1.2 ADSL IP DSLAM Overview
Using the latest ADSL technology, ADSL IP DSLAM offers service providers a
very cost-effective solution for immediate implementation of multiple services
in private and public networks.
ADSL IP DSLAM can concentrate and manage up to 16 ADSL lines. User can
use local RS-232 CID and/or remote TELNET/SNMP to manage the ADSL IP
DSLAM directly
Since the ATM backbone coverage is not so general in the real broadband
network environment. Instead of traditional DSLAM system provides ATM
uplink interface, the ADSL IP DSLAM concentrates 8/16 ports of the ATM over
ADSL traffic which is encapsulated by ADSL CPEs, and maps each user’s
data encapsulated in ATM-PVC to Ethernet-with/without VLAN-tag packet
(depends on the VLAN was enabled or not for the specified ATM ports), and
then uplink to Telco or ISP directly, User can enable VLAN-PVC mapping
capability for each ADSL port independently. The ADSL IP DSLAM acts as
bridge for the ADSL ports without enabling the VLAN-PVC mapping feature.
ADSL IP DSLAM provides both Ethernet-VLAN and non-VLAN to ATM-PVC
mapping feature and bridge mode for the ISP to isolate user’s data with
security and to provide lots of service enhancement capabilities. ADSL IP
DSLAM supports 2 ATM PVC links for each ADSL CPE.
Figure 1-1 ADSL IP DSLAM Front View
As Fig 1-1 displays, in the front view of ADSL IP DSLAM, there are several
LEDs to indicate current system and link status and one 10/100 Mega Ethernet
interface for uplink.
The ADSL IP DSLAM can be managed via SNMP, but each ADSL IP DSLAM
will cost one IP address, and the performance of the ADSL IP DSLAM will be
little affected due to CPU usage for the SNMP agent processing.
As Fig 1-2 displays, in the rear-panel, there is one power adaptor, both -42V ~
-56V DC or 90V ~ 240V AC power module can be selected. There are two DSL
module slots, each module provides 8-port with built-in POTS-splitter ADSL
module, totally 16 ADSL CPE users can be supported in one ADSL IP DSLAM.
