AXXESSIT offers a family of products to build broadband service integrated access network infrastructure for operators serving enterprise customers. AXXESSIT prod­ucts cover the same services via fiber, radio or copper.
The AXX155 is an Integrated Access Device (IAD) in the AXXESSIT Rainbow family to provide real broadband solutions (2Mbit/s or higher). This product will aid the converging process from circuit-switched to packet-switched services. AXX155 combines IP- and TDM-traffic in a cost effective way, by running IP-along with TDM-channels inside an SDH-frame that can easily be carried across the network. The bandwidth of the IP-channel is configurable up to 1 DDMbit/s true "wire speed". The AXX155 is designed to facilitate interfacing with IP and TDM equipment from other vendors. All interfaces are based on open standards.
An element manager application called AXXTMN is provided for remote super­vision of AXX155 devices. AXX155 also provides a simple VT100 command line interface (CLI) or a powerful craft tool, AXXCRAFT, for local management of the unit.
Software upgrades can be done remotely from a CLI terminal or AXXTMN.

Main product features
 • Ethernet interfaces with support of Layer 2 bridge/ switch. 
 • Flexible support of TDM- and IP-traffic, both TDM-and IP-traffic is mapped into SDH VC-12 containers.
 • Different IP bandwidth is obtained by using a number of VC-12 containers in an inverse multiplexer scheme.
 • STM-1 standard aggregate interface compatible with OH- and VC-termination, performance monitoring and path trace
    termination.
 • STM-1 e electrical aggregate interface. 
 • Fractional STM-1 supported. Full VC-12 granularity.
 • Synchronization of the unit can be taken either from the optical interface, 2Mbit/s interface, a dedicated synchronization
   input or the local oscillator.
 • Link protection by duplication of optical- or electrical interface.

FEATURES

LAN interfaces
 The Layer2 bridge (switch) is a transparent remote multi-port Ethernet bridge. The bridge consists of four LAN inter­faces and one WAN interface. The LAN interfaces supports 10/100 BaseT for UTP cables. Both lQMbit/s and 100Mbit/s are supported with auto-negotiation. The bridge supports automatic learning/aging and the Spanning Tree algorithm. Standard VLAN is also supported. The filtering rate of the bridge is able to operate at full wire speed, but the forwarding rate is limited by the selected WAN channel speed.
TDM interfaces
  The AXX155 has four physical interfaces that support transparent data (G.703) and ISDN PRA. All four interfaces can be configured individually. The interfaces support 120 Q. operation. 75 Q. operation is supported by use of an external balun.
WAN interface
  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 of the system. Different WAN speed can be achieved by a proprietary flexible mapping scheme. The IP-traffic is mapped into one VG-12 container or a number of VG-12 containers. The AXX155 supports several different optical interfaces, a standard dual fiber interface (S-l.lj for single mode fiber and multi mode fiber, a long haul fiber interface and a proprietary single-fiber interface. The reach of the S-l.l interfaces can be up to 25km depending on fiber quality (12dB optical budget). Two aggregate interfaces can be used for protection. Protection scheme is MSP 1+1.
Management
  The AXX155 is equipped with an SNMP agent that supervises both the LAN- and TDM-ports. The SNMP agent sup­ports a number of standard MIBs and an AXX155 specific MIB. An element manager application called AXXTMN is provided for remote supervision of AXX155 devices. AXX155 also provides a simple VT100 command line interface (GLI) and a powerful craft tool, AXXGRAFT, for local management of the unit. In addition, the AXXEMEDIATOR can be launched to provide northbound integration to other OSS applications.
