lALL or NONE: To place all trunk groups in the
facility group, select the All command button. To re-
move all 
trunk groups from the facility group, select
the None command button.
NOTE: If more than one trunk group is placed in a
facility group, the trunk groups will be accessed in
numerical order by the station users. If you wish to
have them accessed in a different order, place each
trunk group in a separate facility group, place thosefacility groups in the same route groups, and ensure
that stations have sufficient LCR advances to reach
the trunk groups. For toll restriction purposes, onlythe highest numbered trunk group in the facility
group is checked (the last trunk group iu the list).
Make sure that the highest numbered trunk group
has the desired toll restriction programming for the
entire facility group.

13. TRUNK PROGRAMMING
13.1When Trunk Programming is selected from the
Applications Menu window, the menu expands 
toshow
the following options:
Trunk Programming...
Individual Trunk
Trunk Croups, DID Croups, 
&
Ring-in/Answer Patterns
Tl Programming
13.2Each of the options and the windows they access
are described in detail in the following pages. Program
planning sheets for trunk programming are in Figure
5-24, beginning on page S-223.
A INDIvrDuALTRuNK(lNDT)13.3 When you select Individual Trunk 
from the
Trunk Rogramming menu or enter the INDI command,
the window shown on the next page appears.
13.4For each trunk, determine the 
followinginforma-tion:
Identify the trunk group to which it will belong.
Each trunk must be assigned to a trunk group. They
can be moved from group to group, but cannot be re-
moved 
from groups entirely. If any trunks will be un-used, they should be assigned to a trunk group
labeled UNUSED that does not have a ring-in as-
signment associated with it.Receive and transmit gain can be adjusted on a
trunk-by-trunk basis if voice transmit or voice
receive volume problems occur. You can adjust the
receive gain and/or the transmit gain for individual
circuits. Receive and transmit are measured from theperspective of the central office. That is, 
receive
gain adjusts the signal that is sent to the COftum the
256 System. The signal that is transmitted~m the
CO is affected by adjusting the transmit gain on the
256 System.Hybrid balance can be set to ideal, loaded, or
unloaded on a trunk-by-trunk basis. (Tl circuits and
4-wire E&M circuits cannot be hybrid balanced.)
- Ideal: The ideal balance network simulates a
600&m transmission trunk to match trunks,
which are supplied by other equipment located
within the same building, using private, copper
wire termination (e.g., an OPX supplied by an-
other PBX that does not use the public network,
or a 
Tl channel bank interface).
-Unloaded: The unloaded balance network simu-lates an 
800&m transmission trunk which
matches most CO trunks.
NOTE: The present standard for trunks from thecentral office is 900 ohms. However, 
AI&T
studies indicate that an even better match can be
obtained with 800 ohms for unloaded trunks and
1650 ohms for loaded trunks.
- Loaaixi: The loaded balance network simulates a
165O-ohm transmission trunk which more close-
ly matches the qualities of a central office trunk
that has a loading coil included in its circuitry be-cause the central office is very far from the
installation (usually over 18,000 feet).
TN&S can be loop or ground start (unless they are
on a Loop Start Card).
Aground start trunk can be programmed to begin the
call as soon as dial tone current is detected or to wait
for the Dialing Wait timer to expire.
Trunks can be set for DI’MP or dial pulse signals.
(Dial pulse is not recommended for 
LSC trunks. The
pulse circuitry on the LGC is more sophisticated and
would provide better performance.)
Each circuit on the Eh4C has two jumper straps, one
for selecting the signaling type 
(1,2,4, or 5) and one
for selecting the audio type 
(2-wire or 4-wire). The
signaling and audio type for each circuit must also be
programmed in the database.

13.5TRUNKS: To begin programming an individual
trunk, scroll through the list box until the desired trunk is
highlighted. Then continue programming the necessary
trunk features as described below.13.6 GROUP 
NUMBER: To program the trunk
group number to which this trunk is assigned, select the
Group 
# text box, and type the desired number (l-47).
13.7RECEIVE 
GAIN: To set the receive gain, enter
the gain amount in the Receive Gain text box (non-T1trunks can be -9dB to 
+3dB; Tl range is -15dB to
+15dB).
13.8TRANSMlT GAIN: To set the transmit gain,
enter the gain amount in the Transmit Gain text box
(non-T1 trunks can be -3dB to +6dB; Tl range is -15dBto 
+15dB).
NOTE: Transmit and receive gain should not be
changed unless the system is experiencing volume prob-
lems. Before changing the values contact the telephone
company to ensure that their trunks are in proper order.
FCC regulations specifies 6dB gain for CO-to-CO con-
nections. Increasing the gain above zero may place the
system in violation of the FCC regulations. These ad-
justments were intended for use with connections other
than to telephone company trunks, such as a customer-
.!provided OPXor ringdown circuits. Raising the gain too
much could cause feedback during conference calls.13.9 HYBRID BALANCE: 
(Not adable for TItrunks or 
4-w& E&M m&r) Balance can be set to
ideal, unloaded, or loaded by selecting the desired op-
tion button in the Hybrid Balance box.13.10 E&MINTERFACE: When programming an
E&M trunk, designate the signalling type (1,2,4, or 5)
and the audio type 
(2-wire or 4wire) by selecting the ap
propriate option buttons. This programming must match
the jumper settings on the EMC.
13.11START TYPE: Determine whether the trunk is
a ground start trunk or a loop start trunk by selecting the
Start 
Type box and then selecting the desired option but-
ton. The selected option button will have a black dot in
the center. This option is not available for EMC, 
TlC, or
LSC circuits.13.12 CURRENT DT DETECT: (Ground 
Start
Tanks Only) To program the trunk to begin processing
an outgoing call as soon as dial tone current is detected
(bypassing the Dialing Wait timer), select the Current
DT Detect check box (by pressing the SPACE BAR) to
place an X in it. Selecting it again will remove the X.

13.13RELAXED RING DETECT: 
Ifthe trunk does
not supply standard ringing (such as an 
H&T Dimen-
sion PBX 
OPX), select the Relaxed Ring Detect check
box (by pressing the SPACE BAR) to place an X in it.
This option is not available for LSC, EMC, or 
TlC cir-
cuits.
13.14DTMF SIGNALING: Ifthe trunk uses JYIMFsignaling, select the 
M’MF Signaling check box (by
pressing the SPACE BAR) to place an Xin it. If the trunk
uses dial pulse signaling, and the check box contains an
X, remove it by selecting the check box.13.15 IGNORE ANSWER SUPERVISION: 
This
option applies to E&M circuits only. The answer supcr-
vision signal is transmitted by the far end telephone sys-
tem to signify that the call has been answered. If this
option is enabled, any signals that are shorter than the
E&M Answer Recognition timer are ignored. This is
used in situations where false signals are being picked
up during transmission of calls. To enable the option, se-
lect the Ignore Answer Supervision check 
bdx (by press-
ing the 
SPACE BAR) to place an Xin it. To re-enable the
timer, remove the X by selecting the check box again.

B.TRUNK GROUPS, DID GROUPS, AND
RINGIN/ANSWER PAlTERNS (TRNK)
13.16When you 
select Trunk Groups, DID Croups,
and Ring-In/Answer Patterns 
from the Trnnk Program-
ming menu, or enter the TRNK command, the window
appears as shown on page 
S-108.
13.17‘Ihmk Groups: To prepare to program trunk
groups, determine the following information:
0
Trunk group description (up to 20 characters) and
display identification (up to seven characters).
The tenant group number of the attendant (other than
the primary attendant) that can place the 
tnmk group
in night mode.
The Hookflash feature can be enabled or disabled for
each trunk group. If disabled, users cannot use the
CO Hookflash feature code (330) while using the
trunks in the trunk group.
E&M trunks can be placed in trunk groups. 
E&M
trunk groups may be designated as immediate start,
wink start, or delay start in database programming.
The call routing can be programmed to automatical-
ly ring in (auto ring in) to the system’s attendant or to
allow callers to dial extensions as desired (dial re-peating). If callers are allowed to dial extension
numbers, the trunk group programming must indi-
cate whether the 256 System will send dial tone. Re-order tones on 
E&M trunk groups can be
programmed to be sent as continuous tones or a short
burst of reorder tone; a short burst allows the user to
try again, continuous tones prevent the user 
from
further dialing.
Page 
5-106
Determine if the trunk group contains all incoming-
only 
tnmks. Certain types of trunks, such as incom-
ing 
Wm, need to be marked as “incoming-only” so
that the system will recognize the lines during pow-
er-up and/or testing. (This is because, on these types
of lines, ground signal is not returned on Tip and the
system 
cannot power up the trunk unless this option
is enabled.)
Lists of stations with outgoing access for each trunk
group.The music-on-hold 
channel (channel one or two,
tick-tones, or silence) that will be used when callers
on that trunk group are placed on hold.Ring-in type is determined separately for day and
night modes. Ring in can be the same for both
modes, or any combination of the following can be
used:
- Single: If the trunk group will ring at a single sta---T y
tion, determine the circuit or extension number
of the station.2
- Multiple: If the trunk group will ring in to more
than one station, list those stations by circuit or
extension number in a ring-in/answer pattern and
assign the pattern to the trunk group.
--~Group:Ifthetrunkgroupwillringintoa
hunt group, determine the hunt group’s number.
- DZU: If the trunk group is to be used for DISAand a security code is desired, determine the
four-digit security codes (day and night) and de-
termine if the security codes will be needed forintercom access. If using 
Exmuied software,also determine the toll restrictions, for each
DISA trunk group, that will be applied when an
outgoing call is placed.I
NOTE: While DISA is designed to be reason-
ably secure against misuse by outside callers,
there is no implied warranty that it is invulner-
able to unauthorized intrusions. The installer 
and
owner of the system should ensure that proper se-
curity measures have been taken to prevent out-side callers 
from accessing and misusing
outgoing lines for unauthorized calls.
Determine if the trunk group is subject to toll restric-
tion. If the trunk group is not subject to toll restric-tion, the station class of service (SCOS) is not
checked (except LCR-Only restriction) when a
trunk in the group is used.
The trunk group can be exempt 
from, or subject to,
the LCR only restriction. 
Jfexempt from LCR only,
stations with SCOS 6 (LCR Only) using the proper
access code can directly access the trunks. If subject
to 
LCR only, stations with SCOS 6 can access the
trunk only if it is part of an LCR facility group.For unrestricted trunk groups, determine the call
cost rate to be used for calls placed on the trnnks.
Call cost can 
be: free, local rate, ten-digit rate, or op
erator-assisted/international rate.I
Truuk groups that are subject to toll restriction canbe designated as equal access trunks to allow
10xXx and 1OlXXXX codes to be used when
accessing long distance carriers.
Trunk groups can be programmed to absorb digitsfor PBX installations and installations in areas
where the first digit(s) of the office code are ab-
sorbed. If absorbed digits are used, determine if they
are repeatable (that is, they are absorbed if the 
ab-
sorbed digit string is dialed repeatedly).

13.18DID Groups: There can be up to 11 direct in-
ward dialing (DID) groups, including the DID group for
unused trunks). For each DID group, determine the fol-
lowing information:
0
0
0
0
0
I
I
DID group description (up to 20 characters) and dis-
play identification (up to seven characters) for each
DID number.
List the trunks that will be in the DID group by cir-
cuit number.
For each DID group, note the base number and the
dialed number range that will be received from the
central office. For example, if the customer has pur-
chased a block of 100 DID numbers starting with
961-1000, the base number is 
“%l” the start digits
are 
“1000” and the number of entries is “100.”Start type for the DID group can be immediate,
wink, or delay depending on the type of DID trunks
ordered from the telephone company.
If the DID group is to be used for DISA and a security
code is desired, determine the four-digit (seven-digit
in Exfenakl software) security codes for day and
night modes. Also determine if the security codeswill be needed for intercom access. If using Ex-
tended software, also determine the toll restrictions
that will be applied when an outgoing call is placed.NOTE: While DISA is designed to be reasonably
secure against misuse by outside callers, there is no
implied warranty that it is invulnerable to unautho-rized intrusions. The installer and owner of the 
SyS-tern should ensure that proper security measures
have been taken to prevent outside callers 
from
accessing and misusing outgoing lines for unautho-
rized calls.
0Ring-in type (the destination of the DID number) isdetermined separately for day and night modes.
Ring in can be the same for both modes, or any com-
bination of the following can be used:
- Single: If the DID number will ring at a single
station, determine the circuit or extension num-
ber of the station.
- Multiple: If the DID number will ring in to more
than one station, list those stations by circuit orextension number in a ring-in/ answer pattern
that is assigned to the DID number.
- Huuf Group: If the DID number will ring in to a
hunt group, determine the hunt group’s number.
- DZU: The DID number can be used for DISA.NOTE: If a DID number is not given a ring-in
destination, it will ring at the primary attendant’s
station in both day and night modes.
13.19Ring-In/Answer Patterns: Up to 40 ring-in/
answer patterns can be set up and assigned to the trunk
groups and DID numbers. These patterns designate the
stations and relays that will receive direct ring-in, or sta-
tions that have allowed-answer permission, for the trunk
group. Each pattern can be given a name of up to 
20
characters.

Group check box by selecting it. The following sections
of the window change from gray to black to allow you to
continue programming the E&M trunk group.NOTE: Whenever you change the status of this check
box, a warning appears that tells you that changing the
trunk group type will exclude all trunks 
from this group.
If you wish to continue, select the Yes command button.
To cancel the change, select No.
0 CALL ROUTING: Determine whether incoming
calls on these trunks will be sent directly to a prede-termined destination, such as the attendant (Auto
Ring-In), or if callers will be allowed to dial num-
bers to reach extensions (Dial Repeating). Place a
dot in the desired option button by selecting it. (De-
faults to Dial Repeating.)l
REORDER TONE: Determine whether the reorder
tone heard by users will be a short burst of tones or
continuous reorder tones (a short burst of tone will
allow the caller to try again, a continuous burst re-
quires the caller to hang up). Place a dot in the de-sired option button by selecting it. (Defaults to

(Dial-repeating trunk groups should have this option
enabled.) If disabled, the 256 System automatically
performs the handshake and then waits to receive
digits. To enable the 256 System to send dial tone,
place an X in the Return Dial Tone check box by se-lecting it. (In the default state, this option is en-
abled.)l DID DIGIT TRANSLATION: There are 
~N&S
available that function like a DID trunk for incoming
calls and an E&M trunk for outgoing calls. For an
outgoing call, the trunk directly accesses the central
office or long distance provider and allows the usual
E&M calls to be placed. For incoming DID-type
calls, the trunk receives the incoming call and thenwaits for 
24 additional digits to be dialed. These
digits must correspond to the digits in a DID table so
that the 256 System will know where to send the call.
(The DID digit translation tables are programmed in
theDIDGroupwindowshownonpage5-115.)Toen-
able DID digit translation for the trunk group, locate
the desired DID group by scrolling through the DID
Translation list box. The position of the highlight bar
indicates the selected group. If digit translation is
not needed, highlight “No DID Translation.”
13.29ONE-WAY INCOMING ONLY: If the trunk
group contains incoming-only lines, place an X in the
One-Way Incoming Only check box by selecting it. To
remove the X, select it again. When you place the X in
the check box, the system checks whether any stations
have outgoing access for that trunk group. If there are
stations with outgoing access, a window appears that
asks if you wish to delete the outgoing-access assign-
ments for those stations. Select the Yes command button
to remove the outgoing-access assignments, or select
the No command button to cancel the One-Way Incom-
ing Only designation.
