PDR bridge is a high performance, remote self learning Ethernet bridge. Its compact size and
low cost make it ideal for cost-sensitive bridging applications, or as a LAN extender over bit
stream type infrastructures. Its E1 data interface also provides an economical digital access
solution for E1 and Fractional E1 network services, which can work at data rates of 64Kbps to
2048Kbps. User data is placed into the E1 frame, using only the required number of time slots.
Time slot assignment is accomplished according to the Data Port speed and manual setting of
DIP switches. The main E1 link may be clocked from the recovered receive clock from an
internal oscillator. For easy checking of any fault in the network, the device provides loop
selection, both local loop and remote loop. |
