Adapter Tau-PCI/E1
Discontinued, recommended replacement is: Tau-PCI/2E1
 |
Features:
|
The Tau-PCI/E1 is an adapter board for IBM PC and compatible computers
with PCI bus. It includes two or four E1 interfaces operating at distances up
to 1.5 km. The adapter architecture is similar to the E1-XL dual modem.
Currently available models are listed in Prices. Please, contact technical support if you are unsure which model to choose.
The Tau-PCI/E1 adapter can work in one of three configurations: A, C and D.
Configuration A: Dual E1 access unit. E1 Link 0 and E1 Link 1 operate independently and have identical data pathes to the PC memory. Data transfer rate is determined by the number of timeslots used.
Configuration C: Integrating multiplexer with two data channels and E1 sub-link. The timeslots of main link (E1 Link 0) are assigned to two data channels and E1 sub-link. Two data channels to/from PC memory are supported by HDLC Controllers 0 and 1. E1 sub-link (E1 Link 1) translates remaining timeslots to the remote node. This configuration allows to split the main link data between several chained Tau-PCI/E1 nodes (up to 15) with the distance between nodes of up to 1.5 km.
Configuration D: drop-insert multiplexer. The selected timeslots of E1 links are trasferred to/from the PC memory. The remaining timeslots are translated between the E1 links.
