70Mbps over telephone pair

TELNET’s VC 500-IB module is based on VDSL technology and maximizes the capacity of conventional telephone loops, offering asymmetrical bandwidths in access applications to IP networks or point-to-point connections. This module can be installed on MicroSAE (1 slot), TriSAE (3 slots) and MiniSAE (12 slots) chassis.

The VC 500-IB module’s VDSL technology extends the life-cycle of copper infrastructure, while at the same time facilitating the provision of broadband services in areas where optical fiber has not been installed.

The VC 500-IB has all of the capabilities of TELNET’s line of Broadband Access solutions:  

• Master and slave operation. Any VC 500-IB can work interchangeably as MASTER (installed in MiniSAE) or SLAVE (installed in MicroSAE or TriSAE). The configurations established in the MASTER (speed, negotiation, etc.) force the functioning of the SLAVE
• Remote management of the device. Both modules can be managed with a single IP that comes pre-configured: MASTER and SLAVE. End users can’t access MicroSAE or TriSAE management (SLAVE units)
• Link management. From the MASTER, a TEST can be initiated to check the status of the telephone loop that connects to the client
• Error propagation. If a fault occurs at any of the following points, the LOS (Loss of Signal) event is propagated in order to enter Spanning Tree service:
  • FastEthernet cable or interface involved in the connection of the client network and the VC 500-IB module
  • Telephone loop involved in the client link with MiniSAE;
  • Cable, fiber, and interfaces existing on the MiniSAE connection with plant switch

TELNET’s VC 500-IB solution also allows connections between two locations where telephone cable is available. In these cases, it significantly simplifies the interconnection of centers where the installation of UTP or fiber-optic cable is not feasible for economic or technical reasons.
