9.2. V11-V35
interface:
The AJ 2885P (except FT model) modem provides a terminal interface configurable in V28 or
V11 through the J12 to J21 jumpers.
The jumpers in position 1-2 set a V28 signal. In position 2-3 they set a V11 signal.
To allow any V11 signal (mixed V28 and V11 signals), the J9 jumper must be set in position 2-
3.
The following picture describes the confirmation of the interface.
