Inward Dialing Cards 
(IDCs)353
IDCs are used for connecting direct inward dial-
ing (DID) trunks and off-premises single-line stations.
Like 
SLCs (described on page 2-12), IDCs may also beused for connecting on-premises single-line sets and
playback devices. In fact, for optimal performance, it is
recommended that voice mail units and automated at-tendant playback devices be installed on IDC circuits
