1.0 Introduction
The FRM301 is a 3U high 19" Rack, 16 slot modular media converter center. The
FRM301 provides an economic solution in high density Fiber Converter installations
such as central offices. The Power Modules are designed for redundant power
supply operation. An additional feature allows the FRM301 to detect the working or
failing status either of power module or any fan assembly in the unit. There are 16
slots available for installation of FIB1 Converter Cards in the FRM301 compact rack.
An optional SNMP Card may be installed, for local and remote management
purposes. Each FIB1 Card is an independent fiber to copper converter. A variety of
cards are available that support multi-mode or single-mode fiber types and
connections to SC, ST, LC or MT-RJ or even the latest WDM (Wave Division
Multiplexing) in ranges from 2Km to 120Km. Converter cards include Fast Ethernet,
Gigabit Ethernet, Serial (RS-485, RS-423, RS-232 and TTL), E1, T1, and Datacom (V.35,
RS-530, X.21, RS-449, and RS-232).
1.1 Functional Description
The FRM301 optionally incorporates a redundant Power Module and SNMP.
The supply, depending on the model, derives its power from either an AC power
source (90 ~ 264VAC) and/or DC (18 to 56VDC) power source. When two modules
are installed, they provide for power redundancy and are hot swappable even during
the FIB1 Cards' transmissions. The FRM301 provides all copper interface connections
on the face of each FIB1 Card. The fiber interface connectors are also located on the
individual FIB1 Card's face, along with status indicator LEDs and any required
control switches. The status LED indicators provide for quick indications of both
copper and fiber link statuses.
