11. RI-261525 Current and Future Requirements eVLBI is preferred to disk based observations (real time results, fault diagnosis at stations, ToO experiments, etc) Higher data rates allow increased sensitivity observations - new science Digitized data provided by:  Analogue back end: Mark 4/VLBA formatter - 1024 Mbps VSI-H - > 4096 Mbps  Digital back end: dBBC + FILA 10G, RDBE & others – 10 Gbps Third NEXPReS EVN-NREN meeting – Tuesday, 25th June 2013 Slide: 11 Time Jimmy Cullen

12. RI-261525 Current and Future Requirements Mark 5 recorders – standard for VLBI and Geodesy Current:  Mark 5A: data rates ~ 1024 Mbps to disk or network  Mark 5B: data rates ~ 2048 Mbps to disk, > to network  Mark 5C: data rates ~ 4096 Mbps to disk, > to network New (available as of 2013-06-21):  Mark 6: data rates ~ 16 Gbps continuous to disk or network (31 Gbps burst) Third NEXPReS EVN-NREN meeting – Tuesday, 25th June 2013 Slide: 12 Time

13. RI-261525 Current and Future Requirements Mark 5A/B hardware now obsolete (i.e. new units no longer available to purchase) Mark 5C/6 hardware current Mark 5* support until September 2015 Users urged to upgrade June 2012, 3 station (Efflesburg, Onsala, Yebes) eVLBI at 4 Gbps Future – more stations, more bandwidth Third NEXPReS EVN-NREN meeting – Tuesday, 25th June 2013 Slide: 13
