  • * Numerous interfaces
  • * Flexible use in IP networks and PDH/SDH networks
  • * Support of different transmission protocols


Centralized Future Proof Architecture

The Atrie Chassis MSAN 4800 Series- 4817/4812/4806, are equipped with non-blocking Gigabit backplane, failover-enabled Management Switch Cards (MSCC), dual input power modules and various high-port density multi-purpose line cards. With comprehensive IP-centric firmware features, the Atrie Chassis MSAN is a high-capacity system that facilitates telcos/ ISPs to deliver high-quality residential or business user services experience at competitive CAPEX/OPEX as well as satisfying its current and future infrastructural requirements of reliability, flexibility and scalability.

Easy & reused logistics

The Atrie Chassis MSAN has various chassis with different height and slot quantity. All management card share the same attributes of their predecessors and are IPv6 hardware ready. The variety of line cards is including 72-port ADSL2+ line card that provides subscribers with asymmetric transmission bandwidth up to 25 Mbps/2.4 Mbps; 48-port SHDSL line cards with symmetric transmission bandwidth of 5.69 Mbps per port; 24-port and 48-port VDSL2 line cards that offer up profile 30a (100/100 Mbps) highspeed connectivity per port over copper wires; 20-port fiber-based Gigabit Ethernet line card that supports 100/1000 Mbps transmission speed per port. The new 48-port ADSL2+/VoIP combo card with built-in ETSI/ ANSI POT splitter can be managed by the new ATR-4800 MSCC Management Switch Signaling Card. ATR-4800 MSCC 10G and ATR-4800 MSCC 1G are able to support IP aggregation for all the combo cards in the same chassis

Advanced Triple Play and mass deployment functionality

The Atrie Chassis MSAN inherits all the Layer 2 and Layer 3 QoS, security and multicast functionalities, while the following new features are added to satisfy the requirements for massive field deployments: (1) IP bridge functionality that alleviates the Layer 2 access network deployment restrictions resulted from MAC address table limitation and security attack issues; (2) ARP Proxy which minimizes the ARP broadcast requests to all subscribers; (3) TACACS+ mechanism to support remote authentication with TACACS+ servers; (4) VLAN-aware DHCP snooping which adds VLAN information into DHCP snooping tables; (5) DHCP option 82 sub-option 2 for providing remote client ID information to DHCP servers for flexible IP address assignment.

Robust physical safety design

The MSAN 4800 Series 4817 and 4812 support 1+1 MSC redundancy with a failover switching time less than 1 second. In addition, voltage, temperature and fan speed sensors are fitted into the system. When an abnormal condition is detected, the LED displays and/or the corresponding alarms will alert administrators of the situation. In case the system temperature rises over the preset threshold, thermal cutoff protection will kick in to shut down the system automatically.

Sophisticated OAM&P features

The Atrie Chassis MSAN provides various management methods: local console port, Web-based configuration, Telnet and SNMP v1/v2c/v3-based EMS (TOPView EMS). The management functions include Alarm and Status Surveillance, Configuration Management, Performance Management and Fault Management. The Atrie Chassis MSAN allows multiple administrative accounts with access privileges. TOPView EMS also provides view-based MIB management that partial MIB objects can be defined and accessed for customization and security reasons. In addition, HTML/PDF/XML-based northbound interface is equipped to interoperate with external OSS systems.

Environment-friendly two-way airflow for cold-hot aisle telecommunication rooms

The MSAN 4800 Series fan module supports two-way — back-to-front and front-to-back — airflow, so users can switch the direction according to different telecommunication room layouts. As cold-hot aisle telecommunication rooms enjoy better air cycle and cooling efficiency, they save electric bills by better utilization of the air-conditioning systems.
