DULUTH, Ga. – Credit union shared branching firm Credit Union Service Corporation (CUSC) announced that credit union data processor EPL Inc., Birmingham, Ala., is the first data processor to certify to its new IST switch. CUSC said the new switch, now called Next Generation Network, improves transaction flow within shared branching and creates economies-of-scale for CUSC and its participants. With this new switch, CUSC will also offer expanded messaging capacity (the ability to flag messages to credit unions and other service centers), and greater fraud deterrent technology. EPL's certification process took 10-days and included live testing of all 33 transaction sets presently available to shared branching.
