DESCRIPTION
• FCD-E1M and FCD-T1M serve as
access multiplexers, to provide
business customers with modular
integration of voice and data
traffic over E1/T1 or Fractional
E1/T1 services (see Figure 1).
• The units also operate opposite
RAD's modular DXC multiservice
access node or other vendors'
E1/T1 equipment, for multilink
star applications, such as access to
SDH networks. The DXC and FCD
units operate together with
centralized SNMP network
management (see Figure 2).
• The devices can be ordered with a
copper E1/T1 or a fiber optic link.
Both configurations are also
available with an optional copper
sub-E1 drop-and-insert port. The
units include a single data port, or
an Ethernet bridge with or without
VLAN support, or an Ethernet
router.
• FCD-E1M and FCD-T1M include
a single I/O module slot that
supports one Megaplex I/O
module. This provides field
upgrade and service profile
change capabilities that are
usually available only on larger
modular devices. For supported
module details and ordering
information, see individual
module data sheets.
