TC8300 is a remarkably flexible one-to-four channel T1/E1 Fiber Optic
Multiplexer that is frequently used to link PBXs, Channel Banks,
Customer Premise Equipment and M13 Muxes to DSX-1 Cross Connects.
TC8300 is a 1 to 4 channel T1/E1 Fiber Optic Multiplexer that offers
several advanced features including extensive diagnostics, extra data
channels, management software, power and optical redundancy, jitter
removal and a replaceable Line Interface module.
It is available both multimode and single mode and is compatible
with all popular types and sizes of optic cable.
The standard loss budget is 15dB, higher budgets are optional.
Distances to more than 100km are possible with the single mode
1550nm option (34dB loss budget).
are extensive. Each channel
offers six LED indicators to ease installation and troubleshooting - one
each for RxD, Alarm, T1/E1 Signal Loss, BPV violations, Remote Loopback
and Remote Signal Loss. Individual
channels provide 4 DIP switches, accessible from the front panel, to
control settings for line code, line length, local Loopback or remote
Loopback. Dry contacts are
extra out-of-band data channels are intended for multi-purpose
communications. Up to eight
RS-232 channels are available in addition to the T1/E1 channels.
Four data channels are available if the Management Software Module is used. The out-of-band RS-232 channels
can be used for telephone service with the Model TC1900
"Quick-Talk" Phone Extender.
redundancy is standard; optical redundancy is optional.
Both provide automatic switchover in the event of failure.
The TC8300 is transparent to the framing format and supports all
applicable standards and line codes including CCITT G.703 and
AMI/B8ZS/HDB3 Line Codes. Line
distances from 0 to 655 feet (for connecting to DSX-1 cross connects) are
supported. Jitter is eliminated
because of a built-in elastic buffer and jitter attenuator.
is the Standalone/Wallmount Unit. The TC8300R is the PC Card
version that fits into TCRM191 or TCRM195
19" Rackmount Card Cages. Fiber
optic connectors are ST or FC. Input
power is 12VDC (standard); optional 24VDC, -48VDC, or 115/230VAC with
a built-in or external power supply.
Special four-position and two-position feed-thru detachable
terminals are provided for connecting the T1/E1 twisted pairs. An extreme temperature version (-20ºC to 70ºC), Model
