ABOUT THE IE-IMCV-E1-MUX/4
OVERVIEW
The IE-iMcV-E1-Mux/4 is a media converter that transports four
independent E1 lines over an existing standard 155Mbps-capable fiber
optic line operating at an effective rate of 150Mbps. A second SFP port is
available for a 1+1 protection mode. One serial link (RS-232) and one
Ethernet (10/100BaseT) connection are also multiplexed onto the fiber
link(s). Each of these communication channels is transported end-to-end
at full wire speed with very low latencies.
The serial link can be used for extending an independent RS-232 interface
to the remote POP (Points of Presence) location for use in managing or
controlling other devices at the POP and supports any data rate up to
120K baud. In addition, each unit also supports an RS-232 console port
for local configuration by technical support personnel. Both of these serial
links are used for end-to-end system management, fault detection
/isolation and system diagnostics. The remote serial offers serial only.
The IE-iMcV-E1-Mux/4 provides fault indications on the E1 and fiber links
resulting from real-time active faults. The equipment detects both E1 and
fiber LOS events as well as degraded E1 or fiber lines. The unit will
automatically forward AIS signaling to the remote unit after detecting an
LOS (Loss Of Signal) condition on any incoming E1 line. Severe receive
optical link failures will result in the automatic generation of AIS signaling
onto the E1 lines connected to the unit receiving the corrupted optical
signal.
In addition, CV (Code Violation) errors are detected on all incoming E1
lines and BER calculations for the optical line are constantly being
performed by circuitry within the unit's optical receiver. Error conditions
are displayed on the unit's front panel LED indicators and reported to
system management software (if equipped) where more detailed error
information can be displayed on the user's GUI (SNMP).
Systems equipped with 1+1 fiber redundancy can benefit from the
enhanced reliability of a protected fiber link and the system's ability to
automatically switch to the "best" fiber line should one line become
impaired or fail. This automatic switchover capability is designed to occur
rapidly (<50 milliseconds), minimizing data loss and system down time. In
addition, automatic switchover can be overridden; this allows the end-user
to force the unit to receive on a specific optical line if desired for testing.
NOTE: Some options require items that are sold separately, available from B+B SmartWorx.
