Ethernet, data and voice range extension
The Optimux-34 and Optimux-25 provide a
simple and cost-effective solution for
transporting multiple E1 or T1 links, as well as
data or Ethernet, for distances up to 110 km
(69 miles).
Optimux-34 supports up to 16 E1 channels,
while Optimux-25 supports up to 16 T1
channels. A single 10/100BaseT Ethernet user
port is optional. The bandwidth available for the
Ethernet port can be adjusted by the user in
gradations of 8 or 6 Mbps. The configuration
options are:
• 16 E1/T1 only
• 12 E1 and 8.448 Mbps for Ethernet
• 12 T1 and 6.176 Mbps for Ethernet
• Eight E1 and 16.893 Mbps for Ethernet
• Eight T1 and 12.352 Mbps for Ethernet
• Four E1 and 25.334 Mbps for Ethernet
• Four T1 and 18.528 Mbps for Ethernet
• 32 Mbps for Ethernet only (Optimux-34)
• 25 Mbps for Ethernet only (Optimux-25)
The main link interface of the Optimux-34 can
be either a standard coax E3 interface or a fiber
optic interface. In the Optimux-25, only a fiber
interface is available.
The following optical interfaces are available:
• 1310 nm and 1550 nm laser for extended
range over single mode fiber
• 1310 nm and 1550 nm long haul for
extended range over single mode fiber
• Single mode over single fiber (WDM) option
Multiple Ethernet transmission options
Ethernet transmission utilizes a single integrated
10/100BaseT LAN port. The Ethernet port can
operate in half or full duplex mode, and
supports auto-negotiation and transparent VLAN
forwarding. IEEE 802.3x flow control and
backpressure are also supported.
Power supply redundancy
The Optimux-34 and Optimux-25 offer modular,
redundant power supply and secondary link
options, enhancing system reliability. The
optional secondary link provides backup using
automatic switchover upon main link failure.
The Optimux-34 and Optimux-25 devices
transmit each of the E1 or T1 tributary channels
independently. The E1 interface can be 75 Ω
unbalanced or 120 Ω balanced. The T1 interface
is 100 Ω balanced.
The E3 interface clock in the Optimux-34 can be
locked onto an external station clock.
Diagnostics and management
To facilitate system diagnostics, both products
feature LED status indicators, AIS alarm
generation and recognition and dry contact
closure upon link failure. In addition, setup,
control and diagnostics can be performed
through a supervisory port using an ASCII
terminal, Telnet host or Web terminal, or from
an SNMP management station via the Ethernet
port or the dedicated management port
(Ethernet or RS-232).
The SNMP management application offers:
• RADview for Windows env ironment
• RADview for HP OpenView UNIX platforms
The Optimux-34 is available as a compact
1U-high or 2U-high (E1 unbalanced only) unit,
while the Optimux-25 is a 1U-high unit.
