3.39If cross-tenant traffic is denied, hunt group sta-
tions not in the same tenant group as an intercom caller
do not receive the incoming intercom call.
3.40If an outside call rings in or is transferred to a pi-
lot number that does not have hunt group station assign-
ments, the call is sent to the primary attendant. If a sta-tion user attempts to transfer an intercom call to an
invalid pilot number, the call is placed on transfer hold;the intercom call can be re-accessed on a 
keyset by
pressing IC key, or on a single-line set by hanging up to
allow the call to recall and then lifting the handset again.
A station user attempting to place an intercom call to an
invalid pilot number will hear reorder tones.
3.41When a DISA call or a call routed through the
automated attendant rings at a hunt group member’s sta-
tion, it is displayed as a direct ring-in call; however, the
system actually processes the call as a transferred call.
3.42Hunt groups can be assigned as message centers
and/or alternate message sources for individual stations.Announcement And Overflow Stations
3.43Two types of special stations can be programmed
to help calls circulate through the hunt group more effi-ciently: hunt group announcement stations and hunt
group overflow stations.
3.44Announcement and overflow stations are not in-
cluded in the hunt group list; they are individual stations
or hunt group that receive unanswered calls when all of
the hunt group stations are unavailable. Announcement
and overflow stations can be assigned to separate sta-
tions/hunt groups or they can be the same station/hunt
group. Also, each of the hunt groups can have the same
announcement and overflow stations or they can be as-
signed different stations.3.45 When the database is in the default state, all
unanswered 
direct ring-in outside calls to the hunt
group go first to the announcement station and then tothe overflow station. Unanswered calls that were
transferred to the hunt group, by default, go only to the
overflow station. However, there is a system option that
can be enabled to send 
uZf unanswered hunt group calls
fust to the announcement station and then to the
overflow station. See page 5-68 in PROGRAMMING.
3.46Announcement Stations: When the hunt group
receives a call (direct ring-in and/or transfer, depending
on programming), it rings at all stations or circulates in
linear or distributed order until it is answered or the An-
nouncement timer expires. If the timer expires, the un-
answered call is sent to one of up to three designated an-nouncement stations. (Paragraph 3.51 explains how
unanswered calls are handled.) An announcement sta-
tion can have the following 
fypes of devices:
0Playback Device: A playback device answers the
call, plays a greeting and message, and then discon-
nects from the call. The call continues ringing in the
hunt group while the playback device is handlingthe
call. If a hunt group station answers the ringing call
while it is at the playback device, the call will im-mediately leave the playback and be 
comtected to
the hunt group station.
l -Station, Hunt Group, or Voice Computer Hunt
Group: At this type of announcement station, a user
greets the caller and, if desired, may return the call to
the hunt group using the Call Transfer feature. 
The
cali will not at&nna&aUy return to the hunt group
from a 
statioh hunt group, or voice wmputer hunt
group announcement station.l Automated Attendant: An automated attendant
playback device announcement station will answer
the call, play its message, and then send the call to
the extension or pilot number selected by the caller.
Each direct ring-in call will transfer to the announce-
ment station(s) only once.3.47 To handle heavy 
incoming traffic, each hunt
group can be programmed with up to three amrounce-
ment stations (or a single hunt group as the 
armounce-
ment station). With multiple 
amrouncement stations, an
unanswered call is sent to the 
fust announcement station
on the list (after the Announcement timer expires). 
Ifthe
first announcement station is unavailable (no answer or
busy), the call is forwarded to the second 
announcementstation, and so on. 
C&e the call reaches the last an-
nouncement station on the list, it remains there until the
Forward No Answer timer expires. It then forwards to
the first announcement station on the list and starts theprocess over again until it reaches an available an-
nouncement station. (The No Answer Advance timer
determines how long a call will ring unanswered at anannouncement station before moving to the next an-
nouncement station.)
NOTE: If a 
keyset or single-line set (rather than a play-
back device) is part of a multiple 
aunouncement station
list, all calls to the station are processed according to the
programmed forward condition. The station user cannot
cancel the forward unless the station is removed 
from
the multiple announcement station list in database pro-gramming; any manual call forwarding at the station
will be overridden.3.48 Overflow Stations: When an outside call is
transferred to a hunt group by the announcement station
(or any attendant, an automated attendant, DISA, or any
station, if programmed to bypass the announcement sta-
tion), it rings at all stations or circulates in linear or 
dis-Page 4-17

tributed order until it is answered or the Overflow timer
expires. If unanswered when the timer expires, the call
is sent to an overflow station. The overflow station can
use the following types of devices:Hunt Group, Voice Computer Group, or Station:
The overflow station be another hunt group, a voice
computer group, or a station not in the group. If theoverflow station is a hunt group, voice computer
group, or a station, the call can only ring at or circu-
late through the hunt group once, unless the over-
flow station transfers it back using the Call Transfer
feature.Playback Device: If the 
overflow station is a play-
back device, the programmer can determine the
number of times (1-127 or unlimited) that the call
will be allowed to transfer back to the hunt group and
then return to the overflow station. (After the deter-
mined number of returns, the call becomes a recall.)
A playback device answers the call, plays a greeting
and message, and then disconnects from the call.
The call continues ringing in the hunt group whilethe playback device is handling the call. If a hunt
group station answers the ringing call while it is at
the playback 
device, the call will immediately leave
the playback and be connected to the hunt group sta-
tion. .
3.49A hunt group with a playback device overflow
station can be programmed, using an overflow count of0, so that 
overflow calls are sent directly back to the
transferring station when the Overflow,timer expires.
This option is set by designating that the hunt group has
a playback device overflow station, then programming
the overflow for immediate recall, or not assigning an
overflow station.Hunt Group Timers
3.50Three timers are programmed on a hunt group
by-hunt group basis: No Answer Advance timer, An-
nouncement timer, and 
Overflow timer.
0 No Answer Advance: Determines the amount of
time a call will ring at a hunt group station (unan-
swered) before advancing to the next station on the
list. The default value is 18 seconds. It can be 
pro-
g-rammed for 3-255 seconds.
0 Announcement: This determines the amount of
time a direct ring-in call will remain unanswered be-
fore it is sent to the hunt group’s announcement sta-
tion(s). The default value is 18 seconds. It can be
programmed for 
10-255 seconds.lOverflow: This determines the amount of time a
transferred outside call will circulate through the
hunt group (unanswered) before being sent to the
hunt group’s overflow station. The default value is
72 seconds. It can be programmed for 10-255 se-
conds.Unanswered Hunt Group Calls
331The path that an unanswered hunt group call fol-lows is determined by the configuration of the hunt
group, as outlined in the following paragraphs. Note that
intercom calls (direct or transferred) will not transfer to
the announcement or overflow stations, and transferred
intercom calls will not recall.l
Direct ring-in outside calls:
- Wrth a playback device amwuntmmt station:
When a call rings in to a hunt group, it circulates
through the hunt group until it is answered or the
Announcement timer expires. When this timer
expires, the unanswered call is picked up by the
designated playback device 
announcement sta-
tion that answers the call and plays a message.Meanwhile, the call continues circulating
through the hunt group (unless it has been sent to
a voice computer station). If it is answered by an
available hunt group station while the announce-
ment station is connected to the call, the call willleave the announcement station. Each call will
transfer to the amtouncement station only once.If it remains unanswered when the Overflow
timer expires, the call will be sent to the overflow
station. Or, if there is no overflow station, the call
will be sent to the recall destination station when
the Recall timer expires.
- With a non-playback announcement station:
When an unanswered direct ring-in call is sent to
a non-playback announcement station (after thehunt group Announcement timer expires), the
call remains at the announcement station until it
is answered or the caller hangs up. After the an-
nouncement station user answers, the call is pro-
cessed as a normal outside call (if desired, the
call can be manually transferred back to the hunt
group using the Call Transfer feature).
-Wthout an announcement station A direct ring-in call rings at or circulates through the hunt
group until answered or the caller hangs up; it is
not sent to the overflow station, nor does it recall
any attendant.

Iexpires, the call is picked up by a playback
device overflow station that answers the call and
plays a message. Meanwhile, the call continues
circulating through the hunt group (unless it has
been sent to a voice computer station). If the call
is answered by an available hunt group station
while the overflow station is connected to thecall, the call will leave the overflow station. If
the call remains unanswered after returning fromthe overflow station for the last time, the call
returns to the hunt group until the Overflow
timer expires, and then recalls the transferring
station.
- Wuh a non-playbackoverjbwmtio~ When an
unanswered transferred outside call is sent to a
non-playback overflow station, the call remains
at the overflow station until it is answered or un-til the Recall timer expires; it then recalls the
transferring station. If the call still remains unan-
swered, it recalls the transferring station’s atten-
dant.
- without an overjlow station: An unanswered
transferred call circulates until the hunt group
Overflow timer expires and then returns to the
transferring station. If the call still remains unan-
swered, it recalls the transferring station’s atten-
dant.
NOTE: In all cases, if the transfer came from theannouncement station or an automated atten-
dant, it recalls the primary attendant.l
To avoid the Recall timers:
-A hunt group can be assigned as its own overflow
station. The call will circulate through the hunt
group until it is answered or the caller hangs up.
3.52If a station that receives a recalling hunt group
call chooses to transfer the call back to the hunt group,the call retains its original queue position in the hunt
group. That is, it will be answered ahead of any calls thatwere received by the hunt group while the call was
recalling. It will not go back to the end of the queue.Hunt Group Remove/Replace And Do-Not-Disturb
353Hunt group stations can temporarily halt hunt
group calls by entering the Hunt Group Remove feature
code as described below. Also, the Do-Not-Disturb fea-
ture can 
bc used to block all incoming hunt group calls to
a station. Announcement stations and overflow stations
cannot block hunt group calls using the Do-Not-Disturb
or Hunt Group Remove features.3.54 The Hunt Group Remove/Replace feature can
also be controlled Corn the attendant’s station using theRemote Hunt Group Replace feature code. See page
4-111.
355When the Hunt Group Remove feature is en-
abled, the user will not hear ringing or receive the camp
on message display for calls to the hunt group unless it is
in an all-ring hunt group. In linear and distributed hunt
groups, the individual trunk key flashes only if all otherhunt group members are unavailable 
- busy, in
do-not-disturb, with calls forwarded, or with Hunt
Group Remove enabled. (Ihe station continues to re-ceive calls placed to its extension number.) All-ring
hunt group stations will receive ring flash but no display
while in Do-Not-Disturb or Hunt Group Remove mode.
Hunt group overflow and 
announcement stations cannot
block hunt group calls.3.56

Call Monitoring
357 This feature allows hunt group supervisors to
monitor the outside calls of anyone in a specified hunt
group. It can be useful in training or in evaluating the
performance of hunt group members.
NOTE: As a courtesy, hunt group members should be
notified in advance that their calls may be monitored. Inaddition, a programmable option can be enabled that
sends a tone to the station being monitored whenever the
hunt group supervisor joins an ongoing call. (Note that
call monitoring may be illegal in some locations. It is up
to the end user to ensure that use of this feature is in com-
pliance with local laws.)
3.58In database programming, each hunt group can
have one 
keyset assigned as the hunt group supervisor.
This can be any 
keyset, even if it is not a member of the
hunt group. If the supervisor is a member of the hunt
group, the Hunt Group Remove/Replace feature can be
used at any time without affecting the station monitor
ability. If desired, one 
keyset can be assigned as the su-
pervisor for more than one hunt group.

							INTER-TELdPRACTICEsIMXh2M.X 256 INS’IXLLATION & MAINTENANCE
3.59 To monitor a hunt group member’s call, the
supervisor enters the Station Call Monitoring feature
code and dials the desired extension number. The supcr-
visor is then connected to the ongoing call and can hear
both parties, but 
CaMot be heard by either one. Ifusing a
display 
keyset, the top line of the supervisor’s display
shows the hunt group member’s extension number (or
user name) and trunk number (or trunk identification).
The bottom line of the supervisor’s display shows the
hunt group member’s call cost information 
Gust as it is
on the hunt group member’s display). If the monitored
call is terminated, transferred, or placed on hold by the
hunt group member, the monitor function is 
tetminated.
3.60III the associated hunt group, the supervisor may
monitor any active CO-to-intercom call (both hunting
and non-hunting), including incoming, outgoing, and
DISA-to-intercom calls. Conference calls and calls thatdo not involve hunt group members 
camtot be moni-
tored. Also, if privacy release is enabled system-wide
and another 
keyset user joins an ongoing CO-to-inter-
com call that is being monitored (i.e., joins it by lifting
the handset and pressing the busy individual trunk key),
the call monitoring function is terminated.
3.61If the supervisor attempts to monitor a station
that is already being monitored or one that is not on an
active CO-to-intercom call, the system sends reorder
tones and allows the supervisor to dial another extension
number. If the supervisor attempts to monitor a station
that is not in the hunt group or an idle station in the hunt
group, the system sends reorder tones and cancels the
monitor feature.3.62

E.VOICE 
lUlI.JVOICE COMPUTER HUNT
GROUPS
3.63Any hunt group can be designated as a voice
computer hunt group. These hunt groups can be
assigned special dial rules that signal the voice mail unitto perform such tasks as dialing a voice mail access
number or the called station’s mailbox number. (See
page 4-16 for more information about hunt groups.)
3.64The order in which the voice mail stations
receive incoming calls (intercom, transferred, direct
ring-in, and DISA calls) is determined by a list stored in
the database. A station can appear in a single list more
than once and it can appear in multiple lists, if desired.
The station list is always checked in linear order.
3.65If a call is not answered by the first station on the
list before the No Answer Advance timer expires, thecall is sent to the next station on the list. If the call
remains unanswered when the Recall timer expires, itwill recall the designated recall designation (or the
primary attendant, if there is no recall destination
specified in the database).Recalls
3.66Arecall destination is assigned to voice comput-
er hunt groups. The recall destination can be a station or
another hunt group. If a call is transferred to a station by
the voice computer, and the applicable Transfer timer
expires,the call is sent to the designated recall
destination. If a call is transferred to a hunt group by the
voice computer, and the Overflow timer expires, the call
is sent to the designated recall destination. 
(Ifthere is no
recall destination, it is sent to the primary attendant.)DTMF Feedback Tones
3.67If a station is designated for voice mail and is
connected to a voice computer, the progress tones that
arenormally sent to the voice mail station can be
replaced with MMF “feedback” tones. These tones canbe utilized by the voice computer to determine call
statussuch as whether the call is ringing, has been
answered, has been disconnected, or if the called station
is in do-not-disturb, busy, or forwarded to an outside
telephone number. If the voice mail unit 
cannot interpret1
the 
MMF feedback tones, normal progress tones /
should be kept enabled.
I3.74 Dial rule 3-Destination extension: This dial
rule has two purposes: (1) It dials the extension of thestation that is forwarded to the voice computer hunt
group. For example, if extension 201 calls extension
202 and extension 202 forwards the call to extension
200 who forwards the call to a voice computer hunt thatuses dial rule 3, the system would send 
“200” to the
voice mail unit whenever a call was forwarded throughthe chain. This dial rule is useful for installations in
which only a few extensions in a building have
mailboxes. Assuming that only an extension that had a
voice mailbox would forward to a voice computer, the
system should dial the extension that would most likely 3.68If feedback tones are enabled, the “extended” set:
of feedback tones can also be enabled in system-wide
programming. These extended tones include codes for
indicating when a station is forwarded to another station
and when the calling party hangs up.Voice Mail/Computer Do-Not-Disturb
BlYAhWgh
3.69Calls through the voice computer (and DISA andautomated attendants) can be allowed to ring at the
station if it is in do-not-disturb. If disallowed, such callswill immediately transfer to the designated recall
destination (or to the primary attendant, if no recall
destination is specified).
3.70Allowing voice mail/computers to transfer callsto stations in do-not-disturb permits the voice mail/
computer to disconnect from the call and then make a
page announcement to alert the called party, if the voice
computer has that capability.Voice Mail/Computer Dial Rules
3.71The 256 System has the ability to support voice
computers that can process codes which give detailed
information about the status, origin, and destination of
the call, and can dial feature codes. Refer to the manual
provided with your voice computer to determine the dial
rules most suited to your specific unit, The dial rules and
codes are as follows.
3.72
Dial rule 1-Originating extension: Dials the
intercom number of the individual who initiated the
call. For example, if extension 200 called a voice
computer hunt group that used dial rule 1, the systemwould send 
“200” to the voice mail unit. This is a
general purpose dial rule; it can be used for things such
as automatically dialing the caller’s mailbox, etc.
3.73Dial rule 2 - Controlling extension: This dial
rule is meant for use with voice computer conference
features not yet developed. It dials the intercom number
of the station user that brought the voice computer into
the conference. For example, if extension 200 is talkingto extension 201 and extension 200 brings a voice
computer hunt group that uses dial rule 2 into the call
using the conference feature, the system would send“200” to the voice computer. The call could then be
recorded in mailbox number 
200 so that it can be
replayed and/or transcribed later..-Page 4-21 
						

							ii!EyEember 1994INTER-TELPRACTICESIMX/GMX 256 INST4LLATION & DANCE
have a voice mailbox. (2) It dials the intercom number of
a station when a call is transferred to the voice mail unit.For example, if extension 100 transferred a call to a
voice computer hunt group that used dial rule 3 and
entered “200” in response to the system-generated
prompt, the system would dial ‘200” when it transferred
the call to the voice computer.
3.75Diai rule 4-Original Destination Extension:
This dial rule dials the original destination of the call.
For example: If extension 200 dials a voice computer
hunt group that uses dial rule 4, the system would not
dial anything for this dial rule because there was not a
“destination.” However, if extension 201 dialed exten-
sion 200, which was forwarded to extension 202 which
was forwarded to a voice computer hunt 
group that useddial rule 4, the system would dial “200.” Similarly, if
extension 100 transferred a call to a voice computer hunt
group that used dial rule 4 and entered “200” in response
to the system-generated prompt, the system would dial
“200” when it transferred the call to the 
voice computer.3.76 Dial rule 
5-Reserved for future use
3.77 
Dial rule 6- Other IC/Controiiing IC: This
dial rule is meant for conferencing features not implem-
ented at this time. It is the opposite of dial rule 2. Where
dial rule 2 would dial the intercom number of the stationthat brought the voice computer hunt group into the
conference, this dial rule will dial the other intercom
number that is involved in conference. This dial rule is
meant to be used only during two-party calls. It is useful
for features such as a “wake-up message” in which an
operator in a hotel would receive a call from someone
wanting a wake-up call. The operator could then invokethe “wake-up” feature and enter a time for the other
person while in a conference on a call.3.78 Dial rule 7-Hunt Group Number: This dial
rule tells the voice computer which hunt group it serves
(as an 
amtouncement or overflow station). For example,if a call overflows from hunt group 1 into a voice
computer hunt group that uses dial rule 7, the system
will send “01” to the voice computer. This dial rule ismeant to be used for the voice computer performing
announcement or overflow functions for one or more
hunt groups.3.79 Dial rule 8
- Associated Tenant Group
Number: This dial rule tells the voice computer whichtenant group the originating extension 
is. in. For
example, if extension 200 is in tenant group 1 and it calls
a voice computer hunt group that uses dial rule 8, the
system will send “1” to the voice computer.3.80. Dial rule 9
- Associied Department Num-
ber: This dial rule tells the voice computer which
department the originating extension is in. For example,
if extension 200 is in department number 1 and it calls avoice computer hunt group that uses dial rule 9, the
system will send “1” to the voice computer. This dial
rule can be used in conjunction with dial rule 8.3.81 
Dial rule 10- Associated Day/Night Fiag:This dial rule will dial a “1” if the originating
extension’s tenant group is in day mode. Otherwise, itwill dial “0.” This dial rule is useful for determining
when the system is in night mode and indicating that the
attendant station is therefore unavailable.
3.82Dii ruie 11 -Associated Account Code: Thisdial rule will dial the account code, if any, that was
previously assigned to a call.3.83 Diai rule 12
- Call ‘Qpe (K/CO): This dial
rule will identify the type of call. If the call is an
intercom call, the system will dial a“1” for this dial rule.
Otherwise, this dial rule will dial a “2.”3.84 Diiruie13
- Hunt Group Queue Position:
This dial rule will identify the queue position the call
was in (first, second, third...) while waiting for the hunt
group. For example, if there was one other call ahead of
this call when it overflowed to a voice computer hunt
group that uses dial rule 13, the system would dial “2”for this dial rule. This dial rule is designed for future
features such as hunt-group overflow processing in
which the recording tells the caller, “There are five callsahead of your call.”This is especially useful for
processing hunt group calls since the call does not loseits position in the hunt group when it is sent to the
overflow station.3.85 
Dial rule 14- Hunt Group Overflow Count:
This dial rule will dial the number of times that the call
has been sent to the overflow station. If a call overflows
to a voice computer hunt group with dial rule 14, the
system will dial “1” the first time, “2” the second time,etc. This is useful for features such as hunt-group
overflow processing in which the voice computer playsdifferent messages or performs different types of
processing depending upon the number of times a caller
receives an overflow message.3.86 Dial rule 15
- Recali Source: This dial rule
dials the intercom number of the station that received a
transfer recall. The basic operation is the same as dial
rule 4, 
except.that this rule is intended for entering the
voice mail system through a recall and dial rule 4 is for
entry through direct dialing. It is useful for automated
attendant applications to make the call transfer appear
supervised.

CHTONS on page 2-2.NOTE REGARDING TRUNK SECURITY
While this system is designed to be reasonably se-cure against CO trunk misuse by outside callers,
there is no implied warranty that it is invulnerable to
unauthorixed intrusions and toll fraud. If the central
office does not provide supervision, and disconnect
the call when one party hangs up, it is possible for a
caller to remain connected to a CO trunk circuit. If
this happens, and the caller begins dialing, the call
could be placed through the 256 System and would
then be billed to the system’s owner. The system
cannot check this type of call for toll restriction andmay not register the call in SMDR This problem
could arise when a call is connected to a station,
when a call is in an unsupervised conference, when
a call is forwarded or transferred to the public net-
work, or when DISA is used for placing outgoing
CalIS.
To determine if disconnect supervision exists on atrunk, disable “standard” tones for trunks in the
database. Then place a call to an outside party using
the trunk to be tested and have the called party hang
up while you remain off hook. If there is disconnect
supervision, you will hear 256 dial tone within 30
seconds. If you hear telephone company dial tone,
there is no supervision. If supervision does not exist,contact the telephone company to determine if it
can be enabled. Centrex and loop start trunks tie-
quently do not provide disconnect supervision. Tomake a loop start trunk more secure, a 
loopto-
ground start converter can be installed. Each trunk
should be checked when it is first installed and peri-
odically rechecked to reduce the probability that the
trunk will be used for unauthorized calls.A. 
DUALTONE M-UIXI-F’REQUENCY
@TMFJ OR DIAL-PULSE SIGNALING
4.2Trunks can be designated for MMF or dial-pulsesignaling through database programming (see 
PRO-
Glb%IMlNG, page 5-103).
4.3A digital code is generated by the 
keysets and de-
coded by the system to be sent as either a 
DTMP or dial-
pulse signal, depending on the trunk designation. Key-sets and 
M’MP single-line sets can be used on either
type of trunk.
4.4A non-AIM/nondigital/non-DVK 
keyset user or 1
M’MP single-line set user can switch from dial-pulse to
M’MP signals, while using a dial-pulse trunk, by press-
ing the pound 
(#) or asterisk (*) keys. After the pound or
asterisk key is pressed, all digits that follow during that
call are sent out as 
M’MP tones. (This is useful when
calling computerized services that require a 
DIM? tele-
phone, such as automated banking.)
-1.:
NOTE: Inter-Tel AIM keysets and digital keysets do not
require this procedure; 
DTMP is enabled once the call
1
has been established. Inter-Tel/DVK keysets send both
digital code and 
lYIMP tones; therefore, this procedure
is also not required when using a DVK 
keyset.B. OUTGOING-ACCESS, ALLOWED-
ANSWER, AND RING-IN ASSIGNMENTS
4.5Each trunk group has programmed lists of stations
for outgoing-access, allowed-answer, and ring-in as-
signments for day and night modes.
0Outgoing-access assignment for a particular trunk
group permits the station user to place calls using
trunks in that trunk group.
0Allowed-answer assignment for a particular trunk
group permits the station user to answer incoming
calls on the trunks in that trunk group. Although the
call can be answered, it does not ring or flash at the
user’s station.l
Ring-in assignment for a particular trunk group per-
mits the station user to receive direct ring-in calls on
trunks in that trunk group. The station rings and, on
keysets, the individual trunk or call key flashes. Al-
lowed answer for the trunk group is automatically
assigned to a station with ring in.4.6 When 
keyset stations have outgoing-access or
ring-in assignments, the associated individual trunk
keys show the status of their trunks. Stations that do not
appear on any of the lists cannot place or directly receive
outside calls; they are limited to intercom calls, confer-
ences, transferred calls, and retrieving calls on system
hold. (A call on system hold can only be picked up at the
station that placed it on hold or at a station with an indi-
vidual trunk key for the trunk.)
4.7A private trunk group (with one or more trunks)
can be established by programming outgoing-access,
ring-in, and allowed-answer assignments for the trunk
.\‘3j
group to only one station.

RlNGlN/ANSWER PATI’ERNS4.8 Trunk groups, DID numbers, and auto ring-in
E&M trunks can be assigned to ring in to one of the fol-
lowing:l
A single station extension number
0A hunt group pilot number. DISA
0Multiple stations in a programmed ring-in/
answer pattern43
Up to 40 ring-in/answer patterns can be set up and
assigned to the trunk groups, DID numbers, and auto
ring-in E&M trunks (when the groups are not designated
for ring-in to a single station, a hunt group, or DISA).
These patterns designate the stations that will receive
direct ring-in, and/or have allowed-answer permission
for the trunks.D. RINGZONES
4.10The system power supply’s ring generator can
provide ring voltage to ring up to 20 
AGringktg single-line stations simultaneously without any noticeable
change in the ring tone. To preserve the ring tone quality,single-line stations should be divided into ring 
zone
groups.
4.llMost central office ring signals follow a 2 second
on/4 second off pattern that could be represented by this
drawing:
2424
4.12
Ring zones 1,2, and 3 use this pattern, but the
“on” times are shifted so that only one 
xone is ringing at
a time.
ZONE1 f--l
ZONE34.13 The system is constantly cycling through this
timing pattern. When a call rings in, the zone that will
receive ringing first depends on where the system is in
the cycle. For example, if a call rings when the system is
three seconds into the cycle (as shown below), the sta-
tions in 
zone 3 would begin ringing one second later.
Zone 1 would ring three seconds after the call was re-
ceived, and 
xone 2 would ring after 5 seconds.

CALLREcElvED
4.14There is an immediate-ring option that provides
ringing as soon as the call is received, regardless of thecycling described above. When the system is in the
default state, all single-line sets are set for immediate
ringing.
4.15If there are fewer than 20 AC-ringing single-line
sets that would ring at once, they can all be placed in theimmediate ring 
zone. If there are more than 20, they
should be removed 
from the immediate zone and di-
vided up among zones 1-3 so that no more than 20 sets
ring at once. Be sure to check all ring-in patterns in day
and night modes to ensure that ring 
zone assignments do
not allow more than 20 AC-ringing single-line sets to
ring at once.E. SIGNAL DEVICES
4.16The ROM Central Processing Unit (RCPU) card
contains a relay that can be used to activate an external
signaling device when a call rings in on one of the as-
signed trunks. The signal follows the 2 seconds on/4 se-
conds off pattern. Ring-in can be programmed for day
and/or night modes by placing the relay in the desired
ring-in/answer pattern(s). For more information, refer
to page 2-11 in 
SPEClFICATIONS.
F.DAY AND NIGRT MODES
4.17
There are separate lists in the database for toll re-
striction, outgoing-access, allowed-answer, and ring-in
assignments for day and night modes. When an atten-
dant enters the Night Mode feature code, the associatedtenant group uses the night lists. When the primary
attendant enters the Night Mode feature code, all tenant
groups are placed into night mode. When the primary
attendant cancels night mode, all tenant groups are in
day mode.
4.18There is no attendant recall during night mode. A
call will recall the station that transferred it or put it on
hold and will ring there until the Recall and Abandoned
Call timers expire; then the system will disconnect thecall.
Night Switch Relay
4.19The Central Processor(RCPU) card relay can beprogrammed as a night switch relay that is activated
when the system is placed in night mode. It can be used
for controlling lights, alarm systems, or other electrical
devices. The night relay 
is programmed in the database
(see page 5-73 in PROGRAMMIN
G,and page 2-10 in
SPEClFICATIONS for more information).Page 4-25

G.TRUNK RESTRICTION AND STATION
TOLL 
RESI’RICTION
4.20
Trunks and stations can be toll restricted using
several methods. Trunks can be “subject to toll restric-
tion” or “unrestricted.” They can also be identified to al-
low equal access dialing and/or to absorb digits. Stations
can be toll restricted using a combination of eight station
class of service (SCOS) restrictions and/or they can be
restricted 
from accessing specific trunk groups. Each of
the trunk and station restrictions is described separately
in the following paragraphs.
‘lhmk Restriction
4.21
Trunk group access is programmed on a station-
by-station basis. Individual stations can be allowed or
denied access to each 
trunk group separately for day and
night modes. In addition, each trunk group can also bedesignated as “subject to toll restriction” or “unre-
stricted” in database programming. (All trunks are sub-
ject to toll restriction when the system is in the default
state.) When a station user selects a 
tnmk that is desig-
nated as subject to toll restriction, the system checks the
database for that station’s SCOS. When an unrestricted
trunk is chosen, the station’s SCOS is not checked (ex-
cept 
LCR-Only restriction) and dialing is not required to
hold the trunk.4.22 Trunk groups are often programmed as
nnratricted to allow station users to have access to
reduced-cost long distance carriers, or to use ringdown
lines, dictaphones, voice mail systems, and other auxil-
iary equipment, When the installer is programming un-
restricted trunks, one of four call cost factors can be
selected to designate calls as 
free, local, ten-digit toll, oroperator/international. The selected call cost is then
used for all calls that are placed using that trunk.
‘Ihmk Group Exemption From LCR Only
4.23The trunk group may be designated as “exemptfrom Least-Cost Routing 
(LCR) only.” This allows
users with SCOS 6 (LCR Only) to directly access speci-fied trunk groups by pressing the appropriate trunk
group keys (or the ANSWER key for auto trunks) or byentering the appropriate trunk group access feature
codes. This feature is required if trunks are connected toauxiliary equipment, such as voice mail, dictation, or
ringdown equipment. When such trunks are designated
as exempt from LCR Only, stations with SCOS 6 and al-
lowed access can use the special facilities.4.24Designating a trunk group as exempt from LCR
Only also allows 
LCR-Only stations to use the call for-
ward to the public network feature. To do this, station
users can enter a trunk group access code when pro-
gramming the call forward number.4.25 The default assignment for all trunks is 
not
exempt from LCR Only. It is a system-wide designation.
That is, if a 
trunk group is subject to LCR Only, all sta-
tions with SCOS 6 are denied direct access to the trunks.
Absorbed Digits
4.26Restricted trunk groups can be programmed to
“absorb” or ignore the 
first digit(s) dialed so that only
the remaining digits are checked for toll restriction and
call cost purposes. There are two applications for this
feature: PBX 
(E&M network) installations and installa-
tions in areas where part of the local office code is ab-
sorbed by the central office.
4.27When using a dial-repeating E&M trunk, a 256station user must dial an E&M trunk access code to
reach the other telephone system, then that system’s
trunk access code to place a call using its trunks. The
256 System must absorb the second code (the one that
accesses the other system’s trunk) to allow proper tollrestriction. Without absorbed digits, the 256 System
.zamtot perform the toll restriction and call cost func-
tions. However, with absorbed digits, the 256 System
absorbs the other system’s trunk access codes, checks
the remaining digits for toll restriction, and calculates
call cost.
4.28When a number is dialed that does not match oneof the absorbed digit strings (up to 
50 strings, with a
maximum of 12 digits in each string), it is considered to
be an intercom call in the other telephone system, toll
restriction is passed, and the call is designated as a 
free
call (000) in the SMDR report. When redialing or using
call forward, the system automatically inserts a short
pause after the E&M trunk access code (which is entered
as part of the call forward number.) When speed dialing,
the speed-dial number must include the other system’s
trunk access code and a pause before the telephone num-
ber.
4.29In some rural areas, specific digits (dialed as all
or part of the local exchange) are absorbed by the central
office, thus reducing the number of digits required to
dial local calls. These digits may also be “repeatable.”
That is, they are absorbed if dialed more than once. To
determine if a central office absorbs digits and whether
they are repeatable, contact the telephone company.
