Manufacturer:STM Description:The UTOPIA interface [1. See Section 21.0 References] is an established standard for connecting Physical Layer de- vices to ATM Layer devices. However, when the ATM Layer device and the Physical Layer device(s) are on separate cards within a piece of equipment, or even on separate equipment, then the parallel nature of this standard becomes a limiting factor. See Figure 2. The solution is to use the VCX162245, which is a transparent bridge that extends the UTOPIA bus over a serial LVDS interface, and is suitable for backplanes and cables. Full bidirectional flow control is incorporated, allowing back- pressure to be applied to the source of the ATM cells. The 31 PHY ports available with standard UTOPIA Level 2 may be extended to 248 ports without additional external circuitry. The VCX162245 achieves this by providing as many as 8 ENB and CLAV signals in both receive and transmit direc- tions when acting as the ATM Layer device. This allows addressing 248 PHYs that are configured as up to 31 ports that each have as many as 8 sub-ports. |
