The Tellco needs to supply

An RJ-47S data jack is
a RJ45S data jack attached to an RTS phone

The handset can only be used if the INP is con-
figured for manual dialing.
The modem should connect to the ACU via the RJ45S cable (HP 8120-

This connection should be made
at
the
post
connectors
of
option
3
of
the modem, and the plug
labeled
MODEM
(J2) on the ACU.
The ACU
connects
to
the
phone
line
via
a RJ45S plug (supplied with the ACU).
This connection
is made at the plug labeled
MODEM
(J2) on the ACU.
The modem and
ACU connect to the INP via the HP 30221G cable.
