• The IR-ETH/QN port is available
with a 10/100BaseT interface. The
other Ethernet port options are
available only with a 10BaseT
(UTP) interface.
• The optional four ISDN "S"
interfaces can extend ISDN
services to locations that do not
support ISDN. Each "S" interface
port operates in full-duplex mode
over a 4-wire twisted-pair at a
range of up to 1000m (3300 ft).
• The optional IBE backup interface
can automatically back up the
data port over switched ISDN
networks.
• The optional sub-E1 port can be
configured to work without
CRC-4, while the E1 main link is
working with CRC-4. This allows
non-CRC-4 E1 equipment to be
connected over an E1 network
that is using CRC-4.
MANAGEMENT & MAINTENANCE
• Status and diagnostic information
is defined, configured, and
monitored using one of the
following methods:
Menu-driven management using
the front panel LCD with three
pushbuttons.
ASCII terminal connected to the
SLIP control port
SNMP or Telnet management
through either the SLIP control
port or inband
• The internal SNMP agent can be
controlled by the RADview SNMP
network management application
or any generic SNMP station.
• FCD-E1A supports both dial-in
and dial-out modem connections.
These connections allow remote
out-of-band configuration and
monitoring, as well as sending
callout alarm messages. Modems
can be connected using the serial
V.24 SLIP, PPP, or Ethernet ports.
• Inband management uses the
spare bits (S
a
bits) on timeslot 0
(TS0) or a dedicated timeslot with
standard protocols: Frame Relay
(RFC 1490), PPP, and standard
RIP2 routing. If spare bits on TS0
are used for management access,
they must be passed transparently
end-to-end.
• Maintenance capabilities include
user-activated local and remote
loopbacks on the E1 main link,
sub-E1, and data ports. The user
can activate a BER test for each
data port individually.
• Each data port responds to an
ANSI FT1 inband loop code (RDL)
generated by a remote FCD-E1A
or DXC in a specific bundle of
timeslots allocated only to that
port.
• E1 network statistics are stored in
memory according to RFC-1406
and can be retrieved locally
through the control port.
