MODEL: AXX155E

Main benefits 

 Price/performance :
   AXX155E will provide a powerful and cost effective way to drive an evolution from service-dedicated, circuit-switched narrowband networks, to service-inte­grated, packet-switched networks.

 Flexibility:
 Many applications covered by one unit.
   - Point-to-point
   - Point-to-multipoint
   - Multipoint-to-multipoint
   - Bandwidth allocation per LAN port for multi-tenant units
 Granularity:
    Provisioning of IP bandwidth is obtained by using a number of VC-12 containers (1 to 50) in an inverse multiplexing scheme. All G3 VC-12 containers may be used for IP traffic if more than one WAN channel are used.
 Density:
   AXX155E is only 1U high, providing great port density per rack.
 Protection:
   Link protection possible by duplication of optical - or electrical aggregate interface.
 Operation/Maintenance:
   An SNMP agent supervises both the LAN and TDM ports. This agent can be accessed either by means of a CLI, Command Line Interface or from a JAVA application.

Interfaces

Features

 LAN interlaces
   The Layer 2 bridge (switch) is a transparent remote multi-port Ethernet bridge. The bridge consists of four LAN interfaces and up to four WAN interfaces. The four WAN interfaces are not only enabling the point-to-multipoint function, but also "QoS on Layer 1". The LAN interfaces supports 10/100 BaseT for UTP cables. Both 10Mbit/s and 100Mbit/s are supported with auto-negotiation. The bridge supports the following features:
    - MAC multicast
    - Full IEEE 802.1q VLAN tagging
    - Spanning Tree Protocol (STP)
    - Rapid Spanning Tree Protocol (RSTP) acc. to IEEE 802.1w
    - Tunneling of IEEE 802.1q packets (QinQ)
    - STP per VLAN acc. to IEEE 802.1s
    - IEEE 802.1p priorities
   The filtering rate of the bridge is able to operate at full wire speed, but the forwarding rate is limited by the selected WAN channels speed, up to 136Mbit/s.
   The hardware platform can be upgraded by SW download to support IP and IPX routing, with the below routing protocols:
   - RIPvl and RIPv2 
   - OSPF
  Layer 2 and Layer 3 QoS and multicast routing (IGMPv2) are also included. Full wire speed routing is possible, again, only limited by the selected WAN channel speed.

TDM interlaces
   The AXX155 has twelve physical interfaces that support transparent data (G.703) and ISDN PRA. All twelve interfaces can be configured individually. The interfaces support 120 Om. operation. 75 Om operation is supported by use of an external balun.

 WAN interlace
   The WAN interface is SDH based and the IP-traffic is mapped into SDH containers together with TDM-traffic for transport to the other end system. Different WAN speeds can be achieved either by a proprietary flexible mapping scheme or by Virtual Concatenation with Generic Frame Protocol (GFP) and LCAS. The IP-traffic is mapped into one VC-12 container or a number of VC-12 containers. The AXX155E supports several different optical interfaces, a standard dual fiber interface (S1.1) for Single Mode fiber and Multi Mode fiber, a Long Haul optical interface and a proprietary single-fiber interface. As option the optical interface can be replaced by an electrical STM-1e interface. Two aggregate interfaces can be used for protection. Protection schemes are MSP 1+1 and SNC/I.
