2.5. IP DSLAM
IP DSLAM
MSAP2000 supports IP DSLAM functions. The uplink to BBRAS
can be achieved by GbE module through FE or GE interfaces Its
AAM (ADSL Access Module) provides 12 lines of ADSL2/2+; one
shelf provides up to a maximum of 96 ADSL2/2+ interfaces, and a
single shelf supports both POTS and ADSL services. One
MSAP2000 system can provide up to 576 ADSL user interfaces
and 16000 MAC addresses. MAC address can be assigned to
individual port to support MAC anti-spoofing. VLAN setting can be
up to 1024 for PVC, individual port, IP source address and IP
destination. VLAN translation as well as VLAN stacking are also
supported. Ethernet bridging is realized by 802.1d standard and
link aggregation is done according to 802.3 a & 802.3.d while flow
control is designed based on 802.3x. STP, RSTP and MSTP are
supported in spanning tree and static IP address can be
supported as long as the setting in BRAS and in CPE are
identical. QoS based on 802.1p can be provisioned for
individual port along with VLAN, IP SA/DA, IP TOC/DSCP
parameters, which allows policing and shaping traffic by port.
DHCP as well as DHCP filtering can be enabled or disabled to
support access control list by order of port, MAC address, and IP
address. Multicast supports bridged mode with IGMP v1/v2
protocol and IGMP snooping enabled. Total number of multicast
group can suppress 256.
xDSL Functions
„ MSAP2000’s ADSL Access Module (AAM) supports ADSL
G.LITE, G.DMT, ADSL2, and ADSL2+.
L2 Switch

functions, including MAC filtering, 802.1q VLAN Tagging,
802.1p QoS with priority queuing, 802.1w RSTP, IGMP v1 & v 2
snooping, DHCP, SNMP v1 & v2 and RMON.
