Later stores from 1991 and on were outfitted with Nortel Meridian 1 Option 11 PBX systems in place of the ROLM Redwood product, which was discontinued by IBM ROLM in 1990.
The ROLM, Meridian 1 and even some 1A2 telephone systems were replaced in 2006-2007 by Safeway's Nortel BCM200 telephone systems, some of which are still in use at the Dominick's stores purchased by Roundy's and converted to Mariano's.
