Notes:

An out-of-building, same-premises, analog terminal instal-

lation requires a carbon block, gas tube, or equivalent

solid state device at each end of the interbuilding cable.

Only AT&T 500- or 2500-type terminals can be used off-

premises to a CO.

Point-to-point connections and terminals are within 33

feet of the jack.
