Link control cards

The two LCCs (NT6X73) fill slots 17 and 18 of the HIE. Each LCC provides

an interface between eight DS30A ports from an OPM LCA shelf and the DS-1

links to the host office. The LCCs also provide an interface between the ESA

processor, when provided, and the LCM. The termination of DS-1 links on the

LCC and in the LCA appear in the following figure.
