message to holding parties, the option
interface unit PCB (PIOU, PIOUS, or
PEPU) is suggested.
The interface PCB has a relay that can be
programmed to control a tape player every
time a call is placed on hold. When the
relay activates, the tape plays. When the
call goes off hold, the tape stops. The tape
recorder does not need to run continuously
in order for the taped message to reach
holding parties (see Relay Service).
Music-on-hold and background music can
share a music source or have individual
music sources (see Background Music).
Night Ringing Over External Page*: When the
system is in Night mode, and an incoming call
from a CO line or door phone is received, the
system can be programmed for ringing to
sound over an external speaker. When this
feature is used, persons working after-hours
are more likely to answer important calls,
especially if they work away from a telephone.
The customer-supplied external speaker
requires an option interface PCB (PIOU,
PIOUS, or PEPU) to support it. See Night
Ringing Over Selected Page Zones.
l
Any station in the system can answer the
call by dialing the Night Pickup code.
Night Ringing Over Selected Page Zones+:
CO lines can be programmed to night ring
over selected PIOU page zones via customer-
supplied paging equipment. The lines can be
divided into two groups (tenant 1 and tenant 2)
which can then be assigned to night ring over
the selected zones, 1 N 4.
Non-blocking Talk Paths*: All CO and inter-
com lines can be used at the same time. The
system can operate at full capacity at all times.
Off-premises Station: An off-premises station
is a standard telephone located off-site from
the system. Each is supported by one stan-
dard telephone interface (PSTU or PESU)
port, and normally requires a special line from
the central office. Each PSTU supports up to
eight off-premises stations, and each PESU
supports up to two off-premises stations.
Outgoing Call Restrictioti: Statidns’can be
selectively restricted from originating calls over
any number of CO lines. Only outgoing calls
are restricted. The same stations can receive
incoming calls over the restricted CO lines.
Page Interface*: Dialing a 2-digit code permits
user access to a customer-provided external
speaker through an internal 3-watt amplifier, or
a two-way 600-ohm voice path is available for
use with a customer-supplied talkback speak-
er/amplifier. The external amplifier and speak-
er are optional, and an option interface PCB
(PIOU, PIOUS, or PEPU) is required to sup-
port them.

Page can be accessed by all stations
and TIE lines (optional), but not
DISA/DISC lines.
The 3-watt amplifier is included with
either a PlOlJ or PEPU, but not on the
PIOUS.
Page Zones*: Dialing a 2-digit access code per-
mits a user to page to one of four external
zones or all zones simultaneously. External
zones are composed of customer-supplied
speaker(s) and amplifier(s). This feature is
independent of group paging, which reaches
internal station groups (see Group Paging).
The external speakers required to operate this
feature are optional. An option interface PCB
(PIOU) is required to support them. The
PIOUS or PEPU provides one external zone
only.
NOTE:
Zone page can be accessed by all stations
and TIE lines, but not DISA/DISC lines.
Pooled CO Lines: Several CO lines can be
pooled to appear under one station CO line
button. CO lines can’ be pooled in categories,
e.g., all WATS lines in one pool, all regular CO
t Requires Release 3 software.
*Available using standard or electronic telephones.
