Quasar-16RPCX-LP 16 ports low profile PCI-e/E1 adapter

Main Features
  • Number of ports E1 - 16 (reception only)
  • 16 E1 framers with CAS/PRI/SS7 signaling support
  • DMA mode for transferring data to computer memory without CPU involvement
  • Automatic selection of the synchronization channel
  • High-impedance version without terminating resistors
  • low profile PCI express x1 form factor
  • Linux driver (x86, x64)
  • DAHDI interface to read E1 ports data/signalling


Multi-channel interface card Quasar-16RPCX-LP (adapter) is designed for connecting E1 interfaces to servers and workstations running Linux OS. The adapter provides receiving and parsing of E1 frames, packing data into packets, buffering and transferring streams to the main computer memory in DMA mode, generating appropriate interrupts. The adapter can be used to parallelly extract information from E1 streams for the purpose of monitoring and diagnosing communication networks.
