DSLAM Huawei MA5616 128Port


دستگاه دی اسلم در مراکز ارائه دهنده سرویس DSL نصب و امکان ارائه خدمات مبتنی بر DSL را فراهم می نماید. این سخت افزار خارق العاده از تجهیزات شبکه به نام DSLAM ، اتصالات مربوط به تعدادی از مشترکین را گرفته و آنها را به یک اتصال با ظرفیت بالا برای ارسال بر روی اینترنت تبدیل می نماید.

دستگاههای DSLAM دارای انعطاف لازم در خصوص استفاده از خطوط DSL متفاوت ، پروتکل های متفاوت و مدولاسیون متفاوت ( Cap;DMT ) می باشند.

در برخی از مدل های فوق امکان انجام عملیات خاصی نظیر اختصاص پویای آدرس های IP به مشترکین، نیز وجود دارد. یکی از تفاوت های مهم بین ADSL و مودم های کابلی ، نحوه برخورد و رفتار DSLAM است . کاربران مودم های کابلی از یک شبکه بسته بصورت اشتراکی استفاده می نمایند.

در چنین مواردیکه همزمان با افزایش تعداد کاربران ، کارآئی آنها تنزل پیدا خواهد کرد. ADSL برای هر یک از کاربران یک ارتباط اختصاصی ایجاد و آن را به DSLAM متصل می نماید. بدین ترتیب همزمان با افزایش کاربران ، کارآئی مربوطه تنزل پیدا نخواهد کرد.

وضعیت فوق تا زمانیکه کاربران از تمام ظرفیت موجود خط ارتباطی با اینترنت استفاده نکرده باشند ، ادامه خواهد یافت . در صورت استفاده از تمام ظرفیت خط ارتباطی اینترنت ، مراکز ارائه دهنده سرویس DSL می توانند نسبت به ارتقاء خط ارتباطی اینترنت اقدام تا تمام مشترکین متصل شده به DSLAM دارای کارآئی مطلوب در زمینه استفاده از اینترنت گردند.

Provides lightning protection and anti-interference functions.

Starts up at -25°C.
Endures high temperatures and it operates efficiently at 65°C (the maximum working temperature).
Supports the temperature detection function. When the temperature exceeds the threshold; the system will generate an alarm.
Supports protection of the subscriber port:
DSL port: enhanced K20; common mode 4 kV
POTS port: common mode and differential mode; 4 kV
Supports the power protection (2 kV in differential mode and 4 kV in common mode).
In the AC + backup power configuration; the battery can be used as the backup power. When the AC power supply fails; the battery supplies power to the system. In this case; the broadband services are shut off; and the narrowband services are normal.
Supports the intelligent speed adjustment of the fan. The system can automatically adjust the fan rotating speed according to the working temperature; which ensures noise reduction and that this unit is a reliable energy saving solution.
Supports replacement the fan tray independently.
Adopts the derating design for the electronic components to improve the reliability.
Provides the corrosion-proof design and reduces the cable routing on the board surface.The heat dissipation layout is reasonable (to prevent the condensation from forming because of the temperature difference).
Supports the MGCP/H248/SIP dual homing. When the MGCP/H.248/SIP protocol is used; the MDU can be configured with up to two MGCs. When the MGC is switched over or the MDU detects the fault of the primary uplink; the system automatically switches to the other MGC.
Supports emergency standalone. When the MDU upstream port is interrupted; the system automatically starts the emergency standalone function. Then; the subscribers of the same MDU can call and communicate with each other.
Supports virtual noise. The system uses the virtual noise mechanism to decrease the line rate (the system adjusts the line rate according to the SNR); which improves the antiinterference capability of the system.

High and Guaranteed QoS

The MA5616 has a high and guaranteed QoS; which lays the foundation for service management.

Traffic-stream-based priority marking
ACL-based priority marking
Three scheduling modes; namely priority queuing (PQ); weighted round robin (WRR); and PQ+WRR
DBA-based bandwidth management of the GPON port
Mapping upstream/downstream services to different priority queues for scheduling based on the priority
ACL-based access control
Two rate three color marker (trTCM)-based IP traffic profile; and rate limitation on a subscriber port
TCONT-based priority service in the upstream GPON transmission direction of the MDU.

System Security

Filters the packets by specified IP address; port; and protocol type.
Filters the packets by the source MAC address and destination MAC address of the packets.
Filters the packets by the source route options.
Supports ACL-based (allow/deny) access control.
Supports static binding of the MAC addresses.
Supports suppression of broadcast; multicast; and unknown unicast packets of the GPON port Ethernet port.
Supports SNMPv3 on the basis of SNMPv1 and SNMPv2c. Provides three key services; namely; authentication; encryption; and access control; considering the security defect in SNMPv1 and SNMPv2c.(Note: The device on the CO side must also support SNMPV3.)
Supports changing the password for the Root user.
Supports GEM port-based encryption through the PLOAM messages in the downstream direction; by using the Advanced Encryption Standard (AES) 128 encryption algorithm.
Supports dynamic key switching based on ITU-T G.984 through the PLOAM messages.
Supports dual GE port (backup for each other) upstream transmission.
Supports the virtual MAC (VMAC).
Supports anti-ICMP/IP attacks.
Supports setting the anti-DOS attack function through the CLI and NMS.

Subscriber Security

Supports L2 isolation and controlled mutual access of the subscribers
Supports the global Policy Information Transfer Protocol (PITP) and the PITP controlled by VLANs
Supports global DHCP Option82 and the DHCP Option82 controlled by VLANs
Supports DHCP Option82 so that the information about the physical location of a subscriber is contained in the authentication packet; thus enhancing the DHCP security
Supports global-level dynamic anti-MAC address spoofing. After the subscriber passes the authentication; the MAC address of the subscriber is bound with the service stream dynamically.
Supports the global and VLAN-level anti-MAC address spoofing and anti-IP address spoofing based on the DHCP protocol.
Supports the anti-MAC address spoofing function for the subscriber who uses the PPPoE protocol.
Supports the management of the operation rights of the maintenance and management personnel according to different right levels

Multicast Protocol

Internet Group Management Protocol (IGMP) V2 and IGMP V3
IGMP proxy and IGMP snooping

Multicast Service

Up to 32 multicast VLANs and 1024 programs for each multicast VLAN
1024 multicast groups
Up to 16 multicast groups that the subscribers under each service port can join concurrently
Delay shorter than 50 ms for joining or leaving the multicast group
Flexible and easy channel control
IGMP packet statistics
High performance processing of IGMP packets; which enables the broadband TV (BTV) service
Multicast VLAN; program; and subscriber management
Setting and querying the quick-leave function through the NMS or the CLI
Global-level switching of IGMP modes
Filtering downstream multicast packets (The downstream multicast traffic that is not contained in the multicast filtering table is discarded.)
