Each section has capacity for 200 calling lamps and answering jacks, 160 outgoing junction and miscellaneous circuit jacks, 1000 multiple jacks and 17 cord circuits on subscribers' sections, or 33 plug-ended junction cord circuits on incoming junction sections.

For this type of equipment it is the standard practice to supply a combined main and intermediate distribution frame, which is more economical in cabling and occupies less floor space than separate frames. The latter can, however, be supplied if desired.
Note - Where an ultimate equipment of more than 2000 subscribers' lines is anticipated,
but local conditions do not permit the use of the No. 1 type, the subscribers' lines are
multipled every 6 panels, thereby giving an ultimate capacity of 3000 lines.
