Gateway
Next Generation
DSL Functions
The ADSL Access Module (AAM) in MSAP2000 provides
complete IP DSLAM functions.
One module of AAM provides 12 ADSL2/2+ ports, and complies
with ITU-T G.992.1, G.992.2, ANSI T1.413 issue 2, ADSL2
(G.992.3, G.992.4), ADSL2+(G.992.5) and ITU-T G.994.1.
Ethernet over SDH
MSAP2000 integrates SDH STM-1 ADM functions. Apart from
providing interfaces for traditional E1 subscribers, it also supports
ITU-T G.7041 and ITU-T X.86 compliant Ethernet over SDH (EoS)
functions, for provision of next generation IP broadband services.
Cross-connection &
Grooming
MSAP2000 incorporates the Time Slot Interchange (TSI)
technology. Any input/output port in either the COT or RT can
cross connect at 64 Kbps. Any input/output port at the RT side
can use a 64 Kbit/s time slot basis, to cross connect to any E1
interface on the COT network, to form an E1 signal.
Packet Switch
Apart from TDM Switch (TSI) functions, MSAP2000 also provides
Packet switch functions, which support IP network switching
functions, such as IEEE802.1d STP, 802.1p, Port-based &
tag-based VLAN and Static MAC address filtering.
Hybrid Optical
MSAP2000 simultaneously supports two different types of Optical
Trunk Interfaces: SDH STM1/4 and Gigabit Ethernet. All user
interfaces may connect to the COT via a SDH TDM network, or
they can connect to an IP network via a Gigabit Ethernet Packet.
Flexible Topology
MSAP2000 supports various types of network topologies, such as
Point to Point, Star, Linear, Tree and Branch, Ring. Moreover,
MSAP2000 support both single end and two end configuration to
provide service on access network.
Redundancy
Protection
All of MSAP2000’s Common Modules are equipped with
Redundancy functions (1:1, N+1, N:1), to provide double
efficiency and stability during system operation. The 99.99%
in-service quality can be assured. The following modules come
with redundancy functions:
