Overview
The device F4-51 Network Bridge is a high performance,
remote, self-learning Ethernet bridge. Its compact
size and low cos t
make it ideal for cost-sensitive bridging applications,
or as a LAN extender over bit stream type infrastructures.
Its E1 data interface also provides an economical
digital access solution for E1 and Fractional E1 network
Services, which can work atdata rates of 64Kbps to
2048Kbps.User data isplaced into the E1 frame, using
only the required number of timeslots. Timeslot assignment
is accomplished according to the Data Port speed and
manual setting of DIP switches. The main E1 link may
be clocked from the recovered receive clock or from
an internal oscillator. For easy to check the fault
of network line, the device provides loop selection,
both local loop and remote loop.
