• 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.
