FCD-IP
E1/T1 or Fractional E1/T1 Access Unit with Integrated Router

Integrated accessdevice providing
bundled services
over E1/T1 accesslines• Provides bundled services (data, IP, and telephony) over E1/T1 access lines• E1/T1 uplink over copper or fiber optic media• Operates opposite RAD's DXC cross-connect system and Megaplex access
multiplexers• Supports Frame Relay, PPP, and MLPPP

FCD-IP is an E1/T1 or fractional E1/T1
integrated access device (IAD), whichenables service providers to bundle data,voice, and IP access services over a single
E1 or T1 access line (see Figure 1).

Supported WAN services are:•T1 or fractional T1 CSU/DSU operating
at rates of up to 1.544 Mbps

•E1 or fractional E1, with or without
LTU, operating at rates of up to 2.048
Mbps•

E1 or T1 over fiber optic links•

Frame Relay with auto-learn of DLCIand maintenance protocol•

ISDN BRI (“U” or “S” interface) fordata services backup.

The Access CompanyFCD-IP
E1/T1 or Fractional E1/T1 Access Unit with Integrated RouterAn integrated router supports IP routing
and transparent bridging.

•Single IP address translation thatallows a small or medium office LAN toconnect to the Internet using a single
dynamically or statically allocated IPaddress•DHCP server that allows the sharing ofISP address pools between DHCP
clients on the LAN.

•OSPF protocol based on the link statetechnology, distributing information
about the state of links betweenrouters.

An optional internal 4-port Ethernet/Fast
Ethernet switch can be installed in placeof LAN ports.
Internet/intranet access capabilities areenhanced through:•IP Service Access authentication
provided by PAP/CHAP•

Solid Firewall that protects an office
LAN from undesired entry from theInternet•

NAT that allows the sharing of several
legal IP addresses between the variousLAN users

The sub-E1/T1 or quad analog voicedrop-and-insert ports provide toll-quality
voice transmission. Up to three sub-E1/T1
ports can be installed in FCD-IP,
aggregating three fractional E1s into one
full E1 stream (see Figure 2).

In the ring (Figure 3) and daisy-chain andshared LAN applications (Figure 4), thefirst sub-E1/T1 port (sub1-E1/T1) can beused as a main link. In this case some ofthe E1/T1 timeslots pass through internalrouters of all FCD-IP devices used in theapplication. The other timeslots are
dropped at the user interfaces (FXS,
remaining sub-E1/T1 ports etc). This
enables the units to drop and insert
timeslots and take routing decisions at
any FCD-IP.
Notes: The sub1-E1/T1 port cannot be defined as amain link if FCD-IP includes a DTE data port, twoLAN ports or ISDN ports.
FCD-IP connected to two LANs cannot be used in
the ring applications.

The fail-safe bypass of the sub1-E1/T1 linkensures the continuity of voice services incase of power supply failures. The bypass
is not available for the fiber optic mainlinks.
ISDN or PSTN backup, using an external
dial-up modem, ensures the continuity ofdata services.

Figure 1. Bundled Services

Data Sheet

An optional data port can be utilized
either as a second serial router port or asa transparent n × 64, n × 56 data port forconnecting legacy equipment.

The dual-level management authentication
allows user access to router configuration
parameters, while restricting user accessto network configuration parameters.

The unit can be easily configured througha quick setup menu using a terminal
attached to the control port or by Telnet
access over the LAN/WAN.

Software download is available via thecontrol port using XMODEM and via
LAN/WAN using TFTP.

FCD-IP features a variety of inband andout-of-band management options. Theseoptions include dedicated timeslot,
dedicated DLCI and dial-in.

Parameter file download and upload isavailable via LAN or WAN using TFTP.

The SNMP agent provides management byRADview or any other standard SNMP
management station.
Undesired access to FCD-IP via Telnet or
SNMP can be blocked or password
protected.
