4.3 The EDN424 HDSL IP DSLAM
The EDN424 is a 24-port IP DSLAM in the EDA solution. EDN424 is an
environmental hardened, 1U high mini-DSLAM that aggregates 24 SHDSL
lines to one 100 Mbps Ethernet. Design flexibility enables the EDN424 to
be mounted as rack, wall or vertical positioned units inside an existing
closure.
Downlink and Uplink ports
EDN424 offers 24 SHDSL downlink ports, each supporting symmetrical
bandwidth of up to 2.3 Mbps for single pairs and 4.6 Mbps in 4-wire mode.
Future upgrade will enable 5.7 Mbps per pair according to SHDSL.bis. The
uplink aggregates the 24 ports to 100 Mbps Ethernet. Management.
The Public Ethernet Manager (PEM) is the element manager for EDN424.
A customized management VLAN is terminated in the EDN424 to enable
remote management of the unit. The northbound interface of PEM offers
generic interfaces, such as CORBA and SNMP, enabling use of the same
provisioning and management system already employed in the operator’s
network.
Services
EDN424 enables the operator to offer a wide range of services:
• Telephony over IP (ToIP) to the end-users
• Data services as either fixed bandwidth or bandwidth on demand, with
the possibility of using the existing PPP authentication
