The BX21, the next-generation SDH Access Modem of AimBridges, enables true multi-service carrier-grade access network solutions for tomorrow's converged networks. The cost-effective terminal multiplexer integrates voice, leased line and packet transport on a compact platform. The system is designed for customer premises access as well as metro aggregation networks, furthermore it is very well suited as a transport device in the wireless infrastructure. The BX21 is optimized to provide unparalleled density and small size at low cost.
The BX21 has the following key features:
-
SDH interfaces: STM-1 interface enabling SDH carrier class transport
-
Access interfaces: E1 and Fast Ethernet
-
Hot-pluggable SFP module for flexible reach selection
-
Standards compliant Ethernet mapping via GFP and Virtual Concatenation and LCAS for Ethernet private line applications
-
Intuitive web-browser based user interface
-
Compact design measuring only 1RU high, 19" wide
-
Low power and low cost start configuration
Reduced capital and operational expenses
Capex and Opex reductions are the main benefits of the BX21:
-
Highly integrated architecture with all functions combined on a single low-cost box
-
The system is preconfigured to ease installation and simplify service turn up without the need for costly and trained staff
-
Convergence of data and voice combined with high integration density significantly reduces the amount of equipment; this results in considerable lower investment, installation, operational and maintenance costs
- Optimal bandwidth utilization and flexibility is guaranteed by data mapping using GFP, Virtual Concatenation and LCAS. The operator can allocate a specific amount of bandwidth per end user, in steps of 2 Mbit/s up to 100 Mbits/s
-
Hot-pluggable small form factor pluggable (SFP) modules for the STM-1 optical interface allows flexibility to select the required optical power budget and link distance
Integration in existing networks
The BX21 protects the investments made in the installed SDH network and improves the operator's TDM services and revenue through its higher integration and lower cost solution. In addition, the system supports effective Ethernet transport over the existing network without the need for costly deployment of an overlay network.
Management of the BX21 is easily integrated in an existing network management solution. The system provides an Ethernet management port for on-site craft maintenance. Remote management is via a dedicated VC12 and does not conflict with DCC channels already in use for existing network management. The TCP/IP stack and OSPF routing simplify management of remote BX21 systems from a single operations system.
The BX21 provides SNMP alarm traps as well as web-browser based provisioning.
