AC connector.
DSX3
Monitor Mode
The Telinc TL5140 T-3 Dechannelizer can select and breakout
any four of twenty-eight T-1 channels on a channelized T-3
facility. It can monitor both the transmit and receive path
of the T-3 facility simultaneously and provide two transmit
pairs out each of the four T-1 ports. Both T-3 Monitor ports
on the unit are designed to access the T-3 transmit and receive
signals through a DSX3 jack panel. The TL5140 T-3 Dechannelizer
includes a 20 dB amplifier on each of the T-3 Monitor ports
which enables the unit to recover the attenuated T-3 signals.
Pass Through Mode
In cases where a DSX3 patch panel is not present, the TL5140
has a Pass Through mode. The Pass Through mode consists of
four BNC connectors on the rear of the unit. Two BNCs are
for the transmit T-3 signal and two are for the receive T-3
signal. The two transmit BNCs are wired directly to each other
and pass through the unit. The receive BNCs are wired in a
similar fashion. Internally , 750 ohm resistors are tapped
onto each pass through signal similar to the monitor jacks
on a DSX3 patch panel. The other side of these resistors are
attached to the 20 dB amplifiers where these transmit and
receive signals can be monitored by the TL5140.
