That sounds like a miscommunication; they probably meant D4, which was the framing method used before ESF came along. See the Wikipedia page about DS-1 for more information. In zaptel.conf this can be specified by using 'd4', 'sf' or 'superframe'. It is likely that this T1 is using AMI for line coding as well, because most systems that use B8ZS line coding use ESF for framing. -- Kevin P.
