Applications
The TC8800 is typically used to link or
extend data and telephone lines in campus networks. In many instances
the TC8800 can replace expensive channel banks.

Description
The TC8800 is a 4-to-28 channel telephone
and data fiber optic multiplexer that extends multiple telephone lines,
analog and
data channels to remote sites such as other buildings in campus networks. The TC8800 Series consists of TC8800 (FXS),
TC8801 (FXO), TC8802 (Data), TC8803 (4-wire Analog) and TC8805 (2-wire
Analog). Users can mix or match telephone channels, analog channels
or RS-232, RS-422, TTL, Dry Contact data channels in increments of
four up to a maximum of 28 channels. For example, a user could multiplex
20 telephone channels and 8 RS-232 data channels.
The TC8800 Series converts 2-wire FXS to fiber
optics on the telephone side with ring down capability and FXO on the PBX
side. Distances up to 80km are typical over single mode fiber, 4km over
multimode fiber. Because the TC8800 digitizes the analog signals (PCM),
voice quality does not degrade over extended distances.
It supports Telephone/Analog channels from 300Hz
to 3.4Khz and asynchronous data rates to 19.2 Kbps. Twelve LEDs are
available for status monitoring and diagnostics. A dry contact alarm is
optional. Diagnostic LEDs for each channel include Tx, Rx, Hook and
Ring.
The TC8800R PC Card version requires the TCRM191
or TCRM195 19" Rackmount Card Cage. Each
TC8800R card can be removed or installed on the TCRM191 without powering
down the system ("hot-swappable"). The TC8800S Standalone
version currently supports up to 8 telephone or data channels. An
extreme temperature version (-20°C to 70°C), TC8800T, is also available.
The TC8800 Series works with all types and sizes
of multimode or single mode fiber optic cable at 850/1300/1550nm. Fiber
optic connectors are ST, SC or FC. RJ-11F ports are provided on the rear side
to connect with telephones, analog and data devices. Power redundancy is
standard; optical redundancy is optional. Power is 12Vdc; 24VDC, -48VDC,
125VDC or 115/230VAC
are optional.
