Using the latest ADSL technology, DAS-3216 offers service providers a very 
cost-effective solution for immediate implementation of multiple services in 
private and public networks.   

DAS-3216 is one product of DAS-3216 series, it acts as a standalone IP-based 
DSLAM, which can concentrate and manage up to 16 ADSL lines. User can use 
local RS-232 CID and/or remote TELNET/SNMP to manage the DAS-3216 
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 DAS-3216 concentrates 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 DAS-3216 acts as bridge for the ADSL ports 
without enabling the VLAN-PVC mapping feature. DAS-3216 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. DAS-3216 supports 2 ATM PVC links for each ADSL 
CPE. 

 

 

 

 

 

Figure 1-1    DAS-3216 Front View 

As Fig 1-1 displays, in the front view of DAS-3216, there are several LEDs to 
indicate current system and link status and one 10/100 Mega Ethernet interface 
for uplink.   

The DAS-3216 can be managed via SNMP, but each DAS-3216 will cost one IP 
address, and the performance of the DAS-3216 will be little affected due to CPU 
usage for the SNMP agent processing.
