3276/78 Emulation Mode
MODEM OPTIONS
The HP 2625A can operate in a single or multiple modem drop communication line configura-
tion. Figure F-l shows where you must place the modems within either configuration, and
which modems the HP 2625A supports. Three modems (Bell 201C, Bell 208A, and the HP
37210T) can be used in both configurations. The communication line must be non-switched
(private, leased), and for multidrop networks, you must strap the host as the ((master" and the
remote locations as ((slaves".
