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.
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 supports redundant power supplies
with system notification via optional chassis. The unit is
3-U high, or 5-U high and is standalone or 19” rackmount.
The factory warranty is 3 years.
