A system and method for minimizing timeouts when enhanced services are requested through a digital home communications terminal (DHCT) requiring discovery of a service group identification (SGID) assigned to the DHCT. A service group map (SGM) includes a plurality of entries. Each entry includes a frequency, a tabulated transport stream identification (TSID), and a SGID associated with one another. The SGM has multiple occurrences of the same frequency. The entries are arranged relative to one another such that first occurrences of each SGID are interspersed alternately with one another. A match for the tabulated TSID can be found in order to determine the SGID assigned to the DHCT before tuning any frequencies that correspond to second occurrences of any of the SGIDs. The frequencies associated with particular occurrences of each SGID may be prioritized.
