DESCRIPTION
The 16-Port
Nx64-MUX is a modular TDM Multiplexer designed to support up
to sixteen sub-channel ports from 9.6Kbps to 768Kbps in both
Sync and Async formats. It is designed to work in a paired,
point-to-point configuration over a single synchronous composite
link from 64Kbps to 2.048Mbps. The unit is supplied with a variable
composite port rate from 64Kbps to 2.048Mbps in 64k increments
for maximum flexibility. The composite port data interface
is software selectable for RS-232, RS-530, V.35, RS-422/449
or X.21.
The sub-channel ports may be individually configured to support flow control
of RTS to DCD on a port by port basis or no flow control. The ports also support
individual RTS to CTS delays and external TXC timing for DCE to DCE crossover.
The data interfaces are RS-232 on 16 ports. Four of the user ports are software
selectable for RS-232, RS-530, V.35, RS-422/449 or X.21.
The Nx64-MUX derives its timing from the external DCE attached to the composite
port. Alternately, timing may be sourced by the Nx64-MUX in a direct cabled pair
of multiplexers.
The Nx64-MUX utilizes four, 4-port interface cards, a main processor card and
a power supply card. This modular design facilitates future upgrades and allows
the user to add user ports in 4-port increments. All cards are front load.
The management port allows local and remote configuration commands. Integral
software design features allow configuration of a sub-channel without disrupting
existing sub-channels. Network management features include channel and composite
loop backs, and link down error reporting. All port parameters are set with an
async terminal connected to the configuration port. Setup procedures are menu
driven and all parameters are stored in memory that supports power outages.
The Nx64-MUX has an internal power supply and supports voltages of 85-264 VAC.
The unit is 3-U high and is standalone or 19" rackmount. The factory warranty
is 3 years.
